It’s clear to me that the near-term and mid-term future for energy in the United Kingdom and the European Union will best be centred on Natural Gas and Renewable Electricity, and now the UK Energy Research Centre has modelled essentially the same scenario. This can become a common narrative amongst all parties – the policy people, the economists, the technologists, the non-governmental groups, as long as some key long-term de-carbonisation and energy security objectives are built into the plan.
The researchers wanted to emphasise from their report that the use of Natural Gas should not be a default option in the case that other strategies fail – they want to see a planned transition to a de-carbonised energy system using Natural Gas by design, as a bridge in that transition. Most of the people in the room found they could largely agree with this. Me, too. My only caveat was that when the researchers spoke about Gas-CCS – Natural Gas-fired power generation with Carbon Capture and Storage attached, my choice would be Gas-CCU – Natural Gas-fired power generation with Carbon Capture and Re-utilisation – carbon recycling – which will eventually lead to much lower emissions gas supply at source.
What follows is a transcription of my poorly-written notes at the meeting, so you cannot accept them as verbatim.

[JW] Thanks to Matt Aylott. Live Tweeting #FutureOfGas. Clearly gas is very very important. It’s never out of the news. The media all want to talk about fracking… If we want to meet the 2 degrees Celsius target of the United Nations Framework Convention on Climate Change, how much can gas be a part of this ? Is Natural Gas a bridge – how long a ride will that gas bridge be ?
[CM] Gas as a bridge ? There is healthy debate about the Natural Gas contribution to climate change [via the carbon dioxide emissions from burning Natural Gas, and also about how much less in emissions there is from burning Natural Gas compared to burning coal]. The IPCC said that “fuel switching” from coal to gas would offer emissions benefits, but some research, notably McJeon et al. (2014) made statements that switching to Natural Gas cannot confer emissions benefits. Until recently, there have not been many disaggregated assessments on gas as a bridge. We have used TIAM-UCL. The world is divided into 16 regions. The “climate module” seeks to constrain the global temperature rise to 2 degrees Celsius. One of the outcomes from our model was that export volumes [from all countries] would be severaly impacted by maintaining the price indexation between oil and gas. [Reading from chart on the screen : exports would peak in 2040s]. Another outcome was that gas consumption is not radically affected by different gas market structures. However, the over indexation to the oil price may destroy gas export markets. Total exports of natural gas are higher under the 2 degrees Celsius scenario compared to the 4 degrees Celsius scenario – particularly LNG [Liquefied Natural Gas]. A global climate deal will support gas exports. There will be a higher gas consumption under a 2 degrees Celsius deal compared to unconstrained scenario [leading to a 4 degrees Celsius global temperature rise]. The results of our modelling indicate that gas acts as a bridge fuel out to 2035 [?] in both absolute and relative terms. There is 15% greater gas consumption in the 2 degrees Celsius global warming scenario than in the 4 degrees Celsius global warming scenario. Part of the reason is that under the 4 degrees Celsius scenario, Compressed Natural Gas vehicles are popular, but a lot less useful under the 2 degrees Celsius scenario [where hydrogen and other fuels are brought into play].
There are multiple caveats on these outcomes. The bridging period is strictly time-limited. Some sectors need to sharply reduce consumption [such as building heating by Natural Gas boilers, which can be achieved by mass insulation projects]. Coal must be curtailed, but coal-for-gas substitution alone is not sufficient. Need a convincing narrative about how coal can be curtailed. In an absence of a global binding climate deal we will get consumption increases in both coal and gas. In the model, gas is offsetting 15% of coal by 2020, and 85% by 2030. With Carbon Capture and Storage (CCS), gas’s role is drastically reduced – after 2025 dropping by 2% a year [of permitted gas use]. Not all regions of the world can use gas as a bridge. [Reading from the chart : with CCS, gas is a strong bridging fuel in the China, EU, India, Japan and South Korea regions, but without CCS, gas is only strong in China. With CCS, gas’s bridging role is good in Australasia, ODA presumably “Offical Development Assistance” countries and USA. Without CCS, gas is good for Africa, Australasia, EU, India, Japan, South Korea, ODA and USA.]
In the UK, despite the current reliance on coal, there is little scope to use it as a transition fuel. Gas is unlikely to be removed from UK energy system by 2050.
[Question from the floor] The logic of gas price indexation with the oil price ?
[CM] If maintain oil indexation, exports will reduce as countries turn more towards indigenous at-home production of gas for their domestic demand. This would not be completely counter-balanced by higher oil and therefore gas prices, which should stimulate more exports.
[Point from the floor] This assumes logical behaviour…
[Question from the floor] [Question about Carbon Capture and Storage (CCS)]
[CM] The model does anticipate more CCS – which permits some extra coal consumption [at the end of the modelling period]. Gas-CCS [gas-fired power generation with CCS attached] is always going to generate less emissions than coal-CCS [coal-fired power generation with CCS attached] – so the model prefers gas-CCS.
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 ?
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.
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].
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.
Sigh. I think I’m going to need to start sending out Freedom of Information requests… Several cups of tea later…

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.
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…”
“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 !”

Subject: Question from your TED talk
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.

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) :-
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.
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.
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 ?
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.

subject: Question from your TED talk
Dear [Professor] Sears,
I was intrigued by your TED talk that I recently viewed :-
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 ?

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.

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 ?

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.
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.
In the matter of the BBC and balance in the reporting of Climate Change, I believe they might have lost their perch. Admittedly, it wasn’t a very large perch – and some were swaying in any breeze that came along. But to invite one of the fringiest of the fringe of science “sceptics” onto a Radio 4 broadcast on the day of the publication of the Intergovernmental Panel on Climate Change Fifth Assessment Report Working Group 1 demonstrates that the BBC policy on achieving a suitable, accurate and appropriate fulcrum in the balance of science reporting is an ex-policy, a former policy, gone and pushing up the Cleeseian daisies.
Citizens have been piqued, annoyed, needled, frustrated, despairing and, frankly, appalled, and some measures have been taken to remonstrate with the BBC. One such is below. Dear Reader, your comments on the subject of media balance are welcome, unless of course you haven’t read any Climate Change science and think it’s all a hoax, that the scientists are lying, and the Earth’s climate has always gone in similar cycles to the current warming, think that Global Warming is undergoing a “pause” etc etc – because you’re wrong. Plain and simple. If you don’t accept Climate Change science, if you haven’t read any of the relevant research papers, if you haven’t taken the trouble to understand what it’s all about, you are likely to be a clanging gong, a thorn in the side, and your views may well signify nothing, and certainly shouldn’t be aired in a public broadcast without challenge.
It is time for the BBC to stop inviting Climate Change science “sceptics” – no, “deniers” onto their programmes. Once and for all. I mean, to go all Godwin on you, the BBC wouldn’t invite Adolf Hitler onto their shows to comment about the contribution that Judaism has brought to humanity, or to deny the Holocaust ? And they wouldn’t invite the CEO of a cigarette manufacture company on to insist that smoking doesn’t cause lung cancer, would they ? There is a bar, a standard, to which the BBC should aspire, on science reporting, and I feel that in this case they slid disgracefully under it and landed in a stinky puddle of failure on the studio floor. The programme editors should be ashamed, in my honest opinion.
Open letter to Tony Hall, Lord Hall of Birkenhead and Director General of the BBC, on the platform given to Prof Bob Carter on the World at One programme (Fri 27th Sept 2013)
Dear Lord Hall,
We, the undersigned scientists and engineers, write to condemn the appearance of Prof Bob Carter on BBC Radio 4’s World at One programme, and to urge the BBC to seriously rethink the treatment given to climate change in its factual programming, and particularly its coverage of the Intergovernmental Panel on Climate Change’s Fifth Assessment Report.
The BBC, uniquely amongst broadcasters, has a public duty to provide a balanced coverage of news across its media channels, yet when it comes to its coverage of climate change it has frequently failed to do so. Furthermore, the BBC’s status as a trusted source of news means that damage done by its biased reporting of the overwhelming evidence of the certainty and significance of man-made climate change is inexorably greater. Not only does this damage public trust in climate science, but it also damages public trust in scientific evidence in general. This assertion is even supported by the BBC’s own surveys on public attitudes to climate change.
The IPPC’s Assessment Reports represent the consensus of evidence and opinion from thousands of scientists and engineers around the world, working in all of the many fields encompassed by climate change. That consensus is overwhelmingly of the view that the evidence that human activities are driving changes in our climate at an unprecedented rate and scale – there is no ‘climate debate’ in the scientific community.
The appearance of Prof Carter on the World at One, and that of climate change deniers on other BBC programmes, is the equivalent of giving a stork the right to reply on every appearance by Prof Robert Winston. Prof Carter is a geologist who speaks for the “Nongovernmental International Panel on Climate Change”, or NIPCC, a name which non-experts could be forgiven for confusing with the IPCC, however Prof Carter is not a climate scientist and the NIPCC is not the IPCC.
Indeed, had the editors of the World at One bothered to check the credentials of the NIPCC they would have realised that far from being an independent organisation, it is backed by the Heartland Institute, a US-based free-market thinktank that opposes urgent action on climate change, which is itself opaquely funded by ‘family foundations’ suspected of having significant vested interests in undermining climate science. To return to the analogy, that stork would be funded by the Discovery Institute.
For climate scientists, and those of us working in related fields, it is hard enough to accept that the BBC is required to give a platform to politicians whose lack of knowledge of climate science is matched only by their unwillingness to ‘use sound science responsibly’. When the Environment Secretary Owen Paterson describes climate change as “not all bad” he may be committing an abuse of the evidence and his position, but he at least does so with the rights and responsibilities of a democratically elected Member of Parliament. However when deniers such as Prof Carter use the media to argue that the scientific consensus on climate change is anything but overwhelming, the evidence on which they claim to be basing their arguments, and their sources of funding, are frequently left unrevealed and unquestioned.
It is therefore hardly surprising that the BBC and other media outlets sometimes struggle to find climate scientists willing to speak to them, and by providing a platform for Prof Cater and other deniers the BBC is also complicit in engendering the environment in which climate scientists are often reluctant to speak to the media.
The BBC should now issue an explanation for the appearance of Prof Carter and the treatment given to his opinions on a flagship news programme. Furthermore, it should urgently review the treatment of climate change across all of its outputs, and require full disclosures of any and all vested interests held by commentators on the subject. Finally, it should also ensure that the editorial boards covering all its scientific outputs include members with appropriate scientific backgrounds who are able to give independent advice on the subject matter, and that their advice is recorded and adhered to.

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 :-
“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 :-
“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.”
“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 :-
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
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].
This week, both Caroline Flint MP and Ed Balls MP have publicly repeated the commitment by the UK’s Labour Party to a total decarbonisation of the power sector by 2030, should they become the governing political party. At PRASEG’s Annual Conference, Caroline Flint said “In around ten years time, a quarter of our power supply will be shut down. Decisions made in the next few years […] consequences will last for decades […] keeping the lights on, and [ensuring reasonably priced] energy bills, and preventing dangerous climate change. […] Labour will have as an election [promise] a legally binding target for 2030. […] This Government has no vision.”
And when I was in an informal conversation group with Ed Davey MP and Professor Mayer Hillman of the Policy Studies Institute at a drinks reception after the event hosted by PRASEG, the Secretary of State for Energy and Climate Change seemed to me to also be clear on his personal position backing the 2030 “decarb” target.
Ed Davey showed concern about the work necessary to get a Europe-wide commitment on Energy and Climate Change. He took Professor Hillman’s point that carbon dioxide emissions from the burning of fossil fuels are already causing dangerous climate change, and that the risks are increasing. However, he doubted that immediate responses can be made. He gave the impression that he singled out Poland of all the countries in the European Union to be an annoyance, standing in the way of success. He suggested that if Professor Hillman wanted to do something helpful, he could fly to Poland…at this point Professor Hillman interjected to say he hasn’t taken a flight in 70 years and doesn’t intend to now…and Ed Davey continued that if the Professor wanted to make a valuable contribution, he could travel to Poland, taking a train, or…”I don’t care how you get there”, but go to Poland and persuade the Poles to sign up to the 2030 ambition.
Clearly, machinations are already afoot. At the PRASEG Annual Conference were a number of communications professionals, tightly linked to the debate on the progress of national energy policy. Plus, one rather exceedingly highly-networked individual, David Andrews, the key driver behind the Claverton Energy Research Group forum, of which I am an occasional participant. He had ditched the normal navy blue polyester necktie and sombre suit for a shiveringly sharp and open-necked striped shirt, and was doing his best to look dapper, yet zoned. I found him talking to a communications professional, which didn’t surprise me. He asked how I was.
JA : “I think I need to find a new job.”
DA : “MI6 ?”
JA : “Too boring !”
What I really should have said was :-
JA : “Absolutely and seriously not ! Who’d want to keep State Secrets ? Too much travel and being nice to people who are nasty. And making unbelievable compromises. The excitement of privilege and access would wear off after about six minutes. Plus there’s the risk of ending up decomposing in something like a locked sports holdall in some strange bathroom in the semblance of a hostelry in a godforsaken infested hellhole in a desolate backwater like Cheltenham or Gloucester. Plus, I’d never keep track of all the narratives. Or the sliding door parallel lives. Besides, I’m a bit of a Marmite personality – you either like me or you really don’t : I respond poorly to orders, I’m not an arch-persuader and I’m not very diplomatic or patient (except with the genuinely unfortunate), and I’m well-known for leaping into spats. Call me awkward (and some do), but I think national security and genuine Zero Carbon prosperity can be assured by other means than dark arts and high stakes threats. I like the responsibility of deciding for myself what information should be broadcast in the better interests of the common good, and which held back for some time (for the truth will invariably out). And over and above all that, I’m a technologist, which means I prefer details over giving vague impressions. And I like genuine democratic processes, and am averse to social engineering. I am entirely unsuited to the work of a secret propaganda and diplomatic unit.”
I would be prepared to work for a UK or EU Parliamentary delegation to Poland, I guess, if I could be useful in assisting with dialogue, perhaps in the technical area. I do after all have several academic degrees pertinent to the questions of Energy and Climate Change.
But in a room full of politicians and communications experts, I felt a little like a fished fish. Here, then, is a demonstration. I was talking with Rhys Williams, the Coordinator of PRASEG, and telling him I’d met the wonderful Professor Geoff Williams, of Durham Univeristy, who has put together a system of organic light emitting diode (LED) lighting and a 3-D printed control unit, and, and, and Rhys actually yawned. He couldn’t contain it, it just kind of spilled out. I told myself : “It’s not me. It’s the subject matter”, and I promptly forgave him. Proof, though, of the threshold for things technical amongst Westminster fixers and shakers.
Poland. I mean, I know James Delingpole has been to Poland, and I thought at the time he was possibly going to interfere with the political process on climate change, or drum up support for shale gas. But I’m a Zero Carbon kind of actor. I don’t need to go far to start a dialogue with Poland by going to Poland – I have Poles living in my street, and I’m invited to all their barbecues. Maybe I should invite Professor Mayer Hillman to cycle over to Waltham Forest and address my near neighbours and their extended friendship circle on the importance of renewable energy and energy efficiency targets, and ask them to communicate with the folks back home with any form of influence.
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.
“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.”
