  • Fields of Diesel Generators

    Posted on February 19th, 2016 Jo No comments

    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.

  • A Partial Meeting of Engineering Minds

    Posted on July 14th, 2015 Jo No comments

    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.

  • Nuclear Power Is Not An Energy Policy

    Posted on June 23rd, 2015 Jo No comments

    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.

  • Zero Careers In Plainspeaking

    Posted on March 5th, 2015 Jo 1 comment

    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.

  • Renewable Energy : Google Blind

    Posted on November 23rd, 2014 Jo 2 comments

    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.

  • All Kinds of Gas

    Posted on May 2nd, 2014 Jo No comments

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

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

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

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

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

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

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

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

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

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

    Sigh. I think I’m going to need to start sending out Freedom of Information requests… Several cups of tea later…


    To: Information Rights Unit, Department for Business, Innovation & Skills, 5th Floor, Victoria 3, 1 Victoria Street, London SW1H OET

    28th April 2014

    Request to the Department of Energy and Climate Change

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

    Dear Madam / Sir,

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    Thank you for your attention to my request for information.

    Regards,

    jo.

  • Failing Narratives : Carbon Culprits

    Posted on March 14th, 2014 Jo No comments

    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 :-

    Here’s some background :-

    http://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 ?

  • The General Lightness of Carbon Pricing

    Posted on February 27th, 2014 Jo 1 comment

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

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

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

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

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

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

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

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

    Subject: Question from your TED talk

    Jo,

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

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

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

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

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

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

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

    Hope some of this helps.

    From: Jo Abbess

    To: Richard A. Sears

    Dear Richard,

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

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

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

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

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

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

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

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

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

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

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

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

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

    I’m thinking very big.

    Regards,

    jo.

  • But Uh-Oh – Those Summer Nights

    Posted on January 20th, 2014 Jo No comments

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

    Nuclear Flower Power

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

    Baseload Should Be History By Now, But…

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

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

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

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

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

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

    Radioactive Waste Disposal Woes

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

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

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

    Politics Is Living In The Past

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

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

    Together in Electric Dreams

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

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

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

    Cornering The Market In Undug Uranium

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

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

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

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

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

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

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

    District Heat Fields

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

    Gas Is The Logical Answer

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

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

    The Age of Your Carbon

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

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

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

    Young Carbon from Seawater

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

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

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

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

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

    How Much Spare Power Will There Be ?

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

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

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

    We could be making a lot of Renewable Gas !

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

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

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

    Choices, choices, choices

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

    Capacity Payments

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

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

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

    Carbon Capture, Carbon Budget

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

  • Making The Sour Sweet

    Posted on January 1st, 2014 Jo No comments

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

  • Hadeo- and Archaeo-Geobiology

    Posted on July 8th, 2013 Jo No comments

    What can deep time teach us ?

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

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

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

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

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

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

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

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

  • Energy Together : I’m just getting warmed up

    Posted on August 27th, 2012 Jo No comments

    The human race – we have to solve energy together. And to do that, we need to harness all our personal, purposeful, positive energies, and let me tell you, personally, I feel electric – and I’m only just getting warmed up.

    So let’s hear less of the nonsense from authoritatively-accredited people who want to put a dampener on green energy, who say that saving energy cannot, simply cannot be done, sigh, sigh, sigh, collective groan. We have so much energy together, we can do this.

    We have the will power, the staying power, the investment power, and we will navigate the obstacles in our path.

    Let’s not waste any more time on expensive trinkets, and iddy-biddy fancies with high unit costs and low compatibility to the future. Yes, I’m talking nuclear power. I’m talking the nobody-really-wants-to-do-it-and-nobody-thinks-it-can-be-cheap-enough-to-work-at-scale Carbon Capture and Storage. And yes, I’m talking carbon markets – tell me again, where are they now ? Oh yes, still in the starting blocks.

    And don’t even start to talk about pricing carbon to me – in this world of rollercoaster, highly volatile energy prices, what on Earth could costing or taxing carbon actually achieve ? And fusion power ? Nah, mate, forget it. It’s been 50 years away for the last 50 years.

    Shale gas, oil from shales, tar sands, coal bed methane collection and underground coal gasification are once-abandoned messy ideas from way back. They’re still messy, and they’re still retro, and they’re not going to get us anywhere. If the United States of America want to completely ruin their lithosphere, well, that’s up to them, but don’t come around here toxifying our aquifers and poisoning our European trees !

    What we need is marine energy, geothermal energy, hydropower, solar power, wind power, and Renewable Gas, because gaseous fuels are so flexible and store-able and can come from many, many processes. And we need the next optimistic generation of leaders to push through the administration ceiling and get green energy policy really rolling, attracting all the green investment will.

    If I were a power plant, I would be cranking out the current and making everything shine very, very brightly just now.

  • Gas in the UK (2)

    Posted on June 14th, 2012 Jo No comments

    …Continued from http://www.joabbess.com/2012/06/12/gas-in-the-uk/

    Questions from the floor

    [Tony Glover]

    …increasing electricification of heat and transport. I was interested in what Doug said about heat. [If energy conservation measures are significant and there is] a significant reduction in gas use for heat…interested in the Minister’s response.

    [Terry ? (Member of PRASEG)]

    I’m interested in gas that would need CCS [Carbon Capture and Storage] [in future] …[since there would be no restriction there would be an] incentive to build new gas in next few years away from CCS-usable infrastructure. Maybe encouraging gas stations over next few years to be built in view of CCS.

    [ ? ]

    [There have been mentions of the] Gas [generation] Strategy and gas storage. Is it your intention to have both in the Energy Bill ? [Need to improve investor confidence.]

    [Charles Hendry MP] I’m more confident than Doug on CHP…[in respect of energy conservation we will begin to increase our use of] CHP [Combined Heat and Power], geothermal energy, don’t need District Heating. I think we’ll see more people switch to electric heating. The likely pricing on gas will mean people have to look at other sources – such as localised heat storage, intelligent ways to produce hot water and heat in their homes […for example, a technology to store heat for several days…] The first [new gas power] plants will be where they are already consented – where originally coal plants – need to have identified in advance – no new plant is consented unless…We’ve asked Ofgem to ask re securing gas supplies. If we can stretch out the tail of North Sea gas – can stretch it out 30 – 40 years […] technology […] Centrica / Norway […] develop contracts […] Is there a role for strategic storage [Centrica asking] […] Buying and selling at the wrong price (like the gold) [widespread chuckling in the room]. Some of it may not need legislation. Gas Strategy will be published before the Energy Bill.

    [David Cox] Get very nervous about gas storage. Don’t think there’s a need to put financial incentives in place to increase gas storage. We think the hybrid gas market is successful – a market and regulatory framework – [gas storage incentives] could damage.

    [Doug Parr] I’m not downbeat because I want to be downbeat on heat. [Of all the solutions proposed none of them show] scaleability, deliverability. I’d love that to come true – but will it ? […] Heat pumps ? Biogas is great but is it really going to replace all that gas ? If we’re going to be using gas we need to make the best use of it […] Issues around new plant / replacement – all about reducing risks no exposing ourselves to [it] – security of supply, climate risks, issues about placement [siting of new plant]. If CCS can really be made to work – it’s a no-brainer – do we want all that carbon dioxide in the atmosphere or … ? Our entire policy becomes dependent on a technology that hasn’t even been demonstrated. Other technologies that people thought were great – years later they still haven’t arrived [for example, rooftop wind turbines]. If we say CCS is the only way it’s going to work – what’s Plan B ? We are going to use [fossil fuels] – should not become wholly dependent on technology not yet demonstrated.

    [Alan Whitehead] Perhaps people should be asked – which would you prefer – a CHP / DH [Combined Heat and Power / District Heating] plant in the valley here, or a couple of wind turbines on that hill ? That would [shake things up].

    Questions from the floor

    [ X ? ] See […] as the ultimate destination. Most important – gas can be made zero carbon – not pie in the sky. 1. Start contributions of carbon-neutral gas and 2. will need far less if [we act] like Japan – force installation of microCHP. Their aim is to do same as for washing machines [bring prices down – make widely available for the home]. MicroCHP [with] heat pumps – reduction as good as decarbonising gas or electricity. But can also decarbonise gas.

    [ X ? ] The Minister mentioned the importance of CHP but recently dropped […] mandate. If CHP so important what measures is the Government taking to ensure its installation ?

    [ X ? ] Electricity is a rubbish fuel for heating buildings – very peaky load – need something cheap to store, cheap to […]. Fits very well with forcing down demand. Where we’re getting our gas from. At the moment our waste is being incinerated. For a cheap additional cost, where currently incinerating we can do anaerobic digestion [AD], producing a fungible asset – the gas – can gradually decarbonise our grid.

    [ Thomas Grier ? ] …a decision [?] of London – CHP in London over the next few years. If we want to use electricity for heat, we need to reinforce the electricity grid [by 60% to 90% ?] In rural situations – use electrical heating. In urban, use decarbonised energy. [This model projection] shows the gas grid disappearing – it will collapse at some point if all we have on the gas grid is cooking.

    [ X ? ] …[encouraged CHP then a few days later] stood up then said all support [removed ?] for CHP next year. A Heat Strategy that said there is enormous [scope / potential] for CHP. We want to see gas, we want to see efficiency. Are we moving towards […] without it they won’t build it.

    [David Cox] Microgeneration – couldn’t get it down economically. Reliability [issues]. Full supporter of biogas – AD got a contribution to make – but never more than 5% – no matter how much [we crack it]. Electricity is not very good for heating – but how to we decarbonise the heat sector ? Always been an advocate of CHP. Government need to do more incentivising of that.

    [Charles Hendry MP] Innovation and invention […] Government can’t support all emerging technologies. Best brains around the world [are working on] how we move fundamentally in a low carbon direction. On the waste hierarchy – burning of waste should be the final stage – finding a better use for it. [I visited] the biggest AD plant in Europe in Manchester – biogas and electricity generation. We are seeing Local Authorities taking a more constructive long-term view on how to manage waste. CHP – we all want to see more of it – to what extent does it need support ? That depends on whether new build – building a community around it. [By comparison, urban retrofitting is probably too expensive] Iceland [took the decision and] retrofitted almost every home – I’m now more convinced than before. What is the right level of subsidy and what makes good economic case ?

    [Doug] We do keep missing opportunities. [For example in Wales, Milford Haven, the new Combined Cycle Gas Turbine at the Liquified Natural Gas (LNG) refinery to process the gas] should have been CHP. I am enthusiastic about lots of heat technologies [but the same questions/issues apply] scaleability and deliverability. District heating [DH] – an infrastructure asset ! [Can change priorities about what gets built – for example in Denmark (?)] they’re building large-scale solar farms to top up the DH. In the Treasury’s infrastructure plan [see DH could be…] Heat is the poor relation in energy debate. Other networks have been identified in the National Policy Statements (NPS) – but not heat.

    [ Leonie Green, Renewable Energy Association ] [I must] defend heat pumps. In Sweden 90% of new builds [hav e heat pumps ?] – heat pump efficiency is a function of the energy-efficiency of the building […] Just on AD – National Grid report said it could provide 50% [of the nation’s supply. Our members think] that’s a bit too high – we think 25%. My question is really about the benefits. We are hearing anxiety about costs, but it’s piecemeal on benefits. We’ve been strong on jobs, balance of trade, exports [all benefits of renewable energy investment and deployment]. Pleased to see DECC put out [report from] Oxford Economics [on the] wider economic benefits. How can we get more and more balance in reports. [An example] Deutsche Bank renewable generation opportunities.

    [ ? ] We would also support more than 5% from renewable gas – also about hydrogen – we used to do it when it was town gas – why not again ? As regards injecting biomethane/biogas from AD into the National Grid [last year ? to this year ?] 130 enquiries to connect AD to our network – none have progressed. Please sort these [registrations] out.

    [ ? ] Minister, we’re not expecting you to fund all technologies – we need some logic – especially with transport. The Government doesn’t recognise the difference between Renewable Natural Gas if used in transport and fossil fuels. Would be simple – a tax on gas if used in a vehicle. What’s the problem over […] ?

    [Colin Snape, University of Nottingham] We are looking at reducing the costs of carbon capture – we have a section of PhDs… One other gas source not mentioned – gas from underground gasification of coal [UCG]. In UK […] 2 billion tonners of coal – slightly offshore – on the energy coast of the UK – where all the action is on CCS – obviously UCG needs to be coupled with CCS to be carbon neutral. Would [be operational] in a very short time period […incentives…]. Significant proportion of UK needs.

    [ ? ] What is the purpose of the Gas Strategy ? Shale gas isn’t a miracle. The “Golden Age of Gas” [report by the International Energy Agency (IEA)] doesn’t mean cheap gas, because [it will be put to] lots of uses. Renewable electricity and nuclear are not going to come until the 2020s. How do we avoid building loads of gas generation that is not necessary after that time ? What’s the role of mothballing (relatively cheap to bring CCGT out of mothballs comparing to build new). No sign of reduction in electricity demand reduction – therefore there will be high gas use.

    [ Doug Parr ] On UCG, the IEA had two scenarios in the “Golden Age of Gas” – both took us over 3.5 degrees Celsius [in additional global warming]. Even if there is unconventional gas sources, still a huge danger of going down the road of unrestrained gas use. What is the alternative ? We should not end up becoming dependent on gas. Should not build gas to fill a short-term hole – they will lobby for their own interests – to keep open.

    [ David Cox ] CCGTs won’t be built without guarantees greater than 20 years. Also renewable energy might not provide in the way that we hope. The CCC report – what caused the rise in energy prices ? The wholesale gas price – not renewable energy, green policies. However, that was slightly dishonest – the counter-factual was […] renewable energy significantly still more expensive than fossil fuel there. Until we can get costs of renewable energy down to the prices of fossil fuels… [The industry] don’t give the impression [they will build] on the basis of short-term need. Gas isn’t clean, I admit that […] CCS – that will work.

    [Charles Hendry MP] A lot comes back to a need for a balanced approach – carbon targets and security of supply. If you haven’t sorted out security of supply, the electorate will not give permission to go low carbon. Gas is a hedging fuel currently but don’t know where costs going over time. As a politician, I like pipelines – know where it’s going (not like LNG, where there was limited use of new LNG import plant). If we want Scandinavian gas, we need security of demand to build the new pipeline. How we deal with issues of biomethane – in 2 years – need to make more progress. Some of these [techologies] will be gamechangers – some, look back in a couple of years… [Need a] permissive framework to allow a lot of ideas and technologies. There is no source of energy that hasn’t required subsidy in early days. Fanciful to suggest new forms of energy can come through without support. The letters we get [from the public, from constituents] are on vehicle fuel costs, not how much their gas bill went up last winter…

    Official end of meeting

    A gaggle of people gathered in the hallway to discuss some items further.

    The Electricity Market Reform (EMR) was generally criticised – as it contains measures likely to specifically benefit nuclear power. Electricite de France was identified as very involved. The Government had said “no nuclear subsidy”, but the EMR measures are equivalent to hidden subsidies.

    The Levy Cap was criticised as it would disturb investor confidence – if several nuclear reactors came on-stream in 10 years time, in the same year, they would eat up the whole subsidy budget for that year – and other technologies would lose out. If was felt that a number of the EMR proposals were “blunt instruments”, not overcoming shortcomings of former levies and subsidies.

    Although the EMR was designed to addressed economic fears, it wasn’t assisting with financing risks – if anything it was adding to them. Rates of return have to be guaranteed for loans to be made – chopping and changing subsidies doesn’t allow for that.

    Leonie Green said that the REA members don’t like the Premium Feed-in-Tariff (FiT). She also said later that they were not pleased about the cuts in support for AD.

    Since my personal interest is in using Renewable Gas of various sources (including Biomethane / Biogas) to displace Natural Gas from the gas grid, I spoke with various people about this informally (including a woman I met on the train on my way home – who really got the argument about decarbonising gas by developing Renewable Gas, and using that to store excess renewable electricity, and use it as backup for renewable electricity. Although she did say “it won’t be done if it won’t confer benefits”.). One of the key elements for developing Renewable Gas is to create a stream of Renewable Hydrogen, produced in a range of ways. Somebody asked me what the driver would be for progress in Renewable Hydrogen production ? I said the “pull” was supposed to be the fabled “Hydrogen Economy” for transport, but that this isn’t really happening. I said the need for increased sources of renewably-sourced gas will become progressively clear – perhaps within a decade.

    One of the persons present talked about how they think the Government is now coming out of the nuclear dream world – how only a few of the proposed new reactors will get built in the next decade – and how the Government now need to come up with a more realistic scenario.

    It was mentioned that is appears that the Biogas technologies are going to have the same treatment as solar photovoltaics – some sort of subsidies at the start – which get cut away far too early – before it can stand on its own two feet. This was said to be the result of an underlying theory that only a fixed amount of money should be used on launching each new technology – with no thought to continuity problems – especially as regards investment and loan structures.

  • Academic Freedom #5 : More Natural Gas power stations is a Good Thing

    Posted on March 19th, 2012 Jo 4 comments

    Energy policy in the United Kingdom is a constant battle. A number of environmental commentators and campaign groups are up in arms about the Department of Energy and Climate Change (DECC). Again.

    Somebody with influence should have a quiet word with DECC about their public relations – they seem intent on leading people a merry dance about their true policy intentions – and then blasting everybody with piecemeal pronouncements, without giving the concerned public the full picture.

    Personally, I think the strategy of building new Natural Gas-fired power plants is rather good. Yes, I will explain why. But first I will cover some of the complaints.

  • Carbon Capture and Syngas

    Posted on November 16th, 2011 Jo No comments

    Back in the 1970s they were expecting global cooling – of the economy. There were oil shocks and shocking prices, and petrochemists beavered away, sweating over test tubes the size of football fields, whisking up synthetic fuels.

    It was not the first time that the world had tried to synthesise liquid vehicle fuel. Hitler famously did it during the Second World War, and had it not been for Bergius and Fischer-Tropsch, Nazi Germany would have collapsed much sooner under the anvil of global economic sanctions. I mean, the history books insist the multi-pronged military assault was responsible for the Victory in Europe, but the final push would never have succeeded without the suspension of energy trade.

    Various syngas and synfuel projects have continued in various places, mostly America, and although the first plants used coal and Natural Gas to make other things, these days the emphasis is on biomass.

    We can expect to see a dramatic rise in the amount of Biogas and Bio-syngas produced over the next few decades, along with renewably-sourced hydrogen. It will all get fed into the global syngas refineries, and out will pop power, vehicle fuel and chemistry.

  • Renewable Gas : Balanced Power

    Posted on November 5th, 2011 Jo 1 comment

    People who know very little about renewable and sustainable energy continue to buzz like flies in the popular media. They don’t believe wind power economics can work. They don’t believe solar power can provide a genuine contribution to grid capacity. They don’t think marine power can achieve. They would rather have nuclear power. They would rather have environmentally-destructive new oil and gas drilling. They have friends and influence in Government. They have financial clout that enables them to keep disseminating their inaccuracies.

    It’s time to ditch the pundits, innuendo artists and insinuators and consult the engineers.

    Renewable Gas can stand in the gap – when the wind doesn’t blow or the sun doesn’t shine and the grid is not sufficiently widespread and interconnected enough to be able to call on other wind or solar elsewhere.

    Renewable Gas is the storing of biologically-derived and renewably-created gases, and the improving of the gases, so that they can be used on-demand in a number of applications.

    This field of chemical engineering is so old, yet so new, it doesn’t have a fixed language yet.

    However, the basic chemistry, apart from dealing with contaminants, is very straight-forward.

    When demand for grid electricity is low, renewable electricity can be used to make renewable hydrogen, from water via electrolysis, and in other ways. Underused grid capacity can also be used to methanate carbon-rich biologically-derived gas feedstocks – raising its stored energy.

    Then when demand for grid electricity is high, renewable gas can be used to generate power, to fill the gap. And the flue gases from this combustion can be fed back into the gas storage.

    Renewable gas can also be biorefined into vehicle fuels and other useful chemicals. This application is likely to be the most important in the short term.

    In the medium-term, the power generation balance that renewable gas can offer is likely to be the most important application.

    Researchers are working on optimising all aspects of renewable gas and biorefinery, and businesses are already starting to push towards production.

    We can have a fully renewable energy future, and we will.
