    Request to the Department of Energy and Climate Change

    Re : Policy and Strategy for North Sea Natural Gas Fields Depletion

    Previous Freedom of Information Request Reference : 14/0672
    Previous Freedom of Information Request Dated : 27th April 2014

    Dear Madam / Sir,

    Thank you for your reply to my previous Freedom of Information Request, which has prompted me to ask for further information in order to fully comprehend the prospects for manufactured gas in British energy policy.

    1. The Potential for Synthetic Natural Gas (SNG)

    In the reply to my previous Freedom of Information Request of 27th April 2014, with the reference number 14/0672, the following statement was offered :-

    “Furthermore, we have doubts that synthetic natural gas production under current technologies could meet any significant shortfall of gas supply either economically or in sufficient quantity.”

    Under the Freedom of Information Act of 2000, please could you send me documentation such as interim and final reports, reviews and feasibility studies on which you base your lack of confidence in the potential of the current technologies for Synthetic Natural Gas to meet any significant shortfall of gas supply either economically or in terms of quantity.

    In particular, as the production of Renewable Hydrogen is a key element of several suggested “Power to Gas” Synthetic Natural Gas system designs, I would like to have copies of final reports, reviews and studies in relation to the GridGas project, a feasibility study for which was funded by the Department of Energy and Climate Change (DECC), and which had partners in ITM Power, (Royal Dutch) Shell, Kiwa (GASTEC), National Grid and The Scottish Hydrogen and Fuel Cell Association (SHFCA).

    I should also especially like to have copies of interim and final reports and reviews from the feasibility study into the Production of Synthetic Methane, conducted by ITM Power, as funded by DECC under the Carbon Capture and Storage Innovation Competition, in a consortium with Scottish and Southern Energy (SSE), Scotia Gas Networks, Logan Energy Ltd and Kiwa GASTEC at CRE.

    I should also like to know which designs for Synthetic Natural Gas systems you have considered, which will entail you furnishing me with diagrams and other engineering information for process elements and plant equipment, to allow me to understand which gas processing configurations you have considered, and which you have dismissed.

    I would also like to know what your estimates are for “spare” wind and solar power hours of generation by 2025 in the UK. This excess generation, whereby power demand does not meet power supply from variable renewable electricity, is crucial to anticipate as this is a key input for “Power to Gas” designs.

    I should also like to see your assessment of the German Energy Agency (dena) “Power to Gas” Strategy and your analysis of how this compares to the British situation and prospects.

    As regards relative economic values of different sources of gas energy fuel, I would like to receive information about your analyses of the near-term gas market, and the likelihood of price rises in Natural Gas, and competition in the market from new Natural Gas customers, especially in light of the imminent closure of coal-fired power plants due to the European Community’s Large Combustion Plant Directive (LPCD) and the Industrial Emissions Directive (IED).

    2. The Potential for Natural Gas Supply Shocks

    In the reply to my previous Freedom of Information Request of 27th April 2014, given the reference number 14/0672, the following statements were made :-

    “It is the government’s stance that developments in the gas industry should be market-led, underpinned by robust price signals. This is a model which has ensured that UK domestic and small business consumers have never faced gas shortages and even industry-level warnings are rare. This approach has also delivered significant investment in gas infrastructure, in response to declining production from the UK Continental Shelf, and we are well placed to absorb supply shocks, with a diverse range of suppliers, routes and sources. Discounting our indigenous production, which is still responsible for around half of our annual gas demand, UK import infrastructure can meet 189% of annual demand. This resilience to supply shocks is demonstrated by Ofgem’s 2012 Gas Security of Supply report which found that in a normal winter we would have to lose 50% of non-storage supplies for there to be an interruption to gas supplies to large industrial users and/or the power sector, and between 60% and 70% of all gas sources for there to be an interruption of supplies to domestic customers – equivalent to losing all LNG supply, all imports from the Continent and 50% of our production at the same time.”

    Under the Freedom of Information Act 2000, please can you supply me copies of, or links to, documents that specify analysis of what kinds of “robust price signals” you are referring to, and how these are achieved. In particular, I should like to know if you mean the ebb and flow of gas prices under market conditions, or whether you consider regulatory instruments, for example, carbon pricing, or economic policy, such as tax breaks or subsidies for gas producers, to be at least part of the source of the “robust price signals” you expect.

    In particular, I should like to know from your internal reports how you view the impact of the Capacity Mechanism on the price of Natural Gas in the UK – the Capacity Mechanism having been proposed to keep gas-fired power plants from closure, in order to be available to balance electrical grid fluctuations.

    I should also like you to supply me with copies of your internal reviews of the impact on imported Natural Gas prices from events unrelated to market conditions, such as the outcomes of warfare, or political manoeuvres, and whether these price shocks could contribute to “supply shocks”.

    I should also like to have sight of reports or other documentation that outlines analysis of risks of “supply shock” in gas supply, for instance, what circumstances are considered capable of causing a 50%, 60% or 70% drop in non-domestic gas supplies, causing a loss of imported Liquified Natural Gas, or imported pipeline Natural Gas. Please can you also provide me with reports, or links to reports, that show the analysis of circumstances that would cause a loss of 50% of Natural Gas from the North Sea and other production areas in the United Kingdom; including an analysis of risks of a trade war between a putative newly-independent Scotland and its gas customer England, given that most Natural Gas consumption is south of the border.

    Please may I also have information that details your analyses of the decline in Natural Gas production from the North Sea, including from territorial waters outside the UK, a calculation of depletion rates in reserves, and the projection for decline in production.

    I should also like to have sight of the documents on which you base your calculations of depletion of Natural Gas reserves across Eurasia, Asia, North Africa and the Middle East, and the risks to production levels according [to] the passage of time.

    As a corollary, I would like to have sight of the documents on which you base your analysis of future changes in market demand for Natural Gas across Eurasia, Asia, North Africa and the Middle East, especially considering new trade relationships between China and Russia, and China and the Middle East.

    Thank you for your attention to my request for information.

    Regards,

  • This Too Will Fail

    Posted on May 24th, 2014 Jo 1 comment

    I will probably fail to make myself understood, yet again, but here goes…

    The reasons the United Nations Climate Change process is failing are :-

    1.   The wrong people are being asked to shoulder responsibility

    It is a well-rumoured possibility that the fossil fuel industry makes sure it has sympathisers and lobbyists at the United Nations Framework Convention on Climate Change (UNFCCC) conferences. It is only natural that they should want to monitor proceedings, and influence outcomes. But interventions by the energy sector has a much wider scope. Delegates from the countries with national oil and gas companies are key actors at UNFCCC conferences. Their national interests are closely bound to their fossil fuel exports. Many other countries understand their national interest is bound to the success of energy sector companies operating within their borders. Still others have governments with energy policy virtually dictated by international energy corporations. Yet when the UNFCCC discusses climate change, the only obligations discussed are those of nations – the parties to any treaty are the governments and regimes of the world. The UNFCCC does not hold oil and gas (and coal) companies to account. BP and Shell (and Exxon and Chevron and Total and GDF Suez and Eni and so on) are not asked to make undertakings at the annual climate talks. Governments are hoped to forge a treaty, but this treaty will create no leverage for change; no framework of accountability amongst those who produce oil, gas and coal.

    2.   The right people are not in the room

    It’s all very well for Governments to commit to a treaty, but they cannot implement it. Yes, their citizens can make a certain amount of changes, and reduce their carbon emissions through controlling their energy consumption and their material acquisitions. But that’s not the whole story. Energy has to be decarbonised at source. There are technological solutions to climate change, and they require the deployment of renewable energy systems. The people who can implement renewable energy schemes should be part of the UNFCCC process; the engineering companies who make wind turbines, solar photovoltaic panels, the people who can build Renewable Gas systems. Companies such as Siemens, GE, Alstom. Energy engineering project companies. Chemical engineering companies.

    3.   The economists are still in the building

    In the United Kingdom (what will we call it if Scotland becomes independent ? And what will the word “British” then mean ?) the Parliament passed the Climate Change Act. But this legislation is meaningless without a means to implement the Carbon Budgets it institutes. The British example is just a minor parallel to the UNFCCC situation – how can a global climate treaty be made to work ? Most of the notions the economists have put forward so far to incentivise energy demand reduction and stimulate low carbon energy production have failed to achieve much. Carbon trading ! Carbon pricing ! All rather ineffective. Plus, there’s the residual notion of different treatment for developed and developing nations, which is a road to nowhere.

    4.   Unilateral action is frowned upon

    Apparently, since Climate Change is a global problem, we all have to act in a united fashion to solve it. But that’s too hard to ask, at least to start with. When countries or regions take it upon themselves to act independently, the policy community seem to counsel against it. There are a few exceptions, such as the C40 process, where individual cities are praised for independent action, but as soon as the European Community sets up something that looks like a border tax on carbon, that’s a no-no. Everybody is asked to be part of a global process, but it’s almost too hard to get anything done within this framework.

    5.   Civil Society is hamstrung and tongue-tied

    There is very little that people groups can achieve within the UNFCCC process, because there is a disconnect between the negotiations and practical action. The framework of the treaty discussions does not encompass the real change makers. The UNFCCC does not build the foundation for the architecture of a new green economy, because it only addresses itself to garnering commitments from parties that cannot fulfill them. Civil Society ask for an egg sandwich and they are given a sandy eggshell. If Civil Society groups call for technology, they are given a carbon credit framework. If they call for differential investment strategies that can discredit carbon dependency, they are given an opportunity to put money into the global adaptation fund.

  • Positively Against Negative Campaigning

    Posted on May 24th, 2014 Jo 4 comments

    How to organise a political campaign around Climate Change : ask a group of well-fed, well-meaning, Guardian-reading, philanthropic do-gooders into the room to adopt the lowest common denominator action plan. Now, as a well-fed, well-meaning, Guardian-reading (well, sometimes), philanthropic do-gooder myself, I can expect to be invited to attend such meetings on a regular basis. And always, I find myself frustrated by the outcomes : the same insipid (but with well-designed artwork) calls to our publics and networks to support something with an email registration, a signed postcard, a fistful of dollars, a visit to a public meeting of no consequence, or a letter to our democratic representative. No output except maybe some numbers. Numbers to support a government decision, perhaps, or numbers to indicate what kind of messaging people need in future.

    I mean, with the Fair Trade campaign, at least there was some kind of real outcome. Trade Justice advocates manned stall tables at churches, local venues, public events, and got money flowing to the international co-operatives, building up the trade, making the projects happen, providing schooling and health and aspirations in the target countries. But compare that to the Make Poverty History campaign which was largely run to support a vain top-level political attempt to garner international funding promises for social, health and economic development. Too big to succeed. No direct line between supporting the campaign and actually supporting the targets. Passing round the hat to developed, industrialised countries for a fund to support change in developing, over-exploited countries just isn’t going to work. Lord Nicholas Stern tried to ask for $100 billion a year by 2020 for Climate Change adaptation. This has skidded to a halt, as far as I know. The economic upheavals, don’t you know ?

    And here we are again. The United Nations Framework Convention on Climate Change (UNFCCC), which launched the Intergovernmental Panel on Climate Change (IPCC) reports on climate change, oh, so, long, ago, through the person of its most charismatic and approachable Executive Secretary, Christiana Figueres, is calling for support for a global Climate Change treaty in 2015. Elements of this treaty, being drafted this year, will, no doubt, use the policy memes of the past – passing round the titfer begging for a couple of billion squid for poor, hungry people suffering from floods and droughts; proposing some kind of carbon pricing/taxing/trading scheme to conjure accounting bean solutions; trying to implement an agreement around parts per million by volume of atmospheric carbon dioxide; trying to divide the carbon cake between the rich and the poor.

    Somehow, we believe, that being united around this proposed treaty, few of which have any control over the contents of, will bring us progress.

    What can any of us do to really have input into the building of a viable future ? Christiana – for she is now known frequently only by her first name – has called for numbers – a measure of support for the United Nations process. She has also let it be known that if there is a substantial number of people who, with their organisations, take their investments out of fossil fuels, then this could contribute to the mood of the moment. Those who are advocating divestment are yet small in number, and I fear that they will continue to be marginal, partly because of the language that is being used.

    First of all, there are the Carbon Disclosers. Their approach is to conjure a spectre of the “Carbon Bubble” – making a case that investments in carbon dioxide-rich enterprises could well end up being stranded by their assets, either because of wrong assumptions about viable remaining resources of fossil fuels, or because of wrong assumptions about the inability of governments to institute carbon pricing. Well, obviously, governments will find it hard to implement effective carbon pricing, because governments are in bed with the energy industry. Politically, governments need to keep big industry sweet. No surprise there. And it’s in everybody’s interests if Emperor Oil and Prince Regent Natural Gas are still wearing clothes. In the minds of the energy industry, we still have a good four decades of healthy fossil fuel assets. Royal Dutch Shell’s CEO can therefore confidently say at a public AGM that There Is No Carbon Bubble. The Carbon Discloser language is not working, it seems, as any kind of convincer, except to a small core of the concerned.

    And then there are the Carbon Voices. These are the people reached by email campaigns who have no real idea how to do anything practical to affect change on carbon dioxide emissions, but they have been touched by the message of the risks of climate change and they want to be seen to be supporting action, although it’s not clear what action will, or indeed can, be taken. Well-designed brochures printed on stiff recycled paper with non-toxic inks will pour through their doors and Inboxes. Tick it. Send it back. Sign it. Send it on. Maybe even send some cash to support the campaign. This language is not achieving anything except guilt.

    And then there are the Carbon Divestors. These are extremely small marginal voices who are taking a firm stand on where their organisations invest their capital. The language is utterly dated. The fossil fuel industry are evil, apparently, and investing in fossil fuels is immoral. It is negative campaigning, and I don’t think it stands a chance of making real change. It will not achieve its goal of being prophetic in nature – bearing witness to the future – because of the non-inclusive language. Carbon Voices reached by Carbon Divestor messages will in the main refuse to respond, I feel.

    Political action on Climate Change, and by that I mean real action based on solid decisions, often taken by individuals or small groups, has so far been under-the-radar, under-the-counter, much like the Fair Trade campaign was until it burst forth into the glorious day of social acceptability and supermarket supply chains. You have the cyclists, the Transition Towners, the solar power enthusiasts. Yet to get real, significant, economic-scale transition, you need Energy Change – that is, a total transformation of the energy supply and use systems. It’s all very well for a small group of Methodist churches to pull their pension funds from investments in BP and Shell, but it’s another thing entirely to engage BP and Shell in an action plan to diversify out of petroleum oil and Natural Gas.

    Here below are my email words in my feeble attempt to challenge the brain of Britain’s charitable campaigns on what exactly is intended for the rallying cry leading up to Paris 2015. I can pretty much guarantee you won’t like it – but you have to remember – I’m not breaking ranks, I’m trying to get beyond the Climate Change campaigning and lobbying that is currently in play, which I regard as ineffective. I don’t expect a miraculous breakthrough in communication, the least I can do is sow the seed of an alternative. I expect I could be dis-invited from the NGO party, but it doesn’t appear to be a really open forum, merely a token consultation to build up energy for a plan already decided. If so, there are probably more important things I could be doing with my time than wasting hours and hours and so much effort on somebody else’s insipid and vapid agenda.

    I expect people might find that attitude upsetting. If so, you know, I still love you all, but you need to do better.


    [...]

    A lot of campaigning over the last 30 years has been very negative and divisive, and frequently ends in psychological stalemate. Those who are cast as the Bad Guys cannot respond to the campaigning because they cannot admit to their supporters/employees/shareholders that the campaigners are “right”. Joe Average cannot support a negative campaign as there is no apparent way to make change happen by being so oppositional, and because the ask is too difficult, impractical, insupportable. [Or there is simply too much confusion or cognitive dissonance.]

    One of the things that was brought back from the [...] working group breakout on [...] to the plenary feedback session was that there should be some positive things about this campaign on future-appropriate investment. I think [...] mentioned the obvious one of saying effectively “we are backing out of these investments in order to invest in things that are more in line with our values” – with the implicit encouragement for fossil fuel companies to demonstrate that they can be in line with our values and that they are moving towards that. There was some discussion that there are no bulk Good Guy investment funds, that people couldn’t move investments in bulk, although some said there are. [...] mentioned Ethex.

    Clearly fossil fuel production companies are going to find it hard to switch from oil and gas to renewable electricity, so that’s not a doable we can ask them for. Several large fossil fuel companies, such as BP, have tried doing wind and solar power, but they have either shuttered those business units, or not let them replace their fossil fuel activities.

    [...] asked if the [divestment] campaign included a call for CCS – Carbon Capture and Storage – and [...] referred to [...] which showed where CCS is listed in a box on indicators of a “good” fossil fuel energy company.

    I questioned whether the fossil fuel companies really want to do CCS – and that they have simply been waiting for government subsidies or demonstration funds to do it. (And anyway, you can’t do CCS on a car.)

    I think I said in the meeting that fossil fuel producer companies can save themselves and save the planet by adopting Renewable Gas – so methods for Carbon Capture and Utilisation (CCU) or “carbon recycling”. Plus, they could be making low carbon gas by using biomass inputs. Most of the kit they need is already widely installed at petrorefineries. So – they get to keep producing gas and oil, but it’s renewably and sustainably sourced with low net carbon dioxide emissions. That could be turned into a positive, collaborative ask, I reckon, because we could all invest in that, the fossil fuel companies and their shareholders.

    Anyway, I hope you did record something urging a call to positive action and positive engagement, because we need the co-operation of the fossil fuel companies to make appropriate levels of change to the energy system. Either that, or they go out of business and we face social turmoil.

    If you don’t understand why this is relevant, that’s OK. If you don’t understand why a straight negative campaign is a turn-off to many people (including those in the fossil fuel industry), well, I could role play that with you. If you don’t understand what I’m talking about when I talk about Renewable Gas, come and talk to me about it again in 5 years, when it should be common knowledge. If you don’t understand why I am encouraging positive collaboration, when negative campaigning is so popular and marketable to your core segments, then I will resort to the definition of insanity – which is to keep doing the same things, expecting a different result.

    I’m sick and tired of negative campaigning. Isn’t there a more productive thing to be doing ?

    There are no enemies. There are no enemies. There are no enemies.

    ——-

    As far as I understand the situation, both the [...] and [...] campaigns are negative. They don’t appear to offer any positive routes out of the problem that could engage the fossil fuel companies in taking up the baton of Energy Change. If that is indeed the main focus of [...] and [...] efforts, then I fear they will fail. Their work will simply be a repeat of the negative campaigning of the last 30 years – a small niche group will take up now-digital placards and deploy righteous, holy social media anger, and that will be all.

    Since you understand this problem, then I would suggest you could spend more time and trouble helping them to see a new way. You are, after all, a communications expert. And so you know that even Adolf Hitler used positive, convening, gathering techniques of propaganda to create power – and reserved the negative campaigning for easily-marginalised vulnerable groups to pile the bile and blame on.

    Have a nicer day,

    —–

    The important thing as far as I understand it is that the “campaigning” organisations need to offer well-researched alternatives, instead of just complaining about the way things are. And these well-researched alternatives should not just be the token sops flung at the NGOs and UN by the fossil fuel companies. What do I mean ?

    Well, let’s take Carbon Capture and Storage (CCS). The injection of carbon dioxide into old oil and gas caverns was originally proposed for Enhanced Oil Recovery (EOR) – that is – getting more oil and gas out the ground by pumping gas down there – a bit like fracking, but with gas instead of liquid. The idea was that the expense of CCS would be compensated for by the new production of oil and gas – however, the CCS EOR effect has shown to be only temporary. So now the major oil and gas companies say they support carbon pricing (either by taxation or trading), to make CCS move forward. States and federations have given them money to do it. I think the evidence shows that carbon pricing cannot be implemented at a sufficiently high level to incentivise CCS, therefore CCS is a non-answer. Why has [...] not investigated this ? CCS is a meme, but not necessarily part of the carbon dioxide solution. Not even the UNFCCC IPCC reports reckon that much CCS can be done before 2040. So, why does CCS appear in the [...] criteria for a “good” fossil fuel company ? Because it’s sufficiently weak as a proposal, and sufficiently far enough ahead that the fossil fuel companies can claim they are “capture ready”, and in the Good Book, but in reality are doing nothing.

    Non-starters don’t just appear from fossil fuel companies. From my point of view, another example of running at and latching on to things that cannot help was the support of the GDR – Greenhouse Development Rights, of which there has been severe critique in policy circles, but the NGOs just wrote it into their policy proposals without thinking about it. There is no way that the emissions budgets set out in the GDR policy could ever get put into practice. For a start, there is no real economic reason to divide the world into developing and developed nations (Kyoto [Protocol]‘s Annex I and Annex II).

    If you give me some links, I’m going to look over your [...] and think about it.

    I think that if a campaign really wants to get anywhere with fossil fuel companies, instead of being shunted into a siding, it needs to know properly what the zero carbon transition pathways really are. Unequal partners do not make for a productive engagement, I reckon.

    —–

    I’m sorry to say that this still appears to be negative campaigning – fossil fuel companies are “bad”; and we need to pull our money out of fossil fuel companies and put it in other “good” companies. Where’s the collective, co-operative effort undertaken with the fossil fuel companies ? What’s your proposal for helping to support them in evolving ? Do you know how they can technologically transition from using fossil fuels to non-fossil fuels ? And how are you communicating that with them ?

    ——

    They call me the “Paradigm Buster”. I’m not sure if “the group” is open to even just peeking into that kind of approach, let alone “exploring” it. The action points on the corporate agenda could so easily slip back into the methods and styles of the past. Identify a suffering group. Build a theory of justice. Demand reparation. Make Poverty History clearly had its victims and its saviours. Climate change, in my view, requires a far different treatment. Polar bears cannot substitute for starving African children. And not even when climate change makes African children starve, can they inspire the kind of action that climate change demands. A boycott campaign without a genuine alternative will only touch a small demographic. Whatever “the group” agrees to do, I want it to succeed, but by rehashing the campaigning strategies and psychology of the past, I fear it will fail. Even by adopting the most recent thinking on change, such as Common Cause, [it] is not going to surmount the difficulties of trying to base calls to action on the basis of us-and-them thinking – polar thinking – the good guys versus the bad guys – the body politic David versus the fossil fuel company Goliath. By challenging this, I risk alienation, but I am bound to adhere to what I see as the truth. Climate change is not like any other disaster, aid or emergency campaign. You can’t just put your money in the [collecting tin] and pray the problem will go away with the help of the right agencies. Complaining about the “Carbon Bubble” and pulling your savings from fossil fuels is not going to re-orient the oil and gas companies. The routes to effective change require a much more comprehensive structure of actions. And far more engagement that agreeing to be a flag waver for whichever Government policy is on the table. I suppose it’s too much to ask to see some representation from the energy industry in “the group”, or at least [...] leaders who still believe in the fossil fuel narratives, to take into account their agenda and their perspective, and a readiness to try positive collaborative change with all the relevant stakeholders ?

  • Nigel Lawson : Unreferenced & Ill-Informed ?

    Posted on May 8th, 2014 Jo No comments

    An appeal was issued by David Andrews of the Claverton Energy Research Group, to respond to the Bath Lecture given by Nigel Lawson :-

    “Dear All, this group is not meant to be a mere venting of frustration and opinion at what is perceived to be poor policy. So what would be really useful is to have the Lawson spiel with the countering fact interspersed. I can then publish this on the Claverton web site which does get a lot of hits and appears to be quite influential. Can I therefore first thank Ed Sears for making a good effort, but ask him to copy his bits into the Lawson article at the appropriate point. Then circulate it and get others to add in bits. Otherwise these good thoughts will simply be lost in the wind. Dave”

    My reply of today :-

    “Dear Dave, I don’t have time at the moment to answer all of Nigel Lawson’s layman ruminations, but I have written a few comments here (see below) which begin to give vent to frustration typical of that which his tactics cause in the minds of people who have some acquaintance with the actual science. The sheer volume of his output suggests an attempt to filibuster proper debate rather than foster it. To make life more complicated to those who wish to answer his what I think are absurd notions, he gives no accurate references to his supposed facts or cites any accredited, peer-reviewed documentation that could back up his various emotive generalisations and what appear to be aspersions. Regards, jo.”

    Nigel Lawson: The Bath Lecture

    Climate Alarmism Is A Belief System And Needs To Be Evaluated As Such

    Nigel Lawson: Cool It

    Standpoint, May 2014

    This essay is based on the text of a speech given to the Institute for Sustainable Energy and the Environment at the University of Bath.

    There is something odd about the global warming debate — or the climate change debate, as we are now expected to call it, since global warming has for the time being come to a halt.

    [ joabbess.com : Contrary to what Nigel Lawson is claiming, there is no pause - global warming continues unabated. Of this there can be no doubt. All of the data that has been assessed - and there is a lot of it - confirms the theoretical framework - so it is odd that Nigel Lawson states otherwise, seemingly without any evidence to substantiate his assertion. Nigel Lawson appears to be taking advantage of fluctuations, or short-term wrinkles, in the records of air temperatures close to the Earth, to claim that up is down, dark is light and that truth is in error. Why are temperatures in the atmosphere close to the Earth's surface, or "surface temperatures", subject to variability ? Because heat can flow through matter, is the short answer. The longer answer is the interplay between the atmosphere and the oceans, where heat is being transfered between parts of the Earth system under conditions of flows such as the movement of air and water - what we call winds and ocean currents. There are detectable patterns in the flows of air and water - and some are oscillatory, so the temperature (taken at any one time) may appear to wriggle up and down (when viewed over a period of time). Despite these wobbles, the overall trend of temperature over several decades has been reliably detected. Despite Nigel Lawson's attention to air temperatures, they are probably the least significant in detecting global warming, even though the data shows that baseline air temperatures, averaged over time, are rising. The vast proportion of heat being added to the Earth system is ending up in the oceans :-
    http://www.skepticalscience.com/global-cooling-intermediate.htm
    and the rise in ocean temperatures is consistent :-

    which indicates that circulatory patterns of heat exchange in the oceans have less effect on making temperatures fluctuate than the movement of masses of air in the atmosphere. This is exactly what you would expect from the study of basic physics. If you give only a cursory glance at the recent air temperatures at the surface of the Earth, you could think that temperatures have levelled off in the last decade or so, but taking a longer term view easily shows that global warming continues to be significant :-
    http://data.giss.nasa.gov/gistemp/graphs_v3/
    What is truly astonishing about this data is that the signal shows through the noise - that the trend in global warming is easily evident by eye, despite the wavy shakes from natural variability. For Nigel Lawson's information, the reason why we refer to climate change is to attempt to encompass other evidence in this term besides purely temperature measurements. As the climate changes, rainfall patterns are altering, for example, which is not something that can be expressed in the term global warming. ]

    I have never shied away from controversy, nor — for example, as Chancellor — worried about being unpopular if I believed that what I was saying and doing was in the public interest.

    But I have never in my life experienced the extremes of personal hostility, vituperation and vilification which I — along with other dissenters, of course — have received for my views on global warming and global warming policies.

    For example, according to the Climate Change Secretary, Ed Davey, the global warming dissenters are, without exception, “wilfully ignorant” and in the view of the Prince of Wales we are “headless chickens”. Not that “dissenter” is a term they use. We are regularly referred to as “climate change deniers”, a phrase deliberately designed to echo “Holocaust denier” — as if questioning present policies and forecasts of the future is equivalent to casting malign doubt about a historical fact.

    [ joabbess.com : Climate change science is built on observations : all historical facts. Then, as in any valid science, a theoretical framework is applied to the data to check the theory - to make predictions of future change, and to validate them. It is an historical fact that the theoretical framework for global warming has not been falsified. The Earth system is warming - this cannot be denied. It seems to me that Nigel Lawwon usurps the truth with myth and unsubstantiated rumour, casting himself in the role of doubting dissenter, yet denying the evidence of the data. He therefore self-categorises as a denier, by the stance of denial that he takes. His denial is also an historical fact, but calling him a denier is not a value judgement. It is for each person to ascribe for themselves a moral value to the kind of denial he expresses. ]

    The heir to the throne and the minister are senior public figures, who watch their language. The abuse I received after appearing on the BBC’s Today programme last February was far less restrained. Both the BBC and I received an orchestrated barrage of complaints to the effect that it was an outrage that I was allowed to discuss the issue on the programme at all. And even the Science and Technology Committee of the House of Commons shamefully joined the chorus of those who seek to suppress debate.

    [ joabbess.com : Considering the general apathy of most television viewers, it is therefore quite refreshingly positive that so many people decided to complain about Nigel Lawson being given a platform to express his views about climate change, a subject about which it seems he is unqualified to speak with authority of learning. He may consider the complaints an "orchestrated barrage". Another interpretation could be that the general mood of the audience ran counter to his contributions, and disagreed with the BBC's decisiont to permit him to air his contrarian position, to the point of vexation. A parallel example could be the kind of outrage that could be expressed if Nigel Lawson were to deny that the Earth is approximately spherical, that gravity means that things actually move out to space rather than towards the ground, or that water is generally warmer than ice. He should expect opposition to his opinions if he is denying science. ]

    In fact, despite having written a thoroughly documented book about global warming more than five years ago, which happily became something of a bestseller, and having founded a think tank on the subject — the Global Warming Policy Foundation — the following year, and despite frequently being invited on Today to discuss economic issues, this was the first time I had ever been asked to discuss climate change. I strongly suspect it will also be the last time.

    The BBC received a well-organised deluge of complaints — some of them, inevitably, from those with a vested interest in renewable energy — accusing me, among other things, of being a geriatric retired politician and not a climate scientist, and so wholly unqualified to discuss the issue.

    [ joabbess.com : It is a mark of integrity to put you money where your mouth is, not an indicator on insincerity. It is natural to expect people who accept climate change science to be taking action on carbon dioxide emissions, which includes investment in renewable energy. ]

    Perhaps, in passing, I should address the frequent accusation from those who violently object to any challenge to any aspect of the prevailing climate change doctrine, that the Global Warming Policy Foundation’s non-disclosure of the names of our donors is proof that we are a thoroughly sinister organisation and a front for the fossil fuel industry.

    As I have pointed out on a number of occasions, the Foundation’s Board of Trustees decided, from the outset, that it would neither solicit nor accept any money from the energy industry or from anyone with a significant interest in the energy industry. And to those who are not-regrettably-prepared to accept my word, I would point out that among our trustees are a bishop of the Church of England, a former private secretary to the Queen, and a former head of the Civil Service. Anyone who imagines that we are all engaged in a conspiracy to lie is clearly in an advanced stage of paranoia.

    The reason why we do not reveal the names of our donors, who are private citizens of a philanthropic disposition, is in fact pretty obvious. Were we to do so, they, too, would be likely to be subject to the vilification and abuse I mentioned earlier. And that is something which, understandably, they can do without.

    That said, I must admit I am strongly tempted to agree that, since I am not a climate scientist, I should from now on remain silent on the subject — on the clear understanding, of course, that everyone else plays by the same rules. No more statements by Ed Davey, or indeed any other politician, including Ed Milliband, Lord Deben and Al Gore. Nothing more from the Prince of Wales, or from Lord Stern. What bliss!

    But of course this is not going to happen. Nor should it; for at bottom this is not a scientific issue. That is to say, the issue is not climate change but climate change alarmism, and the hugely damaging policies that are advocated, and in some cases put in place, in its name. And alarmism is a feature not of the physical world, which is what climate scientists study, but of human behaviour; the province, in other words, of economists, historians, sociologists, psychologists and — dare I say it — politicians.

    [ joabbess.com : Au contraire, I would say to Nigel Lawson. At root, climate change is very much a scientific issue. Science defines it, describes it and provides evidence for it. Climate change is an epistemological concern, and an ontological challenge. How we know what we know about climate change is by study of a very large number of results from data collection and other kinds of research. The evidence base is massive. The knowledge expressed in climate change science is empirical - based on observations - which is how we are sure that what we know is assured. There is still scope for uncertainty - will the surface temperatures rise by X plus or minus some Y, owing to the dynamic between the atmosphere, the oceans, the ice cover and the land masses ? The results of the IPCC assessments are that we pretty much know what X is, and we have an improved clarity on a range of values for Y. The more science is done, the clearer these numbers emerge. Knowledge increases as more science is done, which is why the IPCC assessments are making firmer conclusions as time passes. Climate change science does not make value judgements on its results. It concludes that sea levels are rising and will continue to rise; that rainfall patterns are changing and will continue to change; that temperatures are rising and will continue to rise under current economic conditions and the levels of fossil fuel use and land use. Science describes the outcomes of these and other climate changes. It is for us as human beings, with humanity in our hearts, to place a meaning on predicted outcomes such as crop and harvest failures, displacement of peoples, unliveable habitats, loss of plant and animal species, extreme weather. You cannot take the human out of the scientist. Of course scientists will experience alarm at the thought of these outcomes, just as the rest of society will do. The people should not be denied the right to feeling alarm. ]

    And en passant, the problem for dissenting politicians, and indeed for dissenting climate scientists for that matter, who certainly exist, is that dissent can be career-threatening. The advantage of being geriatric is that my career is behind me: there is nothing left to threaten.

    [ joabbess.com : Climate change science is not something you can "dissent" from if you are at all versed in it. For those who question any part of climate change science from inside the community of those who have appropriate knowledge and learning, their position is not one of dissent, but of being unable to assent completely to the conclusions of their peers. They lack a capacity to fully assent to the results of other people's research because their own research indicates otherwise. As responsible members of the science community, they would then put their research conclusions and the research conclusions of others to the test. There is an integrity in this kind of questioning. It is a valid position, as long as the questions are posed in the language of scientific enquiry, and answered with scientific methods. For example, the Berkeley BEST team had questions about the evidence of global warming and set out to verify or falsify the results of others. Their own research led them to become convinced that their peers had been correct in the their conclusions. This is how science comes to consensus. Nigel Lawson should fund research in the field if he wishes to be taken seriously in denying the current consensus in climate change science. Instead of which, he invests in the publication of what appears to be uncorroborated hearsay and emotive politicking. ]

    But to return: the climate changes all the time, in different and unpredictable (certainly unpredicted) ways, and indeed often in different ways in different parts of the world. It always has done and no doubt it always will. The issue is whether that is a cause for alarm — and not just moderate alarm. According to the alarmists it is the greatest threat facing humankind today: far worse than any of the manifold evils we see around the globe which stem from what Pope called “man’s inhumanity to man”.

    [ joabbess.com : Nigel Lawson doesn't need to tell anyone that weather is changeable and that climate changes. They can see it for themselves if they care to study the data. Climate change science has discovered that the current changes in the climate are unprecedented within at least the last 800,000 years. No previous period of rapid climate change in that era has been entirely similar to the changes we are experiencing today. This is definite cause for alarm, high level alarm, and not moderate. If there is a fire, it is natural to sound the alarm. If there is a pandemic, people spread the news. If there is a risk, as human beings, we take collective measures to avoid the threat. This is normal human precautionary behaviour. It is unreasonable for Nigel Lawson to insist that alarm is not an appropriate response to what is patently in the process of happening. ]

    Climate change alarmism is a belief system, and needs to be evaluated as such.

    [ joabbess.com : Belief in gravity, or thinking that protein is good to eat are also belief systems. Everything we accept as normal and true is part of our own belief system. For example, I believe that Nigel Lawson is misguided and has come to the wrong conclusions. The evidence lies before me. Is my opinion to be disregarded because I have a belief that Nigel Lawson is incorrect ? ]

    There is, indeed, an accepted scientific theory which I do not dispute and which, the alarmists claim, justifies their belief and their alarm.

    This is the so-called greenhouse effect: the fact that the earth’s atmosphere contains so-called greenhouse gases (of which water vapour is overwhelmingly the most important, but carbon dioxide is another) which, in effect, trap some of the heat we receive from the sun and prevent it from bouncing back into space.

    Without the greenhouse effect, the planet would be so cold as to be uninhabitable. But, by burning fossil fuels — coal, oil and gas — we are increasing the amount of carbon dioxide in the atmosphere and thus, other things being equal, increasing the earth’s temperature.

    But four questions immediately arise, all of which need to be addressed, coolly and rationally.

    First, other things being equal, how much can increased atmospheric CO2 be expected to warm the earth? (This is known to scientists as climate sensitivity, or sometimes the climate sensitivity of carbon.) This is highly uncertain, not least because clouds have an important role to play, and the science of clouds is little understood. Until recently, the majority opinion among climate scientists had been that clouds greatly amplify the basic greenhouse effect. But there is a significant minority, including some of the most eminent climate scientists, who strongly dispute this.

    [ joabbess.com : Simple gas chemistry and physics that is at least a century old is evidence that carbon dioxide allows sunlight to pass right through to warm the Earth, which then emits infrared light because it has warmed up. When the infrared radiation is emitted, the Earth cools down. Infrared is partially blocked by carbon dioxide, which absorbs it, then re-radiates it, partially back to the Earth, which warms up again. Eventually, the warming radiation will escape the carbon dioxide blanket, but because of this trapping effect, the net result is for more heat to remain in the atmosphere close to the Earth's surface than you would expect. This is the main reason why the temperature of the Earth's surface is warmer than space. As carbon dioxide accumulates in the atmosphere, the warming effect will be enhanced. This is global warming and it is undisputed by the overwhelming majority of scientists. Climate sensitivity, or Equilibrium Climate Sensitivity (ECS) is a calculated measure of the total temperature change that would be experienced (after some time) at the surface of the Earth for a doubling of atmospheric carbon dioxide concentrations compare to the pre-industrial age. The Transient Climate Response (TCR) is a measure of the temperature change that would be experienced in the shorter-term for a doubling of atmospheric carbon dioxide concentrations. The TCR can be easily calculated from basic physics. The shorter-term warming will cause climate change. Some of the changes will act to cool the Earth down from the TCR (negative feedbacks). Some of the changes will act to heat the Earth up from the TCR (positive feedbacks). These are some disagreements about the ECS, such as the net effects from the fertilisation effect of carbon dioxide on plant growth, the net effects of changes in weather and cloud systems, and the net effects of changes in ocean and atmospheric circulation. However, evidence from the deep past (paleoclimatology) is helping to determine the range of temperatures that ECS could be. ]

    Second, are other things equal, anyway? We know that, over millennia, the temperature of the earth has varied a great deal, long before the arrival of fossil fuels. To take only the past thousand years, a thousand years ago we were benefiting from the so-called medieval warm period, when temperatures are thought to have been at least as warm, if not warmer, than they are today. And during the Baroque era we were grimly suffering the cold of the so-called Little Ice Age, when the Thames frequently froze in winter and substantial ice fairs were held on it, which have been immortalised in contemporary prints.

    [ joabbess.com : The Medieval Warming Period (or Medieval Warm Period) was just a blip compared to the current global warming of the last 150 years. And the Little Ice Age was also a minor anomaly, being pretty much confined to the region of Europe, and some expect could have become the Rather Much Longer Icy Period had it not been for the use of fossil fuels, which warmed Europe up again. Burning coal and other fossil fuels releases carbon that would have originally been in the atmosphere in the form of carbon dioxide millions of years ago, that trees and other plants used to grow. Geological evidence shows that surface temperatures at those times were warmer than today. ]

    Third, even if the earth were to warm, so far from this necessarily being a cause for alarm, does it matter? It would, after all, be surprising if the planet were on a happy but precarious temperature knife-edge, from which any change in either direction would be a major disaster. In fact, we know that, if there were to be any future warming (and for the reasons already given, “if” is correct) there would be both benefits and what the economists call disbenefits. I shall discuss later where the balance might lie.

    [ joabbess.com : The evidence from the global warming that we have experienced so far since around 1880 is almost universally limiting in terms of the ability of species of animals and plants to survive. There are tiny gems of positive outcomes, compared to a sand pit of negatives. Yes, of course it matters. The mathematics of chaos with strong perturbations to any system do not permit it to coast on a precarious knife-edge for very long. Sooner or later there will be a major alteration, and the potential for some milder probable outcomes will collapse. ]

    And fourth, to the extent that there is a problem, what should we, calmly and rationally, do about it?

    [ joabbess.com : The most calm and rational thing to do is to compile all the evidence and report on it. Oh yes, we've already done that. It's called the Intergovernmental Panel on Climate Change or IPCC. The concluisons of the compilation of over 100 years of science is that global warming is real, and it's happening now, and that there is a wide range of evidence for climate change, and indicators that it is a major problem, and that we have caused it, through using fossil fuels and changing how we use land. ]

    It is probably best to take the first two questions together.

    According to the temperature records kept by the UK Met Office (and other series are much the same), over the past 150 years (that is, from the very beginnings of the Industrial Revolution), mean global temperature has increased by a little under a degree centigrade — according to the Met Office, 0.8ºC. This has happened in fits and starts, which are not fully understood. To begin with, to the extent that anyone noticed it, it was seen as a welcome and natural recovery from the rigours of the Little Ice Age. But the great bulk of it — 0.5ºC out of the 0.8ºC — occurred during the last quarter of the 20th century. It was then that global warming alarmism was born.

    [ joabbess.com : Nigel Lawson calls it "alarmism". I call it empirical science. And there are many scientific explanations for what he calls "fits and starts", it's just that they're written in research papers, so he will probably never read them, going on his lack of attention to research publications in the past. ]

    But since then, and wholly contrary to the expectations of the overwhelming majority of climate scientists, who confidently predicted that global warming would not merely continue but would accelerate, given the unprecedented growth of global carbon emissions, as China’s coal-based economy has grown by leaps and bounds, there has been no further warming at all. To be precise, the latest report of the Intergovernmental Panel on Climate Change (IPCC), a deeply flawed body whose non-scientist chairman is a committed climate alarmist, reckons that global warming has latterly been occurring at the rate of — wait for it — 0.05ºC per decade, plus or minus 0.1ºC. Their figures, not mine. In other words, the observed rate of warming is less than the margin of error.

    [ joabbess.com : It is not valid for Nigel Lawson to claim that there has been "no further warming at all". Heat accumulation continues to be documented. Where is Nigel Lawson's evidence to support his claim that the IPCC is a "deeply flawed body" ? Or is that another one of his entirely unsubstantiated dismissals of science ? Does he just fudge the facts, gloss over the details, pour scorn on scientists, impugn the academies of science, play with semantics, stir up antipathy, wave his hands and the whole history of science suddenly vanishes in a puff of dismissive smoke ? I doubt it ! Nigel Lawson says "the observed rate of warming is less than the margin of error." This is ridiculous, because temperature is not something that you can add or subtract, like bags of sugar, or baskets of apples, or Pounds Sterling to the Global Warming Policy Foundation's public relations fund. Two degrees Celsius, or Centigrade, is not twice as warm as one degree Celsius. 30 degrees C doesn't indicate twice as much heat as 15 degrees C, or require twice as much heating. The range of figures that Nigel Lawson is quoting, minus 0.05 degrees C plus or minus 0.1 degrees C, that is, somewhere between a cooling of 0.05 degrees C and a warming of 0.15 degrees C, is a calculation of temperature trends averaged over the whole Earth's surface for the last 15 years :-
    http://www.climatechange2013.org/images/uploads/WGIAR5_WGI-12Doc2b_FinalDraft_Chapter09.pdf (Box 9.2)
    It is not surprising that over such a short timescale it might appear that the Earth as experienced a mild cooling effect. In the last 15 years there have been a couple of years far hotter than average, and these spike the calculated trend. For example, 1998 was much hotter than the years before or after it, so if you were just to compare 1998 with 2008, it would look like the Earth is cooling down. But who would be foolish enough to look at just two calendar years of the data record on which to base their argument ? The last 15 years have to be taken in context. In "Climate Change 2013 : The Physical Science Basis", the IPCC report from Working Group 1, in the Summary for Policymakers, page 5, Section B1, the IPCC write :-
    http://www.climatechange2013.org/images/report/WG1AR5_ALL_FINAL.pdf
    "In addition to robust multi-decadal warming, global mean surface temperature exhibits substantial decadal and interannual variability [...] Due to natural variability, trends based on short records are very sensitive to the beginning and end dates and do not in general reflect long-term climate trends. As one example, the rate of warming over the past 15 years (1998–2012; 0.05 [–0.05 to 0.15] °C per decade), which begins with a strong El Niño, is smaller than the rate calculated since 1951 (1951–2012; 0.12 [0.08 to 0.14] °C per decade).” (El Niño is a prominent pattern of winds and ocean currents in the Pacific Ocean with two main states – one that tends to produce a warming effect on the Earth’s surface temperatures, and the other, La Niña, which has a general cooling effect.) ] In other words, in the last fifteen years, the range of rate of change of temperature is calculated to be somewhere between the surface of the planet cooling by 0.05 degrees Centigrade, up to warming by 0.15 degrees Centigrade :-
    http://data.giss.nasa.gov/gistemp/graphs_v3/Fig.C.gif
    http://www.climate4you.com/GlobalTemperatures.htm#Recent%20global%20satellite%20temperature
    However, this calculation of a trend line does not take account of three things. First, in the last decade or so, the variability of individual years could mask a trend, but relative to the last 50 years, everything is clearly hotter on average. Secondly, temperature is not a “discrete” quantity, it is a continuous field of effect, and it is going to have different values depending on location and time. The temperature for any January to December is only going to be an average of averages. If you were to measure the year from March to February instead, the average of averages could look different, because of the natural variability. Thirdly, there are lots of causes for local and regional temperature variability, all concurrent, so it is not until some time after a set of measurements has been taken, and other sets of measurements have been done, that it is possible to determine that a substantial change has taken place. ]

    And that margin of error, it must be said, is implausibly small. After all, calculating mean global temperature from the records of weather stations and maritime observations around the world, of varying quality, is a pretty heroic task in the first place. Not to mention the fact that there is a considerable difference between daytime and night-time temperatures. In any event, to produce a figure accurate to hundredths of a degree is palpably absurd.

    [ joabbess.com : Nigel Lawson could be said to mislead in his explanation of what "a figure accurate to hundredths of a degree" implies. Temperature is measured on an arbitrarily decided scale. To raise the whole of the Earth surface temperatures by 1 degree Celsius requires a lot of extra trapped energy. The surface temperature of the Earth is increasing by the absorption of energy that amounts roughly to 2 trillion Hiroshima atombic bombs since 1998, or 4 Hiroshimas a second. That is not a small number, although it has to be seen in the full context of the energy flows in and out of the Earth system :-
    http://www.skepticalscience.com/4-Hiroshima-bombs-per-second-widget-raise-awareness-global-warming.html
    http://blogs.discovermagazine.com/imageo/2013/12/03/climate-bomb-redux/#.U2tlfaI-hrQ
    Nigel Lawson credits the global temperature monitoring exercise as "heroic", but then berates its quality. However, climate change scientists do already appreciate that there are differences between daytime and nighttime temperatures - it is called the diurnal range. Besides differences between years, it is known that there are also differences between seasons, and latitudes, and climatic zones. Scientists are not claiming an absolute single value for the temperature of the Earth, accurate to within hundredths of a degree - that's why they always give a margin of error. What is astonishing from reviews of the data is something that Nigel Lawson has completely missed. Global warming appears to have fractal resolution - that is - at whatever geographical scale you resolve the data, the trend in most cases appears to be similar. If you take a look at some of the websites offering graphs, for example :-
    http://www.rimfrost.no/
    http://data.giss.nasa.gov/gistemp/station_data/
    the global warming trend is seen to be generally similar when averaged locally, regionally or at the global scale. This is an indicator that the global warming signal is properly being detected, as these trend lines are more or less what you would expect from basic physics and chemistry - the more carbon dioxide in the air, the more heat gets trapped, and the rate of carbon dioxide accumulation in the atmosphere has seen similar trendlines :-
    http://cdiac.esd.ornl.gov/trends/co2/recent_mauna_loa_co2.html ]

    The lessons of the unpredicted 15-year global temperature standstill (or hiatus as the IPCC calls it) are clear. In the first place, the so-called Integrated Assessment Models which the climate science community uses to predict the global temperature increase which is likely to occur over the next 100 years are almost certainly mistaken, in that climate sensitivity is almost certainly significantly less than they once thought, and thus the models exaggerate the likely temperature rise over the next hundred years.

    [ joabbess.com : I repeat : there is no pause. The IPCC are not claiming that global warming has stopped, only that there is an apparent "hiatus" in global surface temperature averages. Some scientists have concluded from their work that Climate Sensitivity is less than once feared. However, Climate Sensitivity is calculated for an immediate, once-only doubling of carbon dioxide in the atmosphere, whereas the reality is that carbon dioxide is continuing to build up in the atmosphere, and if emissions continue unabated, there could be a tripling or quadrupling of carbon dioxide concentrations in the atmosphere, which would mean that you would need to multiply the Climate Sensitivity by 1.5 or 2 to arrive at the final top temperature - higher than previously calculated, regardless of whether the expected Climate Sensitivity were to be less than previously calculated. It is therefore illogical for Nigel Lawson to extrapolate from his understanding that Climate Sensitivity is lower than previously calculated to his conclusion that the final level of global warming will be lower than previously calculated. The more carbon dioxide we emit, the worse it will be. ]

    But the need for a rethink does not stop there. As the noted climate scientist Professor Judith Curry, chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, recently observed in written testimony to the US Senate:
    “Anthropogenic global warming is a proposed theory whose basic mechnism is well understood, but whose magnitude is highly uncertain. The growing evidence that climate models are too sensitive to CO2 has implications for the attribution of late-20th-century warming and projections of 21st-century climate. If the recent warming hiatus is caused by natural variability, then this raises the question as to what extent the warming between 1975 and 2000 can also be explained by natural climate variability.”

    [ joabbess.com : The IPCC reports constitute the world's best attempts to "rethink" Climate Change. Professor Judith Curry, in the quotation given by Nigel Lawson, undervalues a great deal of her colleagues' work by dismissing their valid attribution of Climate Change to the burning of fossil fuels and the change in land use. ]

    It is true that most members of the climate science establishment are reluctant to accept this, and argue that the missing heat has for the time being gone into the (very cold) ocean depths, only to be released later. This is, however, highly conjectural. Assessing the mean global temperature of the ocean depths is — unsurprisingly — even less reliable, by a long way, than the surface temperature record. And in any event most scientists reckon that it will take thousands of years for this “missing heat” to be released to the surface.

    [ joabbess.com : That the oceans are warming is not conjecture - it is a statement based on data. The oceans have a far greater capacity for heat retention than the atmosphere, so yes, it will take a long time for heat in the oceans to re-emerge into the atmosphere. However, the processes that directed heat into the oceans rather than the atmosphere in recent years could easily reverse, and in a short space of time the atmosphere could heat up considerably. In making his arguments, Nigel Lawson omits to consider this eventuality, which lowers considerably the value of his conclusions. ]

    In short, the CO2 effect on the earth’s temperature is probably less than was previously thought, and other things — that is, natural variability and possibly solar influences — are relatively more significant than has hitherto been assumed.

    [ joabbess.com : Nothing about science has changed. The Earth system continues to accumulate heat and respond to that. Carbon dioxide still contributes to the Greenhouse Effect, and extra carbon dioxide in the air will cause further global warming. The Transient Climate Response to carbon dioxide is still apparently linear. The Equilibrium Climate Sensitivity is still calculated to be roughly what it always has been - but that's only for a doubling of atmospheric carbon dioxide. If more methane is emitted as a result of Arctic warming, for example, or the rate of fossil fuel use increases, then the temperature increase of the Earth's surface could be more than previously thought. Natural variability and solar changes are all considered in the IPCC reports, and all calculations and models take account of them. However, the obvious possibility presents itself - that the patterns of natural variability as experienced by the Earth during the last 800,000 years are themseles being changed. If Climate Change is happening so quickly as to affect natural variability, then the outcomes could be much more serious than anticipated. ]

    But let us assume that the global temperature hiatus does, at some point, come to an end, and a modest degree of global warming resumes. How much does this matter?

    The answer must be that it matters very little. There are plainly both advantages and disadvantages from a warmer temperature, and these will vary from region to region depending to some extent on the existing temperature in the region concerned. And it is helpful in this context that the climate scientists believe that the global warming they expect from increased atmospheric CO2 will be greatest in the cold polar regions and least in the warm tropical regions, and will be greater at night than in the day, and greater in winter than in summer. Be that as it may, studies have clearly shown that, overall, the warming that the climate models are now predicting for most of this century (I referred to these models earlier, and will come back to them later) is likely to do more good than harm.

    [ joabbess.com : The claim that warming will "overall [...] do more good than harm” is erroneous, according to Climate Change Science. ]

    Global warming orthodoxy is not merely irrational. It is wicked.

    [ joabbess.com : My conclusions upon reading this lecture are that the evidence suggests that Nigel Lawson's position is ill-informed. He should read the IPCC reports and re-consider. ]

    Amongst the chink-clink of wine glasses at yesterday evening’s Open Cities Green Sky Thinking Max Fordham event, I find myself supping a high ball orange juice with an engineer who does energy retrofits – more precisely – heat retrofits. “Yeah. Drilling holes in Grade I Listed walls for the District Heating pipework is quite nervewracking, as you can imagine. When they said they wanted to put an energy centre deep underneath the building, I asked them, “Where are you going to put the flue ?””

    Our attention turns to heat metering. We discuss cases we know of where people have installed metering underground on new developments and fitted them with Internet gateways and then found that as the rest of the buildings get completed, the meter can no longer speak to the world. The problems of radio-meets-thick-concrete and radio-in-a-steel-cage. We agree that anybody installing a remote wifi type communications system on metering should be obliged in the contract to re-commission it every year.

    And then we move on to shale gas. “The United States of America could become fuel-independent within ten years”, says my correspondent. I fake yawn. It really is tragic how some people believe lies that big. “There’s no way that’s going to happen !”, I assert.

    “Look,” I say, (jumping over the thorny question of Albertan syncrude, which is technically Canadian, not American), “The only reason there’s been strong growth in shale gas production is because there was a huge burst in shale gas drilling, and now it’s been shown to be uneconomic, the boom has busted. Even the Energy Information Administration is not predicting strong growth in shale gas. They’re looking at growth in coalbed methane, after some years. And the Arctic.” “The Arctic ?”, chimes in Party Number 3. “Yes,” I clarify, “Brought to you in association with Canada. Shale gas is a non-starter in Europe. I always think back to the USGS. They estimate that the total resource in the whole of Europe is a whole order of magnitude, that is, ten times smaller than it is in Northern America.” “And I should have thought you couldn’t have the same kind of drilling in Europe because of the population density ?”, chips in Party Number 3. “They’re going to be drilling a lot of empty holes,” I add, “the “sweet spot” problem means they’re only likely to have good production in a few areas. And I’m not a geologist, but there’s the stratigraphy and the kind of shale we have here – it’s just not the same as in the USA.” Parties Number 2 and 3 look vaguely amenable to this line of argument. “And the problems that we think we know about are not the real problems,” I out-on-a-limbed. “The shale gas drillers will probably give up on hydraulic fracturing of low density shale formations, which will appease the environmentalists, but then they will go for drilling coal lenses and seams inside and alongside the shales, where there’s potential for high volumes of free gas just waiting to pop out. And that could cause serious problems if the pressures are high – subsidence, and so on. Even then, I cannot see how production could be very high, and it’s going to take some time for it to come on-stream…” “…about 10 years,” says Party Number 2.

    “Just think about who is going for shale gas in the UK,” I ventured, “Not the big boys. They’ve stood back and let the little guys come in to drill for shale gas. I mean, BP did a bunch of onshore seismic surveys in the 1950s, after which they went drilling offshore in the North Sea, so I think that says it all, really. They know there’s not much gas on land.” There were some raised eyebrows, as if to say, well, perhaps seismic surveys are better these days, but there was agreement that shale gas will come on slowly.

    “I don’t think shale gas can contribute to energy security for at least a decade,” I claimed, “even if there’s anything really there. Shale gas is not going to answer the problems of the loss of nuclear generation, or the problems of gas-fired generation becoming uneconomic because of the strong growth in renewables.” There was a nodding of heads.

    “I think,” I said, “We should forget subsidies. UK plc ought to purchase a couple of CCGTS [Combined Cycle Gas Turbine electricity generation units]. That will guarantee they stay running to load balance the power grid when we need them to. Although the UK’s Capacity Mechanism plan is in line with the European Union’s plans for supporting gas-fired generation, it’s not achieving anything yet.” I added that we needed to continue building as much wind power as possible, as it’s quick to put in place. I quite liked my radical little proposal for energy security, and the people I was talking with did not object.

    There was some discussion about Green Party policy on the ownership of energy utilities, and how energy and transport networks are basically in the hands of the State, but then Party Number 2 said, “What we really need is consistency of policy. We need an Energy Bill that doesn’t get gutted by a change of administration. I might need to vote Conservative, because Labour would mess around with policy.” “I don’t know,” I said, “it’s going to get messed with whoever is in power. All those people at DECC working on the Electricity Market Reform – they all disappeared. Says something, doesn’t it ?”

    I spoke to Parties Number 2 and 3 about my research into the potential for low carbon gas. “Basically, making gas as a kind of energy storage ?”, queried Party Number 2. I agreed, but omitted to tell him about Germany’s Power-to-Gas Strategy. We agreed that it would be at least a decade before much could come of these technologies, so it wouldn’t contribute immediately to energy security. “But then,” I said, “We have to look at the other end of this transition, and how the big gas producers are going to move towards Renewable Gas. They could be making decisions now that make more of the gas they get out of the ground. They have all the know-how to build kit to make use of the carbon dioxide that is often present in sour conventional reserves, and turn it into fuel, by reacting it with Renewable Hydrogen. If they did that, they could be building sustainability into their business models, as they could transition to making Renewable Gas as the Natural Gas runs down.”

    I asked Parties Number 2 and 3 who they thought would be the first movers on Renewable Gas. We agreed that companies such as GE, Siemens, Alstom, the big engineering groups, who are building gas turbines that are tolerant to a mix of gases, are in prime position to develop closed-loop Renewable Gas systems for power generation – recycling the carbon dioxide. But it will probably take the influence of the shareholders of companies like BP, who will be arguing for evidence that BP are not going to go out of business owing to fossil fuel depletion, to roll out Renewable Gas widely. “We’ve all got our pensions invested in them”, admitted Party Number 2, arguing for BP to gain the ability to sustain itself as well as the planet.

  • David MacKay : Heating London

    Posted on May 2nd, 2014 Jo No comments

    I took some notes from remarks made by Professor David MacKay, the UK Government’s Chief Scientific Advisor, yesterday, 1st May 2014, at an event entitled “How Will We Heat London ?”, held by Max Fordhams as part of the Green Sky Thinking, Open City week. I don’t claim to have recorded his words perfectly, but I hope I’ve captured the gist.


    [David MacKay] : [Agreeing with others on the panel - energy] demand reduction is really important. [We have to compensate for the] “rebound effect”, though [where people start spending money on new energy services if they reduce their demand for their current energy services].

    SAP is an inaccurate tool and not suitable for the uses we put it too :-
    http://www.eden.gov.uk/planning-and-development/building-control/building-control-guidance-notes/sap-calculations-explained/
    http://www.dimplex.co.uk/products/renewable_solutions/building_regulations_part_l.htm

    Things seem to be under-performing [for example, Combined Heat and Power and District Heating schemes]. It would be great to have data. A need for engineering expertise to get in.

    I’m not a Chartered Engineer, but I’m able to talk to engineers. I know a kilowatt from a kilowatt hour [ (Laughter from the room) ]. We’ve [squeezed] a number of engineers into DECC [the Department of Energy and Climate Change].

    I’m an advocate of Heat Pumps, but the data [we have received from demonstration projects] didn’t look very good. We hired two engineers and asked them to do the forensic analysis. The heat pumps were fine, but the systems were being wrongly installed or used.

    Now we have a Heat Network team in DECC – led by an engineer. We’ve published a Heat Strategy. I got to write the first three pages and included an exergy graph.

    [I say to colleagues] please don’t confuse electricity with energy – heat is different. We need not just a green fluffy solution, not just roll out CHP [Combined Heat and Power] [without guidance on design and operation].

    Sources of optimism ? Hopefully some of the examples will be available – but they’re not in the shop at the moment.

    For example, the SunUp Heat Battery – works by having a series of chambers of Phase Change Materials, about the size of a fridge that you would use to store heat, made by electricity during the day, for use at night, and meet the demand of one home. [Comment from Paul Clegg, Senior Partner at Feilden Clegg Bradley Studios : I first heard about Phase Change Materials back in the 1940s ? 1950s ? And nothing's come of it yet. ] Why is that a good idea ? Well, if you have a heat pump and a good control system, you can use electricity when it’s cheapest… This is being trialled in 10 homes.

    Micro-CHP – [of those already trialled] definitely some are hopeless, with low temperature and low electricity production they are just glorified boilers with a figleaf of power.

    Maybe Fuel Cells are going to deliver – power at 50% efficiency [of conversion] – maybe we’ll see a Fuel Cell Micro-Combined Heat and Power unit ?

    Maybe there will be hybrid systems – like the combination of a heat pump and a gas boiler – with suitable controls could lop off peaks of demand (both in power and gas).

    We have designed the 2050 Pathways Calculator as a tool in DECC. It was to see how to meet the Carbon Budget. You can use it as an energy security calculator if you want. We have helped China, Korea and others to write their own calculators.

    A lot of people think CHP is green and fluffy as it is decentralised, but if you’re using Natural Gas, that’s still a Fossil Fuel. If you want to run CHP on biomass, you will need laaaaaarge amounts of land. You can’t make it all add up with CHP. You would need many Wales’-worth of bioenergy or similar ways to make it work.

    Maybe we should carry on using boilers and power with low carbon gas – perhaps with electrolysis [A "yay !" from the audience. Well, me, actually]. Hydrogen – the the 2050 Calculator there is no way to put it back into the beginning of the diagram – but it could provide low carbon heat, industry and transport. At the moment we can only put Hydrogen into Transport [in the 2050 Calculator. If we had staff in DECC to do that... It's Open Source, so if any of you would like to volunteer...

    Plan A of DECC was to convert the UK to using lots of electricity [from nuclear power and other low carbon technologies, to move to a low carbon economy], using heat pumps at the consumer end, but there’s a problem in winter [Bill Watts of Max Fordham had already shown a National Grid or Ofgem chart of electricity demand and gas demand over the year, day by day. Electricity demand (in blue) fluctuates a little, but it pretty regular over the year. Gas demand (in red) however, fluctuates a lot, and is perhaps 6 to 10 times larger in winter than in summer.]

    If [you abandon Plan A - "electrification of everything"] and do it the other way, you will need a large amount of Hydrogen, and a large Hydrogen store. Electrolysers are expensive, but we are doing/have done a feasibility study with ITM Power – to show the cost of electrolysers versus the cost of your wind turbines [My comment : but you're going to need your wind turbines to run your electrolysers with their "spare" or "curtailed" kilowatt hours.]

    [David Mackay, in questions from the floor] We can glue together [some elements]. Maybe the coming smart controls will help…can help save a load of energy. PassivSystems – control such things as your return temperature [in your Communal or District Heating]…instead of suing your heat provider [a reference to James Gallagher who has problems with his communal heating system at Parkside SE10], maybe you could use smart controls…

    [Question] Isn’t using smart controls like putting a Pirelli tyre on a Ford Cortina ? Legacy of poor CHP/DH systems…

    [David MacKay in response to the question of insulation] If insulation were enormously expensve, we wouldn’t have to be so enthusastic about it…We need a well-targeted research programme looking at deep retrofitting, instead of letting it all [heat] out.

    [Adrian Gault, Committee on Climate Change] We need an effective Government programme to deliver that. Don’t have it in the Green Deal. We did have it [in the previous programmes of CERT and CESP], but since they were cancelled in favour of the Green Deal, it’s gone off a cliff [levels of insulation installations]. We would like to see an initiative on low cost insulation expanded. The Green Deal is not producing a response.

    [Bill Watts, Max Fordham] Agree that energy efficiency won’t run on its own. But it’s difficult to do. Not talking about automatons/automation. Need a lot of pressure on this.

    [Adrian Gault] Maybe a street-by-street approach…

    [Michael Trousdell, Arup] Maybe a rule like you can’t sell a house unless you’ve had the insulation done…

    [Peter Clegg] … We can do heat recovery – scavenging the heat from power stations, but we must also de-carbonise the energy supply – this is a key part of the jigsaw.

    Re: Policy and Strategy for North Sea Natural Gas Fields Depletion

    Dear Madam / Sir,

    I researching the history of the development of the gas industry in the United Kingdom, and some of the parallel evolution of the industry in the United States of America and mainland Europe.

    In looking at the period of the mid- to late- 1960s, and the British decision to transition from manufactured gas to Natural Gas supplies, I have been able to answer some of my questions, but not all of them, so far.

    From a variety of sources, I have been able to determine that there were contingency plans to provide substitutes for Natural Gas, either to solve technical problems in the grid conversion away from town gas, or to compensate should North Sea Natural Gas production growth be sluggish, or demand growth higher than anticipated.

    Technologies included the enriching of “lean” hydrogen-rich synthesis gas (reformed from a range of light hydrocarbons, by-products of the petroleum refining industry); Synthetic Natural Gas (SNG) and methane-”rich” gas making processes; and simple mixtures of light hydrocarbons with air.

    In the National Archives Cmd/Cmnd/Command document 3438 “Fuel Policy. Presented to Parliament by the Minister of Power Nov 1967″, I found discussion on how North Sea gas fields could best be exploited, and about expected depletion rates, and that this could promote further exploration and discovery.

    In a range of books and papers of the time, I have found some discussion about options to increase imports of Natural Gas, either by the shipping of Liquified Natural Gas (LNG) or by pipeline from The Netherlands.

    Current British policy in respect of Natural Gas supplies appears to rest on “pipeline diplomacy”, ensuring imports through continued co-operation with partner supplier countries and international organisations.

    I remain unclear about what official technological or structural strategy may exist to bridge the gap between depleting North Sea Natural Gas supplies and continued strong demand, in the event of failure of this policy.

    It is clear from my research into early gas field development that depletion is inevitable, and that although some production can be restored with various techniques, that eventually wells become uneconomic, no matter what the size of the original gas field.

    To my mind, it seems unthinkable that the depletion of the North Sea gas fields was unanticipated, and yet I have yet to find comprehensive policy statements that cover this eventuality and answer its needs.

    Under the Freedom of Information Act (2000), I am requesting information to answer the following questions :-

    1.   At the time of European exploration for Natural Gas in the period 1948 to 1965, and the British conversion from manufactured gas to Natural Gas, in the period 1966 to 1977, what was HM Government’s policy to compensate for the eventual depletion of the North Sea gas fields ?

    2.   What negotiations and agreements were made between HM Government and the nationalised gas industry between 1948 and 1986; and between HM Government and the privatised gas industry between 1986 and today regarding the projections of decline in gas production from the UK Continental Shelf, and any compensating strategy, such as the development of unconventional gas resources, such as shale gas ?

    3.   Is there any policy or strategy to restore the SNG (Synthetic Natural Gas) production capacity of the UK in the event of a longstanding crisis emerging, for example from a sharp rise in imported Natural Gas costs or geopolitical upheaval ?

    4.   Has HM Government any plan to acquire the Intellectual Property rights to SNG production technology, whether from British Gas/Centrica or any other private enterprise, especially for the slagging version of the Lurgi gasifier technology ?

    5.   Has HM Government any stated policy intention to launch new research and development into, or pilot demonstrations of, SNG ?

    6.   Does HM Government have any clearly-defined policy on the production and use of manufactured gas of any type ? If so, please can I know references for the documents ?

    7.   Does HM Government anticipate that manufactured gas production could need to increase in order to support the production of synthetic liquid vehicle fuels; and if so, which technologies are to be considered ?

    Thank you for your attention to my request for information.

    Regards,

    jo.

  • Peak Oil : Kitchen Burlesque

    Posted on March 17th, 2014 Jo No comments

    An engineering buddy and I find ourselves in my kitchen, reading out loud from Jeremy Leggett’s 2013 book “The Energy of Nations : Risk Blindness and the Road to Renaissance”. The main topic of the work, I feel, is the failure of the energy sector and the political elites to develop a realistic plan for the future, and their blinkered adherence to clever arguments taken from failing and cracked narratives – such as the belief that unconventional fossil fuels, such as tar sands, can make up for declining conventional oil and gas production. It’s also about compromise of the highest order in the most influential ranks. The vignettes recalling conversations with the high and mighty are pure comedy.

    “It’s very dramatic…”

    “You can imagine it being taken to the West End theatres…”

    “We should ask Ben Elton to take a look – adapt it for the stage…”

    “It should really have costumes. Period costumes…Racy costumes…”

    “Vaudeville ?”

    “No…burlesque ! Imagine the ex-CEO of BP, John Browne, in a frou-frou tutu, slipping a lacy silk strap from his shoulder…What a Lord !”

    “Do you think Jeremy Leggett would look good in a bodice ?”

  • On Having to Start Somewhere

    Posted on March 15th, 2014 Jo No comments

    In the last few weeks I have heard a lot of noble but futile hopes on the subject of carbon dioxide emissions control.

    People always seem to want to project too far into the future and lay out their wonder solution – something that is just too advanced enough to be attainable through any of the means we currently have at our disposal. It is impossible to imagine how the gulf can be bridged between the configuration of things today and their chosen future solutions.

    Naive civil servants strongly believe in a massive programme of new nuclear power. Head-in-the-clouds climate change consultants and engineers who should know otherwise believe in widespread Carbon Capture and Storage or CCS. MBA students believe in carbon pricing, with carbon trading, or a flat carbon tax. Social engineers believe in significant reductions in energy intensity and energy consumer behaviour change, and economists believe in huge cost reductions for all forms of renewable electricity generation.

    To make any progress at all, we need to start where we are. Our economic system has strong emissions-dependent components that can easily be projected to fight off contenders. The thing is, you can’t take a whole layer of bricks out of a Jenga stack without severe degradation of its stability. You need to work with the stack as it is, with all the balances and stresses that already exist. It is too hard to attempt to change everything at once, and the glowing ethereal light of the future is just too ghostly to snatch a hold of without a firm grasp on an appropriate practical rather than spiritual guide.

    Here’s part of an email exchange in which I strive for pragmatism in the face of what I perceive as a lack of realism.


    To: Jo

    I read your article with interest. You have focused on energy, whereas I
    tend to focus on total resource. CCS does make sense and should be pushed
    forward with real drive as existing power stations can be cleaned up with it
    and enjoy a much longer life. Establishing CCS is cheaper than building new
    nuclear and uses far less resources. Furthermore, CCS should be used on new
    gas and biomass plants in the future.

    What we are lacking at the moment is any politician with vision in this
    space. Through a combination of boiler upgrades, insulation, appliance
    upgrades and behaviour change, it is straight forward to halve domestic
    energy use. Businesses are starting to make real headway with energy
    savings. We can therefore maintain a current total energy demand for the
    foreseeable future.

    To service this demand, we should continue to eke out every last effective
    joule from the current generating stock by adding cleansing kit to the dirty
    performers. While this is being done, we can continue to develop renewable
    energy and localised systems which can help to reduce the base load
    requirement even further.

    From an operational perspective, CCS has stagnated over the last 8 years, so
    a test plant needs to be put in place as soon as possible.

    The biggest issue for me is that, through political meddling and the
    unintended consequences of ill-thought out subsidies, the market has been
    skewed in such a way that the probability of a black-out next year is very
    high indeed.

    Green gas is invisible in many people’s thinking, but the latest House of
    Lords Report highlighted its potential.

    Vested interests are winning hands down in the stand-off with the big
    picture!


    From: Jo

    What is the title of the House of Lords report to which you refer ?

    Sadly, I am old enough to remember Carbon Capture and Storage (CCS)
    the first time the notion went around the block, so I’d say that
    progress has been thin for 30 years rather than 8.

    Original proposals for CCS included sequestration at the bottom of the
    ocean, which have only recently been ruled out as the study of global
    ocean circulation has discovered more complex looping of deep and
    shallower waters that originally modelled – the carbon dioxide would
    come back up to the surface waters eventually…

    The only way, I believe, that CCS can be made to work is by creating a
    value stream from the actual carbon dioxide, and I don’t mean Enhanced
    Oil Recovery (EOR).

    And I also definitely do not mean carbon dioxide emissions pricing,
    taxation or credit trading. The forces against an
    investment-influencing carbon price are strong, if you analyse the
    games going on in the various economic system components. I do not
    believe that a strong carbon price can be asserted when major economic
    components are locked into carbon – such as the major energy producers
    and suppliers, and some parts of industry, and transport.

    Also, carbon pricing is designed to be cost-efficient, as markets will
    always find the lowest marginal pricing for any externality in fines
    or charges – which is essentially what carbon dioxide emissions are.
    The EU Emissions Trading Scheme was bound to deliver a low carbon
    price – that’s exactly what the economists predicted in modelling
    carbon pricing.

    I cannot see that a carbon price could be imposed that was more than
    5% of the base commodity trade price. At those levels, the carbon
    price is just an irritation to pass on to end consumers.

    The main problem is that charging for emissions does not alter
    investment decisions. Just like fines for pollution do not change the
    risks for future pollution. I think that we should stop believing in
    negative charging and start backing positive investment in the energy
    transition.

    You write “You have focused on energy, whereas I tend to focus on
    total resource.” I assume you mean the infrastructure and trading
    systems. My understanding leads me to expect that in the current
    continuing economic stress, solutions to the energy crisis will indeed
    need to re-use existing plant and infrastructure, which is why I
    think that Renewable Gas is a viable option for decarbonising total
    energy supply – it slots right in to substitute for Natural Gas.

    My way to “eke out every last effective joule from the current
    generating stock” is to clean up the fuel, rather than battle
    thermodynamics and capture the carbon dioxide that comes out the back
    end. Although I also recommend carbon recycling to reduce the need for
    input feedstock.

    I completely agree that energy efficiency – cutting energy demand
    through insulation and so on – is essential. But there needs to be a
    fundamental change in the way that profits are made in the energy
    sector before this will happen in a significant way. Currently it
    remains in the best interests of energy production and supply
    companies to produce and supply as much energy as they can, as they
    have a duty to their shareholders to return a profit through high
    sales of their primary products.

    “Vested interests” have every right under legally-binding trade
    agreements to maximise their profits through the highest possible
    sales in a market that is virtually a monopoly. I don’t think this can
    be challenged, not even by climate change science. I think the way
    forward is to change the commodities upon which the energy sector
    thrives. If products from the energy sector include insulation and
    other kinds of efficiency, and if the energy sector companies can
    continue to make sales of these products, then they can reasonably be
    expected to sell less energy. I’m suggesting that energy reduction
    services need to have a lease component.

    Although Alistair Buchanan formerly of Ofgem is right about the
    electricity generation margins slipping really low in the next few
    winters, there are STOR contracts that National Grid have been working
    on, which should keep the lights on, unless Russia turn off the gas
    taps, which is something nobody can do anything much about – not BP,
    nor our diplomatic corps, the GECF (the gas OPEC), nor the WTO.


  • The General Lightness of Carbon Pricing

    Posted on February 27th, 2014 Jo 1 comment

    I was at a very interesting meeting this morning, entitled “Next Steps for Carbon Capture and Storage in the UK”, hosted by the Westminster Energy, Environment and Transport Forum :-

    http://www.westminsterforumprojects.co.uk/forums/event.php?eid=713
    http://www.westminsterforumprojects.co.uk/forums/agenda/CCS-2014-agenda.pdf

    During the proceedings, there were liberal doses of hints at that the Chancellor of the Exchequer is about to freeze the Carbon Price Floor – the central functioning carbon pricing policy in the UK (since the EU Emissions Trading Scheme “isn’t working”).

    All of the more expensive low carbon energy technologies rely on a progressively heavier price for carbon emissions to make their solutions more attractive.

    Where does this leave the prospects for Carbon Capture and Storage in the 2030s ? Initial technology-launching subsidies will have been dropped, and the Contracts for Difference will have been ground down into obscurity. So how will CCS keep afloat ? It’s always going to remain more expensive than other technology options to prevent atmospheric carbon dioxide emissions, so it needs some prop.

    What CCS needs is some Added Value. It will come partly from EOR – Enhanced Oil Recovery, as pumping carbon dioxide down depleting oil and gas fields will help stimulate a few percent of extra production.

    But what will really make the difference is using carbon dioxide to make new fuel. That’s the wonder of Renewable Gas – it will be able to provide a valued product for capturing carbon dioxide.

    This wasn’t talked about this morning. The paradigm is still “filter out the CO2 and flush it down a hole”. But it won’t stay that way forever. Sooner or later, somebody’s going to start mining carbon dioxide from CCS projects to make new chemicals and gas fuels. Then, who cares if there’s negative charging for emissions ? Or at what price ? The return on investment in carbon capture will simply bypass assumptions about needing to create a carbon market or set a carbon tax.

    Here is further email exchange with Professor Richard Sears, following on from a previous web log post.


    From: Richard A. Sears

    Subject: Question from your TED talk

    Jo,

    I was looking back over older emails and saw that I had never responded to your note. It arrived as I was headed to MIT to teach for a week and then it got lost. Sorry about that.

    Some interesting questions. I don’t know anybody working specifically on wind power to gas options. At one time Shell had a project in Iceland using geothermal to make hydrogen. Don’t know what its status is but if you search on hydrogen and Iceland on the Shell website I’m sure there’s something. If the Germans have power to gas as a real policy option I’d poke around the web for information on who their research partners are for this.

    Here are a couple of high level thoughts. Not to discourage you because real progress comes from asking new questions, but there are some physical fundamentals that are important.

    Direct air capture of anything using current technology is prohibitively expensive to do at scale for energy. More energy will be expended in capture and synthesis than the fuels would yield.

    Gaseous fuels are problematic on their own. Gas doesn’t travel well and is difficult to contain at high energy densities as that means compressing or liquefying it. That doesn’t make anything impossible, but it raises many questions about infrastructure and energy balance. If we take the energy content of a barrel of oil as 1.0, then a barrel of liquefied natural gas is about 0.6, compressed natural gas which is typically at about 3600psi is around 0.3, and a barrel (as a measure of volume equal to 42 US gallons) of natural gas at room temperature and pressure is about 0.0015 (+/-). Also there’s a real challenge in storing and transporting gasses as fuel at scale, particularly motor fuel to replace gasoline and diesel.

    While there is some spare wind power potential that doesn’t get utilized because of how the grid must be managed, I expect it is a modest amount of energy compared to what we use today in liquid fuels. I think what that means is that while possible, it’s more likely to happen in niche local markets and applications rather than at national or global scales.

    If you haven’t seen it, a nice reference on the potential of various forms of sustainable energy is available free and online here. http://www.withouthotair.com/

    Hope some of this helps.

    Dear Richard,

    Many thanks for getting back to me. Responses are nice – even if they
    are months late. As they say – better late than never, although with
    climate change, late action will definitely be unwise, according to an
    increasing number of people.

    I have indeed seen the website, and bought and spilled coffee on the
    book of Professor David MacKay’s “Sustainable Energy Without The Hot
    Air” project. It is legendary. However, I have checked and he has only
    covered alternative gas in a couple of paragraphs – in notes. By
    contrast, he spent a long chapter discussing how to filter uranium out
    of seawater and other nuclear pursuits.

    Yet as a colleague of mine, who knows David better than I do, said to
    me this morning, his fascination with nuclear power is rather naive,
    and his belief in the success of Generation III and Generation IV
    lacks evidence. Plus, if we get several large carbon dioxide
    sequestration projects working in the UK – Carbon Capture and Storage
    (CCS) – such as the Drax pipeline (which other companies will also
    join) and the Shell Peterhead demonstration, announced today, then we
    won’t need new nuclear power to meet our 4th Carbon Budget – and maybe
    not even the 5th, either (to be negotiated in 2016, I hear) :-

    http://www.heraldscotland.com/politics/referendum-news/peterhead-confirmed-for-carbon-capture-sitebut-its-not-a-bribe-says-ed-dave.1393232825

    We don’t need to bury this carbon, however; we just need to recycle
    it. And the number of ways to make Renewable Hydrogen, and
    energy-efficiently methanate carbon monoxide and carbon dioxide with
    hydrogen, is increasing. People are already making calculations on how
    much “curtailed” or spare wind power is likely to be available for
    making gas in 10 years’ time, and if solar power in the UK is
    cranked/ramped up, then there will be lots of juicy cost-free power
    ours for the taking – especially during summer nights.

    Direct Air Capture of carbon dioxide is a nonsensical proposition.
    Besides being wrong in terms of the arrow of entropy, it also has the
    knock-on effect of causing carbon dioxide to come back out of the
    ocean to re-equilibrate. I recently read a paper by climate scientists
    that estimated that whatever carbon dioxide you take out of the air,
    you will need to do almost all of it again.

    Instead of uranium, we should be harvesting carbon dioxide from the
    oceans, and using it to make gaseous and liquid fuels.

    Gaseous fuels and electricity complement each other very well -
    particularly in storage and grid balancing terms – there are many
    provisions for the twins of gas and power in standards, laws, policies
    and elsewhere. Regardless of the limitations of gas, there is a huge
    infrastructure already in place that can store, pipe and use it, plus
    it is multi-functional – you can make power, heat, other fuels and
    chemicals from gas. In addition, you can make gas from a range of
    resources and feedstocks and processing streams – the key quartet of
    chemical gas species keep turning up : hydrogen, methane, carbon
    monoxide and carbon dioxide – whether you are looking at the exhaust
    from combustion, Natural Gas, industrial furnace producer gas,
    biological decomposition, just about everywhere – the same four gases.

    Energy transition must include large amounts of renewable electricity
    - because wind and solar power are quick to build yet long nuclear
    power lead times might get extended in poor economic conditions. The
    sun does not always shine and the wind does not always blow (and the
    tide is not always in high flux). Since demand profiles will never be
    able to match supply profiles exactly, there will always be spare
    power capacity that grids cannot use. So Power to Gas becomes the
    optimal solution. At least until there are ways to produce Renewable
    Hydrogen at plants that use process heat from other parts of the
    Renewable Gas toolkit. So the aims are to recycle carbon dioxide from
    gas combustion to make more gas, and recycle gas production process
    heat to make hydrogen to use in the gas production process, and make
    the whole lot as thermally balanced as possible. Yes. We can do that.
    Lower the inputs of fresh carbon of any form, and lower the energy
    requirements to make manufactured gas.

    I met somebody working with Jacobs who was involved in the Carbon
    Recycling project in Iceland. Intriguing, but an order of magnitude
    smaller than I think is possible.

    ITM Power in the UK are doing a Hydrogen-to-gas-grid and methanation
    project in Germany with one of the regions. They have done several
    projects with Kiwa and Shell on gas options in Europe. I know of the
    existence of feasibility reports on the production of synthetic
    methane, but I have not had the opportunity to read them yet…

    I feel quite encouraged that Renewable Gas is already happening. It’s
    a bit patchy, but it’s inevitable, because the narrative of
    unconventional fossil fuels has many flaws. I have been looking at
    issues with reserves growth and unconventionals are not really
    commensurate with conventional resources. There may be a lot of shale
    gas in the ground, but getting it out could be a long process, so
    production volumes might never be very good. In the USA you’ve had
    lots of shale gas – but that’s only been supported by massive drilling
    programmes – is this sustainable ?

    BP have just finished building lots of dollars of kit at Whiting to
    process sour Natural Gas. If they had installed Renewable Gas kit
    instead of the usual acid gas and sulfur processing, they could have
    been preparing for the future. As I understand it, it is possible to
    methanate carbon dioxide without first removing it from the rest of
    the gas it comes in – so methanating sour gas to uprate it is a viable
    option as far as I can see. The hydrogen sulfide would still need to
    be washed out, but the carbon dioxide needn’t be wasted – it can be
    made part of the fuel. And when the sour gas eventually thins out,
    those now methanating sour gas can instead start manufacturing gas
    from low carbon emissions feedstocks and recycled carbon.

    I’m thinking very big.

  • In Confab : Paul Elsner

    Posted on January 23rd, 2014 Jo No comments

    Dr Paul Elsner of Birkbeck College at the University of London gave up some of his valuable time for me today at his little bijou garret-style office in Bloomsbury in Central London, with an excellent, redeeming view of the British Telecom Tower. Leader of the Energy and Climate Change module on Birkbeck’s Climate Change Management programme, he offered me tea and topical information on Renewable Energy, and some advice on discipline in authorship.

    He unpacked the recent whirlwind of optimism surrounding the exploitation of Shale Gas and Shale Oil, and how Climate Change policy is perhaps taking a step back. He said that we have to accept that this is the way the world is at the moment.

    I indicated that I don’t have much confidence in the “Shale Bubble”. I consider it mostly as a public relations exercise – and that there are special conditions in the United States of America where all this propaganda comes from. I said that there are several factors that mean the progress with low carbon fuels continues to be essential, and that Renewable Gas is likely to be key.

    1. First of all, the major energy companies, the oil and gas companies, are not in a healthy financial state to make huge investment. For example, BP has just had the legal ruling that there will be no limit to the amount of compensation claims they will have to face over the Deepwater Horizon disaster. Royal Dutch Shell meanwhile has just had a serious quarterly profit warning – and if that is mostly due to constrained sales (“Peak Oil Demand”) because of economic collapse, that doesn’t help them with the kind of aggressive “discovery” they need to continue with to keep up their Reserves to Production ratio (the amount of proven resources they have on their books). These are not the only problems being faced in the industry. This problem with future anticipated capitalisation means that Big Oil and Gas cannot possibly look at major transitions into Renewable Electricity, so it would be pointless to ask, or try to construct a Carbon Market to force it to happen.

    2. Secondly, despite claims of large reserves of Shale Gas and Shale Oil, ripe for the exploitation of, even major bodies are not anticipating that Peak Oil and Peak Natural Gas will be delayed by many years by the “Shale Gale”. The reservoir characteristics of unconventional fossil fuel fields do not mature in the same way as conventional ones. This means that depletion scenarios for fossil fuels are still as relevant to consider as the decades prior to horizontal drilling and hydraulic fracturing (“fracking”).

    3. Thirdly, the reservoir characteristics of conventional fossil fuel fields yet to exploit, especially in terms of chemical composition, are drifting towards increasingly “sour” conditions – with sigificant levels of hydrogen sulfide and carbon dioxide in them. The sulphur must be removed for a variety of reasons, but the carbon dioxide remains an issue. The answer until recently from policy people would have been Carbon Capture and Storage or CCS. Carbon dioxide should be washed from acid Natural Gas and sequestered under the ocean in salt caverns that previously held fossil hydrocarbons. It was hoped that Carbon Markets and other forms of carbon pricing would have assisted with the payment for CCS. However, recently there has been reduced confidence that this will be significant.

    Renewable Gas is an answer to all three of these issues. It can easily be pursued by the big players in the current energy provision system, with far less investment than wholesale change would demand. It can address concerns of gas resource depletion at a global scale, the onset of which could occur within 20 to 25 years. And it can be deployed to bring poor conventional fossil fuels into consideration for exploitation in the current time – answering regional gas resource depletion.

    Outside, daffodils were blooming in Tavistock Square. In January, yes. The “freaky” weather continues…

  • But Uh-Oh – Those Summer Nights

    Posted on January 20th, 2014 Jo No comments

    A normal, everyday Monday morning at Energy Geek Central. Yes, this is a normal conversation for me to take part in on a Monday morning. Energy geekery at breakfast. Perfect.

    Nuclear Flower Power

    This whole UK Government nuclear power programme plan is ridiculous ! 75 gigawatts (GW) of Generation III nuclear fission reactors ? What are they thinking ? Britain would need to rapidly ramp up its construction capabilities, and that’s not going to happen, even with the help of the Chinese. (And the Americans are not going to take too kindly to the idea of China getting strongly involved with British energy). And then, we’d need to secure almost a quarter of the world’s remaining reserves of uranium, which hasn’t actually been dug up yet. And to cap it all, we’d need to have 10 more geological disposal repositories for the resulting radioactive spent fuel, and we haven’t even managed to negotiate one yet. That is, unless we can burn a good part of that spent fuel in Generation IV nuclear fission reactors – which haven’t even been properly demonstrated yet ! Talk about unconscionable risk !

    Baseload Should Be History By Now, But…

    Whatever the technological capability for nuclear power plants to “load follow” and reduce their output in response to a chance in electricity demand, Generation III reactors would not be run as anything except “baseload” – constantly on, and constantly producing a constant amount of power – although they might turn them off in summer for maintenance. You see, the cost of a Generation III reactor and generation kit is in the initial build – so their investors are not going to permit them to run them at low load factors – even if they could.

    There are risks to running a nuclear power plant at partial load – mostly to do with potential damage to the actual electricity generation equipment. But what are the technology risks that Hinkley Point C gets built, and all that capital is committed, and then it only runs for a couple of years until all that high burn up fuel crumbles and the reactors start leaking plutonium and they have to shut it down permanently ? Who can guarantee it’s a sound bet ?

    If they actually work, running Generation III reactors at constant output as “baseload” will also completely mess with the power market. In all of the scenarios, high nuclear, high non-nuclear, or high fossil fuels with Carbon Capture and Storage (CCS), there will always need to be some renewables in the mix. In all probability this will be rapidly deployed, highly technologically advanced solar power photovoltaics (PV). The amount of solar power that will be generated will be high in summer, but since you have a significant change in energy demand between summer and winter, you’re going to have a massive excess of electricity generation in summer if you add nuclear baseload to solar. Relative to the demand for energy, you’re going to get more Renewable Energy excess in summer and under-supply in winter (even though you get more offshore wind in winter), so it’s critical how you mix those two into your scenario.

    The UK Government’s maximum 75 GW nuclear scenario comprises 55 GW Generation III and 20 GW Generation IV. They could have said 40 GW Gen III to feed Gen IV – the spent fuel from Gen III is needed to kick off Gen IV. Although, if LFTR took off, if they had enough fluoride materials there could be a Thorium way into Gen IV… but this is all so technical, no MP [ Member of Parliament ] is going to get their head round this before 2050.

    The UK Government are saying that 16 GW of nuclear by 2030 should be seen as a first tranche, and that it could double or triple by 2040 – that’s one heck of a deployment rate ! If they think they can get 16 GW by 2030 – then triple that by 10 years later ? It’s not going to happen. And even 30 GW would be horrific. But it’s probably more plausible – if they can get 16 GW by 2030, they can arguably get double that by 2040.

    As a rule of thumb, you would need around 10 tonnes of fissionable fuel to kickstart a Gen IV reactor. They’ve got 106 tonnes of Plutonium, plus 3 or 4 tonnes they recently acquired – from France or Germany (I forget which). So they could start 11 GW of Gen IV – possibly the PRISM – the Hitachi thing – sodium-cooled. They’ve been trying them since the Year Dot – these Fast Reactors – the Breeders – Dounreay. People are expressing more confidence in them now – “Pandora’s Promise” hangs around the narrative that the Clinton administration stopped research into Fast Reactors – Oak Ridge couldn’t be commercial. Throwing sodium around a core 80 times hotter than current core heats – you can’t throw water at it easily. You need something that can carry more heat out. It’s a high technological risk. But then get some French notable nuclear person saying Gen IV technologies – “they’re on the way and they can be done”.

    Radioactive Waste Disposal Woes

    The point being is – if you’re commissioning 30 GW of Gen III in the belief that Gen IV will be developed – then you are setting yourself up to be a hostage to technological fortune. That is a real ethical consideration. Because if you can’t burn the waste fuel from Gen III, you’re left with up to 10 radioactive waste repositories required when you can’t even get one at the moment. The default position is that radioactive spent nuclear fuel will be left at the power stations where they’re created. Typically, nuclear power plants are built on the coast as they need a lot of cooling water. If you are going for 30 GW you will need a load of new sites – possibly somewhere round the South East of England. This is where climate change comes in – rising sea levels, increased storm surge, dissolving, sinking, washed-away beaches, more extreme storms [...] The default spent fuel scenario with numerous coastal decommissioned sites with radioactive interim stores which contain nearly half the current legacy radioactive waste [...]

    Based on the figures from the new Greenpeace report, I calculate that the added radioactive waste and radioactive spent fuel arisings from a programme of 16 GW of nuclear new build would be 244 million Terabequerel (TBq), compared to the legacy level of 87 million TBq.

    The Nuclear Decommissioning Authority (NDA) are due to publish their Radioactive Waste Inventory and their Report on Radioactive Materials not in the Waste Inventory at the end of January 2014. We need to keep a watch out for that, because they may have adapted their anticipated Minimum and Maxmium Derived Inventory.

    Politics Is Living In The Past

    What you hear from politicians is they’re still talking about “baseload”, as if they’ve just found the Holy Grail of Energy Policy. And failed nuclear power. Then tidal. And barrages. This is all in the past. Stuff they’ve either read – in an article in a magazine at the dentist’s surgery waiting room, and they think, alright I’ll use that in a TV programme I’ve been invited to speak on, like Question Time. I think that perhaps, to change the direction of the argument, we might need to rubbish their contribution. A technological society needs to be talking about gasification, catalysis. If you regard yourselves as educated, and have a technological society – your way of living in the future is not only in manufacturing but also ideas – you need to be talking about this not that : low carbon gas fuels, not nuclear power. Ministers and senior civil servants probably suffer from poor briefing – or no briefing. They are relying on what is literally hearsay – informal discussions, or journalists effectively representing industrial interests. Newspapers are full of rubbish and it circulates, like gyres in the oceans. Just circulates around and around – full of rubbish.

    I think part of the problem is that the politicians and chief civil servants and ministers are briefed by the “Old Guard” – very often the ex-nuclear power industry guard. They still believe in big construction projects, with long lead times and massive capital investment, whereas Renewable Electricity is racing ahead, piecemeal, and private investors are desperate to get their money into wind power and solar power because the returns are almost immediate and risk-free.

    Together in Electric Dreams

    Question : Why are the UK Government ploughing on with plans for so much nuclear power ?

    1. They believe that a lot of transport and heat can be made to go electric.
    2. They think they can use spent nuclear fuel in new reactors.
    3. They think it will be cheaper than everything else.
    4. They say it’s vital for UK Energy Security – for emissions reductions, for cost, and for baseload. The big three – always the stated aim of energy policy, and they think nuclear ticks all those three boxes. But it doesn’t.

    What they’ll say is, yes, you have to import uranium, but you’ve got a 4 year stock. Any war you’re going to get yourselves involved in you can probably resolve in 4 days, or 4 weeks. If you go for a very high nuclear scenario, you would be taking quite a big share of the global resource of uranium. There’s 2,600 TWh of nuclear being produced globally. And global final energy demand is around 100,000 TWh – so nuclear power currently produces around 2.6% of global energy supply. At current rates of nuclear generation, according to the World Nuclear Association, you’ve got around 80 years of proven reserves and probably a bit more. Let’s say you double nuclear output by 2050 or 2040 – but in the same time you might just have enough uranium – and then find a bit more. But global energy demand rises significantly as well – so nuclear will still only provide around 3% of global energy demand. That’s not a climate solution – it’s just an energy distraction. All this guff about fusion. Well.

    Cornering The Market In Undug Uranium

    A 75 GW programme would produce at baseload 590 TWh a year – divide by 2,600 – is about 23% of proven global uranium reserves. You’re having to import, regardless of what other countries are doing, you’re trying to corner the market – roughly a quarter. Not even a quarter of the market – a quarter of all known reserves – it’s not all been produced yet. It’s still in the ground. So could you be sure that you could actually run these power stations if you build them ? Without global domination of the New British Empire [...]. The security issues alone – defending coastal targets from a tweeb with a desire to blow them up. 50 years down the line they’re full of radioactive spent fuel that won’t have a repository to go to – we don’t want one here – and how much is it going to cost ?

    My view is that offshore wind will be a major contributor in a high or 100% Renewable Electricity scenario by 2050 or 2060. Maybe 180 GW, that will also be around 600 TWh a year – comparable to that maximum nuclear programme. DECC’s final energy demand 2050 – several scenarios – final energy demand from 6 scenarios came out as between roughly 1,500 TWh a year and the maximum 2,500 TWh. Broadly speaking, if you’re trying to do that just with Renewable Electricity, you begin to struggle quite honestly, unless you’re doing over 600 TWh of offshore wind, and even then you need a fair amount of heat pump stuff which I’m not sure will come through. The good news is that solar might – because of the cost and technology breakthroughs. That brings with it a problem – because you’re delivering a lot of that energy in summer. The other point – David MacKay would say – in his book his estimate was 150 TWh from solar by 2050, on the grounds that that’s where you south-facing roofs are – you need to use higher efficiency triple junction cells with more than 40% efficiency and this would be too expensive for a rollout which would double or triple that 150 TWh – that would be too costly – because those cells are too costly. But with this new stuff, you might get that. Not only the cost goes down, but the coverage goes down. Not doing solar across swathes of countryside. There have always been two issues with solar power – cost and where it’s being deployed.

    Uh-Oh, Summer Days. Uh-Oh, Summer Nights

    With the solar-wind headline, summer days and summer nights are an issue.

    With the nuclear headline, 2040 – they would have up to 50 GW, and that would need to run at somewhere between 75% and 95% capacity – to protect the investment and electric generation turbines.

    It will be interesting to provide some figures – this is how much over-capacity you’re likely to get with this amount of offshore wind. But if you have this amount of nuclear power, you’ll get this amount [...]

    Energy demand is strongly variable with season. We have to consider not just power, but heat – you need to get that energy out in winter – up to 4 times as much during peak in winter evenings. How are you going to do that ? You need gas – or you need extensive Combined Heat and Power (CHP) (which needs gas). Or you need an unimaginable deployment of domestic heat pumps. Air source heat pumps won’t work at the time you need them most. Ground source heat pumps would require the digging up of Britain – and you can’t do that in most urban settings.

    District Heat Fields

    The other way to get heat out to everyone in a low carbon world – apart from low carbon gas – is having a field-based ground source heat pump scheme – just dig up a field next to a city – and just put in pipes and boreholes in a field. You’re not disturbing anybody. You could even grow crops on it next season. Low cost and large scale – but would need a District Heating (DH) network. There are one or two heat pump schemes around the world. Not sure if they are used for cooling in summer or heat extraction in the winter. The other thing is hot water underground. Put in an extra pipe in the normal channels to domestic dwellings. Any excess heat from power generation or electrolysis or whatever is put down this loop and heats the sub-ground. Because heat travels about 1 metre a month in soil, that heat should be retained for winter. A ground source heat sink. Geothermal energy could come through – they’re doing a scheme in Manchester. If there’s a nearby heat district network – it makes it easier. Just want to tee it into the nearest DH system. The urban heat demand is 150 TWh a year. You might be able to put DH out to suburban areas as well. There are 9 million gas-connected suburban homes – another about 150 TWh there as well – or a bit more maybe. Might get to dispose of 300 TWh in heat through DH. The Green Deal insulation gains might not be what is claimed – and condensing gas boiler efficiencies are not that great – which feeds into the argument that in terms of energy efficiency, you not only want to do insulation, but also DH – or low carbon gas. Which is the most cost-effective ? Could argue reasonable energy efficiency measures are cheapest – but DH might be a better bet. That involves a lot of digging.

    Gas Is The Logical Answer

    But everything’s already laid for gas. (…but from the greatest efficiency first perspective, if you’re not doing DH, you’re not using a lot of Renewable Heat you could otherwise use [...] )

    The best package would be the use of low carbon gases and sufficient DH to use Renewable Heat where it is available – such as desalination, electrolysis or other energy plant. It depends where the electrolysis is being done.

    The Age of Your Carbon

    It also depends on which carbon atoms you’re using. If you are recycling carbon from the combustion of fossil fuels into Renewable Gas, that’s OK. But you can’t easily recapture carbon emissions from the built environment (although you could effectively do that with heat storage). You can’t do carbon capture from transport either. So your low carbon gas has to come from biogenic molecules. Your Renewable Gas has to be synthesised using biogenic carbon molecules rather than fossil ones.

    [...] I’m using the phrase “Young Carbon”. Young Carbon doesn’t have to be from plants – biological things that grow.

    Well, there’s Direct Air Capture (DAC). It’s simple. David Sevier, London-based, is working on this. He’s using heat to capture carbon dioxide. You could do it from exhaust in a chimney or a gasification process – or force a load of air through a space. He would use heat and cooling to create an updraft. It would enable the “beyond capture” problem to be circumvented. Cost is non-competitive. Can be done technically. Using reject heat from power stations for the energy to do it. People don’t realise you can use a lot of heat to capture carbon, not electricity.

    Young Carbon from Seawater

    If you’re playing around with large amounts of seawater anyway – that is, for desalination for irrigation, why not also do Renewable Hydrogen, and pluck the Carbon Dioxide out of there too to react with the Renewable Hydrogen to make Renewable Methane ? I’m talking about very large amounts of seawater. Not “Seawater Greenhouses” – condensation designs mainly for growing exotic food. If you want large amounts of desalinated water – and you’re using Concentrated Solar Power – for irrigating deserts – you would want to grow things like cacti for biological carbon.

    Say you had 40 GW of wind power on Dogger Bank, spinning at 40% load factor a year. You’ve also got electrolysers there. Any time you’re not powering the grid, you’re making gas – so capturing carbon dioxide from seawater, splitting water for hydrogen, making methane gas. Wouldn’t you want to use flash desalination first to get cleaner water for electrolysis ? Straight seawater electrolysis is also being done.

    It depends on the relative quantities of gas concentrated in the seawater. If you’ve got oxygen, hydrogen and carbon dioxide, that would be nice. You might get loads of oxygen and hydrogen, and only poor quantities of carbon dioxide ?

    But if you could get hydrogen production going from spare wind power. And even if you had to pipe the carbon dioxide from conventional thermal power plants, you’re starting to look at a sea-based solution for gas production. Using seawater, though, chlorine is the problem [...]

    Look at the relative density of molecules – that sort of calculation that will show if this is going to fly. Carbon dioxide is a very fixed, stable molecule – it’s at about the bottom of the energy potential well – you have to get that reaction energy from somewhere.

    How Much Spare Power Will There Be ?

    If you’ve got an offshore wind and solar system. At night, obviously, the solar’s not working (unless new cells are built that can run on infrared night-time Earthshine). But you could still have 100 GWh of wind power at night not used for the power grid. The anticipated new nuclear 40 GW nuclear by 2030 will produce about 140 GWh – this would just complicate problems – adding baseload nuclear to a renewables-inclusive scenario. 40 GW is arguably a reasonable deployment of wind power by 2030 – low if anything.

    You get less wind in a nuclear-inclusive scenario, but the upshot is you’ve definitely got a lot of power to deal with on a summer night with nuclear power. You do have with Renewable Electricity as well, but it varies more. Whichever route we take we’re likely to end up with excess electricity generation on summer nights.

    In a 70 GW wind power deployment (50 GW offshore, 20 GW onshore – 160 TWh a year), you might have something like 50 to 100 GWh per night of excess (might get up to 150 GWh to store on a windy night). But if you have a 16 GW nuclear deployment by 2030 (125 TWh a year), you are definitely going to have 140 GWh of excess per night (that’s 16 GW for 10 hours less a bit). Night time by the way is roughly between 9pm and 7am between peak demands.

    We could be making a lot of Renewable Gas !

    Can you build enough Renewable Gas or whatever to soak up this excess nuclear or wind power ?

    The energy mix is likely to be in reality somewhere in between these two extremes of high nuclear or high wind.

    But if you develop a lot of solar – so that it knocks out nuclear power – it will be the summer day excess that’s most significant. And that’s what Germany is experiencing now.

    Choices, choices, choices

    There is a big choice in fossil fuels which isn’t really talked about very often – whether the oil and gas industry should go for unconventional fossil fuels, or attempt to make use of the remaining conventional resources that have a lower quality. The unconventionals narrative – shale gas, coalbed methane, methane hydrates, deepwater gas, Arctic oil and gas, heavy oil, is running out of steam as it becomes clear that some of these choices are expensive, and environmentally damaging (besides their climate change impact). So the option will be making use of gas with high acid gas composition. And the technological solutions for this will be the same as needed to start major production of Renewable Gas.

    Capacity Payments

    But you still need to answer the balancing question. If you have a high nuclear power scenario, you need maybe 50 TWh a year of gas-fired power generation. If high Renewable Electricity, you will need something like 100 TWh of gas, so you need Carbon Capture and Storage – or low carbon gas.

    Even then, the gas power plants could be running only 30% of the year, and so you will need capacity payments to make sure new flexible plants get built and stay available for use.

    If you have a high nuclear scenario, coupled with gas, you can meet the carbon budget – but it will squeeze out Renewable Electricity. If high in renewables, you need Carbon Capture and Storage (CCS) or Carbon Capture and Recycling into Renewable Gas, but this would rule out nuclear power. It depends which sector joins up with which.

    Carbon Capture, Carbon Budget

    Can the Drax power plant – with maybe one pipeline 24 inches in diameter, carrying away 20 megatonnes of carbon dioxide per year – can it meet the UK’s Carbon Budget target ?

  • Gain in Transmission

    Posted on January 13th, 2014 Jo No comments

    It constantly amazes and intrigues me how human individuals operate in networks to formulate, clarify and standardise ideas, tools, machines, procedures and systems. Several decades ago, Renewable Electricity from sources such as wind power was considered idealistic vapourware, esoteric, unworkable and uncertain, and now it’s a mainstream generator of reliable electricity in the UK’s National Grid. Who would have thought that invisible, odourless, tasteless gas phase chemicals would heat our homes ? It’s now just so normal, it’s impossible to imagine that Natural Gas was once considered to be so insignificant that it was vented – not even flared – from oil wells.

    Judging by the sheer number of people working on aspects of Renewable Gas, I expect this too to be mainstream in the energy sector within a decade. What do others think ? I have begun the process of asking, for example, see below.

    Yes, I am interested in the idea of “printing” solar cells, which is what I think you might be alluding to with your reference to abalone shells.

    But I am more interested in what you base your estimate of “Peak Gas” on. I recently did some very basic modelling of hydrocarbon resources and electricity, which look somewhat different from the IEA and EIA work and reports from BP and Royal Dutch Shell. My conclusion was that Peak Oil is roughly now, Peak Natural Gas will be around 2030, and Peak Electricity around 2060 :-

    I am going to try to improve these charts before I submit my MSc Masters Thesis, so I am trying to find out what other people base their projections on. Could you help me by pointing me at the basis of your assessment of Peak Natural Gas ?

    Thank you,

    Jo,

    I am just now finding a number of old emails that got archived (and ignored) when I moved from MIT to Stanford a few years ago. A quick answer is that I did about what Hubbert did in 1956. No detailed statistical modeling, just look at the trends, think about what’s happening in the industry, and make what seem like reasonable statements about it.

    A number of interesting things have happened just in the last two years since you wrote to me. Significantly, US oil production is on the rise. When you count all hydrocarbon liquids, the US is or will soon be, the world largest producer. This just goes to one of my points from TED. Don’t expect oil and gas to go away any time soon. There are plenty of molecules out there. I first said this internally at Shell in the mid 1980′s when I was Manager of Exploration Economics and since then I’ve felt that I got it about right.

    I did just look at your website and would caution you about extrapolating very recent trends into the future. The rate of growth in shale gas production has slowed, but there’s an important economic factor driving that. Gas prices in the US are very low compared to oil. With the development of fraccing technology to enable oil and liquids production from shale formations, the industry has shifted their effort to the liquids-rich plays. A few statistics. Gas is currently around $3.50/mcf. On an energy equivalent basis, this equates to an oil price of about $20/barrel. Brent currently sells for $110/barrel and the light oils produced from the shale plays in the US are getting between $90 and $100/barrel, depending on where they can be delivered. As a consequence, in the 3rd quarter of 2013, compared to one year ago, oil well completions are up 18% while natural gas well completions declined 30%.

    Yes, you are right. Printing solar cells is an example of what I was talking about with Abalone shells. Similarly, what if you had paint that as it dried would self assemble into linked solar cells and your entire house is now generating electricity. I was totally amazed at the number of people that didn’t actually think about what I was saying and called me an !d!*t for imagining that I was going to transform coal itself into some magical new molecule. [...]

    In any case, I think it’s good that you’re thinking about these problems, and importantly it appears from your website that you’re thinking about the system and its complexity.

    Best regards,

    Dear [Professor] Sears,

    Many thanks for your reply.

    I had kinda given up of ever hearing back from you, so it’s lovely to
    read your thoughts.

    May I blog them ?

    Jo,

    I have personally avoided blogging because I don’t want to put up with people writing mean comments about me. But the data is worth sharing. You should also know the sources of that data otherwise you open yourself to more criticism.

    The data on production comes from the International Energy Agency and a research firm PIRA. All of it was in recent press releases. The Energy Information Administration makes similar projections about future production. The data on well completions was recently released by API.

    No need to reference me. The data is out there for all to see. But if you do, fair warning. You will get stupid comments about how I used to be a VP at Shell so of course these are the things I’m going to say. [...]

    By the way, there’s something else that’s very interesting in the world of peak oil and various peaks. I have long believed, as hinted in my TED talk that the most important aspect of peak oil is the demand driven phenomena, not the supply side. It’s worth noting in this context that US oil consumption peaked in 2005 and has declined about 10% since then. This data can be found easily in the BP Statistical Report on World Energy. This is real and is a result of economic shifts, greater efficiency, and the penetration of renewables. Future energy projections (references above) show that this trend continues. A big component of US energy consumption is gasoline, and US gasoline consumption peaked in 2007. I think that data can be found at http://www.eia.gov, although I haven’t looked for it lately. It’s a little factoid that I think I remember.

    Dear Professor Sears,

    HNY 2014 !

    This year I am hoping to attempt the climb on my own personal K2 by writing an academic book on Renewable Gas – sustainable, low-to-zero carbon emissions gas phase fuels.

    I am not a chemist, nor a chemical engineer, and so I would value any suggestions on who I should approach in the gas (and oil) industry to interview about projects that lean in this direction.

    Examples would be :-

    * Power-to-Gas : Using “spare” wind power to make Renewable Hydrogen – for example by electrolysis of water. Part of the German Power-to-Gas policy. Some hydrogen can be added to gas grids safely without changing regulations, pipework or end appliances.

    * Methanation : Using Renewable Hydrogen and young or recycled carbon gas to make methane (using the energy from “spare” wind power, for example). Also part of the German Power-to-Gas policy.

    NB “Young” carbon would be either carbon monoxide or carbon dioxide, and be sourced from biomass, Direct Air Capture, or from the ocean. “Old” carbon would come from the “deeper” geological carbon cycle, such as from fossil fuel, or industrial processes such as the manufacture of chemicals from minerals and/or rocks.

    Precursors to Renewable Gas also interest me, as transitions are important – transitions from a totally fossil fuel-based gas system to a sustainable gas system. I have recently looked at some basic analysis on the chemistry of Natural Gas, and its refinery. It seems that methanation could be useful in making sour gas available as sweetened, as long as Renewable Hydrogen is developed for this purpose. It seems that there is a lot of sour gas in remaining reserves, and the kind of CCS (Carbon Capture and Storage) that would be required under emissions controls could make sour gas too expensive to use if it was just washed of acids.

    I don’t think the future of energy will be completely electrified – it will take a very long time to roll out 100% Renewable Electricity and there will always be problems transitioning out of liquid fuels to electricity in vehicular transportation.

    If you could suggest any names, organisations, university departments, companies, governance bodies that I should contact, or research papers that I should read, I would be highly grateful.

    Many thanks,

    jo.

  • Making The Sour Sweet

    Posted on January 1st, 2014 Jo No comments

    In the long view, some things are inevitable, and I don’t just mean death and taxes. Within the lifetime of children born today, there must be a complete transformation in energy. The future is renewable, and carefully deployed renewable energy systems can be reliable, sustainable and low cost, besides being low in carbon dioxide emissions to air. This climate safety response is also the answer to a degradation and decline in high quality mineral hydrocarbons – the so-called “fossil” fuels. Over the course of 2014 I shall be writing about Renewable Gas – sustainable, low emissions gas fuels made on the surface of the earth without recourse to mining for energy. Renewable Gas can store the energy from currently underused Renewable Electricity from major producers such as wind and solar farms, and help to balance out power we capture from the variable wind and sun. Key chemical players in these fuels : hydrogen, methane, carbon monoxide and carbon dioxide. Key chemistry : how to use hydrogen to recycle the carbon oxides to methane. How we get from here to there is incredibly important, and interestingly, methods and techniques for increasing the production volumes of Renewable Gas will be useful for the gradually fading fossil fuel industry. Much of the world’s remaining easily accessible Natural Gas is “sour” – laced with high concentrations of hydrogen sulfide and carbon dioxide. Hydrogen sulfide needs to be removed from the gas, but carbon dioxide can be recycled into methane, raising the quality of the gas. We can preserve the Arctic from fossil gas exploitation, and save ourselves from this economic burden and ecological risk, by employing relatively cheap ways to upgrade sour Natural Gas, from Iran, for example, while we are on the decades-long road of transitioning to Renewable Gas. The new burn is coming.

  • Mind the Gap : BBC Costing the Earth

    Posted on October 16th, 2013 Jo No comments

    I listened to an interesting mix of myth, mystery and magic on BBC Radio 4.

    Myths included the notion that long-term, nuclear power would be cheap; that “alternative” energy technologies are expensive (well, nuclear power is, but true renewables are most certainly not); and the idea that burning biomass to create heat to create steam to turn turbines to generate electricity is an acceptably efficient use of biomass (it is not).

    Biofuelwatch are hosting a public meeting on this very subject :-
    http://www.biofuelwatch.org.uk/2013/burning_issue_public_event/
    “A Burning Issue – biomass and its impacts on forests and communities”

    Lumen Centre, 88 Tavistock Place, London WC1H 9RS

    Interesting hints in the interviews I thought pointed to the idea that maybe, just maybe, some electricity generation capacity should be wholly owned by the Government – since the country is paying for it one way or another. A socialist model for gas-fired generation capacity that’s used as backup to wind and solar power ? Now there’s an interesting idea…

    “Mind the Gap”
    Channel: BBC Radio 4
    Series: Costing the Earth
    Presenter: Tom Heap
    First broadcast: Tuesday 15th October 2013

    Programme Notes :

    “Our energy needs are growing as our energy supply dwindles.
    Renewables have not come online quickly enough and we are increasingly
    reliant on expensive imported gas or cheap but dirty coal. Last year
    the UK burnt 50% more coal than in previous years but this helped
    reverse years of steadily declining carbon dioxide emissions. By 2015
    6 coal fired power stations will close and the cost of burning coal
    will increase hugely due to the introduction of the carbon price
    floor. Shale gas and biomass have been suggested as quick and easy
    solutions but are they really sustainable, or cheap?”

    “Carbon Capture and Storage could make coal or gas cleaner and a new
    study suggests that with CCS bio energy could even decrease global
    warming. Yet CCS has stalled in the UK and the rest of Europe and the
    debate about the green credentials of biomass is intensifying. So what
    is really the best answer to Britain’s energy needs? Tom Heap
    investigates.”

    00:44 – 00:48
    [ Channel anchor ]
    Britain’s energy needs are top of the agenda in “Costing the Earth”…

    01:17
    [ Channel anchor ]
    …this week on “Costing the Earth”, Tom Heap is asking if our
    ambitions to go green are being lost to the more immediate fear of
    blackouts and brownouts.

    01:27
    [ Music : Arcade Fire - "Neighbourhood 3 (Power Out)" ]

    [ Tom Heap ]

    Energy is suddenly big news – central to politics and the economy. The
    countdown has started towards the imminent shutdown of many coal-fired
    power stations, but the timetable to build their replacements has
    barely begun.

    It’ll cost a lot, we’ll have to pay, and the politicians are reluctant
    to lay out the bill. But both the official regulator and industry are
    warning that a crunch is coming.

    So in this week’s “Costing the Earth”, we ask if the goal of clean,
    green and affordable energy is being lost to a much darker reality.

    02:14
    [ Historical recordings ]

    “The lights have started going out in the West Country : Bristol,
    Exeter and Plymouth have all had their first power cuts this
    afternoon.”

    “One of the biggest effects of the cuts was on traffic, because with
    the traffic lights out of commission, major jams have built up,
    particularly in the town centres. One of the oddest sights I saw is a
    couple of ladies coming out of a hairdressers with towels around their
    heads because the dryers weren’t working.”

    “Television closes down at 10.30 [ pm ], and although the cinemas are
    carrying on more or less normally, some London theatres have had to
    close.”

    “The various [ gas ] boards on both sides of the Pennines admit to
    being taken by surprise with today’s cold spell which brought about
    the cuts.”

    “And now the major scandal sweeping the front pages of the papers this
    morning, the advertisement by the South Eastern Gas Board recommending
    that to save fuel, couples should share their bath.”

    [ Caller ]
    “I shall write to my local gas board and say don’t do it in
    Birmingham. It might be alright for the trendy South, but we don’t
    want it in Birmingham.”

    03:13
    [ Tom Heap ]

    That was 1974.

    Some things have changed today – maybe a more liberal attitude to
    sharing the tub. But some things remain the same – an absence of
    coal-fired electricity – threatening a blackout.

    Back then it was strikes by miners. Now it’s old age of the power
    plants, combined with an EU Directive obliging them to cut their
    sulphur dioxide and nitrous oxide emissions by 2016, or close.

    Some coal burners are avoiding the switch off by substituting wood;
    and mothballed gas stations are also on standby.

    But Dieter Helm, Professor of Energy Policy at the University of
    Oxford, now believes power cuts are likely.

    03:57
    [ Dieter Helm ]

    Well, if we take the numbers produced by the key responsible bodies,
    they predict that there’s a chance that by the winter of 2-15 [sic,
    meaning 2015] 2-16 [sic, meaning 2016], the gap between the demand for
    electricity and the supply could be as low as 2%.

    And it turns out that those forecasts are based on extremely
    optimistic assumptions about how far demand will fall in that period
    (that the “Green Deal” will work, and so on) and that we won’t have
    much economic growth.

    So basically we are on course for a very serious energy crunch by the
    winter of 2-15 [sic, meaning 2015] 2-16 [sic, meaning 2016], almost
    regardless of what happens now, because nobody can build any power
    stations between now and then.

    It’s sort of one of those slow motion car crashes – you see the whole
    symptoms of it, and people have been messing around reforming markets
    and so on, without addressing what’s immediately in front of them.

    [ Tom Heap ]

    And that’s where you think we are now ?

    [ Dieter Helm ]

    I think there’s every risk of doing so.

    Fortunately, the [ General ] Election is a year and a half away, and
    there’s many opportunities for all the political parties to get real
    about two things : get real about the energy crunch in 2-15 [sic,
    meaning 2015] 2-16 [sic, meaning 2016] and how they’re going to handle
    it; and get real about creating the incentives to decarbonise our
    electricity system, and deal with the serious environmental and
    security and competitive issues which our electricity system faces.

    And this is a massive investment requirement [ in ] electricity : all
    those old stations retiring [ originally built ] back from the 1970s -
    they’re all going to be gone.

    Most of the nuclear power stations are coming to the end of their lives.

    We need a really big investment programme. And if you really want an
    investment programme, you have to sit down and work out how you’re
    going to incentivise people to do that building.

    [ Tom Heap ]

    If we want a new energy infrastructure based on renewables and
    carbon-free alternatives, then now is the time to put those incentives
    on the table.

    The problem is that no-one seems to want to make the necessary
    investment, least of all the “Big Six” energy companies, who are
    already under pressure about high bills.

    [ "Big Six" are : British Gas / Centrica, EdF Energy (Electricite
    de France), E.On UK, RWE npower, Scottish Power and SSE ]

    Sam Peacock of the energy company SSE [ Scottish and Southern Energy ]
    gives the commercial proof of Dieter’s prediction.

    If energy generators can’t make money out of generating energy,
    they’ll be reluctant to do it.

    [ Sam Peacock ]

    Ofgem, the energy regulator, has looked at this in a lot of detail,
    and said that around 2015, 2016, things start to get tighter. The
    reason for this is European Directives, [ is [ a ] ] closing down some
    of the old coal plants. And also the current poor economics around [
    or surround [ -ing ] ] both existing plant and potential new plant.

    So, at the moment it’s very, very difficult to make money out of a gas
    plant, or invest in a new one. So this leads to there being, you know,
    something of a crunch point around 2015, 2016, and Ofgem’s analysis
    looks pretty sensible to us.

    [ Tom Heap ]

    And Sam Peacock lays the blame for this crisis firmly at the Government’s door.

    [ Sam Peacock ]

    The trilemma, as they call it – of decarbonisation, security of supply
    and affordability – is being stretched, because the Government’s
    moving us more towards cleaner technologies, which…which are more
    expensive.

    However, if you were to take the costs of, you know, the extra costs
    of developing these technologies off government [ sic, meaning
    customer ] bills and into general taxation, you could knock about over
    £100 off customer bills today, it’ll be bigger in the future, and you
    can still get that much-needed investment going.

    So, we think you can square the circle, but it’s going to take a
    little bit of policy movement [ and ] it’s going to take shifting some
    of those costs off customers and actually back where the policymakers
    should be controlling them.

    [ KLAXON ! Does he mean controlled energy prices ? That sounds a bit
    centrally managed economy to me... ]

    [ Tom Heap ]

    No surprise that a power company would want to shift the pain of
    rising energy costs from their bills to the tax bill.

    But neither the Government nor the Opposition are actually proposing this.

    Who pays the premium for expensve new energy sources is becoming like
    a game of pass the toxic parcel.

    [ Reference : http://en.wikipedia.org/wiki/Hot_potato_%28game%29 ]

    I asked the [ UK Government Department of ] Energy and Climate Change
    Secretary, Ed Davey, how much new money is required between now and
    2020.

    08:06

    [ Ed Davey ]

    About £110 billion – er, that’s critical to replace a lot of the coal
    power stations that are closing, the nuclear power stations that are [
    at the ] end of their lives, and replace a lot of the network which
    has come to the end of its life, too.

    So it’s a huge, massive investment task.

    [ Tom Heap ]

    So in the end we’re going to have to foot the bill for the £110 billion ?

    [ Ed Davey ]

    Yeah. Of course. That’s what happens now. People, in their bills that
    they pay now, are paying for the network costs of investments made
    several years, even several decades ago.

    [ Yes - we're still paying through our national nose to dispose of
    radioactive waste and decommission old nuclear reactors. The liability
    of it all weighs heavily on the country's neck... ]

    And there’s no escaping that – we’ve got to keep the lights on – we’ve
    got to keep the country powered.

    You have to look at both sides of the equation. If we’re helping
    people make their homes more inefficient [ sic, meaning energy
    efficient ], their product appliances more efficient, we’re doing
    everything we possibly can to try to help the bills be kept down,

    while we’re having to make these big investments to keep the lights
    on, and to make sure that we don’t cook the planet, as you say.

    [ Tom Heap ]

    You mention the lights going out. There are predictions that we’re
    headed towards just 2% of spare capacity in the system in a few years’
    time.

    Are you worried about the dangers of, I don’t know, maybe not lights
    going out for some people, but perhaps big energy users being told
    when and when [ sic, meaning where ] they can’t use power in the
    winter ?

    [ Ed Davey ]

    Well, there’s no doubt that as the coal power stations come offline,
    and the nuclear power plants, er, close, we’re going to have make sure
    that new power plants are coming on to replace them.

    And if we don’t, there will be a problem with energy security.

    Now we’ve been working very hard over a long time now to make sure we
    attract that investment. We’ve been working with Ofgem, the regulator;
    with National Grid, and we’re…

    [ Tom Heap ]

    …Being [ or it's being ] tough. I don’t see companies racing to come
    and fill in the gap here and those coal power plants are going off
    soon.

    [ Ed Davey ]

    …we’re actually having record levels of energy investment in the country.

    The problem was for 13 years under the last Government
    [ same old, same old Coalition argument ] we saw low levels of investment
    in energy, and we’re having to race to catch up, but fortunately we’re
    winning that race. And we’re seeing, you know, billions of pounds
    invested but we’ve still got to do more. We’re not there. I’m not
    pretending we’re there yet. [ Are we there, yet ? ] But we do have the
    policies in place.

    So, Ofgem is currently consulting on a set of proposals which will
    enable it to have reserve power to switch on at the peak if it’s
    needed.

    We’re, we’ve, bringing forward proposals in the Energy Bill for what’s
    called a Capacity Market, so we can auction to get that extra capacity
    we need.

    So we’ve got the policies in place.

    [ Tom Heap ]

    Some of Ed Davey’s policies, not least the LibDem [ Liberal Democrat
    Party ] U-turn on nuclear, have been guided by DECC [ Department of
    Energy and Climate Change ] Chief Scientist David MacKay, author of
    the influential book “Renewable Energy without the Hot Air” [ sic,
    actually "Sustainable Energy without the Hot Air" ].

    Does he think the lights will dim in the second half of this decade ?

    [ David MacKay ]

    I don’t think there’s going to be any problem maintaining the capacity
    that we need. We just need to make clear where Electricity Market
    Reform [ EMR, part of the Energy Bill ] is going, and the way in which
    we will be maintaining capacity.

    [ Tom Heap ]

    But I don’t quite understand that, because it seems to me, you know,
    some of those big coal-fired power stations are going to be going off.
    What’s going to be coming in their place ?

    [ David MacKay ]

    Well, the biggest number of power stations that’s been built in the
    last few years are gas power stations, and we just need a few more gas
    power stations like that, to replace the coal
    , and hopefully some
    nuclear power stations will be coming on the bars, as well as the wind
    farms that are being built at the moment.

    [ Tom Heap ]

    And you’re happy with that increase in gas-fired power stations, are
    you ? I mean, you do care deeply, personally, about reducing our
    greenhouse gases, and yet you’re saying we’re going to have to build
    more gas-fired power stations.

    [ David MacKay ]

    I do. Even in many of the pathways that reach the 2050 target, there’s
    still a role for gas in the long-term, because some power sources like
    wind and solar power are intermittent, so if you want to be keeping
    the lights on in 2050 when there’s no wind and there’s no sun, you’re
    going to need some gas power stations there
    . Maybe not operating so
    much of the time as they do today, but there’ll still be a role in
    keeping the lights on.

    [ KLAXON ! If gas plants are used only for peak periods or for backup to
    renewables, then the carbon emissions will be much less than if they are
    running all the time. ]

    [ Tom Heap ]

    Many energy experts though doubt that enough new wind power or nuclear
    capacity could be built fast enough to affect the sums in a big way by
    2020.

    But that isn’t the only critical date looming over our energy system.
    Even more challenging, though more distant, is the legally binding
    objective of cutting greenhouse gas emissions in 2050.

    David MacKay wants that certainty to provide the foundation for energy
    decisions, and he showed me the effect of different choices with the
    “Ultimate Future Energy App”. I was in his office, but anyone can try it online.

    [ David MacKay ]

    It’s a 2050 calculator. It computes energy demand and supply in
    response to your choices, and it computes multiple consequences of
    your choices. It computes carbon consequences. It also computes for
    you estimates of air quality, consequences of different choices;
    security of supply, consequences; and the costs of your choices.

    So with this 2050 calculator, it’s an open source tool, and anyone can
    go on the web and use the levers to imagine different futures in 2050
    of how much action we’ve taken in different demand sectors and in
    different supply sectors.

    The calculator has many visualisations of the pathway that you’re choosing
    and helps people understand all the trade-offs… There’s no silver
    bullet for any of this. If I dial up a pathway someone made earlier,
    we can visualise the implications in terms of the area occupied for
    the onshore wind farms, and the area in the sea for the offshore wind
    farms, and the length of the wave farms that you’ve built, and the
    land area required for energy crops.

    And many organisations have used this tool and some of them have given
    us their preferred pathway. So you can see here the Friends of the
    Earth have got their chosen pathway, the Campaign to Protect Rural
    England, and various engineers like National Grid and Atkins have got
    their pathways.

    So you can see alternative ways of achieving our targets, of keeping
    the lights on and taking climate change action. All of those pathways
    all meet the 2050 target, but they do so with different mixes.

    [ Tom Heap ]

    And your view of this is you sort of can’t escape from the scientific
    logic and rigour of it. You might wish things were different or you
    could do it differently, but you’re sort of saying “Look, it’s either
    one thing or the other”. That’s the point of this.

    [ David MacKay ]

    That’s true. You can’t be anti-everything. You can’t be anti-wind and
    anti-nuclear and anti-home insulation. You won’t end up with a plan
    that adds up.

    [ KLAXON ! But you can be rationally against one or two things, like
    expensive new nuclear power, and carbon and particulate emissions-heavy
    biomass for the generation of electricity. ]

    [ Tom Heap ]

    But isn’t that exactly kind of the problem that we’ve had, without
    pointing political fingers, that people rather have been
    anti-everything, and that’s why we’re sort of not producing enough new
    energy sources ?

    [ David MacKay ]

    Yeah. The majority of the British public I think are in favour of many
    of these sources, but there are strong minorities who are vocally
    opposed to every one of the major levers in this calculator. So one
    aspiration I have for this tool is it may help those people come to a
    position where they have a view that’s actually consistent with the
    goal of keeping the lights on.

    [ Tom Heap ]

    Professor MacKay’s calculator also computes pounds and pence,
    suggesting that both high and low carbon electricity work out pricey
    in the end.

    [ David MacKay ]

    The total costs of all the pathways are pretty much the same.
    “Business as Usual” is cheaper in the early years, and then pays more,
    because on the “Business as Usual”, you carry on using fossil fuels,
    and the prices of those fossil fuels are probably going to go up.

    All of the pathways that take climate change action have a similar
    total cost, but they pay more in the early years, ’cause you have to
    pay for things like building insulation and power stations, like
    nuclear power stations, or wind power, which cost up-front, but then
    they’re very cheap to run in the future.

    [ KLAXON ! Will the cost of decommissioning nuclear reactors and the
    costs of the waste disposal be cheap ? I think not... ]

    So the totals over the 40 or 50 year period here, are much the same for these.

    [ Tom Heap ]

    The cheapest immediate option of all is to keep shovelling the coal.
    And last year coal overtook gas to be our biggest electricity
    generation source, pushing up overall carbon emissions along the way
    by 4.5%

    [ KLAXON ! This is not very good for energy security - look where the
    coal comes from... ]

    As we heard earlier, most coal-fired power stations are scheduled for
    termination, but some have won a reprieve, and trees are their
    unlikely saviour.

    Burning plenty of wood chip [ actually, Tom, it's not wood "chip", it's
    wood "pellets" - which often have other things mixed in with the wood,
    like coal... ] allows coal furnaces to cut the sulphur dioxide and nitrous
    oxide belching from their chimneys to below the level that requires their
    closure under European law.

    But some enthusiasts see wood being good for even more.

    16:19

    [ Outside ]

    It’s one of those Autumn days that promises to be warm, but currently
    is rather moist. I’m in a field surrounded by those dew-laden cobwebs
    you get at this time of year.

    But in the middle of this field is a plantation of willow. And I’m at
    Rothamsted Research with Angela Karp who’s one of the directors here.

    Angela, tell me about this willow I’m standing in front of here. I
    mean, it’s about ten foot high or so, but what are you seeing ?

    [ Angela Karp ]

    Well, I’m seeing one of our better varieties that’s on display here.
    We have a demonstration trial of about ten different varieties. This
    is a good one, because it produces a lot of biomass, quite easily,
    without a lot of additional fertilisers or anything. And as you can
    see it’s got lovely straight stems. It’s got many stems, and at the
    end of three years, we would harvest all those stems to get the
    biomass from it. It’s nice and straight – it’s a lovely-looking, it’s
    got no disease, no insects on it, very nice, clean willow.

    [ Tom Heap ]

    So, what you’ve been working on here as I understand it is trying to
    create is the perfect willow – the most fuel for the least input – and
    the easiest to harvest.

    [ Angela Karp ]

    That’s absolutely correct, because the whole reason for growing these
    crops is to get the carbon from the atmosphere into the wood, and to
    use that wood as a replacement for fossil fuels. Without putting a lot
    of inputs in, because as soon as you add fertilisers you’re using
    energy and carbon to make them, and that kind of defeats the whole
    purpose of doing this.

    [ KLAXON ! You don't need to use fossil fuel energy or petrochemicals or
    anything with carbon emissions to make fertiliser ! ... Hang on, these
    are GM trees, right ? So they will need inputs... ]

    [ Tom Heap ]

    And how much better do you think your new super-variety is, than say,
    what was around, you know, 10 or 15 years ago. ‘Cause willow as an
    idea for burning has been around for a bit. How much of an improvement
    is this one here ?

    [ Angela Karp ]

    Quite a bit. So, these are actually are some of the, if you like,
    middle-term varieties. So we started off yielding about 8 oven-dry
    tonnes per hectare, and now we’ve almost doubled that.

    [ Tom Heap ]

    How big a place do you think biomass can have in the UK’s energy
    picture in the future ?

    [ Angela Karp ]

    I think that it could contribute between 10% and 15% of our energy. If
    we were to cultivate willows on 1 million hectares, we would probably
    provide about 3% to 4% of energy in terms of electricity, and I think
    that’s kind of a baseline figure. We could cultivate them on up to 3
    million hectares, so you can multiply things up, and we could use them
    in a much more energy-efficient way.

    [ KLAXON ! Is that 4% of total energy or 4% of total electricity ?
    Confused. ]

    [ Tom Heap ]

    Do we really have 3 million hectares going a-begging for planting willow in ?

    [ Angela Karp ]

    Actually, surprisingly we do. So, people have this kind of myth
    there’s not enough land, but just look around you and you will find
    there’s lots of land that’s not used for cultivating food crops.

    We don’t see them taking over the whole country. We see them being
    grown synergistically with food crops.

    [ KLAXON ! This is a bit different than the statement made in 2009. ]

    [ Tom Heap ]

    But I’d just like to dig down a little bit more into the carbon cycle
    of the combustion of these things, because that’s been the recent
    criticism of burning a lot of biomass, is that you put an early spike
    in the amount of carbon in the atmosphere, if you start burning a lot
    of biomass, because this [ sounds of rustling ], this plant is going
    to be turned into, well, partly, CO2 in the atmosphere.

    [ Angela Karp ]

    Yes, I think that’s probably a simple and not totally correct way of
    looking at it. ‘Cause a lot depends on the actual conversion process
    you are using.

    So some conversion processes are much more efficient at taking
    everything and converting it into what you want.

    Heat for example is in excess of 80%, 90% conversion efficiency.

    Electricity is a little bit more of the problem. And there, what
    they’re looking at is capturing some of the carbon that you lose, and
    converting that back in, in carbon storage processes, and that’s why
    there’s a lot of talk now about carbon storage from these power
    stations.

    That I think is the future. It’s a question of connecting up all parts
    of the process, and making sure that’s nothing wasted.

    20:02

    [ Tom Heap ]

    So, is wood a desirable greener fuel ?

    Not according to Almuth Ernsting of Biofuelwatch, who objects to the
    current plans for large-scale wood burning, its use to prop up coal,
    and even its low carbon claims.

    [ Almuth Ernsting ]

    The currently-announced industry plans, and by that I mean existing
    power stations, but far more so, power stations which are in the
    planning process [ and ] many of which have already been consented -
    those [ biomass ] power stations, would, if they all go ahead,
    require to burn around 82 million tonnes of biomass, primarily wood,
    every year. Now by comparison, the UK in total only produces around
    10 million tonnes, so one eighth of that amount, in wood, for all
    industries and purposes, every year.

    We are looking on the one hand at a significant number of proposed,
    and in some cases, under-construction or operating new-build biomass
    power stations, but the largest single investment so far going into
    the conversion of coal power station units to biomass, the largest and
    most advanced one of which at the moment is Drax, who are, have
    started to move towards converting half their capacity to burning wood
    pellets.

    [ Tom Heap ]

    Drax is that huge former, or still currently, coal-fired power station
    in Yorkshire, isn’t it ?

    [ Almuth Ernsting ]

    Right, and they still want to keep burning coal as well. I mean, their
    long-term vision, as they’ve announced, would be for 50:50 coal and
    biomass.

    [ Tom Heap ]

    What do you think about that potential growth ?

    [ Almuth Ernsting ]

    Well, we’re seriously concerned. We believe it’s seriously bad news
    for climate change, it’s seriously bad news for forests, and it’s
    really bad news for communities, especially in the Global South, who
    are at risk of losing their land for further expansion of monoculture
    tree plantations, to in future supply new power stations in the UK.

    A really large amount, increasingly so, of the wood being burned,
    comes from slow-growing, whole trees that are cut down for that
    purpose, especially at the moment in temperate forests in North
    America. Now those trees will take many, many decades to grow back
    and potentially re-absorb that carbon dioxide, that’s if they’re
    allowed and able to ever grow back.

    [ Tom Heap ]

    There’s another technology desperate for investment, which is critical
    to avoiding power failure, whilst still hitting our mid-century carbon
    reduction goals – CCS – Carbon Capture and Storage, the ability to
    take the greenhouse gases from the chimney and bury them underground.

    It’s especially useful for biomass and coal, with their relatively
    high carbon emissions, but would also help gas be greener.

    The Chancellor has approved 30 new gas-fired power stations, so long
    as they are CCS-ready [ sic, should be "capture ready", or
    "carbon capture ready" ].

    Jon Gibbons is the boss of the UK CCS Research Centre, based in an
    industrial estate in Sheffield.

    [ Noise of processing plant ]

    Jon’s just brought me up a sort of 3D maze of galvanized steel and
    shiny metal pipes to the top of a tower that must be 20 or so metres
    high.

    Jon, what is this ?

    [ Jon Gibbons ]

    OK, so this is our capture unit, to take the CO2 out of the combustion
    products from gas or coal. In the building behind us, in the test rigs
    we’ve got, the gas turbine or the combustor rig, we’re burning coal or
    gas, or oil, but mainly coal or gas.

    We’re taking the combustion products through the green pipe over
    there, bringing it into the bottom of the unit, and then you can see
    these big tall columns we’ve got, about 18 inches diameter, half a
    metre diameter, coming all the way up from the ground up to the level
    we’re at.

    It goes into one of those, it gets washed clean with water, and it
    goes into this unit over here, and there it meets an amine solvent, a
    chemical that will react reversibly with CO2, coming in the opposite
    direction, over packing. So, it’s like sort of pebbles, if you can
    imagine it, there’s a lot of surface area. The gas flows up, the
    liquid flows down, and it picks up the CO2, just mainly the CO2.

    [ Tom Heap ]

    And that amine, that chemical as you call it, is stripping the CO2 out
    of that exhaust gas. This will link to a storage facility.

    What would then happen to the CO2 ?

    [ Jon Gibbons ]

    What would then happen is that the CO2 would be compressed up to
    somewhere in excess of about 100 atmospheres. And it would turn from
    being a gas into something that looks like a liquid, like water, about
    the same density as water. And then it would be taken offshore in the
    UK, probably tens or hundreds of kilometres offshore, and it would go
    deep, deep down, over a kilometre down into the ground, and basically
    get squeezed into stuff that looks like solid rock. If you go and look
    at a sandstone building – looks solid, but actually, maybe a third of
    it is little holes. And underground, where you’ve got cubic kilometres
    of space, those little holes add up to an awful lot of free space. And
    the CO2 gets squeezed into those, over time, and it spreads out, and
    it just basically sits there forever, dissolves in the water, reacts
    with the rocks, and will stay there for millions of years.

    [ Tom Heap ]

    Back in his office, I asked Jon why CCS seemed to be stuck in the lab.

    [ Jon Gibbons ]

    We’re doing enough I think on the research side, but what we really
    need to do, is to do work on a full-scale deployment. Because you
    can’t work on research in a vacuum. You need to get feedback -
    learning by doing – from actual real projects.

    And a lot of the problems we’ve got on delivering CCS, are to do with
    how you handle the regulation for injecting CO2, and again, you can
    only do that in real life.

    So what we need to do is to see the commercialisation projects that
    are being run by the Department of Energy and Climate Change actually
    going through to real projects that can be delivered.

    [ Tom Heap ]

    Hmm. When I talk to engineers, they’re always very passionate and
    actually quite optimistic about Carbon Capture and Storage. And when
    I talk to people in industry, or indeed read the headlines, not least
    a recent cancellation in Norway, it always seems like a very bleak picture.

    [ Jon Gibbons ]

    I think people are recognising that it’s getting quite hard to get
    money for low carbon technologies.

    So – recent presentation we had at one of our centre meetings, was
    actually a professor from the United States, Howard Herzog. And he
    said “You think you’re seeing a crisis in Carbon Capture and Storage.
    But what you’re actually seeing is a crisis in climate change
    mitigation.”

    [ KLAXON ! Priming us for a scaling back of commitment to the
    Climate Change Act ? I do hope not. ]

    Now, Carbon Capture and Storage, you do for no other purpose than
    cutting CO2 emissions to the atmosphere, and it does that extremely
    effectively. It’s an essential technology for cutting emissions. But
    until you’ve got a global process that says – actually we’re going to
    get on top of this problem; we’re going to cut emissions – get them to
    safe level before we actually see people dying in large numbers from
    climate change effects – ’cause, certainly, if people start dying,
    then we will see a response – but ideally, you’d like to do it before
    then. But until you get that going, then actually persuading people to
    spend money for no other benefit than sorting out the climate is
    difficult.

    There’s just no point, you know, no country can go it alone, so you
    have to get accommodation. And there, we’re going through various
    processes to debate that. Maybe people will come to an accommodation.
    Maybe the USA and China will agree to tackle climate change. Maybe
    they won’t.

    What I am fairly confident is that you won’t see huge, you know,
    really big cuts in CO2 emissions without that global agreement. But
    I’m also confident that you won’t see big cuts in CO2 emissions
    without CCS deployment.

    And my guess is there’s about a 50:50 chance that we do CCS before we
    need to, and about a 50:50 chance we do it after we have to. But I’m
    pretty damn certain we’re going to do it.

    [ Tom Heap ]

    But we can’t wait for a global agreement that’s already been decades
    in the making, with still no end in sight.

    We need decisions now to provide more power with less pollution.

    [ Music lyrics : "What's the plan ? What's the plan ?" ]

    [ Tom Heap ]

    Dieter Helm, Professor of Energy Policy at the University of Oxford
    believes we can only deliver our plentiful green energy future if we
    abandon our attitude of buy-now pay-later.

    [ KLAXON ! Does he mean a kind of hire purchase energy economy ?
    I mean, we're still paying for nuclear electricity from decades ago,
    in our bills, and through our taxes to the Department of Energy and
    Climate Change. ]

    [ Dieter Helm ]

    There’s a short-term requirement and a long-term requirement. The
    short-term requirement is that we’re now in a real pickle. We face
    this energy crunch. We’ve got to try to make the best of what we’ve
    got. And I think it’s really like, you know, trying to get the
    Spitfires back up again during the Battle of Britain. You know, you
    patch and mend. You need somebody in command. You need someone
    in control. And you do the best with what you’ve got.

    In that context, we then have to really stand back and say, “And this
    is what we have to do to get a serious, long-term, continuous, stable
    investment environment, going forward.” In which, you know, we pay the
    costs, but of course, not any monopoly profits, not any excess
    profits, but we have a world in which the price of electricity is
    related to the cost.”

  • Wind Powers Energy Security #2

    Posted on August 18th, 2013 Jo No comments

    There’s no doubt about it – wind power is saving the grid. Since the economic deflation (otherwise more sensitively termed a “recession” or a “slowdown”), and the consequent drop in confidence about the growth in electricity demand, and the problem of “missing money” to finance new infrastructure projects, there has not been much investor appetite for commissioning new power plants running on “conventional” fossil fuels. But wind is raging away with 12 gigawatts of wind power capacity added in the European Union in 2012.

    But can wind be relied on ? Well, there’s lots of wind, and so lots of wind power – in the UK, for example, wind turbines generated 16,884 gigawatt hours of power in 2012, more than double the amount in 2008 (DUKES Digest of UK Energy Statistics, Table 5.1).

    But what if the wind dies down when a high pressure weather system sits tight over the UK in the depths of winter ? What “Equivalent Firm Capacity” (EFC) can we expect from wind power ? Ofgem models 17% of the total in their 2013 Electricity Capacity Assessment Report. National Grid modelled 8% in their Winter Outlook Report of 2011/2012, which went up to 10% in the Winter Outlook for 2012/2013, and 10% in the 2013/2014 Winter Consultation Report (but noted that actual availability of wind during the previous year winter high demand conditions had been 9%)

    Views and evidence differ about whether wind power availability is destined to be so low in winter cold highs – whether calm conditions are bound to be experienced at the same time as high power demand. Both the National Grid and Ofgem, the UK Government’s energy market regulator, have modelled this from data, but just as the time series is relatively short, the number of wind generators is rapidly increasing, so the richness of the data has yet to improve.

    The problem with concentrating on the winter is that the excellent contribution from wind power to indigenous electricity generation is obscured. Clearly that’s the intention of the wind power deniers, who dismiss wind power’s valuable contribution because of the risk of some still days in December or January.

    For any time of the year apart from the deepest cold of winter, wind power is a healthy generation resource. In some cases, wind power is embedded into industrial, military and transport facilities and isn’t metered by National Grid, and at times of high wind generation, National Grid experiences a “negative demand” effect on the main power grid.

    And here are just some of the reasons why the contribution of wind power to national energy security is going to improve :-

    1. A wider geographical spread of wind farms

    More wind power will almost certainly be built. And built fast. Wind turbines have a good Net Present Value, so are assets, as opposed to nuclear reactors which start depreciating in return value the moment you start pouring concrete. Wind turbines are also quick to deploy, compared to the interminable struggle to commit to building other sorts of generation. The reason why wind power is fast to grid is because of slight tilts in market conditions caused by government subsidies and other measures to favour their low carbon generation. The only other contender (besides solar electric) for speed to grid generation from first groundworks is new efficient Natural Gas-fired plant. While people are still debating whether or not to deploy other forms of low carbon generation, wind power and gas (and solar electric) will be ripping up the projection spreadsheets. As more wind power comes online, there will naturally be a wider geographical dispersion of resources. If wind power generation capacity is spread over distances wider than the average anti-cyclonic high pressure system, then higher capacity values can be guaranteed. The more wind power there is, the firmer the promise of power will be.

    2. The development of wind power hubs serving a number of regions

    Already we see wind power “hubs” emerging, centres of build and connection of wind farms where conditions, financing and planning are more favourable. Some of these projects are international, such as in the North Sea area. With the plans for growing the integrated wind power market over a larger number of territories comes the flexibility to use wind power where it’s most needed at any one time, almost certainly raising the levels of wind energy that can be supplied to consumers from the same quantity of generation equipment. If “spare” wind capacity can flow through beefed up European power networks to serve regional demand, then there will be more reason to count on wind.

    3. Size of wind turbines – and height

    Data modelling of wind power will need to adjust to new realities – larger and higher wind turbines – capturing more of the wind for power generation. Wind flow is more regular the higher you are from the surface of the land or sea, so stronger dependency on wind power will be possible in future.

    4. The synergy between low carbon generation technologies

    So you’ve hit a rough patch with low wind speeds today – but solar power is doing fine. Or tidal energy. The more renewable energy technologies we develop, the more they can support each other in their respective weaknesses, so firming up renewable energy capacity as a whole.

    5. The development of hybrid wind systems

    Already, levels of installed wind generation capacity mean that there are periods of unused wind. Part of this will be improved by strengthening transmission networks, and this will improve wind’s reliability by getting “stranded” wind power to market. If the spare or surplus, or even “constrained” or “curtailed” wind power could be put to use as part of a Power to Gas hybrid system, more of the wind energy could be captured for a more reliable source of electrical power. This is just one angle of the Renewable Gas story – there are already several wind-to-hydrogen projects testing the concept of using electrolysis of water by spare wind power to produce hydrogen gas that can be stored and burned later on for power generation.

  • Wind Powers Electricity Security

    Posted on August 17th, 2013 Jo No comments




    Have the anti-wind power lobby struck again ? A seemingly turbulent researcher from Private Eye magazine rang me on Thursday evening to ask me to revise my interpretation of his “Keeping The Lights On” piece of a few weeks previously. His article seemed at first glance to be quite derogatory regarding the contribution of wind power to the UK’s electricity supply. If I were to look again, I would find out, he was sure, that I was wrong, and he was right.

    So I have been re-reviewing the annual 2013 “Electricity Capacity Assessment Report” prepared by Ofgem, the UK Government’s Office of Gas and Electricity Markets, an independent National Regulatory Authority. I have tried to be as fair-minded and generous as possible to “Old Sparky” at Private Eye magazine, but a close re-reading of the Ofgem report suggests he is apparently mistaken – wind power is a boon, not a burden (as he seems to claim).

    In the overview to the Ofgem report, they state, “our assessment suggests that the risks to electricity security of supply over the next six winters have increased since our last report in October 2012. This is due in particular to deterioration in the supply-side outlook. There is also uncertainty over projected reductions in demand.” Neither of these issues can be associated with wind power, which is being deployed at an accelerating rate and so is providing increasing amounts of electricity.

    The report considers risks to security of the electricity supply, not an evaluation of the actual amounts of power that will be supplied. How are these risks to the security of supply quantified ? There are several metrics provided from Ofgem’s modelling, including :-

    a. LOLE – Loss of Load Expectation – the average number of hours per year in which electricity supply does not meet electricity demand (if the grid System Operator does not take steps to balance it out).

    (Note that Ofgem’s definition of LOLE is difference from other people’s “LOLE is often interpreted in the academic literature as representing the probability of disconnections after all mitigation actions available to the System Operator have been exhausted. We consider that a well functioning market should avoid using mitigation actions in [sic] regular basis and as such we interpret LOLE as the probability of having to implement mitigation actions.”)

    b. EEU – Expected Energy Unserved (or “Un-served”) – the average amount of electricity demand that is not met in a year – a metric that combines both the likelihood and the size of any shortfall.

    c. Frequency and Duration of Expected Outages – a measure of the risk that an electricity consumer faces of controlled disconnection because supply does not meet demand.

    The first important thing to note is that the lights are very unlikely to go out. The highest value of LOLE, measured in hours per year is under 20. That’s 20 hours each year. Not 20 days. And this is not anticipated to be 20 days in a row, either. Section 1.11 says “LOLE, as interpreted in this report, is not a measure of the expected number of hours per year in which customers may be disconnected. For a given level of LOLE and EEU, results may come from a large number of small events where demand exceeds supply in principle but that can be managed by National Grid through a set of mitigation actions available to them as System Operator. [...] Given the characteristics of the GB system, any shortfall is more likely to take the form of a large number of small events that would not have a direct impact on customers.”

    Section 2.19 states, “The probabilistic measures of security of supply presented in this report are often misinterpreted. LOLE is the expected number of hours per year in which supply does not meet demand. This does not however mean that customers will be disconnected or that there will be blackouts for that number of hours a year. Most of the time, when available supply is not high enough to meet demand, National Grid may implement mitigation actions to solve the problem without disconnecting any customers. However, the system should be planned to avoid the use of mitigation actions and that is why we measure LOLE ahead of any mitigation actions being used”. And Section 2.20, “LOLE does not necessarily mean disconnections but they do remain a possibility. If the difference between available supply and demand is so large that the mitigation actions are not enough to meet demand then some customers have to be disconnected – this is the controlled disconnections step in Figure 14 above. In this case the [System Operator] SO will disconnect industrial demand before household demand.”

    And in Section 2.21. “The model output numbers presented here refer to a loss of load of any kind. This could be the sum of several small events (controlled through mitigation actions) or a single large event. As a consequence of the mitigation actions available, the total period of disconnections for a customer will be lower than the value of LOLE.”

    The report does anticipate that there are risks of large events where the lights could go out, even if only very briefly, for non-emergency customers : “The results may also come from a small number of large events (eg the supply deficit is more than 2 – 3 gigawatts (GW)) where controlled disconnections cannot be avoided.” But in this kind of scenario two very important things would happen. Those with electricity contracts with a clause permitting forced disconnection would lose power. And immediate backup power generation would be called upon to bridge the gap. There are many kinds of electricity generation that can be called on to start up in a supply crisis – some of them becoming operational in minutes, and others in hours.

    As the report says in Section 2.24 “Each [Distribution Network Operator] DNO ensures it can provide a 20% reduction of its total system demand in four incremental stages (between 4% and 6%), which can be achieved at all times, with or without prior warning, and within 5 minutes of receipt of an instruction from the System Operator. The reduction of a further 20% (40% in total) can be achieved following issue of the appropriate GB System Warning by National Grid within agreed timescales”.

    It’s all about the need for National Grid to balance the system. Section 2.9 says, “LOLE is not a measure of the expected number of hours per year in which customers may be disconnected. We define LOLE to indicate the number of hours in which the system may need to respond to tight conditions.”

    The report also rules some potential sources of disruption of supply outside the remit of this particular analysis – see Section 3.17 “There are other reasons why electricity consumers might experience disruptions to supply, which are out of the scope of this assessment and thus not captured by this model, such as: Flexibility : The ability of generators to ramp up in response to rapid increases in demand or decreases in the output of other generators; Insufficient reserve : Unexpected increases in demand or decreases in available capacity in real time which must be managed by the System Operator through procurement and use of reserve capacity; Network outages : Failures on the electricity transmission or distribution networks; Fuel availability : The availability of the fuel used by generators. In particular the security of supplies of natural gas at times of peak electricity demand.”

    Crucially, the report says there is much uncertainty in their modelling of LOLE and EEU. In Section 2.26, “The LOLE and EEU estimates are just an indication of risk. There is considerable uncertainty around the main variables in the calculation (eg demand, the behaviour of interconnectors etc.)”

    (Note : interconnectors are electricity supply cables that join the UK to other countries such as Ireland and Holland).

    Part of the reason for Ofgem’s caveat of uncertainty is the lack of appropriate data. Although they believe they have better modelling of wind power since their 2012 report (see Sections 3.39 to 3.50), there are data sets they believe should be improved. For example, data on Demand Side Response (DSR) – the ability of the National Grid and its larger or aggregated consumers to alter levels of demand on cue (see Sections 4.7 to 4.10 of the document detailing decisions about the methodology). A lack of data has led to certain assumptions being retained, for example, the assumption that there is no relationship between available wind power and periods of high demand – in the winter season (see Section 2.5 and Sections 4.11 to 4.17 of the methodology decisions document).

    In addition to these uncertainties, the sensitivity cases used in the modelling are known to not accurately reflect the capability of management of the power grid. In the Executive Summary on page 4, the report says, “These sensitivities only illustrate changes in one variable at a time and so do not capture potential mitigating effects, for example of the supply side reacting to higher demand projections.” And in Section 2.16 it says, “Each sensitivity assumes a change in one variable from the Reference Scenario, with all other assumptions being held constant. The purpose of this is to assess the impact of the uncertainty related to each variable in isolation, on the risk measures. Our report is not using scenarios (ie a combination of changes in several variables to reflect alternative worlds or different futures), as this would not allow us to isolate the impact of each variable on the risk measures.”

    Thus, the numbers that are output by the modelling are perforce illustrative, not definitive.

    What “Old Sparky” at Private Eye was rattled by in his recent piece was the calculation of Equivalent Firm Capacity (EFC) in the Ofgem report.

    On page 87, Section 3.55, the Ofgem report defines the “standard measure” EFC as “the amount of capacity that is required to replace the wind capacity to achieve the same level of LOLE”, meaning the amount of always-on generation capacity required to replace the wind capacity to achieve the same level of LOLE. Putting it another way on page 33, in the footnotes for Section 3.29, the report states, “The EFC is the quantity of firm capacity (ie always available) that can be replaced by a certain volume of wind generation to give the same level of security of supply, as measured by LOLE.”

    Wind power is different from fossil fuel-powered generation as there is a lot of variability in output. Section 1.48 of the report says, “Wind generation capacity is analysed separately given that its outcome in terms of generation availability is much more variable and difficult to predict.” Several of the indicators calculated for the report are connected with the impact of wind on security of the power supply. However, variation in wind power is not the underlying reason for the necessity of this report. Other electricity generation plant has variation in output leading to questions of security of supply. In addition, besides planned plant closures and openings, there are as-yet-unknown factors that could impact overall generation capacity. Section 2.2 reads, “We use a probabilistic approach to assess the uncertainty related to short-term variations in demand and available conventional generation due to outages and wind generation. This is combined with sensitivity analysis to assess the uncertainty related to the evolution of electricity demand and supply due to investment and retirement decisions (ie mothballing, closures) and interconnector flows, among others.”

    The report examines the possibility that wind power availability could be correlated to winter season peak demand, based on limited available data, and models a “Wind Generation Availability” sensitivity (see Section 3.94 to Section 3.98, especially Figure 64). In Section 3.42 the report says, “For the wind generation availability sensitivity we assume that wind availability decreases at time of high demand. In particular this sensitivity assumes a reduction in the available wind resource for demand levels higher than 92% of the ACS peak demand. The maximum reduction is assumed to be 50% for demand levels higher than 102% of ACS peak demand.” Bear in mind that this is only an assumption.

    In Appendix 5 “Detailed results tables”, Table 34, Table 35 and Table 37 show how this modelling impacts the calculation of the indicative Equivalent Firm Capacity (EFC) of wind power.

    In the 2018/2019 timeframe, when there is expected to be a combined wind power capacity of 8405 megawatts (MW) onshore plus 11705 MW offshore = 20110 MW, the EFC for wind power is calculated to be 2546 MW in the “Wind Generation Availability” sensitivity line, which works out at 12.66% of the nameplate capacity of the wind power. Note : 100 divided by 12.66 is 7.88, or a factor of roughly 8.

    At the earlier 2013/2014 timeframe, when combined wind power capacity is expected to be 3970 + 6235 MW = 10205 MW, and the EFC is at 1624 MW or 15.91% for the “Wind Generation Sensitivity” line. Note : 100 divided by 15.91 = 6.285, or a factor of roughly 6.

    “Old Sparky” is referring to these factor figures when he says in his piece (see below) :-

    “[...] For every one megawatt of reliable capacity (eg a coal-fired power
    station) that gets closed, Ofgem calculates Britain would need six to
    eight
    megawatts of windfarm capacity to achieve the original level of
    reliability – and the multiple is rising all the time. Windfarms are
    not of course being built at eight times the rate coal plants are
    closing – hence the ever-increasing likelihood of blackouts. [...]”

    Yet he has ignored several caveats given in the report that place these factors in doubt. For example, the sensitivity analysis only varies one factor at a time and does not attempt to model correlated changes in other variables. He has also omitted to consider the relative impacts of change.

    If he were to contrast his statement with the “Conventional Low Generation Availability” sensitivity line, where wind power EFC in the 2013/2014 timeframe is calculated as a healthy 26.59% or a factor of roughly 4; or 2018/2019 when wind EFC is 19.80% or a factor of roughly 5.

    Note : The “Conventional Low Generation Availability” sensitivity is drawn from historical conventional generation operating data, as outlined in Sections 3.31 to 3.38. Section 3.36 states, “The Reference Scenario availability is defined as the mean availability of the seven winter estimates. The availability values used for the low (high) availability sensitivities are defined as the mean minus (plus) one standard deviation of the seven winter estimates.”

    Table 30 and Table 31 show that low conventional generation availability will probably be the largest contribution to energy security uncertainty in the critical 2015/2016 timeframe.

    The upshot of all of this modelling is that wind power is actually off the hook. Unforeseen alterations in conventional generation capacity are likely to have the largest impact. As the report says in Section 4.21 “The figures indicate that reasonably small changes in conventional generation availability have a material impact on the risk of supply shortfalls. This is most notable in 2015/16, where the estimated LOLE ranges from 0.2 hours per year in the high availability sensitivity to 16 hours per year in the low availability sensitivity, for the Reference Scenario is 2.9 hours per year.”

    However, Section 1.19 is careful to remind us, “Wind generation, onshore and offshore, is expected to grow rapidly in the period of analysis and especially after 2015/16, rising from around 9GW of installed capacity now to more than 20GW by 2018/19. Given the variability of wind speeds, we estimate that only 17% of this capacity can be counted as firm (ie always available) for security of supply purposes by 2018/19.” This is in the Reference Scenario.

    The sensitivities modelled in the report are a measure of risk, and do not provide absolute values for any of the output metrics, especially since the calculations are dependent on so many factors, including economic stimulus for the building of new generation plant.

    Importantly, recent decisions by gas-fired power plant operators to “mothball”, or close down their generation capacity, are inevitably going to matter more than how much exactly we can rely on wind power.

    Many commentators neglect to make the obvious point that wind power is not being used to replace conventional generation entirely, but to save fossil fuel by reducing the number of hours conventional generators have to run. This is contributing to energy security, by reducing the cost of fossil fuel that needs to be imported. However, the knock-on effect is this is having an impact on the economic viability of these plant because they are not always in use, and so the UK Government is putting in place the “Capacity Mechanism” to make sure that mothballed plant can be put back into use when required, during those becalmed, winter afternoons when power demand is at its peak.

    “Keeping the Lights On”
    page 14
    by “Old Sparky”

    The report from energy regulator Ofgem that sparked headlines on
    potential power cuts contains much new analysis highlighting the
    uselessness of wind generation in contributing to security of
    electricity supply, aka the problem of windfarm “intermittency”. But
    the problem is being studiously ignored by the Department of Energy
    and Climate Change (DECC).

    As coal power stations shut down, windfarms are notionally replacing
    them. If, say, only one windfarm were serving the grid, its inherent
    unreliability could easily be compensated for. But if there were
    [italics] only windfarms, and no reliable sources of electricity
    available at all, security of supply would be hugely at risk. Thus the
    more windfarms there are, the less they contribute to security.

    For every one megawatt of reliable capacity (eg a coal-fired power
    station) that gets closed, Ofgem calculates Britain would need six to
    eight megawatts of windfarm capacity to achieve the original level of
    reliability – and the multiple is rising all the time. Windfarms are
    not of course being built at eight times the rate coal plants are
    closing – hence the ever-increasing likelihood of blackouts.

    [...]

    In consequence windfarms are being featherbedded – not only with
    lavish subsidies, but also by not being billed for the ever-increasing
    trouble they cause. When the DECC was still operating Plan B, aka the
    dash for gas ([Private] Eye [Issue] 1266), the cost of intermittency
    was defined in terms of balancing the grid by using relatively clean
    and cheap natural gas. Now that the department has been forced to
    adopt emergency Plan C ([Private] Eye [Issue] 1344), backup for
    intermittent windfarm output will increasingly be provided by dirty,
    expensive diesel generators.

    “Keeping the Lights On”

    As pandemonium breaks out in newspapers at the prospect of electricity
    blackouts, emergency measures are being cobbled together to ensure the
    lights stay on. They will probably succeed – but at a cost.

    Three years ago incoming coalition ministers were briefed that when
    energy policy Plan A (windfarms, new nukes and pixie-dust) failed, Plan B
    would be in place – a new dash for gas ([Private] Eye [Issue] 1266).

    Civil servants then devised complex “energy market reforms” (EMR) to make
    this happen. It is now clear that these, too, have failed. Coal-fired power
    stations are closing quicker than new gas plants are being built. As energy
    regulator Ofgem put it bluntly last week: “The EMR aims to incentivise
    industry to address security of supply in the medium term, but is not able
    to bring forward investment in new capacity in time.”

    Practical people in the National Grid are now hatching emergency Plan C.
    They will pay large electricity users to switch off when requested;
    encourage industrial companies and even hospitals to generate their own
    diesel-fired electricity (not a hard sell when the grid can’t be relied
    on); hire diesel generators to make up for the intermittency of windfarms
    ([Private] Eye [Issue] 1322); and bribe electricity companies to bring
    mothballed gas-fired plants back into service.

    Some of these steps are based on techniques previously used in extreme
    circumstances, and will probably keep most of the lights on. But this
    should not obscure the fact that planning routine use of emergency
    measures is an indictment of energy policy. And since diesel is much
    more expensive and polluting than gas, electricity prices and CO2
    emissions will be higher than if Plan B had worked.

  • Keith MacLean : Big Choices

    Posted on July 15th, 2013 Jo 3 comments

    At last week’s 2013 Annual Conference for PRASEG, the UK parliamentary sustainable energy group, Keith MacLean from Scottish and Southern Energy outlined (see below) the major pathways for domestic (residential) energy, currently dependent on both a gas grid and a power grid.

    He said that decarbonising heat requires significant, strategic infrastructure decisions on the various proposals and technology choices put forward, as “these options are incompatible”. He said that the UK “need to facilitate more towards ONE of those scenarios/configurations [for provision for heating at home] as they are mutually exclusive”.

    There has been a commitment from Central Government in the UK to the concept of electrification of the energy requirements of both the transport and heat sectors, and Keith MacLean painted a scenario that could see the nation’s households ditching their gas central heating boilers for heat pumps in accord with that vision. Next, “the District Heating (DH) movement could take off, [where you stop using your heat pump and take local piped heat from a Combined Heat and Power (CHP) plant] until there is no spare market capacity. Then [big utilities] could start pumping biogas and hydrogen into the gas grid, and you get your boiler back !”

    Since I view gas grid injection of Renewable Gas feedstocks as a potential way to easily decarbonise the gas supply, and as Keith MacLean said in his panel presentation, “The real opportunity to make a difference in our domestic [residential] energy consumption is in heat rather than power”, I sought him out during the drinks reception after the event, to compare notes.

    I explained that I appreciate the awkward problem he posed, and that my continuing research interest is in Renewable Gas, which includes Renewable Hydrogen, BioHydrogen and BioMethane. I said I had been reading up on and speaking with some of those doing Hydrogen injection into the gas grid, and it looks like a useful way to decarbonise gas.

    I said that if we could get 5% of the gas grid supply replaced with hydrogen…”Yes”, said Keith, “we wouldn’t even need to change appliances at those levels”… and then top up with biogas and other industrial gas streams, we could decarbonise the grid by around 20% without breaking into a sweat. At this point, Keith MacLean started nodding healhily, and a woman from a communications company standing near us started to zone out, so I figured this was getting really interesting. “And that would be significant”, I accented, but by this time she was almost asleep on her feet.

    With such important decisions ahead of us, it seems that people could be paying a bit more attention to these questions. These are, after all, big choices.

    What did Keith mean by “The District Heating movement” ? Well, Dave Andrews of Clean Power (Finning Power Systems), had offered to give a very short presentation at the event. Here was his proposed title :-

    http://uk.groups.yahoo.com/group/Claverton/message/12361
    “Indicative costs of decarbonizing European city heating with electrical distribution compared to district heating pipe distribution of large scale wind energy and with particular attention to transition to the above methods and energy storage costs to address intermittency and variability of wind power.”

    This would have been an assessment of the relative costs of decarbonising European city heating with either :-

    Strategy 1)

    “Gas-fired Combined Cycle Gas Turbine (CCGT) generation plant plus domestic (residential sector) electric heat pumps as the transition solution; and in the long term, large scale wind energy replacing the CCGT – which is retained as back up for low wind situations; and with pumped hydro electrical storage to deal with intermittency /variability of wind energy and to reduce back up fuel usage.”

    or

    Strategy 2)

    “CCGT Combined Heat and Power (CHP) plus district heat (DH) as the transition solution; and in the long term, large scale wind energy replacing the CCGT CHP heat but with the CCGT retained as back up for low wind situations and with hot water energy storage to deal with intermittency / variability and to reduce back up fuel usage.”

    With “the impact of [a programme of building retrofits for] insulation on each strategy is also assessed.”

    Dave’s European research background is of relevance here, as co-author of a 215-pager SETIS programme paper complete with pretty diagrams :-

    http://setis.ec.europa.eu/system/files/1.DHCpotentials.pdf

    Although Dave Andrews was also at the PRASEG drinks reception, he didn’t get the opportunity to address the conference. Which was a shame as his shirt was electric.

    “Keeping the Lights on: At What Cost?”
    Parliamentary Renewable and Sustainable Energy Group
    Annual Conference

    Second Panel Discussion
    Chaired by Baroness Maddock
    “Negawatts: Decentralising and reducing demand – essential or ephemeral ?”

    [Note : The term "negawatt" denotes a negative watt hour - produced by a reduction in power or gas demand. ]

    [...]

    Keith MacLean, Scottish and Southern Energy

    Decentralisation and Demand Reduction [should only be done where] it makes sense. Answers [to the question of negawatts] are very different if looking at Heat and Power. Heat is something far more readily stored that electricity is. Can be used to help balance [the electricity demand profile]. And heat is already very localised [therefore adding to optimising local response]. Some are going in the other direction – looking at district [scale] heating (DH) [using the more efficient system of Combined Heat and Power (CHP)]. Never forget the option to convert from electricity to heat and back to electricity to balance [the grid]. Average household uses 3 MWh (megawatt hours) of electricity [per year] and 15 MWh of heat. The real opportunity is heat. New homes reduce this to about 1 [MWh]. Those built to the new 2016 housing regulations on Zero Carbon Homes, should use around zero. The real opportunity to make a difference in our domestic [residential] energy consumption is in heat rather than power. Reducing consumption not always the right solution. With intermittents [renewable energy] want to switch ON at some times [to soak up cheap wind power in windy conditions]. [A lot of talk about National Grid having to do load] balancing [on the scale of] seconds, minutes and hours. Far more fundamental is the overall system adequacy – a bigger challenge – the long-term needs of the consumer. Keeping the lights from going out by telling people to turn off the lights is not a good way of doing it. There is justifiable demand [for a range of energy services]. [...] I don’t think we’re politically brave enough to vary the [electricity] prices enough to make changes. We need to look at ways of aggregating and automating Demand Side Response. Need to be prepared to legislate and regulate if that is the right solution.

    [...]

    Questions from the Floor

    Question from John Gibbons of the University of Edinburgh

    The decarbonisation of heat. Will we be successful any time soon ?

    Answer from Keith MacLean

    [...] Decarbonising heat – [strategic] infrastructure decisions. For example, [we could go down the route of ditching Natural Gas central heating] boilers for heat pumps [as the UK Government and National Grid have modelled and projected]. Then the District Heating (DH) movement could take off [and you ditch your heat pump at home], until there is no spare market capacity. Then [big utilities] could start pumping biogas and hydrogen into the gas grid, and you get your boiler back ! Need to facilitate more towards ONE of those scenarios/configurations [for provision for heating at home] as mutually exclusive. Need to address in terms of infrastructure since these options are incompatible.

    Answer from Dave Openshaw, Future Networks, UK Power Network

    Lifestyle decision – scope for [action on] heat more than for electricity. Demand Management – managing that Demand Side Reduction and Demand Reduction when need it. Bringing forward use of electricity [in variety of new applications] when know over-supply [from renewable energy, supplied at negative cost].

  • James Delingpole : Worsely Wronger

    Posted on July 15th, 2013 Jo 4 comments

    I wonder to myself – how wrong can James Delingpole get ? He, and Christopher Booker and Richard North, have recently attempted to describe something very, very simple in the National Grid’s plans to keep the lights on. And have failed, in my view. Utterly. In my humble opinion, it’s a crying shame that they appear to influence others.

    “Dellingpole” (sic) in the Daily Mail, claims that the STOR – the Short Term Operating Reserve (not “Operational” as “Dellingpole” writes) is “secret”, for “that significant period when the wind turbines are not working”, and that “benefits of the supposedly ‘clean’ energy produced by wind turbines are likely to be more than offset by the dirty and inefficient energy produced by their essential diesel back-up”, all of which are outrageously deliberate misinterpretations of the facts :-

    http://www.dailymail.co.uk/news/article-2362762/The-dirty-secret-Britains-power-madness-Polluting-diesel-generators-built-secret-foreign-companies-kick-theres-wind-turbines–insane-true-eco-scandals.html
    “The dirty secret of Britain’s power madness: Polluting diesel generators built in secret by foreign companies to kick in when there’s no wind for turbines – and other insane but true eco-scandals : By James Dellingpole : PUBLISHED: 00:27, 14 July 2013″

    If “Dellingpole” and his compadre in what appear to be slurs, Richard North, were to ever do any proper research into the workings of the National Grid, they would easily uncover that the STOR is a very much transparent, publicly-declared utility :-

    http://www.nationalgrid.com/uk/Electricity/Balancing/services/balanceserv/reserve_serv/stor/

    STOR is not news. Neither is the need for it to be beefed up. The National Grid will lose a number of electricity generation facilities over the next few years, and because of the general state of the economy (and resistance to wind power and solar power from unhelpful folk like “Dellingpole”) investment in true renewables will not entirely cover this shortfall.

    Renewable energy is intermittent and variable. If an anticyclone high pressure weather system sits over Britain, there could be little wind. And if the sky is cloudy, there could be much less sun than normal. More renewable power feeding the grid means more opportunities when these breaks in service amount to something serious.

    Plus, the age of other electricity generation plants means that the risk of “unplanned outage”, from a nuclear reactor, say, is getting higher. There is a higher probability of sudden step changes in power available from any generator.

    The gap between maximum power demand and guaranteed maximum power generation is narrowing. In addition, the threat of sudden changes in output supply is increasing.

    With more generation being directly dependent on weather conditions and the time of day, and with fears about the reliability of ageing infrastructure, there is a need for more very short term immediate generation backup to take up the slack. This is where STOR comes in.

    Why does STOR need to exist ? The answer’s in the name – for short term balancing issues in the grid. Diesel generation is certainly not intended for use for long periods. Because of air quality issues. Because of climate change issues. Because of cost.

    If the Meteorological Office were to forecast a period of low wind and low incident solar radiation, or a nuclear reactor started to dip in power output, then the National Grid could take an old gas plant (or even an old coal plant) out of mothballs, pull off the dust sheets and crank it into action for a couple of days. That wouldn’t happen very often, and there would be time to notify and react.

    But if a windfarm suddenly went into the doldrums, or a nuclear reactor had to do an emergency shutdown, there would be few power stations on standby that could respond immediately, because it takes a lot of money to keep a power plant “spinning”, ready to use at a moment’s notice.

    So, Delingpole, there’s no conspiracy. There’s engagement with generators to set up a “first responder” network of extra generation capacity for the grid. This is an entirely public process. It’s intended for short bursts of immediately-required power because you can’t seem to turn your air conditioner off. The cost and emissions will be kept to a minimum. You’re wrong. You’re just full of a lot of hot air.

  • Battle of the Lords

    Posted on July 12th, 2013 Jo 1 comment

    I don’t quite know what powers Lord Deben, John Gummer, but he looks remarkably wired on it. At this week’s PRASEG Annual Conference, he positively glowed with fervour and gumption. He regaled us with tales of debate in the House of Lords, the UK’s parliamentary “senior” chamber. He is a known climate change science adherent, and in speaking to PRASEG, he was preaching to the choir, but boy, did he give a bone-rattling homily !

    As Chairman of the Committee on Climate Change, he is fighting the good fight for carbon targets to be established in all areas of legislation, especially the in-progress Energy Bill. He makes the case that emissions restraint and constraint is now an international business value, and of importance to infrastructure investment :-

    “The trouble with energy efficiency is that it’s not “boys’ toys” – there’s no “sex” in it. It is many small things put together to make a big thing. We won’t get to a point of decarbonisation unless we [continuously] make [the case for] [continuous] investment. [...] GLOBE [of which I am a member] in a report – 33 major countries – doing so much. [...] Look at what China is doing. Now a competitive world. If we want people to come here and invest, we need to have a carbon intensity target in 2030 [which will impact] [manufacturing] and the supply chain. [With the current strategy, the carbon targets are] put down in 2020 and picked up again in 2050. Too long a gap for business. They don’t know what happens in between. This is not all about climate change. It is about UK plc.”

    To supplement this diet of upbeat encouragement, he added a good dose of scorn for fellow Lords of the House, the Lords Lawson (Nigel Lawson) and Lord Ridley (Matt Ridley) who, he seemed to be suggesting, clearly have not mastered the science of climate change, and who, I believe he imputed, have lost their marbles :-

    “Apart from one or two necessary sideswipes, I agree with the previous speaker. There is no need for disagreement except for those who dismiss climate change. [I call them "dismissers" as we should not] dignify their position by calling them “sceptics”. We are the sceptics. We come to a conclusion based on science and we revisit it every time new science comes our way. They rifle through every [paper] to find every little bit that suppports their argument. I’ve listened to the interventions [in the House of Lords reading of and debate on the Energy Bill] of that group. Their line is the Earth is not [really] warming, so, it’s too expensive to do anything. This conflicts with today’s World Meteorological Organization measurements – that the last decade has been the warmest ever. I bet you that none of them [Lords] will stand up [in the House of Lords] and say “Sorry. We got it wrong.” They pick one set of statistics and ignore the rest. It is a concentrated effort to undermine by creating doubt. Our job is constantly to make it clear they we don’t need to argue the case – the very best science makes it certain [but never absolute]. You would be very foolish to ignore the consensus of view. [...] In a serious grown-up world, we accept the best advice – always keeping an eye out for new information. Otherwise, [you would] make decisions on worst information – no sane person does that.”

    He encouraged us to encourage the dissenters on climate change science to view the green economy as an insurance policy :-

    “Is there a householder here who does not insure their houses against fire ? You have a 98% change of not having a fire. Yet you spend on average £140 a year on insurance. Because of the size of the disaster – the enormity of the [potential] loss. Basic life-supporting insurance. I’m asking for half of that. If only Lord Lawson would listen to the facts instead of that Doctor of Sports Science, Benny Peiser. Or Matt Ridley – an expert in the sexual habits of pheasants. If I want to know about pheasants, I will first ask Lord Ridley. Can he understand why I go to a climatologist first ? [To accept his view of the] risks effects of climate change means relying on the infallibility of Lord Lawson [...]”

    He spoke of cross-party unity over the signing into law of the Climate Change Act, and the strength of purpose within Parliament to do the right thing on carbon. He admitted that there were elements of the media and establishment who were belligerently or obfuscatingly opposing the right thing to do :-

    “[We] can only win if the world outside has certainty about institutional government. This is a battle we have taken on and won’t stop till we win it. [The Lord Lawson and Lord Ridley and their position is] contrary to science, contrary to sense and contrary to the principle of insurance. They will not be listened to, not now, until UK has reduced level of carbon emissions, and we have [promised] our grandchildren they they are safe from climate change.”

    Phew ! That was a war cry, if ever there was one ! We are clearly in the Salvation Army ! I noted the attendance list, that showed several Gentlemen and Ladies of the Press should have been present, and hope to read good reports, but know that in some parts of the Gutter, anti-science faecal detritus still swirls. We in One Birdcage Walk were the assembly of believers, but the general public conversation on carbon is poisoned with sulphurous intent.

  • Hadeo- and Archaeo-Geobiology

    Posted on July 8th, 2013 Jo No comments

    What can deep time teach us ?

    Whilst doing a little background research into biological routes to hydrogen production, I came across a scientific journal paper, I can’t recall which, that suggested that the geological evidence indicates that Earth’s second atmosphere not only had a high concentration of methane, but also high levels of hydrogen gas.

    Previously, my understanding was that the development of microbiological life included a good number of methanogens (micro-life that produces methane as a waste product) and methanotrophs (those that “trough” on methane), but that hydrogenogen (“respiring” hydrogen gas) and hydrogenotroph (metabolising hydrogen) species were a minority, and that this was reflected in modern-day decomposition, such as the cultures used in biogas plants for anaerobic digestion.

    If there were high densities of hydrogen cycle lifeforms in the early Earth, maybe there are remnants, descendants of this branch of the tree of life, optimal at producing hydrogen gas as a by-product, which could be employed for biohydrogen production, but which haven’t yet been scoped.

    After all, it has only been very recently that psychrophiles have been added to the range of microorganisms that have been found useful in biogas production – cold-loving, permafrost-living bugs to complement the thermophile and mesophile species.

    Since hydrogen and methane are both ideal gas fuels, for a variety of reasons, including gas storage, combustion profiles and simple chemistry, I decided I needed to learn a little more.

    I have now read a plethora of new theories and several books about the formation of the Earth (and the Moon) in the Hadean Eon, the development of Earth’s atmosphere, the development of life in the Archaean Eon, and the evolution of life caused by climate change, and these developments in living beings causing climate change in their turn.

    Most of this knowledge is mediated to us by geology, and geobiology. But right at its heart is catalytic chemistry, once again. Here’s Robert Hazen (Robert M. Hazen) from page 138 of “The Story of Earth” :-

    “Amino acids, sugars, and the components of DNA and RNA adsorb onto all of Earth’s most common rock-forming minerals [...] We concluded that wherever the prebiotic ocean contacted minerals, highly concentrated arrangements of life’s molecules are likely to have emerged from the formless broth [...] Many other researchers have also settled on such a conclusion – indeed, more than a few prominent biologists have also gravitated to minerals, because origins-of-life scenarios that involve only oceans and atmosphere face insurmountable problems in accounting for efficient mechanisms of molecular selection and concentration. Solid minerals have an unmatched potential to select, concentrate, and organize molecules. So minerals much have played a central role in life’s origins. Biochemistry is complex, with interwoven cycles and networks of molecular reactions. For those intricately layered processes to work, molecules have to have just the right sizes and shapes. Molecular selection is the task of finding the best molecule for each biochemical job, and template-directed selection on mineral surfaces is now the leading candidate for how nature did it [...] left- and right-handed molecules [...] It turns out that life is incredibly picky : cells almost exclusively employ left-handed amino acids and right-handed sugars. Chirality matters [...] Our recent experiments have explored the possibility that chiral mineral surfaces played the starring role in selecting handed molecules, and perhaps the origins of life as well. [...] Our experiments showed that certain left-handed molecules can aggregate on one set of crystal surfaces, while the mirror image [...] on other sets [...] As handed molecules are separated and concentrated, each surface becomes a tiny experiment in molecular selection and organization. On its own, no such natural experiment with minerals and molecules is likely to have generated life. But take countless trillions of trillions of trillions of mineral surfaces, each bathed in molecule-rich organic broth [...] The tiny fraction of all those molecular combinations that wound up displaying easier self-assembly, or developed a stronger binding to mineral surfaces [...] survived [...] possibly to learn new tricks.”

  • They Think It’s Not All Over

    So, the EIA say that the world has 10 years of shale oil resources which are technically recoverable. Woo hoo. We’ll pass over the question of why the American Department of Energy are guiding global energy policy, and why this glowing pronouncement looks just like the mass propaganda exercise for shale gas assessments that kicked off a few years ago, and move swiftly on to the numbers.

    No, actually, not straight on to the numbers. It shouldn’t take a genius to work out the public relations strategy for promoting increasingly dirtier fossil fuels. First, they got us accustomed to the idea of shale gas, and claimed without much evidence, that it was as “clean” as Natural Gas, and far, far cleaner than coal. Data that challenges this myth continues to be collected. Meanwhile, now we are habituated to accepting without reason the risks of subsurface and ground water reservoir destruction by hydraulic fracturing, we should be pliable enough to accept the next step up – oil shale oil fracking. And then the sales team can move on to warm us up to cruddier unconventionals, like bitumen exhumed from tar sands, and mining unstable sub-sea clathrates.

    Why do the oil and gas companies of the world and their trusted allies in the government energy departments so desperately want us to believe in the saving power of shale oil and gas ? Why is it necessary for them to pursue such an environmentally threatening course of product development ? Can it be that the leaders of the developed world and their industry experts recognise, but don’t want to admit to, Peak Oil, and its twin wraith, Peak Natural Gas, that will shadow it by about 10 to 15 years ?

    A little local context – UK oil production is falling like a stoneover the whole North Sea area. Various efforts have been made to stimulate new investment in exploration and discovery. The overall plan for the UK Continental Shelf has included opening up prospects via licence to smaller players in the hope of getting them to bet the farm, and if they come up trumps, permitted the larger oil and gas companies to snaffle up the small fry.

    But really, the flow of Brent crude oil is getting more expensive to guarantee. And it’s not just the North Sea – the inverse pyramid of the global oil futures market is teeteringly wobbly, even though Natural Gas Liquids (NGL) are now included in petroleum oil production figures. Cue panic stations at the Coalition (Oilition) Government offices – frantic rustling of review papers ahoy.

    To help them believe it’s not all over, riding into view from the stables of Propaganda Central, come the Six Horsemen of Unconventional Fossil Fuels : Tar Sands, Shale Gas, Shale Oil (Oil Shale Oil), Underground Coal Gasification, Coalbed Methane and Methane Hydrates.

    Shiny, happy projections of technically recoverable unconventional (night)mares are always lumped together, like we are able to suddenly open up the ground and it starts pouring out hydrocarbon goodies at industrial scale volumes. But no. All fossil fuel development is gradual – especially at the start of going after a particular resource. In the past, sometimes things started gushing or venting, but those days are gone. And any kind of natural pump out of the lithosphere is entirely absent for unconventional fossil fuels – it all takes energy and equipment to extract.

    And so we can expect trickles, not floods. So, will this prevent field depletion in any region ? No. It’s not going to put off Peak Oil and Peak Natural Gas – it literally cannot be mined fast enough. Even if there are 10 years of current oil production volumes that can be exploited via mining oil shale, it will come in dribs and drabs, maybe over the course of 50 to 100 years. It might prolong the Peak Oil plateau by a year or so – that’s barely a ripple. Unconventional gas might be more useful, but even this cannot delay the inevitable. For example, despite the USA shale gas “miracle”, as the country continues to pour resources and effort into industrialising public lands, American Peak Natural Gas is still likely to be only 5 years, or possibly scraping 10 years, behind Global Peak Natural Gas which will bite at approximately 2030 or 2035-ish. I suspect this is why EIA charts of future gas production never go out beyond 2045 or so :-

    Ask a mathematician to model growth in unconventional fossil fuels compared to the anticipated and actual decline in “traditional” fossil fuels, and ask if unconventionals will compensate. They will not.

    The practice for oil and gas companies is to try to maintain shareholder confidence by making sure they have a minimum of 10 years of what is known as Reserves-to-Production ratio or R/P. By showing they have at least a decade of discovered resources, they can sell their business as a viable investment. Announcing that the world has 10 years of shale oil it can exploit sounds like a healthy R/P, but in actual fact, there is no way this can be recovered in that time window. The very way that this story has been packaged suggests that we are being encouraged to believe that the fossil fuel industry are a healthy economic sector. Yet it is so facile to debunk that perspective.

    People, it’s time to divest your portfolios of oil and gas concerns. If they have to start selling us the wonders of bitumen and kerogen, the closing curtain cannot be far away from dropping.

    They think it’s not all over, but it so clearly must be.

  • Renewable Gas : Research Parameters

    Posted on May 25th, 2013 Jo No comments

    “So what do you do ?” is a question I quite frequently have to answer, as I meet a lot of new people, in a lot of new audiences and settings, on a regular basis, as an integral part of my personal process of discovery.

    My internal autocue answer has modified, evolved, over the years, but currently sounds a lot like this, “I have a couple of part-time jobs, office administration, really. I do a spot of weblogging in my spare time. But I’m also doing some research into the potential for Renewable Gas.” I then pause for roughly two seconds. “Renewable Gas ?” comes back the question.

    “Yes,” I affirm in the positive, “Industrial-scale chemistry to produce gas fuels not dug up out of the ground. It is useful to plug the gaps in Renewable Electricity when the sun isn’t shining and the wind isn’t blowing.”

    It’s not exactly an elevator pitch – I’m not really selling anything except a slight shift in the paradigm here. Renewable Energy. Renewable Electricity. Renewable Gas. Power and gas. Gas and power. It’s logical to want both to be as renewable and sustainable and as low carbon as possible.

    Wait another two seconds. “…What, you mean, like Biogas ?” comes the question. “Well, yes, and also high volumes of non-biological gas that’s produced above the ground instead of from fossil fuels.”

    The introductory chat normally fades after this exchange, as my respondent usually doesn’t have the necessary knowledge architecture to be able to make any sense of what my words represent. I think it’s fair to say I don’t win many chummy friends paradigm-bumping in this way, and some probably think I’m off the deep end psychologically, but hey, evolutionaries don’t ever have it easy.

    And I also find that it’s not easy to find a place in the hierarchy of established learning for my particular “research problem”. Which school could I possibly join ? Which research council would adopt me ?

    The first barrier to academic inclusion is that my research interest is clearly motivated by my concern about the risks of Climate Change – the degradation in the Earth’s life support systems from pumping unnaturally high volumes of carbon dioxide into the air – and Peak Fossil Fuels – the risks to humanity from a failure to grow subsurface energy production.

    My research is therefore “applied” research, according to the OECD definition (OECD, 2002). It’s not motivated simply by the desire to know new things – it is not “pure” research – it has an end game in mind. My research is being done in order to answer a practical problem – how to decarbonise gaseous, gas phase, energy fuel production.

    The second barrier to the ivory tower world that I have is that I do not have a technological contribution to make with this research. I am not inventing a chemical process that can “revolutionise” low carbon energy production. (I don’t believe in “revolutions” anyway. Nothing good ever happens by violent overthrow.) My research is not at the workbench end of engineering, so I am not going to work amongst a team of industrial technicians, so I am not going to produce a patent for clean energy that could save the world (or the economy).

    My research is more about observing and reporting the advances of others, and how these pieces add up to a journey of significant change in the energy sector. I want to join the dots from studies at the leading edge of research, showing how this demonstrates widespread aspiration for clean energy, and document instances of new energy technology, systems and infrastructure. I want to witness to the internal motivation of thousands of people working with the goal of clean energy across a very wide range of disciplines.

    This is positively positive; positivity, but it’s not positivism – it’s not pure, basic research. This piece of research could well influence people and events – it’s certainly already influencing me. It’s not hands-off neutral science. It interacts with its subjects. It intentionally intervenes.

    Since I don’t have an actual physical contribution or product to offer, and since I fully expect it to “interfere” with current dogma and political realities, what I am doing will be hard to acknowledge.

    This is not a PhD. But it is still a piece of philosophy, the love of wisdom that comes from the acquisition of knowledge.

    I have been clear for some time about what I should be studying. Call it “internal drive” if you like. The aim is to support the development of universal renewable energy as a response to the risks of climate change and peak fossil fuel energy production. That makes me automatically biased. I view my research subject through the prism of hope. But I would contend that this is a perfectly valid belief, as I already know some of what is possible. I’m not starting from a foundational blank slate – many Renewable Gas processes are already in use throughout industry and the energy sector. The fascinating part is watching these functions coalesce into a coherent alternative to the mining of fossil fuels. For the internal industry energy production conversation is changing its track, its tune.

    For a while now, “alternative” energy has been a minor vibration, a harmonic, accentuating the fossil fuel melody. As soon as the mid-noughties economic difficulties began to bite, greenwash activities were ditched, as oil and gas companies resorted to their core business. But the “green shoots” of green energy are still there, and every now and then, it is possible to see them poking up above the oilspill-desecrated soil. My role is to count blades and project bushes. Therefore my research is interpretivist or constructivist, although it is documenting positivist engineering progress. That’s quite hard for me to agree with, even though I reasoned it myself. I can still resist being labelled “post-positivist”, though, because I’m still interpreting reality not relativisms.

    So now, on from research paradigm to research methodologies. I was trained to be an experimentalist scientist, so this is a departure for me. In this case, I am not going to seek to make a physical contribution to the field by being actively involved as an engineer in a research programme, partly because from what I’ve read so far, most of the potential is already documented and scoped.

    I am going to use sociological methods, combining observation and rapportage, to and from various organisations through various media. Since I am involved in the narrative through my interactions with others, and I influence the outcomes of my research, this is partly auto-narrative, autoethnographic, ethnographic. An apt form for the research documentation is a weblog, as it is a longitudinal study, so discrete reports at time intervals are appropriate. Social media will be useful for joining the research to a potential audience, and Twitter has the kind of immediacy I prefer.

    My observation will therefore be akin to journalism – engineering journalism, where the term “engineering” covers both technological and sociological aspects of change. A kind of energy futures “travelogue”, an observer of an emerging reality.

    My research methods will include reading the science and interacting with engineers. I hope to do a study trip (or two) as a way of embedding myself into the new energy sector, with the explicit intention of ensuring I am not purely a commentator-observer. My research documentation will include a slow collation of my sources and references – a literature review that evolves over time.

    My personal contribution will be slight, but hopefully set archaic and inefficient proposals for energy development based on “traditional” answers (such as nuclear power, “unconventional” fossil fuel production and Carbon Capture and Storage for coal) in high relief.

    My research choices as they currently stand :-

    1. I do not think I want to join an academic group.

    2. I do not think I want to work for an energy engineering company.

    3. I do not want to claim a discovery in an experimental sense. Indeed, I do not need to, as I am documenting discoveries and experiments.

    4. I want to be clear about my bias towards promoting 100% renewable energy, as a desirable ambition, in response to the risks posed by climate change and peak fossil fuel production.

    5. I need to admit that my research may influence outcomes, and so is applied rather than basic (Roll-Hansen, 2009).

  • Natural Gas in the UK

    Posted on February 27th, 2013 Jo No comments

    The contribution of coal-fired power generation to the UK’s domestic electrical energy supply appears to have increased recently, according to the December 2012 “Energy Trends” released by the Department of Energy and Climate Change. This is most likely due to coal plants using up their remaining allotted operational hours until they need to retire.
    It could also be due to a quirk of the international markets – coal availability has increased because of gas glut conditions in the USA leading to higher coal exports. Combatting the use of coal in power generation is a global struggle that still needs to be won, but in the UK, it is planned that low carbon generation will begin to gain ascendance.

    The transition to lower carbon energy in Britain relies on getting the Natural Gas strategy right. With the imminent closure of coal-fired power plant, the probable decommissioning of several nuclear reactors, and the small tranche of overall supply coming from renewable resources, Natural Gas needs to be providing a greater overall percentage of electricity in the grid. But an increasing amount of this will be imported, since indigenous production is dropping, and this is putting the UK’s economy at risk of high prices and gas scarcity.

    Demand for electricity for the most part changes by a few percentage points a year, but the overall trend is to creep upwards (see Chart 4, here). People have made changes to their lighting power consumption, but this has been compensated for by an increase in power used by “gadgets” (see Chart 4, here). There is not much that can be done to suppress power consumption. Since power generation must increasingly coming from renewable resources and Natural Gas combustion, this implies strong competition between the demand for gas for heating and the demand gas for electricity. Electricity generation is key to the economy, so the power sector will win any competition for gas supplies. If competition for Natural Gas is strong, and since we don’t have much national gas storage, we can expect higher seasonal imports and therefore, higher prices.

    It is clear that improving building insulation across the board is critical in avoiding energy insecurity. I shall be checking the winter heat demand figures assiduously from now on, to determine if the Green Deal and related measures are working. If they don’t, the UK is in for heightened energy security risks, higher carbon emissions, and possibly much higher energy prices. The Green Deal simply has to work.
