From my studies, I conclude that humanity will continue to use gas energy fuels for a long time to come.
In that case, we need to know how to burn it cleanly, so I am starting a new phase of research and publication on this topic – “Clean Burn”.
Anybody is welcome to comment, feedback, review and contribute. It will all be Open Access.
Here is a draft version of the Introduction and Objectives.
Once a year BP plc publishes their Statistical Review of World Energy, as they have done for 65 years, now. Recent editions have been digital and anodyne, with lots of mini-analyses and charts and positive messages about the petroleum industry. Whenever energy researchers ask questions, they are invariably directed to take a look at the BP report, as it is considered trustworthy and sound. Good scientists always try to find alternative sources of data, but it can be hard comparing the BP Stat Rev with other numerical offerings, partly because of the general lack of drill-down in-depth figures. Two other reputable data sources are the US Energy Information Administration (EIA) and the JODI Oil initiative. I have already looked at EIA data and data from the National Energy Board (NEB) of Canada recently in order to check on the risks of Peak Oil. Now I’m diving into JODI.
Two of my concerns of the week are to try to understand the status and health of the global economy – which can be seen through the lens of overall consumption of hydrocarbons; and to see if there are changes happening in relative demand levels for the different kinds of hydrocarbons – as this could indicate a transition towards a lower carbon economy. The BP Stat Rev of June 2016 offers an interesting table on Page 13 – “Oil: Regional consumption – by product group”, which breaks down hydrocarbon demand into four main categories : Light distillates, Middle distillates, Fuel oil and Other. The “Other” category for BP includes LPG – Liquefied Petroleum Gases, a blend of mostly propane and butanes (carbon chain C3 and C4), which are gaseous and not liquid at normal room temperature and pressure – so strictly speaking aren’t actually oil. They also have different sources from various process units within petroleum refinery and Natural Gas processing plants. The “Other” category also includes refinery gas – mostly methane and ethane (carbon chain C1 and C2), and hydrogen (H2); and presumably fuel additives and improvers made from otherwise unwanted gubbins at the petrorefinery.
Not by coincidence, the JODI Oil database, in its Secondary data table, also offers a breakdown of hydrocarbon demand from refinery into categories almost analagous to the BP groupings – LPG, Gasoline, Naphtha, Kerosenes, Gas/Diesel oil, Fuel oil, and Other products; where LPG added to Other should be the same as BP’s “Other” category, Gasoline added to Naphtha should be equivalent to BP’s “Light distillates”; and Kerosenes added to Gas/Diesel oil should be analagous to BP’s “Middle distillates. So I set out to average the JODI Oil data, day-weighting the monthly data records, to see if I could replicate the BP Stat Rev Page 13.
Very few of the data points matched BP’s report. I suspect this is partly due to averaging issues – I expect BP has access to daily demand figures, (although I can’t be sure, and I don’t know their data sources); whereas the JODI Oil data is presented as monthly averages for daily demand. However, there are a lot of figures in the BP report that are high compared to the JODI Oil database. This can only partly be due to the fact that not all countries are reporting to JODI – four countries in the Commonwealth of Indepdendent States (CIS) – formerly known as “Former Soviet Union” – are not reporting, for example. I’m wondering if this over-reporting in the BP report might be due to differences in the way that stock transfers are handled – perhaps demand for refinery products that are intended for storage purposes rather than direct consumption is included in the BP data, but not in JODI – but at the moment I don’t have any relevant information with which to confirm or deny this concept.
Anyway, the data is very close between BP and JODI for the United States in recent years, and there are some other lines where there is some agreement (for example – Fuel oil in Japan, and Light distillates in China), so I am going to take this as an indication that I understand the JODI Oil data sufficiently well to be able to look at monthly refinery demand, refinery output and oil production for each region and hopefully reach some useful conclusions.
Recently, I had a very helpful telephone conversation with somebody I shall call Ben – because that’s his name, obviously, so there’s no point in trying to camoflage that fact. It was a very positive conversation, with lots of personal energy from both parties – just the sort of constructive engagement I like.
Amongst a range of other things, we were batting about ideas for what could constitute a business model or economic case for the development of Renewable Gas production – whether Renewable Hydrogen or Renewable Methane. Our wander through the highways and byways of energy markets and energy policy led us to this sore point – that the National Grid is likely to resort to “fields of diesel generators” for some of its emergency backup for the power grid in the next few years – if new gas-fired power plants don’t get built. Various acronyms you might find in this space include STOR and BM.
Now, diesel is a very dirty fuel – so dirty that it appears to be impossible to build catalytic exhaust filters for diesel road vehicles that meet any of the air pollution standards and keep up fuel consumption performance. It’s not just VW that have had trouble meeting intention with faction – all vehicle manufacturers have difficulties balancing all the requirements demanded of them. Perhaps it’s time to admit that we need to ditch the diesel fuel itself, rather than vainly try to square the circle.
The last thing we really need is diesel being used as the fuel to prop up the thin margins in the power generation network – burned in essentially open cycle plant – incurring dirty emissions and a massive waste of heat energy. Maybe this is where the petrorefiners of Great Britain could provide a Renewable Gas alternative. Building new plant or reconfiguring existing plant for Renewable Gas production would obviously entail capital investment, which would create a premium price on initial operations. However, in the event of the National Grid requiring emergency electricity generation backup, the traded prices for that power would be high – which means that slightly more expensive Renewable Gas could find a niche use which didn’t undermine the normal economics of the market.
If there could be a policy mandate – a requirement that Renewable Gas is used in open cycle grid-balancing generation – for example when the wind dies down and the sun sets – then we could have fields of Renewable Gas generators and keep the overall grid carbon emissions lower than they would otherwise have been.
Both Ben and I enjoyed this concept and shared a cackle or two – a simple narrative that could be adopted very easily if the right people got it.
Renewable Gas – that’s the craic.
Status-checking questions. I’m sure we all have them. I certainly do. Several times a week, or even day, I ask myself two little questions of portent : “What am I doing ?” and “Why am I here ?”. I ask myself these questions usually because my mind’s wandered off again, just out of reach, and I need to call myself to attention, and focus. I ask these little questions of myself when I do that thing we all do – I’ve set off with great purpose into another room, and then completely forgotten why I went there, or what I came to find or get. I also use these forms of enquiry when I’m at The Crossroads of Purpose – to determine what exactly it is I’m deciding to aim for. What are my goals this day, week, month, age ? Can I espy my aims, somewhere on the horizon ? Can I paddle labouriously towards them – against the tide – dodge/defeat the sharks ? Can I muster the will to carry this out – “longhauling it” ?
I’ve spent a long time writing a book, which I’m sure to bore everybody about for the next aeon. My intention in writing the book was to stimulate debate about what I consider to be the best direction for balanced energy systems – a combination of renewable electricity and Renewable Gas. I wanted to foster debate amongst the academics and engineers who may be my peers, certainly, hopefully providing a little seed for further research. Hopefully also having a small influence on energy policy, perhaps, or at least, getting myself and my ideas asked to various policy meetings for a little airing. But, if I could in some way, I also wanted to offer a bit of fizz to the internal conversations of companies in the energy sector. You see, it may be obvious, or it may not be, but action on climate change, which principally involves the reduction in the mining, drilling and burning of fossil fuels, principally also involves the co-operation of the fossil fuel extraction companies. Their products are nearly history, and so it must be that inside the headquarters of every transnational energy giant, corporate heads are churning through their options with a very large what-if spoon.
So I met somebody last week, at their invitation, to talk a little bit about my research into Renewable Gas.
I can’t say who it was, as I didn’t get their permission to do so. I can probably (caveat emptor) safely say that they are a fairly significant player in the energy engineering sector.
I think they were trying to assess whether my work was a bankable asset yet, but I think they quickly realised that I am nowhere near a full proposal for a Renewable Gas system.
Although there were some technologies and options over which we had a meeting of minds, I was quite disappointed by their opinions in connection with a number of energy projects in the United Kingdom.
Out of the blue, I got an invitation to a meeting in Whitehall.
I was to join industrial developers and academic researchers at the Department of Energy and Climate Change (DECC) in a meeting of the “Green Hydrogen Standard Working Group”.
The date was 12th June 2015. The weather was sunny and hot and merited a fine Italian lemonade, fizzing with carbon dioxide. The venue was an air-conditioned grey bunker, but it wasn’t an unfriendly dungeon, particularly as I already knew about half the people in the room.
The subject of the get-together was Green Hydrogen, and the work of the group is to formulate a policy for a Green Hydrogen standard, navigating a number of issues, including the intersection with other policy, and drawing in a very wide range of chemical engineers in the private sector.
My reputation for not putting up with any piffle clearly preceded me, as somebody at the meeting said he expected I would be quite critical. I said that I would not be saying anything, but that I would be listening carefully. Having said I wouldn’t speak, I must admit I laughed at all the right places in the discussion, and wrote copious notes, and participated frequently in the way of non-verbal communication, so as usual, I was very present. At the end I was asked for my opinion about the group’s work and I was politely congratulational on progress.
So, good. I behaved myself. And I got invited back for the next meeting. But what was it all about ?
Most of what it is necessary to communicate is that at the current time, most hydrogen production is either accidental output from the chemical industry, or made from fossil fuels – the main two being coal and Natural Gas.
Hydrogen is used extensively in the petroleum refinery industry, but there are bold plans to bring hydrogen to transport mobility through a variety of applications, for example, hydrogen for fuel cell vehicles.
Clearly, the Green Hydrogen standard has to be such that it lowers the bar on carbon dioxide (CO2) emissions – and it could turn out that the consensus converges on any technologies that have a net CO2 emissions profile lower than steam methane reforming (SMR), or the steam reforming of methane (SRM), of Natural Gas.
[ It’s at this very moment that I need to point out the “acronym conflict” in the use of “SMR” – which is confusingly being also used for “Small Modular Reactors” of the nuclear fission kind. In the context of what I am writing here, though, it is used in the context of turning methane into syngas – a product high in hydrogen content. ]
Some numbers about Carbon Capture and Storage (CCS) used in the manufacture of hydrogen were presented in the meeting, including the impact this would have on CO2 emissions, and these were very intriguing.
I had some good and useful conversations with people before and after the meeting, and left thinking that this process is going to be very useful to engage with – a kind of dragnet pulling key players into low carbon gas production.
Here follow my notes from the meeting. They are, of course, not to be taken verbatim. I have permission to recount aspects of the discussion, in gist, as it was an industrial liaison group, not an internal DECC meeting. However, I should not say who said what, or which companies or organisations they are working with or for.
The British Government do not have an energy policy. They may think they have one, and they may regularly tell us that they have one, but in reality, they don’t. There are a number of elements of regulatory work and market intervention that they are engaged with, but none of these by itself is significant enough to count as a policy for energy. Moreover, all of these elements taken together do not add up to energy security, energy efficiency, decarbonisation and affordable energy.
What it takes to have an energy policy is a clear understanding of what is a realistic strategy for reinvestment in energy after the dry years of privatisation, and a focus on energy efficiency, and getting sufficient low carbon energy built to meet the Carbon Budget on time. Current British Government ambitions on energy are not realistic, will not attract sufficient investment, will not promote increased energy efficiency and will not achieve the right scale and speed of decarbonisation.
I’m going to break down my critique into a series of small chunks. The first one is a quick look at the numbers and outcomes arising from the British Government’s obsessive promotion of nuclear power, a fantasy science fiction that is out of reach, not least because the industry is dog-tired and motheaten.
Shell, BP and some of their confederates in the European oil and gas industry have inched, or perhaps “centimetred”, forward in their narrative on climate change. Previously, the major oil and gas companies were regularly outed as deniers of climate change science; either because of their own public statements, or because of secretive support of organisations active in denying climate change science. It does seem, finally, that Shell in particular has decided to drop this counter-productive “playing of both sides”. Not that there are any “sides” to climate change science. The science on climate change is unequivocal : changes are taking place across the world, and recent global warming is unprecedented, and has almost definitely been attributed to the burning of fossil fuels and land use change.
So Shell and BP have finally realised that they need to shed the mantle of subtle or not-so-subtle denial, although they cling to the shreds of dispute when they utter doubts about the actual numbers or impacts of global warming (for example : https://www.joabbess.com/2015/06/01/shells-public-relations-offensive/). However, we have to grant them a little leeway on that, because although petrogeologists need to understand the science of global warming in order to know where to prospect for oil and gas, their corporate superiors in the organisation may not be scientists at all, and have no understanding of the global carbon cycle and why it’s so disruptive to dig up all that oil and gas hydrocarbon and burn it into the sky. So we should cut the CEOs of Shell and BP a little slack on where they plump for in the spectrum of climate change narrative – from “utter outright doom” to “trifling perturbation”. The central point is that they have stopped denying climate change. In fact, they’re being open that climate change is happening. It’s a miracle ! They have seen the light !
But not that much light, though. Shell and BP’s former position of “scepticism” of the gravity and actuality of global warming and climate change was deployed to great effect in delaying any major change in their business strategies. Obviously, it would have been unseemly to attempt to transmogrify into renewable energy businesses, which is why anybody in the executive branches who showed signs of becoming pro-green has been shunted. There are a number of fairly decent scalps on the fortress pikes, much to their shame. Shell and BP have a continuing duty to their shareholders – to make a profit from selling dirt – and this has shelved any intention to transition to lower carbon energy producers. Granted, both Shell and BP have attempted to reform their internal businesses by applying an actual or virtual price on carbon dioxide emissions, and in some aspects have cleaned up and tidied up their mining and chemical processing. The worsening chemistry of the cheaper fossil fuel resources they have started to use has had implications on their own internal emissions control, but you have to give them credit for trying to do better than they used to do. However, despite their internal adjustments, their external-facing position of denial of the seriousness of climate change has supported them in delaying major change.
With these recent public admissions of accepting climate change as a fact (although CEOs without appropriate science degrees irritatingly disagree with some of the numbers on global warming), it seems possible that Shell and BP have moved from an outright “delay and deny” position, which is to be applauded.
However, they might have moved from “delay and deny” to “delay and distract”. Since the commencement of the global climate talks, from about the 1980s, Shell and BP have said the equivalent of “if the world is serious about acting on global warming (if global warming exists, and global warming is caused by fossil fuels), then the world should agree policy for a framework, and then we will work within that framework.” This is in effect nothing more than the United Nations Framework Convention on Climate Change (UNFCCC) has put forward, so nobody has noticed that Shell and BP are avoiding taking any action themselves here, by making action somebody else’s responsibility.
Shell and BP have known that it would take some considerable time to get unanimity between governments on the reality and severity of climate change. Shell and BP knew that it would take even longer to set up a market in carbon, or a system of carbon dioxide emissions taxation. Shell and BP knew right from the outset that if they kept pushing the ball back to the United Nations, nothing would transpire. The proof of the success of this strategy was the Copenhagen conference in 2009. The next proof of the durability of this delaying tactic will be the outcomes of the Paris 2015 conference. The most that can come out of Paris is another set of slightly improved targets from governments, but no mechanism for translating these into real change.
Shell and BP and the other oil and gas companies have pushed the argument towards a price on carbon, and a market in carbon, and expensive Carbon Capture and Storage technologies. Not that a price on carbon is likely to be anywhere near high enough to pay for Carbon Capture and Storage. But anyway, the point is that these are all distractions. What really needs to happen is that Shell and BP and the rest need to change their products from high carbon to low carbon. They’ve delayed long enough. Now is the time for the United Nations to demand that the fossil fuel companies change their products.
This demand is not just about protecting the survival of the human race, or indeed, the whole biome. Everybody is basically on the same page on this : the Earth should remain liveable-inable. This demand for change is about the survival of Shell and BP as energy companies. They have already started to talk about moving their businesses away from oil to gas. There are high profile companies developing gas-powered cars, trains, ships and possibly even planes. But this will only be a first step. Natural Gas needs to be a bridge to a fully zero carbon world. The oil and gas companies need to transition from oil to gas, and then they need to transition to low carbon gas.
Renewable Gas is not merely “vapourware” – the techniques and technologies for making low carbon gas are available, and have been for decades, or in some cases, centuries. Shell and BP know they can manufacture gas instead of digging it up. They know they can do the chemistry because they already have to do much of the same chemistry in processing fossil hydrocarbons now to meet environmental and performance criteria. BP has known since the 1970s or before that it can recycle carbon in energy systems. Shell is currently producing hydrogen from biomass, and they could do more. A price on carbon is not going to make this transition to low carbon gas. While Shell and BP are delaying the low carbon transition by placing focus on the price of carbon, they could lose a lot of shareholders who shy away from the “carbon bubble” risk of hydrocarbon investment. Shell and BP need to decide for themselves that they want to survive as energy companies, and go public with their plans to transition to low carbon gas, instead of continuing to distract attention away from themselves.
So, some people do not understand why I am opposed to the proposal for a price on carbon put forward by Royal Dutch Shell and their oil and gas company confederates.
Those who have been following developments in climate change policy and the energy sector know that the oil and gas companies have been proposing a price on carbon for decades; and yet little has been achieved in cutting carbon dioxide emissions, even though carbon markets and taxes have been instituted in several regions.
Supporters of pricing carbon dioxide emissions urge the “give it time” approach, believing that continuing down the road of tweaking the price of energy in the global economy will cause a significant change in the types of resources being extracted.
My view is that economic policy and the strengthening of carbon markets and cross-border carbon taxes cannot provide a framework for timely and major shifts in the carbon intensity of energy resources, and here’s a brief analysis of why.
1. A price on carbon shifts the locus of action on to the energy consumer and investor
A price on carbon could be expected to alter the profitability of certain fossil fuel mining, drilling and processing operations. For example, the carbon dioxide emissions of a “tank of gas” from a well-to-wheel or mine-to-wheel perspective, could be made to show up in the price on the fuel station forecourt pump. Leaving aside the question of how the carbon tax or unit price would be applied and redistributed for the moment, a price on carbon dioxide emissions could result in fuel A being more expensive than fuel B at the point of sale. Fuel A could expect to fall in popularity, and its sales could falter, and this could filter its effect back up the chain of production, and have implications on the capital expenditure on the production of Fuel A, and the confidence of the investors in investing in Fuel A, and so the oil and gas company would pull out of Fuel A.
However, the business decisions of the oil and gas company are assumed to be dependent on the consumer and the investor. By bowing to the might god of unit price, Shell and its confederates are essentially arguing that they will act only when the energy consumers and energy investors act. There are problems with this declaration of “we only do what we are told by the market” position. What if the unit price of Fuel A is only marginally affected by the price on carbon ? What if Fuel A is regarded as a superior product because of its premium price or other marketing factors ? This situation actually exists – the sales of petroleum oil-based gasoline and diesel are very healthy, despite the fact that running a car on Natural Gas, biogas or electricity could be far cheaper. Apart from the fact that so many motor cars in the global fleet have liquid fuel-oriented engines, what else is keeping people purchasing oil-based fuels when they are frequently more costly than the alternative options ?
And what about investment ? Fuel A might become more costly to produce with a price on carbon, but it will also be more expensive when it is sold, and this could create an extra margin of profit for the producers of Fuel A, and they could then return higher dividends to their shareholders. Why should investors stop holding stocks in Fuel A when their rates of return are higher ?
If neither consumers nor investors are going to change their practice because Fuel A becomes more costly than Fuel B because of a price on carbon, then the oil and gas company are not going to transition out of Fuel A resources.
For Shell to urge a price on carbon therefore, is a delegation of responsibility for change to other actors. This is irresponsible. Shell needs to lead on emissions reduction, not insist that other people change.
2. A price on carbon will not change overall prices or purchasing decsions
In economic theory, choices about products, goods and services are based on key factors such as trust in the supplier, confidence in the product, availability and sustainability of the service, and, of course, the price. Price is a major determinant in most markets, and artificially altering the price of a vital commodity will certainly alter purchasing decisions – unless, that is, the price of the commodity in question increases across the board. If all the players in the field start offering a more expensive product, for example, because of supply chain issues felt across the market, then consumers will not change their choices.
Now consider the global markets in energy. Upwards of 80% of all energy consumed in the global economy is fossil fuel-based. Putting a price on carbon will raise the prices of energy pretty much universally. There will not be enough cleaner, greener product to purchase, so most purchasing decisions will remain the same. Price differentiation in the energy market will not be established by asserting a price on carbon.
A key part of Shell’s argument is that price differentiation will occur because of a price on carbon, and that this will drive behaviour change, and yet there is nothing to suggest it could do that effectively.
3. A price on carbon will not enable Carbon Capture and Storage
Athough a key part of Shell’s argument about a price on carbon is the rationale that it would stimulate the growth in Carbon Capture and Storage (CCS), it seems unlikely that the world will ever agree to a price on carbon that would be sufficient to stimulate significant levels of CCS. A price on carbon will be deemed to be high enough when it creates a difference in the marginal extra production cost of a unit of one energy resource compared to another. A carbon price can only be argued for on the basis of this optimisation process – after all – a carbon price will be expected to be cost-efficient, and not punitive to markets. In other words, carbon prices will be tolerated if they tickle the final cost of energy, but not if they mangle with it. However, CCS could imply the use of 20% to 45% extra energy consumption at a facility or plant. In other words, CCS would create a parasitic load on energy resources that is not slim enough to be supported by a cost-optimal carbon price.
Some argue that the technology for CCS is improving, and that the parasitic load of CCS at installations could be reduced to around 10% to 15% extra energy consumption. However, it is hard to imagine a price on carbon that would pay even for this. And additionally, CCS will continue to require higher levels of energy consumption which is highly inefficient in the use of resources.
Shell’s argument that CCS is vital, and that a price on carbon can support CCS, is invalidated by this simple analysis.
4. Shell needs to be fully engaged in energy transition
Calling for a price on carbon diverts attention from the fact that Shell itself needs to transition out of fossil fuels in order for the world to decarbonise its energy.
Shell rightly says that they should stick to their “core capabilities” – in other words geology and chemistry, instead of wind power and solar power. However, they need to demonstrate that they are willing to act within their central business activities.
Prior to the explosion in the exploitation of deep geological hydrocarbon resources for liquid and gas fuels, there was an energy economy that used coal and chemistry to manufacture gas and liquid fuels. Manufactured gas could still replace Natural Gas, if there are climate, economic or technological limits to how much Natural Gas can be resourced or safely deployed. Of course, to meet climate policy goals, coal chemistry would need to be replaced by biomass chemistry, and significant development of Renewable Hydrogen technologies.
Within its own production facilities, Shell has the answers to meet this challenge. Instead of telling the rest of the world to change its economy and its behaviour, Shell should take up the baton of transition, and perfect its production of low carbon manufactured gas.
And so it has begun – Shell’s public relations offensive ahead of the 2015 Paris climate talks. The substance of their “advocacy” – and for a heavyweight corporation, it’s less lobbying than badgering – is that the rest of the world should adapt. Policymakers should set a price on carbon, according to Shell. A price on carbon might make some dirty, polluting energy projects unprofitable, and there’s some value in that. A price on carbon might also stimulate a certain amount of Carbon Capture and Storage, or CCS, the capturing and permanent underground sequestration of carbon dioxide at large mines, industrial plant and power stations. But how much CCS could be incentivised by pricing carbon is still unclear. Egging on the rest of the world to price carbon would give Shell the room to carry on digging up carbon and burning it and then capturing it and burying it – because energy prices would inevitably rise to cover this cost. Shell continues with the line that they started in the 1990s – that they should continue to dig up carbon and burn it, or sell it to other people to burn, and that the rest of the world should continue to pay for the carbon to be captured and buried – but Shell has not answered a basic problem. As any physicist could tell you, CCS is incredibly energy-inefficient, which makes it cost-inefficient. A price on carbon wouldn’t solve that. It would be far more energy-efficient, and therefore cost-efficient, to either not dig up the carbon in the first place, or, failing that, recycle carbon dioxide into new energy. Shell have the chemical prowess to recycle carbon dioxide into Renewable Gas, but they are still not planning to do it. They are continuing to offer us the worst of all possible worlds. They are absolutely right to stick to their “core capabilities” – other corporations can ramp up renewable electricity such as wind and solar farms – but Shell does chemistry, so it is appropriate for them to manufacture Renewable Gas. They are already using most of the basic process steps in their production of synthetic crude in Canada, and their processing of coal and biomass in The Netherlands. They need to join the dots and aim for Renewable Gas. This will be far less expensive, and much more efficient, than Carbon Capture and Storage. The world does not need to shoulder the expense and effort of setting a price on carbon. Shell and its fellow fossil fuel companies need to transition out to Renewable Gas.
Hello, hello; what have we here then ? Royal Dutch Shell buying out BG Group (formerly known as British Gas). Is this the start of the great transition out of petroleum oil into gas fuels ?
Volatile crude petroleum oil commodity prices over the last decade have played some undoubted havoc with oil and gas company strategy. High crude prices have pushed the choice of refinery feedstocks towards cheap heavy and immature gunk; influenced decisions about the choices for new petrorefineries and caused ripples of panic amongst trade and transport chiefs : you can’t keep the engine of globalisation ticking over if the key fuel is getting considerably more expensive, and you can’t meet your carbon budgets without restricting supplies.
Low crude commodity prices have surely caused oil and gas corporation leaders to break out into the proverbial sweat. Heavy oil, deep oil, and complicated oil suddenly become unprofitable to mine, drill and pump. Because the economic balance of refinery shifts. Because low commodity prices must translate into low end user refined product prices.
There maybe isn’t an ideal commodity price for crude oil. All the while, as crude oil commodity prices jump around like a medieval flea, the price of Natural Gas, and the gassy “light ends” of slightly unconventional and deep crude oil, stay quite cheap to produce and cheap to use. It’s a shame that there are so many vehicles on the road/sea/rails that use liquid fuels…all this is very likely to change.
Shell appear to be consolidating their future gas business by buying out the competition. Hurrah for common sense ! The next stage of their evolution, after the transition of all oil applications to gas, will be to ramp up Renewable Gas production : low carbon gas supplies will decarbonise every part of the economy, from power generation, to transport, to heating, to industrial chemistry.
This is a viable low carbon solution – to accelerate the use of renewable electricity – wind power and solar principally – and at the same time, transition the oil and gas companies to become gas companies, and thence to Renewable Gas companies.
There are many ways to make a living, but there appear to be zero careers in plainspeaking.
I mean, who could I justify working with, or for ? And would any of them be prepared to accept me speaking my mind ?
Much of what I’ve been saying over the last ten years has been along the lines of “that will never work”, but people generally don’t get consulted or hired for picking holes in an organisation’s pet projects or business models.
Could I imagine myself taking on a role in the British Government ? Short answer : no.
The slightly longer answer : The British Government Department of Energy and Climate Change (DECC) ? No, they’re still hooked on the failed technology of nuclear power, the stupendously expensive and out-of-reach Carbon Capture and Storage (CCS), and the mythical beast of shale gas. OK, so they have a regular “coffee club” about Green Hydrogen (whatever that turns out to be according to their collective ruminations), and they’ve commissioned reports on synthetic methane, but I just couldn’t imagine they’re ever going to work up a serious plan on Renewable Gas. The British Government Department for Transport ? No, they still haven’t adopted a clear vision of the transition of the transport sector to low carbon energy. They’re still chipping away at things instead of coming up with a strategy.
Could I imagine myself taking on a role with a British oil and gas multinational ? Short and very terse and emphatic answer : no.
The extended answer : The oil and gas companies have had generous support and understanding from the world’s governments, and are respected and acclaimed. Yet they are in denial about “unburnable carbon” assets, and have dismissed the need for Energy Change that is the outcome of Peak Oil (whether on the supply or the demand side). Sneakily, they have also played both sides on Climate Change. Several major oil and gas companies have funded or in other ways supported Climate Change science denial. Additionally, the policy recommendations coming from the oil and gas companies are what I call a “delayer’s game”. For example, BP continues to recommend the adoption of a strong price on carbon, yet they know this would be politically unpalatable and take decades (if ever) to bring into effect. Shell continues to argue for extensive public subsidy support for Carbon Capture and Storage (CCS), knowing this would involve such huge sums of money, so it’s never going to happen, at least not for several decades. How on Earth could I work on any project with these corporations unless they adopt, from the centre, a genuine plan for transition out of fossil fuels ? I’m willing to accept that transition necessitates the continued use of Natural Gas and some petroleum for some decades, but BP and Royal Dutch Shell do need to have an actual plan for a transition to Renewable Gas and renewable power, otherwise I would be compromising everything I know by working with them.
Could I imagine myself taking on a role with a large engineering firm, such as Siemens, GE, or Alstom, taking part in a project on manufactured low carbon gas ? I suppose so. I mean, I’ve done an IT project with Siemens before. However, they would need to demonstrate that they are driving for a Renewable Gas transition before I could join a gas project with them. They might not want to be so bold and up-front about it, because they could risk the wrath of the oil and gas companies, whose business model would be destroyed by engineered gas and fuel solutions.
Could I imagine myself building fuel cells, or designing methanation catalysts, or improving hydrogen production, biocoke/biocoal manufacture or carbon dioxide capture from the oceans… with a university project ? Yes, but the research would need to be funded by companies (because all applied academic research is funded by companies) with a clear picture on Energy Change and their own published strategy on transition out of fossil fuels.
Could I imagine myself working on rolling out gas cars, buses and trucks ? Yes. The transition of the transport sector is the most difficult problem in Energy Change. However, apart from projects that are jumping straight to new vehicles running entirely on Hydrogen or Natural Gas, the good options for transition involve converting existing diesel engine vehicles to running mostly on Natural Gas, such as “dual fuel”, still needing roughly 20% of liquid diesel fuel for ignition purposes. So I would need to be involved with a project that aims to supply biodiesel, and have a plan to transition from Natural Gas to Renewable Gas.
Could I imagine myself working with a team that has extensive computing capabilities to model carbon dioxide recycling in power generation plant ? Yes.
Could I imagine myself modelling the use of hydrogen in petroleum refinery, and making technological recommendations for the oil and gas industry to manufacture Renewable Hydrogen ? Possibly. But I would need to be clear that I’m doing it to enable Energy Change, and not to prop up the fossil fuel paradigm – a game that is actually already bust and needs helping towards transition.
Could I imagine myself continuing to research the growth in Renewable Gas – both Renewable Hydrogen and Renewable Methane – in various countries and sectors ? Possibly. It’s my kind of fun, talking to engineers.
But whatever future work I consider myself doing, repeatedly I come up against this problem – whoever asked me to work with them would need to be aware that I do not tolerate non-solutions. I will continue to say what doesn’t work, and what cannot work.
If people want to pay me to tell them that what they’re doing isn’t working, and won’t work, then fine, I’ll take the role.
I’d much rather stay positive, though, and forge a role where I can promote the things that do work, can work and will work.
The project that I’m suitable for doesn’t exist yet, I feel. I’m probably going to continue in one way or another in research, and after that, since I cannot see a role that I could fit easily or ethically, I can see I’m going to have to write my own job description.
In the last couple of years I have researched and written a book about the technologies and systems of Renewable Gas – gas energy fuels that are low in net carbon dioxide emissions. From what I have learned so far, it seems that another energy world is possible, and that the transition is already happening. The forces that are shaping this change are not just climate or environmental policy, or concerns about energy security. Renewable Gas is inevitable because of a range of geological, economic and industrial reasons.
I didn’t train as a chemist or chemical process engineer, and I haven’t had a background in the fossil fuel energy industry, so I’ve had to look at a number of very basic areas of engineering, for example, the distillation and fractionation of crude petroleum oil, petroleum refinery, gas processing, and the thermodynamics of gas chemistry in industrial-scale reactors. Why did I need to look at the fossil fuel industry and the petrochemical industry when I was researching Renewable Gas ? Because that’s where a lot of the change can come from. Renewable Gas is partly about biogas, but it’s also about industrial gas processes, and a lot of them are used in the petrorefinery and chemicals sectors.
In addition, I researched energy system technologies. Whilst assessing the potential for efficiency gains in energy systems through the use of Renewable Electricity and Renewable Gas, I rekindled an interest in fuel cells. For the first time in a long time, I began to want to build something – a solid oxide fuel cell which switches mode to an electrolysis unit that produces hydrogen from water. Whether I ever get to do that is still a question, but it shows how involved I’m feeling that I want to roll up my sleeves and get my hands dirty.
Even though I have covered a lot of ground, I feel I’m only just getting started, as there is a lot more that I need to research and document. At the same time, I feel that I don’t have enough data, and that it will be hard to get the data I need, partly because of proprietary issues, where energy and engineering companies are protective of developments, particularly as regards actual numbers. Merely being a university researcher is probably not going to be sufficient. I would probably need to be an official within a government agency, or an industry institute, in order to be permitted to reach in to more detail about the potential for Renewable Gas. But there are problems with these possible avenues.
You see, having done the research I have conducted so far, I am even more scornful of government energy policy than I was previously, especially because of industrial tampering. In addition, I am even more scathing about the energy industry “playing both sides” on climate change. Even though there are some smart and competent people in them, the governments do not appear to be intelligent enough to see through expensive diversions in technology or unworkable proposals for economic tweaking. These non-solutions are embraced and promoted by the energy industry, and make progress difficult. No, carbon dioxide emissions taxation or pricing, or a market in carbon, are not going to make the kind of changes we need on climate change; and in addition they are going to be extremely difficult and slow to implement. No, Carbon Capture and Storage, or CCS, is never going to become relatively affordable in any economic scenario. No, nuclear power is too cumbersome, slow and dodgy – a technical term – to ever make a genuine impact on the total of carbon emissons. No, it’s not energy users who need to reduce their consumption of energy, it’s the energy companies who need to reduce the levels of fossil fuels they utilise in the energy they sell. No, unconventional fossil fuels, such as shale gas, are not the answer to high emissions from coal. No, biofuels added to petrofuels for vehicles won’t stem total vehicle emissions without reducing fuel consumption and limiting the number of vehicles in use.
I think that the fossil fuel companies know these proposals cannot bring about significant change, which is precisely why they lobby for them. They used to deny climate change outright, because it spelled the end of their industry. Now they promote scepticism about the risks of climate change, whilst at the same time putting their name to things that can’t work to suppress major amounts of emissions. This is a delayer’s game.
Because I find the UK Government energy and climate policy ridiculous on many counts, I doubt they will ever want me to lead with Renewable Gas on one of their projects. And because I think the energy industry needs to accept and admit that they need to undergo a major change, and yet they spend most of their public relations euros telling the world they don’t need to, and that other people need to make change instead, I doubt the energy industry will ever invite me to consult with them on how to make the Energy Transition.
I suppose there is an outside chance that the major engineering firms might work with me, after all, I have been an engineer, and many of these companies are already working in the Renewable Gas field, although they’re normally “third party” players for the most part – providing engineering solutions to energy companies.
Because I’ve had to drag myself through the equivalent of a “petro degree”, learning about the geology and chemistry of oil and gas, I can see more clearly than before that the fossil fuel industry contains within it the seeds of positive change, with its use of technologies appropriate for manufacturing low carbon “surface gas”. I have learned that Renewable Gas would be a logical progression for the oil and gas industry, and also essential to rein in their own carbon emissions from processing cheaper crude oils. If they weren’t so busy telling governments how to tamper with energy markets, pushing the blame for emissions on others, and begging for subsidies for CCS projects, they could instead be planning for a future where they get to stay in business.
The oil and gas companies, especially the vertically integrated tranche, could become producers and retailers of low carbon gas, and take part in a programme for decentralised and efficient energy provision, and maintain their valued contribution to society. At the moment, however, they’re still stuck in the 20th Century.
I’m a positive person, so I’m not going to dwell too much on how stuck-in-the-fossilised-mud the governments and petroindustry are. What I’m aiming to do is start the conversation on how the development of Renewable Gas could displace dirty fossil fuels, and eventually replace the cleaner-but-still-fossil Natural Gas as well.
In an interesting article by two Google engineers, Ross Koningstein and David Fork, "What It Would Really Take to Reverse Climate Change : Today’s renewable energy technologies won’t save us. So what will?", the authors concluded from their modelling scenarios that :-
"While a large emissions cut sure sounded good, this scenario still showed substantial use of natural gas in the electricity sector. That’s because today’s renewable energy sources are limited by suitable geography and their own intermittent power production."
Erm. Yes. Renewable electricity is variable and sometimes not available, because, well, the wind doesn’t always blow and the sun doesn’t always shine, you know. This has been known for quite some time, actually. It’s not exactly news. Natural Gas is an excellent complement to renewable electricity, and that’s why major industrialised country grid networks rely on the pairing of gas and power, and will do so for some time to come. Thus far, no stunner.
What is astonishing is that these brain-the-size-of-a-planet guys do not appear to have asked the awkwardly obvious question of : "so, can we decarbonise the gas supply, then ?" Because the answer is "yes, very largely, yes."
And if you have Renewable Gas backing up Renewable Power, all of a sudden, shazam !, kabam ! and kapoom !, you have An Answer. You can use excess wind power and excess solar power to make gas, and you can store the gas to use when there’s a still, cold period on a wintry night. And at other times of low renewable power, too. And besides using spare green power to make green gas, you can make Renewable Gas in other ways, too.
The Google engineers write :-
"Now, [Research and Development] dollars must go to inventors who are tackling the daunting energy challenge so they can boldly try out their crazy ideas. We can’t yet imagine which of these technologies will ultimately work and usher in a new era of prosperity – but the people of this prosperous future won’t be able to imagine how we lived without them."
Actually, Renewable Gas is completely non-crazy. It’s already being done all over the world in a variety of locations – with a variety of raw resources. We just need to replace the fossil fuel resources with biomass – that’s all.
And there’s more – practically all the technology is over a century old – it just needs refining.
I wonder why the Google boys seem to have been so unaware of this. Maybe they didn’t study the thermodynamics of gas-to-gas reactions at kindergarten, or something.
Thanks to the deliberate misinterpretation of the Google "brothers" article, The Register, James Delingpole’s Breitbart News and Joanne Nova are not exactly helping move the Technological Debate forward, but that’s par for the course. They rubbished climate change science. Now they’ve been shown to be wrong, they’ve moved on, it seems, to rubbishing renewable energy systems. And they’re wrong there, too.
Onwards, my green engineering friends, and upwards.
How do we get things changed in a democracy ? The model of political campaigning that has been established over the last century is failing us. In the past, if there was a problem, a small group of people could create a fuss about it, march some placards to somewhere relevant, write some letters, talk to some dignitaries, chain themselves to some railings, occupy a lobby, get some press, and after some years, maybe, get something done.
These days there are just too many complaints for them all to be heard. Philanthropic, charitable and political messages crowd the stage. In this age of social media, the campaign metaphor has been replaced by a ladder of concern. Concern is expressed. Hopefully others will find that they too are sufficiently concerned, and reflect that concern through some medium. And slowly, it is hoped, this concern climbs the ladder of attention, until it is visible, audible. The entitled and endowed middle classes catch the concern, and repeat it. Lots of emails fly. George Monbiot writes about it in The Guardian. Some speeches are made at serious meetings. Angelina Jolie is invited to grace a conference. And then, hopefully, this concern hits the people who have some kind of leverage over the problem, and they act.
Action is almost guaranteed if the concern is the result of a specific outrage, committed by a specific person or group, and has a specific solution. But otherwise, who knows ? How universal and impactful does a concern need to be before it gets acted upon ? And surely some things don’t need campaigns, because the governments already know enough about problems such as people trafficking, slavery, animal welfare, crime and torture ? After all, things such as prostitution and illegal drug trade are included in national economic statistics.
I took public transport today in London and I was doused in outrage pouring from advertisements asking for charitable giving to prevent the inhuman practice of Female Genital Mutilation (FGM). As I read these appeals, I felt two overwhelming sensations – one of intense anger that children are being permanently injured because of insane and unjustifiable, hateful beliefs about female sexuality. And a second feeling of dragging despair that giving a small donation every month to this organisation would have very little impact on abusive culture, which leads to many forms of violation, not just the unimaginably painful and destructive incision and even resection of a child’s clitoris and the sewing together of her labia, leading to permanent nerve damage, lasting wounds, loss of sexual function, complications from incontinence, ruined relationships, injuries from sexual intercourse, and serious medical risks during childbirth, and possibly the need for reconstructive surgery.
This is a problem which cannot be fixed by expressing normal murmurs of concern, building a wave of concern that climbs a ladder of concern, or making monthly token charitable payments. This concern is not susceptible to a campaign. What this problem needs is regulation, legislation, policing. This concern shouldn’t have to compete with all the other concerns out there, like distressed retired donkeys, threatened butterflies, meltdown polar bears, de-forested orangutans and by-catch dolphins. Some things just shouldn’t happen. They just shouldn’t be tolerated. And they shouldn’t be lost amongst an avalanche of other concerns. This problem is so serious that it should be an automatic priority for all the authorities, co-ordinating to detect and prevent it. This concern shouldn’t have to campaign for funds. Or attention.
Switch to BBC News. Roger Harrabin reports that “The UK’s chief scientist says the oceans face a serious and growing risk from man-made carbon emissions. […] Sir Mark Walport warns that the acidity of the oceans has increased by about 25% since the industrial revolution, mainly thanks to manmade emissions. […] He told BBC News: “If we carry on emitting CO2 [carbon dioxide] at the same rate, ocean acidification will create substantial risks to complex marine food webs and ecosystems.” […] The consequences of acidification are likely to be made worse by the warming of the ocean expected with climate change, a process which is also driven by CO2.”
Media Lens Editors reported this piece. My reaction was – who would be paying attention to this ? This is not the “dangerous climate change comes from global warming” story, this is the “other” carbon problem, the decimation of marine productivity and the whole pyramid of life, resulting from increasing levels of dissolved carbon dioxide in seawater because of higher levels of carbon dioxide in the air. The overwhelmingly major causes of this problem are irrefutably and definitely fossil fuel combustion, and its seriousness is hard to deny, even though Roger Harrabin attempts to make light of it by devoting column inches to a laboratory crab who isn’t getting with the programme.
Ocean acidification is a concern that shouldn’t get lost in amongst other concerns. It should be paid serious levels of attention. And not just by middle class philanthropists who work for non-governmental organisations and charities. And yet, cursory analysis of the segmentation of the population who treat BBC News as a main and trusted information source may suggest that the only readers who would act on this piece are exactly these middle class charity staff, or at a push, retired middle class charity staff.
My Media Lens comment was, “Right expert. Right message. Wrong audience. Wrong medium. The UK Government’s chief scientist. OK. Good. Ocean acidification. OK. Good. No quibbles about whether or not extra carbon dioxide in the atmosphere is a real problem or not (as known as “climate change” or “global warming”, which is real by the way). The BBC News. Wrong medium. Wrong audience. The only people going to listen to this are those who already know about the problem but are still as powerless to act as they were yesterday. The UK Government should present this information to the oil, gas and coal companies with a polite request for them to unveil their plan of action in the face of this undeniable problem.”
There is no reason why this story should be covered in BBC News by Roger Harrabin. What can anybody reading it do about the problem ? There is no purpose for this article. It is a pointless statement of concern, or rather, a belittling rehearsal of the concern. Unless this article, and the thousands like it, lead to the Government demanding answers on Energy Change from the fossil fuel companies, there is no point in reporting it, or in this case, disparaging it with faint humour.
The only time that ocean acidification should appear in a media piece is to report that the problem has been presented to the architects of increased ocean carbon dioxide, and answers have been requested.
And who are the architects of increased atmospheric and ocean carbon dioxide ? Those who mine fossil fuels. Those companies like BP and Shell, ExxonMobil, and all the coal extraction companies should act. They should offer us alternative non-fossil fuel energy. And the news should be about how these companies are taking action to offer us Renewable Hydrogen, Renewable Methane, solar power, wind power and Zero Carbon transport fuels.
Answers from the past will simply not do. Trying to assert that somebody needs to pay for pollution won’t prevent pollution occurring. Carbon taxes or carbon pricing won’t work – since they won’t prevent the mining of fossil fuels – and if fossil fuels are mined, of course they will be burned. Carbon combustion quotas won’t work – since economic wealth is based on burning carbon, so many forces will conspire to maintain levels of fossil fuel combustion. Carbon mining quotas won’t work, since the forces for increasing mining quotas are strong. Carbon trading won’t work, since it won’t reduce the amount of fossil fuels mined – because, obviously, if fossil fuels are mined, they will be burned.
I am tired of reading about climate change, global warming, freshwater stress and ocean acidification in the news. It seems there is nothing I can do that I have not already done that can provide a solution to these problems. Enough with communicating the disaster. I want to read about engineering and energy companies who have switched business models to producing Zero Carbon energy. I want to hear how energy security concern is taking oil, gas and coal companies towards Renewable Everything.
I took some notes from remarks made by Professor David MacKay, the UK Government’s Chief Scientific Advisor, yesterday, 1st May 2014, at an event entitled “How Will We Heat London ?”, held by Max Fordhams as part of the Green Sky Thinking, Open City week. I don’t claim to have recorded his words perfectly, but I hope I’ve captured the gist.
[David MacKay] : [Agreeing with others on the panel – energy] demand reduction is really important. [We have to compensate for the] “rebound effect”, though [where people start spending money on new energy services if they reduce their demand for their current energy services].
SAP is an inaccurate tool and not suitable for the uses we put it too :-
https://www.eden.gov.uk/planning-and-development/building-control/building-control-guidance-notes/sap-calculations-explained/
https://www.dimplex.co.uk/products/renewable_solutions/building_regulations_part_l.htm
Things seem to be under-performing [for example, Combined Heat and Power and District Heating schemes]. It would be great to have data. A need for engineering expertise to get in.
I’m not a Chartered Engineer, but I’m able to talk to engineers. I know a kilowatt from a kilowatt hour [ (Laughter from the room) ]. We’ve [squeezed] a number of engineers into DECC [the Department of Energy and Climate Change].
I’m an advocate of Heat Pumps, but the data [we have received from demonstration projects] didn’t look very good. We hired two engineers and asked them to do the forensic analysis. The heat pumps were fine, but the systems were being wrongly installed or used.
Now we have a Heat Network team in DECC – led by an engineer. We’ve published a Heat Strategy. I got to write the first three pages and included an exergy graph.
[I say to colleagues] please don’t confuse electricity with energy – heat is different. We need not just a green fluffy solution, not just roll out CHP [Combined Heat and Power] [without guidance on design and operation].
Sources of optimism ? Hopefully some of the examples will be available – but they’re not in the shop at the moment.
For example, the SunUp Heat Battery – works by having a series of chambers of Phase Change Materials, about the size of a fridge that you would use to store heat, made by electricity during the day, for use at night, and meet the demand of one home. [Comment from Paul Clegg, Senior Partner at Feilden Clegg Bradley Studios : I first heard about Phase Change Materials back in the 1940s ? 1950s ? And nothing’s come of it yet. ] Why is that a good idea ? Well, if you have a heat pump and a good control system, you can use electricity when it’s cheapest… This is being trialled in 10 homes.
Micro-CHP – [of those already trialled] definitely some are hopeless, with low temperature and low electricity production they are just glorified boilers with a figleaf of power.
Maybe Fuel Cells are going to deliver – power at 50% efficiency [of conversion] – maybe we’ll see a Fuel Cell Micro-Combined Heat and Power unit ?
Maybe there will be hybrid systems – like the combination of a heat pump and a gas boiler – with suitable controls could lop off peaks of demand (both in power and gas).
We have designed the 2050 Pathways Calculator as a tool in DECC. It was to see how to meet the Carbon Budget. You can use it as an energy security calculator if you want. We have helped China, Korea and others to write their own calculators.
A lot of people think CHP is green and fluffy as it is decentralised, but if you’re using Natural Gas, that’s still a Fossil Fuel. If you want to run CHP on biomass, you will need laaaaaarge amounts of land. You can’t make it all add up with CHP. You would need many Wales’-worth of bioenergy or similar ways to make it work.
Maybe we should carry on using boilers and power with low carbon gas – perhaps with electrolysis [A “yay !” from the audience. Well, me, actually]. Hydrogen – the the 2050 Calculator there is no way to put it back into the beginning of the diagram – but it could provide low carbon heat, industry and transport. At the moment we can only put Hydrogen into Transport [in the 2050 Calculator. If we had staff in DECC to do that… It’s Open Source, so if any of you would like to volunteer…
Plan A of DECC was to convert the UK to using lots of electricity [from nuclear power and other low carbon technologies, to move to a low carbon economy], using heat pumps at the consumer end, but there’s a problem in winter [Bill Watts of Max Fordham had already shown a National Grid or Ofgem chart of electricity demand and gas demand over the year, day by day. Electricity demand (in blue) fluctuates a little, but it pretty regular over the year. Gas demand (in red) however, fluctuates a lot, and is perhaps 6 to 10 times larger in winter than in summer.]
If [you abandon Plan A – “electrification of everything”] and do it the other way, you will need a large amount of Hydrogen, and a large Hydrogen store. Electrolysers are expensive, but we are doing/have done a feasibility study with ITM Power – to show the cost of electrolysers versus the cost of your wind turbines [My comment : but you’re going to need your wind turbines to run your electrolysers with their “spare” or “curtailed” kilowatt hours.]
[David Mackay, in questions from the floor] We can glue together [some elements]. Maybe the coming smart controls will help…can help save a load of energy. PassivSystems – control such things as your return temperature [in your Communal or District Heating]…instead of suing your heat provider [a reference to James Gallagher who has problems with his communal heating system at Parkside SE10], maybe you could use smart controls…
[Question] Isn’t using smart controls like putting a Pirelli tyre on a Ford Cortina ? Legacy of poor CHP/DH systems…
[David MacKay in response to the question of insulation] If insulation were enormously expensve, we wouldn’t have to be so enthusastic about it…We need a well-targeted research programme looking at deep retrofitting, instead of letting it all [heat] out.
[Adrian Gault, Committee on Climate Change] We need an effective Government programme to deliver that. Don’t have it in the Green Deal. We did have it [in the previous programmes of CERT and CESP], but since they were cancelled in favour of the Green Deal, it’s gone off a cliff [levels of insulation installations]. We would like to see an initiative on low cost insulation expanded. The Green Deal is not producing a response.
[Bill Watts, Max Fordham] Agree that energy efficiency won’t run on its own. But it’s difficult to do. Not talking about automatons/automation. Need a lot of pressure on this.
[Adrian Gault] Maybe a street-by-street approach…
[Michael Trousdell, Arup] Maybe a rule like you can’t sell a house unless you’ve had the insulation done…
[Peter Clegg] … We can do heat recovery – scavenging the heat from power stations, but we must also de-carbonise the energy supply – this is a key part of the jigsaw.
In the last few weeks I have attended a number of well-intentioned meetings on advances in the field of carbon dioxide emissions mitigation. My overall impression is that there are several failing narratives to be encountered if you make even the shallowest foray into the murky mix of politics and energy engineering.
As somebody rightly pointed out, no capitalist worth their share price is going to spend real money in the current economic environment on new kit, even if they have asset class status – so all advances will necessarily be driven by public subsidies – in fact, significant technological advance has only ever been accomplished by state support.
Disturbingly, free money is also being demanded to roll out decades-old low carbon energy technology – nuclear power, wind power, green gas, solar photovoltaics – so it seems to me the only way we will ever get appropriate levels of renewable energy deployment is by directed, positive public investment.
More to the point, we are now in an era where nobody at all is prepared to spend any serious money without a lucrative slap on the back, and reasons beyond reasons are being deployed to justify this position. For example, the gas-fired power plant operators make claims that the increase in wind power is threatening their profitability, so they are refusing to built new electricity generation capacity without generous handouts. This will be the Capacity Mechanism, and will keep gas power plants from being mothballed. Yes, there is data to support their complaint, but it does still seem like whinging and special pleading.
And the UK Government’s drooling and desperate fixation with new nuclear power has thrown the European Commission into a tizzy about the fizzy promises of “strike price” guaranteed sales returns for the future atomic electricity generation.
But here, I want to contrast two other energy-polity dialogues – one for developing an invaluable energy resource, and the other about throwing money down a hole.
First, let’s take the white elephant. Royal Dutch Shell has for many years been lobbying for state financial support to pump carbon dioxide down holes in the ground. Various oil and gas industry engineers have been selling this idea to governments, federal and sub-federal for decades, and even acted as consultants to the Civil Society process on emissions control – you just need to read the United Nations’ IPCC Climate Change Assessment Report and Special Report output to detect the filigree of a trace of geoengineering fingers scratching their meaning into global intention. Let us take your nasty, noxious carbon dioxide, they whisper suggestively, and push it down a hole, out of sight and out of accounting mind, but don’t forget to slip us a huge cheque for doing so. You know, they add, we could even do it cost-effectively, by producing more oil and gas from emptying wells, resulting from pumping the carbon dioxide into them. Enhanced Oil Recovery – or EOR – would of course mean that some of the carbon dioxide pumped underground would in effect come out again in the form of the flue gas from the combustion of new fossil fuels, but anyway…
And governments love being seen to be doing something, anything, really, about climate change, as long as it’s not too complicated, and involves big players who should be trustworthy. So, you get the Peterhead project picking up a fat cheque for a trial of Carbon Capture and Storage (CCS) in Scotland, and the sidestep hint that if Scotland decides to become independent, this project money could be lost…But this project doesn’t involve much of anything that is really new. The power station that will be used is a liability that ought to be closing now, really, according to some. And the trial will only last for ten years. There will be no EOR – at least – not in the public statements, but this plan could lead the way.
All of this is like pushing a fat kid up a shiny slide. Once Government take their greasy Treasury hands off the project, the whole narrative will fail, falling to an ignominious muddy end. This perhaps explains the underlying desperation of many – CCS is the only major engineering response to emissions that many people can think of – because they cannot imagine burning less fossil fuels. So this wobbling effigy has to be kept on the top of the pedestal. And so I have enjoyed two identical Shell presentations on the theme of the Peterhead project in as many weeks. CCS must be obeyed.
But, all the same, it’s big money. And glaring yellow and red photo opps. You can’t miss it. And then, at the other end of the scale of subsidies, is biogas. With currently low production volumes, and complexities attached to its utilisation, anaerobically digesting wastes of all kinds and capturing the gas for use as a fuel, is a kind of token technology to many, only justified because methane is a much stronger greenhouse gas than carbon dioxide, so it needs to be burned.
The subsidy arrangements for many renewable energy technologies are in flux. Subsidies for green gas will be reconsidered and reformulated in April, and will probably experience a degression – a hand taken off the tiller of driving energy change.
At an evening biogas briefing given by Rushlight this week, I could almost smell a whiff of despair and disappointment in the levels of official support for green gas. It was freely admitted that not all the planned projects around the country will see completion, not only because of the prevailing economic climate, but because of the vagaries of feedstock availability, and the complexity of gas cleaning regulations.
There was light in the tunnel, though, even if the end had not been reached – a new Quality Protocol for upgrading biogas to biomethane, for injection into the gas grid, has been established. You won’t find it on the official UK Goverment website, apparently, as it has fallen through the cracks of the rebranding to gov.uk, but here it is, and it’s from the Environment Agency, so it’s official :-

https://adbiogas.co.uk/2014/01/30/biomethane-quality-protocol-published/
Here’s some background :-
https://www.environment-agency.gov.uk/aboutus/wfo/epow/124111.aspx
To get some picture of the mess that British green energy policy is in, all you need do is take a glance at Germany and Denmark, where green gas is considered the “third leg of the stool”, stabilising renewable energy supply with easily-stored low carbon gas, to balance out the peaks and troughs in wind power and solar power provision.
Green gas should not be considered a nice-to-have minor addition to the solutions portfolio in my view. The potential to de-carbonise the energy gas supply is huge, and the UK are missing a trick here – the big money is being ladled onto the “incumbents” – the big energy companies who want to carry on burning fossil fuels but sweep their emissions under the North Sea salt cavern carpet with CCS, whilst the beer change is being reluctantly handed out as a guilt offering to people seeking genuinely low carbon energy production.
Seriously – where the exoplanet are we at ?
Here is further email exchange with Professor Richard Sears, following on from a previous web log post.
From: Richard A. Sears
Date: 24 February 2014
To: Jo Abbess
Subject: Question from your TED talk
Jo,
I was looking back over older emails and saw that I had never responded to your note. It arrived as I was headed to MIT to teach for a week and then it got lost. Sorry about that.
Some interesting questions. I don’t know anybody working specifically on wind power to gas options. At one time Shell had a project in Iceland using geothermal to make hydrogen. Don’t know what its status is but if you search on hydrogen and Iceland on the Shell website I’m sure there’s something. If the Germans have power to gas as a real policy option I’d poke around the web for information on who their research partners are for this.
Here are a couple of high level thoughts. Not to discourage you because real progress comes from asking new questions, but there are some physical fundamentals that are important.
Direct air capture of anything using current technology is prohibitively expensive to do at scale for energy. More energy will be expended in capture and synthesis than the fuels would yield.
Gaseous fuels are problematic on their own. Gas doesn’t travel well and is difficult to contain at high energy densities as that means compressing or liquefying it. That doesn’t make anything impossible, but it raises many questions about infrastructure and energy balance. If we take the energy content of a barrel of oil as 1.0, then a barrel of liquefied natural gas is about 0.6, compressed natural gas which is typically at about 3600psi is around 0.3, and a barrel (as a measure of volume equal to 42 US gallons) of natural gas at room temperature and pressure is about 0.0015 (+/-). Also there’s a real challenge in storing and transporting gasses as fuel at scale, particularly motor fuel to replace gasoline and diesel.
While there is some spare wind power potential that doesn’t get utilized because of how the grid must be managed, I expect it is a modest amount of energy compared to what we use today in liquid fuels. I think what that means is that while possible, it’s more likely to happen in niche local markets and applications rather than at national or global scales.
If you haven’t seen it, a nice reference on the potential of various forms of sustainable energy is available free and online here. https://www.withouthotair.com/

Dear Richard,
Many thanks for getting back to me. Responses are nice – even if they
are months late. As they say – better late than never, although with
climate change, late action will definitely be unwise, according to an
increasing number of people.
I have indeed seen the website, and bought and spilled coffee on the
book of Professor David MacKay’s “Sustainable Energy Without The Hot
Air” project. It is legendary. However, I have checked and he has only
covered alternative gas in a couple of paragraphs – in notes. By
contrast, he spent a long chapter discussing how to filter uranium out
of seawater and other nuclear pursuits.
Yet as a colleague of mine, who knows David better than I do, said to
me this morning, his fascination with nuclear power is rather naive,
and his belief in the success of Generation III and Generation IV
lacks evidence. Plus, if we get several large carbon dioxide
sequestration projects working in the UK – Carbon Capture and Storage
(CCS) – such as the Drax pipeline (which other companies will also
join) and the Shell Peterhead demonstration, announced today, then we
won’t need new nuclear power to meet our 4th Carbon Budget – and maybe
not even the 5th, either (to be negotiated in 2016, I hear) :-
We don’t need to bury this carbon, however; we just need to recycle
it. And the number of ways to make Renewable Hydrogen, and
energy-efficiently methanate carbon monoxide and carbon dioxide with
hydrogen, is increasing. People are already making calculations on how
much “curtailed” or spare wind power is likely to be available for
making gas in 10 years’ time, and if solar power in the UK is
cranked/ramped up, then there will be lots of juicy cost-free power
ours for the taking – especially during summer nights.
Direct Air Capture of carbon dioxide is a nonsensical proposition.
Besides being wrong in terms of the arrow of entropy, it also has the
knock-on effect of causing carbon dioxide to come back out of the
ocean to re-equilibrate. I recently read a paper by climate scientists
that estimated that whatever carbon dioxide you take out of the air,
you will need to do almost all of it again.
Instead of uranium, we should be harvesting carbon dioxide from the
oceans, and using it to make gaseous and liquid fuels.
Gaseous fuels and electricity complement each other very well –
particularly in storage and grid balancing terms – there are many
provisions for the twins of gas and power in standards, laws, policies
and elsewhere. Regardless of the limitations of gas, there is a huge
infrastructure already in place that can store, pipe and use it, plus
it is multi-functional – you can make power, heat, other fuels and
chemicals from gas. In addition, you can make gas from a range of
resources and feedstocks and processing streams – the key quartet of
chemical gas species keep turning up : hydrogen, methane, carbon
monoxide and carbon dioxide – whether you are looking at the exhaust
from combustion, Natural Gas, industrial furnace producer gas,
biological decomposition, just about everywhere – the same four gases.
Energy transition must include large amounts of renewable electricity
– because wind and solar power are quick to build yet long nuclear
power lead times might get extended in poor economic conditions. The
sun does not always shine and the wind does not always blow (and the
tide is not always in high flux). Since demand profiles will never be
able to match supply profiles exactly, there will always be spare
power capacity that grids cannot use. So Power to Gas becomes the
optimal solution. At least until there are ways to produce Renewable
Hydrogen at plants that use process heat from other parts of the
Renewable Gas toolkit. So the aims are to recycle carbon dioxide from
gas combustion to make more gas, and recycle gas production process
heat to make hydrogen to use in the gas production process, and make
the whole lot as thermally balanced as possible. Yes. We can do that.
Lower the inputs of fresh carbon of any form, and lower the energy
requirements to make manufactured gas.
I met somebody working with Jacobs who was involved in the Carbon
Recycling project in Iceland. Intriguing, but an order of magnitude
smaller than I think is possible.
ITM Power in the UK are doing a Hydrogen-to-gas-grid and methanation
project in Germany with one of the regions. They have done several
projects with Kiwa and Shell on gas options in Europe. I know of the
existence of feasibility reports on the production of synthetic
methane, but I have not had the opportunity to read them yet…
I feel quite encouraged that Renewable Gas is already happening. It’s
a bit patchy, but it’s inevitable, because the narrative of
unconventional fossil fuels has many flaws. I have been looking at
issues with reserves growth and unconventionals are not really
commensurate with conventional resources. There may be a lot of shale
gas in the ground, but getting it out could be a long process, so
production volumes might never be very good. In the USA you’ve had
lots of shale gas – but that’s only been supported by massive drilling
programmes – is this sustainable ?
BP have just finished building lots of dollars of kit at Whiting to
process sour Natural Gas. If they had installed Renewable Gas kit
instead of the usual acid gas and sulfur processing, they could have
been preparing for the future. As I understand it, it is possible to
methanate carbon dioxide without first removing it from the rest of
the gas it comes in – so methanating sour gas to uprate it is a viable
option as far as I can see. The hydrogen sulfide would still need to
be washed out, but the carbon dioxide needn’t be wasted – it can be
made part of the fuel. And when the sour gas eventually thins out,
those now methanating sour gas can instead start manufacturing gas
from low carbon emissions feedstocks and recycled carbon.
I’m thinking very big.
Regards,
jo.
A normal, everyday Monday morning at Energy Geek Central. Yes, this is a normal conversation for me to take part in on a Monday morning. Energy geekery at breakfast. Perfect.
Nuclear Flower Power
This whole UK Government nuclear power programme plan is ridiculous ! 75 gigawatts (GW) of Generation III nuclear fission reactors ? What are they thinking ? Britain would need to rapidly ramp up its construction capabilities, and that’s not going to happen, even with the help of the Chinese. (And the Americans are not going to take too kindly to the idea of China getting strongly involved with British energy). And then, we’d need to secure almost a quarter of the world’s remaining reserves of uranium, which hasn’t actually been dug up yet. And to cap it all, we’d need to have 10 more geological disposal repositories for the resulting radioactive spent fuel, and we haven’t even managed to negotiate one yet. That is, unless we can burn a good part of that spent fuel in Generation IV nuclear fission reactors – which haven’t even been properly demonstrated yet ! Talk about unconscionable risk !
Baseload Should Be History By Now, But…
Whatever the technological capability for nuclear power plants to “load follow” and reduce their output in response to a chance in electricity demand, Generation III reactors would not be run as anything except “baseload” – constantly on, and constantly producing a constant amount of power – although they might turn them off in summer for maintenance. You see, the cost of a Generation III reactor and generation kit is in the initial build – so their investors are not going to permit them to run them at low load factors – even if they could.
There are risks to running a nuclear power plant at partial load – mostly to do with potential damage to the actual electricity generation equipment. But what are the technology risks that Hinkley Point C gets built, and all that capital is committed, and then it only runs for a couple of years until all that high burn up fuel crumbles and the reactors start leaking plutonium and they have to shut it down permanently ? Who can guarantee it’s a sound bet ?
If they actually work, running Generation III reactors at constant output as “baseload” will also completely mess with the power market. In all of the scenarios, high nuclear, high non-nuclear, or high fossil fuels with Carbon Capture and Storage (CCS), there will always need to be some renewables in the mix. In all probability this will be rapidly deployed, highly technologically advanced solar power photovoltaics (PV). The amount of solar power that will be generated will be high in summer, but since you have a significant change in energy demand between summer and winter, you’re going to have a massive excess of electricity generation in summer if you add nuclear baseload to solar. Relative to the demand for energy, you’re going to get more Renewable Energy excess in summer and under-supply in winter (even though you get more offshore wind in winter), so it’s critical how you mix those two into your scenario.
The UK Government’s maximum 75 GW nuclear scenario comprises 55 GW Generation III and 20 GW Generation IV. They could have said 40 GW Gen III to feed Gen IV – the spent fuel from Gen III is needed to kick off Gen IV. Although, if LFTR took off, if they had enough fluoride materials there could be a Thorium way into Gen IV… but this is all so technical, no MP [ Member of Parliament ] is going to get their head round this before 2050.
The UK Government are saying that 16 GW of nuclear by 2030 should be seen as a first tranche, and that it could double or triple by 2040 – that’s one heck of a deployment rate ! If they think they can get 16 GW by 2030 – then triple that by 10 years later ? It’s not going to happen. And even 30 GW would be horrific. But it’s probably more plausible – if they can get 16 GW by 2030, they can arguably get double that by 2040.
As a rule of thumb, you would need around 10 tonnes of fissionable fuel to kickstart a Gen IV reactor. They’ve got 106 tonnes of Plutonium, plus 3 or 4 tonnes they recently acquired – from France or Germany (I forget which). So they could start 11 GW of Gen IV – possibly the PRISM – the Hitachi thing – sodium-cooled. They’ve been trying them since the Year Dot – these Fast Reactors – the Breeders – Dounreay. People are expressing more confidence in them now – “Pandora’s Promise” hangs around the narrative that the Clinton administration stopped research into Fast Reactors – Oak Ridge couldn’t be commercial. Throwing sodium around a core 80 times hotter than current core heats – you can’t throw water at it easily. You need something that can carry more heat out. It’s a high technological risk. But then get some French notable nuclear person saying Gen IV technologies – “they’re on the way and they can be done”.
Radioactive Waste Disposal Woes
The point being is – if you’re commissioning 30 GW of Gen III in the belief that Gen IV will be developed – then you are setting yourself up to be a hostage to technological fortune. That is a real ethical consideration. Because if you can’t burn the waste fuel from Gen III, you’re left with up to 10 radioactive waste repositories required when you can’t even get one at the moment. The default position is that radioactive spent nuclear fuel will be left at the power stations where they’re created. Typically, nuclear power plants are built on the coast as they need a lot of cooling water. If you are going for 30 GW you will need a load of new sites – possibly somewhere round the South East of England. This is where climate change comes in – rising sea levels, increased storm surge, dissolving, sinking, washed-away beaches, more extreme storms […] The default spent fuel scenario with numerous coastal decommissioned sites with radioactive interim stores which contain nearly half the current legacy radioactive waste […]
Based on the figures from the new Greenpeace report, I calculate that the added radioactive waste and radioactive spent fuel arisings from a programme of 16 GW of nuclear new build would be 244 million Terabequerel (TBq), compared to the legacy level of 87 million TBq.
The Nuclear Decommissioning Authority (NDA) are due to publish their Radioactive Waste Inventory and their Report on Radioactive Materials not in the Waste Inventory at the end of January 2014. We need to keep a watch out for that, because they may have adapted their anticipated Minimum and Maxmium Derived Inventory.
Politics Is Living In The Past
What you hear from politicians is they’re still talking about “baseload”, as if they’ve just found the Holy Grail of Energy Policy. And failed nuclear power. Then tidal. And barrages. This is all in the past. Stuff they’ve either read – in an article in a magazine at the dentist’s surgery waiting room, and they think, alright I’ll use that in a TV programme I’ve been invited to speak on, like Question Time. I think that perhaps, to change the direction of the argument, we might need to rubbish their contribution. A technological society needs to be talking about gasification, catalysis. If you regard yourselves as educated, and have a technological society – your way of living in the future is not only in manufacturing but also ideas – you need to be talking about this not that : low carbon gas fuels, not nuclear power. Ministers and senior civil servants probably suffer from poor briefing – or no briefing. They are relying on what is literally hearsay – informal discussions, or journalists effectively representing industrial interests. Newspapers are full of rubbish and it circulates, like gyres in the oceans. Just circulates around and around – full of rubbish.
I think part of the problem is that the politicians and chief civil servants and ministers are briefed by the “Old Guard” – very often the ex-nuclear power industry guard. They still believe in big construction projects, with long lead times and massive capital investment, whereas Renewable Electricity is racing ahead, piecemeal, and private investors are desperate to get their money into wind power and solar power because the returns are almost immediate and risk-free.
Together in Electric Dreams
Question : Why are the UK Government ploughing on with plans for so much nuclear power ?
1. They believe that a lot of transport and heat can be made to go electric.
2. They think they can use spent nuclear fuel in new reactors.
3. They think it will be cheaper than everything else.
4. They say it’s vital for UK Energy Security – for emissions reductions, for cost, and for baseload. The big three – always the stated aim of energy policy, and they think nuclear ticks all those three boxes. But it doesn’t.
What they’ll say is, yes, you have to import uranium, but you’ve got a 4 year stock. Any war you’re going to get yourselves involved in you can probably resolve in 4 days, or 4 weeks. If you go for a very high nuclear scenario, you would be taking quite a big share of the global resource of uranium. There’s 2,600 TWh of nuclear being produced globally. And global final energy demand is around 100,000 TWh – so nuclear power currently produces around 2.6% of global energy supply. At current rates of nuclear generation, according to the World Nuclear Association, you’ve got around 80 years of proven reserves and probably a bit more. Let’s say you double nuclear output by 2050 or 2040 – but in the same time you might just have enough uranium – and then find a bit more. But global energy demand rises significantly as well – so nuclear will still only provide around 3% of global energy demand. That’s not a climate solution – it’s just an energy distraction. All this guff about fusion. Well.
Cornering The Market In Undug Uranium
A 75 GW programme would produce at baseload 590 TWh a year – divide by 2,600 – is about 23% of proven global uranium reserves. You’re having to import, regardless of what other countries are doing, you’re trying to corner the market – roughly a quarter. Not even a quarter of the market – a quarter of all known reserves – it’s not all been produced yet. It’s still in the ground. So could you be sure that you could actually run these power stations if you build them ? Without global domination of the New British Empire […]. The security issues alone – defending coastal targets from a tweeb with a desire to blow them up. 50 years down the line they’re full of radioactive spent fuel that won’t have a repository to go to – we don’t want one here – and how much is it going to cost ?
My view is that offshore wind will be a major contributor in a high or 100% Renewable Electricity scenario by 2050 or 2060. Maybe 180 GW, that will also be around 600 TWh a year – comparable to that maximum nuclear programme. DECC’s final energy demand 2050 – several scenarios – final energy demand from 6 scenarios came out as between roughly 1,500 TWh a year and the maximum 2,500 TWh. Broadly speaking, if you’re trying to do that just with Renewable Electricity, you begin to struggle quite honestly, unless you’re doing over 600 TWh of offshore wind, and even then you need a fair amount of heat pump stuff which I’m not sure will come through. The good news is that solar might – because of the cost and technology breakthroughs. That brings with it a problem – because you’re delivering a lot of that energy in summer. The other point – David MacKay would say – in his book his estimate was 150 TWh from solar by 2050, on the grounds that that’s where you south-facing roofs are – you need to use higher efficiency triple junction cells with more than 40% efficiency and this would be too expensive for a rollout which would double or triple that 150 TWh – that would be too costly – because those cells are too costly. But with this new stuff, you might get that. Not only the cost goes down, but the coverage goes down. Not doing solar across swathes of countryside. There have always been two issues with solar power – cost and where it’s being deployed.
Uh-Oh, Summer Days. Uh-Oh, Summer Nights
With the solar-wind headline, summer days and summer nights are an issue.
With the nuclear headline, 2040 – they would have up to 50 GW, and that would need to run at somewhere between 75% and 95% capacity – to protect the investment and electric generation turbines.
It will be interesting to provide some figures – this is how much over-capacity you’re likely to get with this amount of offshore wind. But if you have this amount of nuclear power, you’ll get this amount […]
Energy demand is strongly variable with season. We have to consider not just power, but heat – you need to get that energy out in winter – up to 4 times as much during peak in winter evenings. How are you going to do that ? You need gas – or you need extensive Combined Heat and Power (CHP) (which needs gas). Or you need an unimaginable deployment of domestic heat pumps. Air source heat pumps won’t work at the time you need them most. Ground source heat pumps would require the digging up of Britain – and you can’t do that in most urban settings.
District Heat Fields
The other way to get heat out to everyone in a low carbon world – apart from low carbon gas – is having a field-based ground source heat pump scheme – just dig up a field next to a city – and just put in pipes and boreholes in a field. You’re not disturbing anybody. You could even grow crops on it next season. Low cost and large scale – but would need a District Heating (DH) network. There are one or two heat pump schemes around the world. Not sure if they are used for cooling in summer or heat extraction in the winter. The other thing is hot water underground. Put in an extra pipe in the normal channels to domestic dwellings. Any excess heat from power generation or electrolysis or whatever is put down this loop and heats the sub-ground. Because heat travels about 1 metre a month in soil, that heat should be retained for winter. A ground source heat sink. Geothermal energy could come through – they’re doing a scheme in Manchester. If there’s a nearby heat district network – it makes it easier. Just want to tee it into the nearest DH system. The urban heat demand is 150 TWh a year. You might be able to put DH out to suburban areas as well. There are 9 million gas-connected suburban homes – another about 150 TWh there as well – or a bit more maybe. Might get to dispose of 300 TWh in heat through DH. The Green Deal insulation gains might not be what is claimed – and condensing gas boiler efficiencies are not that great – which feeds into the argument that in terms of energy efficiency, you not only want to do insulation, but also DH – or low carbon gas. Which is the most cost-effective ? Could argue reasonable energy efficiency measures are cheapest – but DH might be a better bet. That involves a lot of digging.
Gas Is The Logical Answer
But everything’s already laid for gas. (…but from the greatest efficiency first perspective, if you’re not doing DH, you’re not using a lot of Renewable Heat you could otherwise use […] )
The best package would be the use of low carbon gases and sufficient DH to use Renewable Heat where it is available – such as desalination, electrolysis or other energy plant. It depends where the electrolysis is being done.
The Age of Your Carbon
It also depends on which carbon atoms you’re using. If you are recycling carbon from the combustion of fossil fuels into Renewable Gas, that’s OK. But you can’t easily recapture carbon emissions from the built environment (although you could effectively do that with heat storage). You can’t do carbon capture from transport either. So your low carbon gas has to come from biogenic molecules. Your Renewable Gas has to be synthesised using biogenic carbon molecules rather than fossil ones.
[…] I’m using the phrase “Young Carbon”. Young Carbon doesn’t have to be from plants – biological things that grow.
Well, there’s Direct Air Capture (DAC). It’s simple. David Sevier, London-based, is working on this. He’s using heat to capture carbon dioxide. You could do it from exhaust in a chimney or a gasification process – or force a load of air through a space. He would use heat and cooling to create an updraft. It would enable the “beyond capture” problem to be circumvented. Cost is non-competitive. Can be done technically. Using reject heat from power stations for the energy to do it. People don’t realise you can use a lot of heat to capture carbon, not electricity.
Young Carbon from Seawater
If you’re playing around with large amounts of seawater anyway – that is, for desalination for irrigation, why not also do Renewable Hydrogen, and pluck the Carbon Dioxide out of there too to react with the Renewable Hydrogen to make Renewable Methane ? I’m talking about very large amounts of seawater. Not “Seawater Greenhouses” – condensation designs mainly for growing exotic food. If you want large amounts of desalinated water – and you’re using Concentrated Solar Power – for irrigating deserts – you would want to grow things like cacti for biological carbon.
Say you had 40 GW of wind power on Dogger Bank, spinning at 40% load factor a year. You’ve also got electrolysers there. Any time you’re not powering the grid, you’re making gas – so capturing carbon dioxide from seawater, splitting water for hydrogen, making methane gas. Wouldn’t you want to use flash desalination first to get cleaner water for electrolysis ? Straight seawater electrolysis is also being done.
It depends on the relative quantities of gas concentrated in the seawater. If you’ve got oxygen, hydrogen and carbon dioxide, that would be nice. You might get loads of oxygen and hydrogen, and only poor quantities of carbon dioxide ?
But if you could get hydrogen production going from spare wind power. And even if you had to pipe the carbon dioxide from conventional thermal power plants, you’re starting to look at a sea-based solution for gas production. Using seawater, though, chlorine is the problem […]
Look at the relative density of molecules – that sort of calculation that will show if this is going to fly. Carbon dioxide is a very fixed, stable molecule – it’s at about the bottom of the energy potential well – you have to get that reaction energy from somewhere.
How Much Spare Power Will There Be ?
If you’ve got an offshore wind and solar system. At night, obviously, the solar’s not working (unless new cells are built that can run on infrared night-time Earthshine). But you could still have 100 GWh of wind power at night not used for the power grid. The anticipated new nuclear 40 GW nuclear by 2030 will produce about 140 GWh – this would just complicate problems – adding baseload nuclear to a renewables-inclusive scenario. 40 GW is arguably a reasonable deployment of wind power by 2030 – low if anything.
You get less wind in a nuclear-inclusive scenario, but the upshot is you’ve definitely got a lot of power to deal with on a summer night with nuclear power. You do have with Renewable Electricity as well, but it varies more. Whichever route we take we’re likely to end up with excess electricity generation on summer nights.
In a 70 GW wind power deployment (50 GW offshore, 20 GW onshore – 160 TWh a year), you might have something like 50 to 100 GWh per night of excess (might get up to 150 GWh to store on a windy night). But if you have a 16 GW nuclear deployment by 2030 (125 TWh a year), you are definitely going to have 140 GWh of excess per night (that’s 16 GW for 10 hours less a bit). Night time by the way is roughly between 9pm and 7am between peak demands.
We could be making a lot of Renewable Gas !
Can you build enough Renewable Gas or whatever to soak up this excess nuclear or wind power ?
The energy mix is likely to be in reality somewhere in between these two extremes of high nuclear or high wind.
But if you develop a lot of solar – so that it knocks out nuclear power – it will be the summer day excess that’s most significant. And that’s what Germany is experiencing now.
Choices, choices, choices
There is a big choice in fossil fuels which isn’t really talked about very often – whether the oil and gas industry should go for unconventional fossil fuels, or attempt to make use of the remaining conventional resources that have a lower quality. The unconventionals narrative – shale gas, coalbed methane, methane hydrates, deepwater gas, Arctic oil and gas, heavy oil, is running out of steam as it becomes clear that some of these choices are expensive, and environmentally damaging (besides their climate change impact). So the option will be making use of gas with high acid gas composition. And the technological solutions for this will be the same as needed to start major production of Renewable Gas.
Capacity Payments
But you still need to answer the balancing question. If you have a high nuclear power scenario, you need maybe 50 TWh a year of gas-fired power generation. If high Renewable Electricity, you will need something like 100 TWh of gas, so you need Carbon Capture and Storage – or low carbon gas.
Even then, the gas power plants could be running only 30% of the year, and so you will need capacity payments to make sure new flexible plants get built and stay available for use.
If you have a high nuclear scenario, coupled with gas, you can meet the carbon budget – but it will squeeze out Renewable Electricity. If high in renewables, you need Carbon Capture and Storage (CCS) or Carbon Capture and Recycling into Renewable Gas, but this would rule out nuclear power. It depends which sector joins up with which.
Carbon Capture, Carbon Budget
Can the Drax power plant – with maybe one pipeline 24 inches in diameter, carrying away 20 megatonnes of carbon dioxide per year – can it meet the UK’s Carbon Budget target ?
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.
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 :-
https://uk.groups.yahoo.com/group/Claverton/message/12361
“Indicative costs of decarbonizing European city heating with electrical distribution compared to district heating pipe distribution of large scale wind energy and with particular attention to transition to the above methods and energy storage costs to address intermittency and variability of wind power.”
This would have been an assessment of the relative costs of decarbonising European city heating with either :-
Strategy 1)
“Gas-fired Combined Cycle Gas Turbine (CCGT) generation plant plus domestic (residential sector) electric heat pumps as the transition solution; and in the long term, large scale wind energy replacing the CCGT – which is retained as back up for low wind situations; and with pumped hydro electrical storage to deal with intermittency /variability of wind energy and to reduce back up fuel usage.”
or
Strategy 2)
“CCGT Combined Heat and Power (CHP) plus district heat (DH) as the transition solution; and in the long term, large scale wind energy replacing the CCGT CHP heat but with the CCGT retained as back up for low wind situations and with hot water energy storage to deal with intermittency / variability and to reduce back up fuel usage.”
With “the impact of [a programme of building retrofits for] insulation on each strategy is also assessed.”
Dave’s European research background is of relevance here, as co-author of a 215-pager SETIS programme paper complete with pretty diagrams :-
https://setis.ec.europa.eu/system/files/1.DHCpotentials.pdf
Although Dave Andrews was also at the PRASEG drinks reception, he didn’t get the opportunity to address the conference. Which was a shame as his shirt was electric.

“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].

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

Previously, my understanding was that the development of microbiological life included a good number of methanogens (micro-life that produces methane as a waste product) and methanotrophs (those that “trough” on methane), but that hydrogenogen (“respiring” hydrogen gas) and hydrogenotroph (metabolising hydrogen) species were a minority, and that this was reflected in modern-day decomposition, such as the cultures used in biogas plants for anaerobic digestion. If there were high densities of hydrogen cycle lifeforms in the early Earth, maybe there are remnants, descendants of this branch of the tree of life, optimal at producing hydrogen gas as a by-product, which could be employed for biohydrogen production, but which haven’t yet been scoped. After all, it has only been very recently that psychrophiles have been added to the range of microorganisms that have been found useful in biogas production – cold-loving, permafrost-living bugs to complement the thermophile and mesophile species. Since hydrogen and methane are both ideal gas fuels, for a variety of reasons, including gas storage, combustion profiles and simple chemistry, I decided I needed to learn a little more. I have now read a plethora of new theories and several books about the formation of the Earth (and the Moon) in the Hadean Eon, the development of Earth’s atmosphere, the development of life in the Archaean Eon, and the evolution of life caused by climate change, and these developments in living beings causing climate change in their turn. Most of this knowledge is mediated to us by geology, and geobiology. But right at its heart is catalytic chemistry, once again. Here’s Robert Hazen (Robert M. Hazen) from page 138 of “The Story of Earth” :- “Amino acids, sugars, and the components of DNA and RNA adsorb onto all of Earth’s most common rock-forming minerals […] We concluded that wherever the prebiotic ocean contacted minerals, highly concentrated arrangements of life’s molecules are likely to have emerged from the formless broth […] Many other researchers have also settled on such a conclusion – indeed, more than a few prominent biologists have also gravitated to minerals, because origins-of-life scenarios that involve only oceans and atmosphere face insurmountable problems in accounting for efficient mechanisms of molecular selection and concentration. Solid minerals have an unmatched potential to select, concentrate, and organize molecules. So minerals much have played a central role in life’s origins. Biochemistry is complex, with interwoven cycles and networks of molecular reactions. For those intricately layered processes to work, molecules have to have just the right sizes and shapes. Molecular selection is the task of finding the best molecule for each biochemical job, and template-directed selection on mineral surfaces is now the leading candidate for how nature did it […] left- and right-handed molecules […] It turns out that life is incredibly picky : cells almost exclusively employ left-handed amino acids and right-handed sugars. Chirality matters […] Our recent experiments have explored the possibility that chiral mineral surfaces played the starring role in selecting handed molecules, and perhaps the origins of life as well. […] Our experiments showed that certain left-handed molecules can aggregate on one set of crystal surfaces, while the mirror image […] on other sets […] As handed molecules are separated and concentrated, each surface becomes a tiny experiment in molecular selection and organization. On its own, no such natural experiment with minerals and molecules is likely to have generated life. But take countless trillions of trillions of trillions of mineral surfaces, each bathed in molecule-rich organic broth […] The tiny fraction of all those molecular combinations that wound up displaying easier self-assembly, or developed a stronger binding to mineral surfaces […] survived […] possibly to learn new tricks.” | |

 [ Image Credit : anonymous ] | Yet again, the fossil fuel companies think they can get away with uncommented public relations in my London neighbourhood. Previously, it was BP, touting its green credentials in selling biofuels, at the train station, ahead of the Olympic Games. For some reason, after I made some scathing remarks about it, the advertisement disappeared, and there was a white blank board there for weeks. |
This time, it’s Esso, and they probably think they have more spine, as they’ve taken multiple billboard spots. In fact, the place is saturated with this advertisement. And my answer is – yes, fuel economy is important to me – that’s why I don’t have a car. And if this district is anything to go by, Esso must be pouring money into this advertising campaign, and so my question is : why ? Why aren’t they pouring this money into biofuels research ? Answer : because that’s not working. So, why aren’t they putting this public relations money into renewable gas fuels instead, sustainable above-surface gas fuels that can be used in compressed gas cars or fuel cell vehicles ? Are Esso retreating into their “core business” like BP, and Shell, concentrating on petroleum oil and Natural Gas, and thereby exposing all their shareholders to the risk of an implosion of the Carbon Bubble ? Or another Deepwater Horizon, Macondo-style blowout ? Meanwhile, the movement for portfolio investors to divest from fossil fuel assets continues apace… | |
