Volatile crude petroleum oil commodity prices over the last decade have played some undoubted havoc with oil and gas company strategy. High crude prices have pushed the choice of refinery feedstocks towards cheap heavy and immature gunk; influenced decisions about the choices for new petrorefineries and caused ripples of panic amongst trade and transport chiefs : you can’t keep the engine of globalisation ticking over if the key fuel is getting considerably more expensive, and you can’t meet your carbon budgets without restricting supplies.
Low crude commodity prices have surely caused oil and gas corporation leaders to break out into the proverbial sweat. Heavy oil, deep oil, and complicated oil suddenly become unprofitable to mine, drill and pump. Because the economic balance of refinery shifts. Because low commodity prices must translate into low end user refined product prices.
There maybe isn’t an ideal commodity price for crude oil. All the while, as crude oil commodity prices jump around like a medieval flea, the price of Natural Gas, and the gassy “light ends” of slightly unconventional and deep crude oil, stay quite cheap to produce and cheap to use. It’s a shame that there are so many vehicles on the road/sea/rails that use liquid fuels…all this is very likely to change.
Shell appear to be consolidating their future gas business by buying out the competition. Hurrah for common sense ! The next stage of their evolution, after the transition of all oil applications to gas, will be to ramp up Renewable Gas production : low carbon gas supplies will decarbonise every part of the economy, from power generation, to transport, to heating, to industrial chemistry.
This is a viable low carbon solution – to accelerate the use of renewable electricity – wind power and solar principally – and at the same time, transition the oil and gas companies to become gas companies, and thence to Renewable Gas companies.
I was in a meeting today held at the Centre for European Reform in which Shell’s Chief Financial Officer, Simon Henry, made two arguments to absolve the oil and gas industry of responsibility for climate change. He painted coal as the real enemy, and reiterated the longest hand-washing argument in politics – that Shell believes that a Cap and Trade system is the best way to suppress carbon dioxide emissions. In other words, it’s not up to Shell to do anything about carbon. He argued that for transportation and trade the world is going to continue to need highly energy-dense liquid fuels for some time, essentially arguing for the continuation of his company’s current product slate. He did mention proudly in comments after the meeting that Shell are the world’s largest bioethanol producers, in Brazil, but didn’t open up the book on the transition of his whole company to providing the world with low carbon fuels. He said that Shell wants to be a part of the global climate change treaty process, but he gave no indication of what Shell could bring to the table to the negotiations, apart from pushing for carbon trading. Mark Campanale of the Carbon Tracker Initiative was sufficiently convinced by the “we’re not coal” argument to attempt to seek common cause with Simon Henry after the main meeting. It would be useful to have allies in the oil and gas companies on climate change, but it always seems to be that the rest of the world has to adopt Shell’s and BP’s view on everything from policy to energy resources before they’ll play ball.
During the meeting, Mark Campanale pointed out in questions that Deutsche Bank and Goldman Sachs are going to bring Indian coal to trade on the London Stock Exchange and that billions of dollars of coal stocks are to be traded in London, and that this undermines all climate change action. He said he wanted to understand Shell’s position, as the same shareholders that hold coal (shares), hold Shell. I think he was trying to get Simon Henry to call for a separation in investment focus – to show that investment in oil and gas is not the same as investing in Big Bad Coal. But Simon Henry did not bite. According to the Carbon Tracker Initiative’s report of 2013, Unburnable Carbon, coal listed on the London Stock Exchange is equivalent to 49 gigatonnes of Carbon Dioxide (gtCO2), but oil and gas combined trade shares for stocks equivalent to 64 gtCO2, so there’s currently more emissions represented by oil and gas on the LSX than there is for coal. In the future, the emissions held in the coal traded in London have the potential to amount to 165 gtCO2, and oil and gas combined at 125 gtCO2. Despite the fact that the United Kingdom is only responsible for about 1.6% of direct country carbon dioxide emissions (excluding emissions embedded in traded goods and services), the London Stock Exchange is set to be perhaps the world’s third largest exchange for emissions-causing fuels.
Here’s a rough transcript of what Simon Henry said. There are no guarantees that this is verbatim, as my handwriting is worse than a GP’s.
[Simon Henry] I’m going to break the habit of a lifetime and use notes. Building a long-term sustainable energy system – certain forces shaping that. 7 billion people will become 9 billion people – [many] moving from off-grid to on-grid. That will be driven by economic growth. Urbanisation [could offer the possibility of] reducing demand for energy. Most economic growth will be in developing economies. New ways fo consuming energy. Our scenarios – in none do we see energy not growing materially – even with efficiencies. The current ~200 billion barrels of oil equivalent per day today of energy demand will rise to ~400 boe/d by 2050 – 50% higher than today. This will be demand-driven – nothing to do with supply…
[At least one positive-sounding grunt from the meeting – so there are some Peak Oil deniers in the room, then.]
[Simon Henry] …What is paramount for governments – if a threat, then it gets to the top of the agenda. I don’t think anybody seriously disputes climate change…
[A few raised eyebrows and quizzical looks around the table, including mine]
[Simon Henry] …in the absence of ways we change the use of energy […] Any approach to climate change has got to embrace science, policy and technology. All three levers must be pulled. Need a long-term stable policy that enables technology development. We think this is best in a market mechanism. […] Energy must be affordable at the point of use. What we call Triple A – available, acceptable and affordable. No silver bullet. Develop in a responsible way. Too much of it is soundbite – that simplifies what’s not a simple problem. It’s not gas versus coal. [Although, that appeared to be one of his chief arguments – that it is gas versus coal – and this is why we should play nice with Shell.]
1. Economy : About $1.5 to $2 trillion of new money must be invested in the energy industry each year, and this must be sustained until 2035 and beyond. A [few percent] of the world economy. It’s going to take time to make [massive changes]. […] “Better Growth : Better Climate” a report on “The New Climate Economy” by the Global Commission on the Economy and Climate, the Calderon Report. [The world invested] $700 billion last year on oil and gas [or rather, $1 trillion] and $220 – $230 billion on wind power and solar power. The Calderon Report showed that 70% of energy is urban. $6 trillion is being spent on urban infrastructure [each year]. $90 trillion is available. [Urban settings are] more compact, more connected, there’s public transport, [can build in efficiencies] as well as reducing final energy need. Land Use is the other important area – huge impact on carbon emissions. Urbanisation enables efficiency in distributed generation [Combined Heat and Power (CHP)], [local grids]. Eye-popping costs, but the money will be spent anyway. If it’s done right it will [significantly] reduce [carbon emissions and energy demand]…
2. Technology Development : Governments are very bad at picking winners. Better to get the right incentives in and let the market players decide [optimisation]. They can intervene, for example by [supporting] Research and Development. But don’t specify the means to an end…The best solution is a strong predictable carbon price, at $40 a tonne or more or it won’t make any difference. We prefer Cap and Trade. Taxes don’t actually decrease carbon [emissions] but fundamentally add cost to the consumer. As oil prices rose [in 2008 – 2009] North Americans went to smaller cars…Drivers [set] their behaviour from [fuel] prices…
[An important point to note here : one of the reasons why Americans used less motor oil during the “Derivatives Bubble” recession between 2006 and 2010 was because the economy was shot, so people lost their employment, and/or their homes and there was mass migration, so of course there was less commuter driving, less salesman driving, less business driving. This wasn’t just a response to higher oil prices, because the peak in driving miles happened before the main spike in oil prices. In addition, not much of the American fleet of cars overturned in this period, so Americans didn’t go to smaller cars as an adaptation response to high oil prices. They probably turned to smaller cars when buying new cars because they were cheaper. I think Simon Henry is rather mistaken on this. ]
[Simon Henry] …As regards the Carbon Bubble : 65% of the Unburnable fossil fuels to meet the 2 degrees [Celsius] target is coal. People would stuggle to name the top five coal companies [although they find it easy to name the top five oil and gas companies]. Bearing in mind that you have to [continue to] transport stuff [you are going to need oil for some time to come.] Dealing with coal is the best way of moving forward. Coal is used for electricity – but there are better ways to make electricity – petcoke [petroleum coke – a residue from processing heavy and unconventional crude oil] for example…
[Simon Henry] …It will take us 30 years to get away entirely from coal. Even if we used all the oil and gas, the 2 degrees [Celsius] target is still possible…
3. Policy : We tested this with the Dutch Government recently – need to create an honest dialogue for a long-term perspective. Demand for energy needs to change. It’s not about supply…
[Again, some “hear hears” from the room from the Peak Oil and Peak Natural Gas deniers]
[Simon Henry] …it’s about demand. Our personal wish for [private] transport. [Not good to be] pushing the cost onto the big bad energy companies and their shareholders. It’s taxes or prices. [Politicians] must start to think of their children and not the next election…
…On targets and subsidies : India, Indonesia, Brazil […] to move on fossil fuel subsidies – can’t break the Laws of Economics forever. If our American friends drove the same cars we do, they’d reduce their oil consumption equivalent to all of the shale [Shale Gas ? Or Shale Oil ?]… Targets are an emotive issue when trying to get agreement from 190 countries. Only a few players that really matter : USA, China, EU, India – close to 70% of current emissions and maybe more in future. The EPA [Environmental Protection Agency in the United States of America] [announcement] on power emissions. China respondedin 24 hours. The EU target on 27% renewables is not [country-specific, uniform across-the-board]. Last week APEC US deal with China on emissions. They switched everything off [and banned traffic] and people saw blue sky. Coal with CCS [Carbon Capture and Storage] we see as a good idea. We would hope for a multi-party commitment [from the United Nations climate talks], but [shows doubt]… To close : a couple of words on Shell – have to do that. We have only 2% [of the energy market], but we [hope we] can punch above our weight [in policy discussions]. We’re now beginning to establish gas as a transport fuel. Brazil – low carbon [bio]fuels. Three large CCS projects in Canada, EU… We need to look at our own energy use – pretty trivial, but [also] look at helping our customers look at theirs. Working with the DRC [China]. Only by including companies such as ourselves in [climate and energy policy] debate can we get the [global deal] we aspire to…
[Question from the table, Ed Wells (?), HSBC] : Green Bonds : how can they provide some of the finance [for climate change mitigation and adaptation] ? The first Renminbi denominated Green Bond from [?]. China has committed to non-fossil fuels. The G20 has just agreed the structure on infrastructure – important – not just for jobs and growth – parallel needs on climate change. [Us at HSBC…] Are people as excited about Green Bonds as we are ?
[Stephen Tindale] Yes.
[Question from the table, Anthony Cary, Commonwealth Scholarship Commission] …The key seems to be pricing carbon into the economy. You said you preferred Cap and Trade. I used to but despite reform the EU Emissions Trading Scheme (EU ETS) – [failures and] gaming the system. Tax seems to be a much more solid basis.
[Simon Henry] [The problem with the ETS] too many credits and too many exemptions. Get rid of the exemptions. Bank reserve of credits to push the price up. Degress the number of credits [traded]. Tax : if people can afford it, they pay the tax, doesn’t stop emissions. In the US, no consumption tax, they are very sensitive to the oil price going up and down – 2 to 3 million barrels a day [swing] on 16 million barrels a day. All the political impact on the US from shale could be done in the same way on efficiency [fuel standards and smaller cars]. Green Bonds are not something on top of – investment should be financed by Green Bonds, but investment is already being done today – better to get policy right and then all investment directed.
[Question from the table, Kirsten Gogan, Energy for Humanity] The role of nuclear power. By 2050, China will have 500 gigawatts (GW) of nuclear power. Electricity is key. Particularly coal. Germany is building new coal as removing nuclear…
[My internal response] It’s at this point that my ability to swallow myths was lost. I felt like shouting, politely, across the table : ACTUALLY KIRSTEN, YOU, AND A LOT OF OTHER PEOPLE IN THE ROOM ARE JUST PLAIN WRONG ON GERMANY AND COAL.
[Kirsten Gogan]…German minister saying in public that you can’t phase out nuclear and coal at the same time. Nuclear is not included in that conversation. Need to work on policy to scale up nuclear to replace coal. Would it be useful to have a clear sectoral target on decarbonising – 100% on electricity ?
[Stephen Tindale] Electricity is the least difficult of the energy sectors to decarbonise. Therefore the focus should be on electricity. If a target would help (I’m not a fan) nuclear certainly needs to be a part of the discussions. Angela Merkel post-Fukushima has been crazy, in my opinion. If want to boost renewable energy, nuclear power will take subsidies away from that. But targets for renewable energy is the wrong objective.. If the target is keeping the climate stable then it’s worth subsidising nuclear. Subsidising is the wrong word – “risk reduction”.
[Simon Henry] If carbon was properly priced, nuclear would become economic by definition…
[My internal response] NO IT WOULDN’T. A LOT OF NUCLEAR CONSTRUCTION AND DECOMMISSIONING AND SPENT FUEL PROCESSING REQUIRES CARBON-BASED ENERGY.
[Simon Henry] …Basically, all German coal is exempted (from the EU ETS). If you have a proper market-based system then the right things will happen. The EU – hypocrisy at country level. Only [a couple of percent] of global emissions. The EU would matter if it was less hypocritical. China are more rational – long-term thinking. We worked with the DRC. Six differing carbon Cap and Trade schemes in operation to find the one that works best. They are effectively supporting renewable energy – add 15 GW each of wind and solar last year. They don’t listen to NIMBYs [they also build in the desert]. NIMBYism [reserved for] coal – because coal was built close to cities. [Relationship to Russia] – gas replacing coal. Not an accident. Five year plan. They believe in all solutions. Preferably Made in China so we can export to the rest of the world. [Their plans are for a range of aims] not just climate.
[Simon Henry] [in answer to a question about the City of London] We don’t rely on them to support our activities [my job security depends on a good relationship with them]]. We have to be successful first and develop [technological opportunities] [versus being weakened by taxes]. They can support change in technology. Financing coal may well be new money. Why should the City fund new coal investments ?
[Question from the table, asking about the “coal is 70% of the problem” message from Simon Henry] When you talk to the City investors, do you take the same message to the City ?
[Simon Henry] How much of 2.7 trillion tonnes of “Unburnable Carbon” is coal, oil and gas ? Two thirds of carbon reserves is coal. [For economic growth and] transport you need high density liquid fuels. Could make from coal [but the emissions impact would be high]. We need civil society to have a more serious [understanding] of the challenges.
After the discussion, I asked Simon Henry to clarify his words about the City of London.
[Simon Henry] We don’t use the City as a source of capital. 90% is equity finance. We don’t go to the market to raise equity. For every dollar of profit, we invest 75 cents, and pay out 25 cents as dividend to our shareholders. Reduces [problems] if we can show we can reinvest. [ $12 billion a year is dividend. ]
I asked if E&P [Exploration and Production] is working – if there are good returns on investment securing new reserves of fossil fuels – I know that the company aims for a 10 or 11 year Reserves to Production ratio (R/P) to ensure shareholder confidence.
Simon Henry mentioned the price of oil. I asked if the oil price was the only determinant on the return on investment in new E&P ?
[Simon Henry] If the oil price is $90 a barrel, that’s good. At $100 a barrel or $120 a barrel [there’s a much larger profit]. Our aim is to ensure we can survive at $70 a barrel. [On exploration] we still have a lot of things in play – not known if they are working yet… Going into the Arctic [At which point I said I hope we are not going into the Arctic]… [We are getting returns] Upstream is fine [supply of gas and oil]. Deepwater is fine. Big LNG [Liquefied Natural Gas] is fine. Shale is a challenge. Heavy Oil returns could be better – profitable, but… [On new E&P] Iraq, X-stan, [work in progress]. Downstream [refinery] has challenges on return. Future focus – gas and deepwater. [On profitability of investment – ] “Gas is fine. Deepwater is fine.”
[My summary] So, in summary, I think all of this means that Shell believes that Cap and Trade is the way to control carbon, and that the Cap and Trade cost would be borne by their customers (in the form of higher bills for energy because of the costs of buying carbon credits), so their business will not be affected. Although a Cap and Trade market could possibly cap their own market and growth as the sales envelope for carbon would be fixed, since Shell are moving into lower carbon fuels – principally Natural Gas, their own business still has room for growth. They therefore support Cap and Trade because they believe it will not affect them. WHAT THEY DON’T APPEAR TO WANT PEOPLE TO ASK IS IF A CAP AND TRADE SYSTEM WILL ACTUALLY BE EFFECTIVE IN CURBING CARBON DIOXIDE EMISSIONS. They want to be at the negotiating table. They believe that they’re not the problem – coal is. They believe that the world will continue to need high energy-dense oil for transport for some time to come. It doesn’t matter if the oil market gets constrained by natural limits to expansion because they have gas to expand with. They don’t see a problem with E&P so they believe they can keep up their R/P and stay profitable and share prices can continue to rise. As long as the oil price stays above $70 a barrel, they’re OK.
However, there was a hint in what Simon Henry talked about that all is not completely well in Petro-land.
a. Downstream profit warning
Almost in passing, Simon Henry admitted that downstream is potentially a challenge for maintaining returns on investment and profits. Downstream is petrorefinery and sales of the products. He didn’t say which end of the downstream was the issue, but oil consumption has recovered from the recent Big Dip recession, so that can’t be his problem – it must be in petrorefinery. There are a number of new regulations about fuel standards that are going to be more expensive to meet in terms of petroleum refinery – and the chemistry profiles of crude oils are changing over time – so that could also impact refinery costs.
b. Carbon disposal problem
The changing profile of crude oils being used for petrorefinery is bound to cause an excess of carbon to appear in material flows – and Simon Henry’s brief mention of petcoke is more significant than it may first appear. In future there may be way too much carbon to dispose of (petcoke is mostly carbon rejected by thermal processes to make fuels), and if Shell’s plan is to burn petcoke to make power as a solution to dispose of this carbon, then the carbon dioxide emissions profile of refineries is going to rise significantly… where’s the carbon responsiblity in that ?
Sigh. I think I’m going to need to start sending out Freedom of Information requests… Several cups of tea later…

Re: Policy and Strategy for North Sea Natural Gas Fields Depletion
Dear Madam / Sir,
I researching the history of the development of the gas industry in the United Kingdom, and some of the parallel evolution of the industry in the United States of America and mainland Europe.
In looking at the period of the mid- to late- 1960s, and the British decision to transition from manufactured gas to Natural Gas supplies, I have been able to answer some of my questions, but not all of them, so far.
From a variety of sources, I have been able to determine that there were contingency plans to provide substitutes for Natural Gas, either to solve technical problems in the grid conversion away from town gas, or to compensate should North Sea Natural Gas production growth be sluggish, or demand growth higher than anticipated.
Technologies included the enriching of “lean” hydrogen-rich synthesis gas (reformed from a range of light hydrocarbons, by-products of the petroleum refining industry); Synthetic Natural Gas (SNG) and methane-“rich” gas making processes; and simple mixtures of light hydrocarbons with air.
In the National Archives Cmd/Cmnd/Command document 3438 “Fuel Policy. Presented to Parliament by the Minister of Power Nov 1967”, I found discussion on how North Sea gas fields could best be exploited, and about expected depletion rates, and that this could promote further exploration and discovery.
In a range of books and papers of the time, I have found some discussion about options to increase imports of Natural Gas, either by the shipping of Liquified Natural Gas (LNG) or by pipeline from The Netherlands.
Current British policy in respect of Natural Gas supplies appears to rest on “pipeline diplomacy”, ensuring imports through continued co-operation with partner supplier countries and international organisations.
I remain unclear about what official technological or structural strategy may exist to bridge the gap between depleting North Sea Natural Gas supplies and continued strong demand, in the event of failure of this policy.
It is clear from my research into early gas field development that depletion is inevitable, and that although some production can be restored with various techniques, that eventually wells become uneconomic, no matter what the size of the original gas field.
To my mind, it seems unthinkable that the depletion of the North Sea gas fields was unanticipated, and yet I have yet to find comprehensive policy statements that cover this eventuality and answer its needs.
Under the Freedom of Information Act (2000), I am requesting information to answer the following questions :-
1. At the time of European exploration for Natural Gas in the period 1948 to 1965, and the British conversion from manufactured gas to Natural Gas, in the period 1966 to 1977, what was HM Government’s policy to compensate for the eventual depletion of the North Sea gas fields ?
2. What negotiations and agreements were made between HM Government and the nationalised gas industry between 1948 and 1986; and between HM Government and the privatised gas industry between 1986 and today regarding the projections of decline in gas production from the UK Continental Shelf, and any compensating strategy, such as the development of unconventional gas resources, such as shale gas ?
3. Is there any policy or strategy to restore the SNG (Synthetic Natural Gas) production capacity of the UK in the event of a longstanding crisis emerging, for example from a sharp rise in imported Natural Gas costs or geopolitical upheaval ?
4. Has HM Government any plan to acquire the Intellectual Property rights to SNG production technology, whether from British Gas/Centrica or any other private enterprise, especially for the slagging version of the Lurgi gasifier technology ?
5. Has HM Government any stated policy intention to launch new research and development into, or pilot demonstrations of, SNG ?
6. Does HM Government have any clearly-defined policy on the production and use of manufactured gas of any type ? If so, please can I know references for the documents ?
7. Does HM Government anticipate that manufactured gas production could need to increase in order to support the production of synthetic liquid vehicle fuels; and if so, which technologies are to be considered ?
Thank you for your attention to my request for information.
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 :-
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.

Subject: Question from your TED talk
I was looking back over older emails and saw that I had never responded to your note. It arrived as I was headed to MIT to teach for a week and then it got lost. Sorry about that.
Some interesting questions. I don’t know anybody working specifically on wind power to gas options. At one time Shell had a project in Iceland using geothermal to make hydrogen. Don’t know what its status is but if you search on hydrogen and Iceland on the Shell website I’m sure there’s something. If the Germans have power to gas as a real policy option I’d poke around the web for information on who their research partners are for this.
Here are a couple of high level thoughts. Not to discourage you because real progress comes from asking new questions, but there are some physical fundamentals that are important.
Direct air capture of anything using current technology is prohibitively expensive to do at scale for energy. More energy will be expended in capture and synthesis than the fuels would yield.
Gaseous fuels are problematic on their own. Gas doesn’t travel well and is difficult to contain at high energy densities as that means compressing or liquefying it. That doesn’t make anything impossible, but it raises many questions about infrastructure and energy balance. If we take the energy content of a barrel of oil as 1.0, then a barrel of liquefied natural gas is about 0.6, compressed natural gas which is typically at about 3600psi is around 0.3, and a barrel (as a measure of volume equal to 42 US gallons) of natural gas at room temperature and pressure is about 0.0015 (+/-). Also there’s a real challenge in storing and transporting gasses as fuel at scale, particularly motor fuel to replace gasoline and diesel.
While there is some spare wind power potential that doesn’t get utilized because of how the grid must be managed, I expect it is a modest amount of energy compared to what we use today in liquid fuels. I think what that means is that while possible, it’s more likely to happen in niche local markets and applications rather than at national or global scales.
If you haven’t seen it, a nice reference on the potential of various forms of sustainable energy is available free and online here. https://www.withouthotair.com/
Hope some of this helps.

Many thanks for getting back to me. Responses are nice – even if they
are months late. As they say – better late than never, although with
climate change, late action will definitely be unwise, according to an
increasing number of people.
I have indeed seen the website, and bought and spilled coffee on the
book of Professor David MacKay’s “Sustainable Energy Without The Hot
Air” project. It is legendary. However, I have checked and he has only
covered alternative gas in a couple of paragraphs – in notes. By
contrast, he spent a long chapter discussing how to filter uranium out
of seawater and other nuclear pursuits.
Yet as a colleague of mine, who knows David better than I do, said to
me this morning, his fascination with nuclear power is rather naive,
and his belief in the success of Generation III and Generation IV
lacks evidence. Plus, if we get several large carbon dioxide
sequestration projects working in the UK – Carbon Capture and Storage
(CCS) – such as the Drax pipeline (which other companies will also
join) and the Shell Peterhead demonstration, announced today, then we
won’t need new nuclear power to meet our 4th Carbon Budget – and maybe
not even the 5th, either (to be negotiated in 2016, I hear) :-
We don’t need to bury this carbon, however; we just need to recycle
it. And the number of ways to make Renewable Hydrogen, and
energy-efficiently methanate carbon monoxide and carbon dioxide with
hydrogen, is increasing. People are already making calculations on how
much “curtailed” or spare wind power is likely to be available for
making gas in 10 years’ time, and if solar power in the UK is
cranked/ramped up, then there will be lots of juicy cost-free power
ours for the taking – especially during summer nights.
Direct Air Capture of carbon dioxide is a nonsensical proposition.
Besides being wrong in terms of the arrow of entropy, it also has the
knock-on effect of causing carbon dioxide to come back out of the
ocean to re-equilibrate. I recently read a paper by climate scientists
that estimated that whatever carbon dioxide you take out of the air,
you will need to do almost all of it again.
Instead of uranium, we should be harvesting carbon dioxide from the
oceans, and using it to make gaseous and liquid fuels.
Gaseous fuels and electricity complement each other very well –
particularly in storage and grid balancing terms – there are many
provisions for the twins of gas and power in standards, laws, policies
and elsewhere. Regardless of the limitations of gas, there is a huge
infrastructure already in place that can store, pipe and use it, plus
it is multi-functional – you can make power, heat, other fuels and
chemicals from gas. In addition, you can make gas from a range of
resources and feedstocks and processing streams – the key quartet of
chemical gas species keep turning up : hydrogen, methane, carbon
monoxide and carbon dioxide – whether you are looking at the exhaust
from combustion, Natural Gas, industrial furnace producer gas,
biological decomposition, just about everywhere – the same four gases.
Energy transition must include large amounts of renewable electricity
– because wind and solar power are quick to build yet long nuclear
power lead times might get extended in poor economic conditions. The
sun does not always shine and the wind does not always blow (and the
tide is not always in high flux). Since demand profiles will never be
able to match supply profiles exactly, there will always be spare
power capacity that grids cannot use. So Power to Gas becomes the
optimal solution. At least until there are ways to produce Renewable
Hydrogen at plants that use process heat from other parts of the
Renewable Gas toolkit. So the aims are to recycle carbon dioxide from
gas combustion to make more gas, and recycle gas production process
heat to make hydrogen to use in the gas production process, and make
the whole lot as thermally balanced as possible. Yes. We can do that.
Lower the inputs of fresh carbon of any form, and lower the energy
requirements to make manufactured gas.
I met somebody working with Jacobs who was involved in the Carbon
Recycling project in Iceland. Intriguing, but an order of magnitude
smaller than I think is possible.
ITM Power in the UK are doing a Hydrogen-to-gas-grid and methanation
project in Germany with one of the regions. They have done several
projects with Kiwa and Shell on gas options in Europe. I know of the
existence of feasibility reports on the production of synthetic
methane, but I have not had the opportunity to read them yet…
I feel quite encouraged that Renewable Gas is already happening. It’s
a bit patchy, but it’s inevitable, because the narrative of
unconventional fossil fuels has many flaws. I have been looking at
issues with reserves growth and unconventionals are not really
commensurate with conventional resources. There may be a lot of shale
gas in the ground, but getting it out could be a long process, so
production volumes might never be very good. In the USA you’ve had
lots of shale gas – but that’s only been supported by massive drilling
programmes – is this sustainable ?
BP have just finished building lots of dollars of kit at Whiting to
process sour Natural Gas. If they had installed Renewable Gas kit
instead of the usual acid gas and sulfur processing, they could have
been preparing for the future. As I understand it, it is possible to
methanate carbon dioxide without first removing it from the rest of
the gas it comes in – so methanating sour gas to uprate it is a viable
option as far as I can see. The hydrogen sulfide would still need to
be washed out, but the carbon dioxide needn’t be wasted – it can be
made part of the fuel. And when the sour gas eventually thins out,
those now methanating sour gas can instead start manufacturing gas
from low carbon emissions feedstocks and recycled carbon.
A normal, everyday Monday morning at Energy Geek Central. Yes, this is a normal conversation for me to take part in on a Monday morning. Energy geekery at breakfast. Perfect.
Nuclear Flower Power
This whole UK Government nuclear power programme plan is ridiculous ! 75 gigawatts (GW) of Generation III nuclear fission reactors ? What are they thinking ? Britain would need to rapidly ramp up its construction capabilities, and that’s not going to happen, even with the help of the Chinese. (And the Americans are not going to take too kindly to the idea of China getting strongly involved with British energy). And then, we’d need to secure almost a quarter of the world’s remaining reserves of uranium, which hasn’t actually been dug up yet. And to cap it all, we’d need to have 10 more geological disposal repositories for the resulting radioactive spent fuel, and we haven’t even managed to negotiate one yet. That is, unless we can burn a good part of that spent fuel in Generation IV nuclear fission reactors – which haven’t even been properly demonstrated yet ! Talk about unconscionable risk !
Baseload Should Be History By Now, But…
Whatever the technological capability for nuclear power plants to “load follow” and reduce their output in response to a chance in electricity demand, Generation III reactors would not be run as anything except “baseload” – constantly on, and constantly producing a constant amount of power – although they might turn them off in summer for maintenance. You see, the cost of a Generation III reactor and generation kit is in the initial build – so their investors are not going to permit them to run them at low load factors – even if they could.
There are risks to running a nuclear power plant at partial load – mostly to do with potential damage to the actual electricity generation equipment. But what are the technology risks that Hinkley Point C gets built, and all that capital is committed, and then it only runs for a couple of years until all that high burn up fuel crumbles and the reactors start leaking plutonium and they have to shut it down permanently ? Who can guarantee it’s a sound bet ?
If they actually work, running Generation III reactors at constant output as “baseload” will also completely mess with the power market. In all of the scenarios, high nuclear, high non-nuclear, or high fossil fuels with Carbon Capture and Storage (CCS), there will always need to be some renewables in the mix. In all probability this will be rapidly deployed, highly technologically advanced solar power photovoltaics (PV). The amount of solar power that will be generated will be high in summer, but since you have a significant change in energy demand between summer and winter, you’re going to have a massive excess of electricity generation in summer if you add nuclear baseload to solar. Relative to the demand for energy, you’re going to get more Renewable Energy excess in summer and under-supply in winter (even though you get more offshore wind in winter), so it’s critical how you mix those two into your scenario.
The UK Government’s maximum 75 GW nuclear scenario comprises 55 GW Generation III and 20 GW Generation IV. They could have said 40 GW Gen III to feed Gen IV – the spent fuel from Gen III is needed to kick off Gen IV. Although, if LFTR took off, if they had enough fluoride materials there could be a Thorium way into Gen IV… but this is all so technical, no MP [ Member of Parliament ] is going to get their head round this before 2050.
The UK Government are saying that 16 GW of nuclear by 2030 should be seen as a first tranche, and that it could double or triple by 2040 – that’s one heck of a deployment rate ! If they think they can get 16 GW by 2030 – then triple that by 10 years later ? It’s not going to happen. And even 30 GW would be horrific. But it’s probably more plausible – if they can get 16 GW by 2030, they can arguably get double that by 2040.
As a rule of thumb, you would need around 10 tonnes of fissionable fuel to kickstart a Gen IV reactor. They’ve got 106 tonnes of Plutonium, plus 3 or 4 tonnes they recently acquired – from France or Germany (I forget which). So they could start 11 GW of Gen IV – possibly the PRISM – the Hitachi thing – sodium-cooled. They’ve been trying them since the Year Dot – these Fast Reactors – the Breeders – Dounreay. People are expressing more confidence in them now – “Pandora’s Promise” hangs around the narrative that the Clinton administration stopped research into Fast Reactors – Oak Ridge couldn’t be commercial. Throwing sodium around a core 80 times hotter than current core heats – you can’t throw water at it easily. You need something that can carry more heat out. It’s a high technological risk. But then get some French notable nuclear person saying Gen IV technologies – “they’re on the way and they can be done”.
Radioactive Waste Disposal Woes
The point being is – if you’re commissioning 30 GW of Gen III in the belief that Gen IV will be developed – then you are setting yourself up to be a hostage to technological fortune. That is a real ethical consideration. Because if you can’t burn the waste fuel from Gen III, you’re left with up to 10 radioactive waste repositories required when you can’t even get one at the moment. The default position is that radioactive spent nuclear fuel will be left at the power stations where they’re created. Typically, nuclear power plants are built on the coast as they need a lot of cooling water. If you are going for 30 GW you will need a load of new sites – possibly somewhere round the South East of England. This is where climate change comes in – rising sea levels, increased storm surge, dissolving, sinking, washed-away beaches, more extreme storms […] The default spent fuel scenario with numerous coastal decommissioned sites with radioactive interim stores which contain nearly half the current legacy radioactive waste […]
Based on the figures from the new Greenpeace report, I calculate that the added radioactive waste and radioactive spent fuel arisings from a programme of 16 GW of nuclear new build would be 244 million Terabequerel (TBq), compared to the legacy level of 87 million TBq.
The Nuclear Decommissioning Authority (NDA) are due to publish their Radioactive Waste Inventory and their Report on Radioactive Materials not in the Waste Inventory at the end of January 2014. We need to keep a watch out for that, because they may have adapted their anticipated Minimum and Maxmium Derived Inventory.
Politics Is Living In The Past
What you hear from politicians is they’re still talking about “baseload”, as if they’ve just found the Holy Grail of Energy Policy. And failed nuclear power. Then tidal. And barrages. This is all in the past. Stuff they’ve either read – in an article in a magazine at the dentist’s surgery waiting room, and they think, alright I’ll use that in a TV programme I’ve been invited to speak on, like Question Time. I think that perhaps, to change the direction of the argument, we might need to rubbish their contribution. A technological society needs to be talking about gasification, catalysis. If you regard yourselves as educated, and have a technological society – your way of living in the future is not only in manufacturing but also ideas – you need to be talking about this not that : low carbon gas fuels, not nuclear power. Ministers and senior civil servants probably suffer from poor briefing – or no briefing. They are relying on what is literally hearsay – informal discussions, or journalists effectively representing industrial interests. Newspapers are full of rubbish and it circulates, like gyres in the oceans. Just circulates around and around – full of rubbish.
I think part of the problem is that the politicians and chief civil servants and ministers are briefed by the “Old Guard” – very often the ex-nuclear power industry guard. They still believe in big construction projects, with long lead times and massive capital investment, whereas Renewable Electricity is racing ahead, piecemeal, and private investors are desperate to get their money into wind power and solar power because the returns are almost immediate and risk-free.
Together in Electric Dreams
Question : Why are the UK Government ploughing on with plans for so much nuclear power ?
1. They believe that a lot of transport and heat can be made to go electric.
2. They think they can use spent nuclear fuel in new reactors.
3. They think it will be cheaper than everything else.
4. They say it’s vital for UK Energy Security – for emissions reductions, for cost, and for baseload. The big three – always the stated aim of energy policy, and they think nuclear ticks all those three boxes. But it doesn’t.
What they’ll say is, yes, you have to import uranium, but you’ve got a 4 year stock. Any war you’re going to get yourselves involved in you can probably resolve in 4 days, or 4 weeks. If you go for a very high nuclear scenario, you would be taking quite a big share of the global resource of uranium. There’s 2,600 TWh of nuclear being produced globally. And global final energy demand is around 100,000 TWh – so nuclear power currently produces around 2.6% of global energy supply. At current rates of nuclear generation, according to the World Nuclear Association, you’ve got around 80 years of proven reserves and probably a bit more. Let’s say you double nuclear output by 2050 or 2040 – but in the same time you might just have enough uranium – and then find a bit more. But global energy demand rises significantly as well – so nuclear will still only provide around 3% of global energy demand. That’s not a climate solution – it’s just an energy distraction. All this guff about fusion. Well.
Cornering The Market In Undug Uranium
A 75 GW programme would produce at baseload 590 TWh a year – divide by 2,600 – is about 23% of proven global uranium reserves. You’re having to import, regardless of what other countries are doing, you’re trying to corner the market – roughly a quarter. Not even a quarter of the market – a quarter of all known reserves – it’s not all been produced yet. It’s still in the ground. So could you be sure that you could actually run these power stations if you build them ? Without global domination of the New British Empire […]. The security issues alone – defending coastal targets from a tweeb with a desire to blow them up. 50 years down the line they’re full of radioactive spent fuel that won’t have a repository to go to – we don’t want one here – and how much is it going to cost ?
My view is that offshore wind will be a major contributor in a high or 100% Renewable Electricity scenario by 2050 or 2060. Maybe 180 GW, that will also be around 600 TWh a year – comparable to that maximum nuclear programme. DECC’s final energy demand 2050 – several scenarios – final energy demand from 6 scenarios came out as between roughly 1,500 TWh a year and the maximum 2,500 TWh. Broadly speaking, if you’re trying to do that just with Renewable Electricity, you begin to struggle quite honestly, unless you’re doing over 600 TWh of offshore wind, and even then you need a fair amount of heat pump stuff which I’m not sure will come through. The good news is that solar might – because of the cost and technology breakthroughs. That brings with it a problem – because you’re delivering a lot of that energy in summer. The other point – David MacKay would say – in his book his estimate was 150 TWh from solar by 2050, on the grounds that that’s where you south-facing roofs are – you need to use higher efficiency triple junction cells with more than 40% efficiency and this would be too expensive for a rollout which would double or triple that 150 TWh – that would be too costly – because those cells are too costly. But with this new stuff, you might get that. Not only the cost goes down, but the coverage goes down. Not doing solar across swathes of countryside. There have always been two issues with solar power – cost and where it’s being deployed.
Uh-Oh, Summer Days. Uh-Oh, Summer Nights
With the solar-wind headline, summer days and summer nights are an issue.
With the nuclear headline, 2040 – they would have up to 50 GW, and that would need to run at somewhere between 75% and 95% capacity – to protect the investment and electric generation turbines.
It will be interesting to provide some figures – this is how much over-capacity you’re likely to get with this amount of offshore wind. But if you have this amount of nuclear power, you’ll get this amount […]
Energy demand is strongly variable with season. We have to consider not just power, but heat – you need to get that energy out in winter – up to 4 times as much during peak in winter evenings. How are you going to do that ? You need gas – or you need extensive Combined Heat and Power (CHP) (which needs gas). Or you need an unimaginable deployment of domestic heat pumps. Air source heat pumps won’t work at the time you need them most. Ground source heat pumps would require the digging up of Britain – and you can’t do that in most urban settings.
District Heat Fields
The other way to get heat out to everyone in a low carbon world – apart from low carbon gas – is having a field-based ground source heat pump scheme – just dig up a field next to a city – and just put in pipes and boreholes in a field. You’re not disturbing anybody. You could even grow crops on it next season. Low cost and large scale – but would need a District Heating (DH) network. There are one or two heat pump schemes around the world. Not sure if they are used for cooling in summer or heat extraction in the winter. The other thing is hot water underground. Put in an extra pipe in the normal channels to domestic dwellings. Any excess heat from power generation or electrolysis or whatever is put down this loop and heats the sub-ground. Because heat travels about 1 metre a month in soil, that heat should be retained for winter. A ground source heat sink. Geothermal energy could come through – they’re doing a scheme in Manchester. If there’s a nearby heat district network – it makes it easier. Just want to tee it into the nearest DH system. The urban heat demand is 150 TWh a year. You might be able to put DH out to suburban areas as well. There are 9 million gas-connected suburban homes – another about 150 TWh there as well – or a bit more maybe. Might get to dispose of 300 TWh in heat through DH. The Green Deal insulation gains might not be what is claimed – and condensing gas boiler efficiencies are not that great – which feeds into the argument that in terms of energy efficiency, you not only want to do insulation, but also DH – or low carbon gas. Which is the most cost-effective ? Could argue reasonable energy efficiency measures are cheapest – but DH might be a better bet. That involves a lot of digging.
Gas Is The Logical Answer
But everything’s already laid for gas. (…but from the greatest efficiency first perspective, if you’re not doing DH, you’re not using a lot of Renewable Heat you could otherwise use […] )
The best package would be the use of low carbon gases and sufficient DH to use Renewable Heat where it is available – such as desalination, electrolysis or other energy plant. It depends where the electrolysis is being done.
The Age of Your Carbon
It also depends on which carbon atoms you’re using. If you are recycling carbon from the combustion of fossil fuels into Renewable Gas, that’s OK. But you can’t easily recapture carbon emissions from the built environment (although you could effectively do that with heat storage). You can’t do carbon capture from transport either. So your low carbon gas has to come from biogenic molecules. Your Renewable Gas has to be synthesised using biogenic carbon molecules rather than fossil ones.
[…] I’m using the phrase “Young Carbon”. Young Carbon doesn’t have to be from plants – biological things that grow.
Well, there’s Direct Air Capture (DAC). It’s simple. David Sevier, London-based, is working on this. He’s using heat to capture carbon dioxide. You could do it from exhaust in a chimney or a gasification process – or force a load of air through a space. He would use heat and cooling to create an updraft. It would enable the “beyond capture” problem to be circumvented. Cost is non-competitive. Can be done technically. Using reject heat from power stations for the energy to do it. People don’t realise you can use a lot of heat to capture carbon, not electricity.
Young Carbon from Seawater
If you’re playing around with large amounts of seawater anyway – that is, for desalination for irrigation, why not also do Renewable Hydrogen, and pluck the Carbon Dioxide out of there too to react with the Renewable Hydrogen to make Renewable Methane ? I’m talking about very large amounts of seawater. Not “Seawater Greenhouses” – condensation designs mainly for growing exotic food. If you want large amounts of desalinated water – and you’re using Concentrated Solar Power – for irrigating deserts – you would want to grow things like cacti for biological carbon.
Say you had 40 GW of wind power on Dogger Bank, spinning at 40% load factor a year. You’ve also got electrolysers there. Any time you’re not powering the grid, you’re making gas – so capturing carbon dioxide from seawater, splitting water for hydrogen, making methane gas. Wouldn’t you want to use flash desalination first to get cleaner water for electrolysis ? Straight seawater electrolysis is also being done.
It depends on the relative quantities of gas concentrated in the seawater. If you’ve got oxygen, hydrogen and carbon dioxide, that would be nice. You might get loads of oxygen and hydrogen, and only poor quantities of carbon dioxide ?
But if you could get hydrogen production going from spare wind power. And even if you had to pipe the carbon dioxide from conventional thermal power plants, you’re starting to look at a sea-based solution for gas production. Using seawater, though, chlorine is the problem […]
Look at the relative density of molecules – that sort of calculation that will show if this is going to fly. Carbon dioxide is a very fixed, stable molecule – it’s at about the bottom of the energy potential well – you have to get that reaction energy from somewhere.
How Much Spare Power Will There Be ?
If you’ve got an offshore wind and solar system. At night, obviously, the solar’s not working (unless new cells are built that can run on infrared night-time Earthshine). But you could still have 100 GWh of wind power at night not used for the power grid. The anticipated new nuclear 40 GW nuclear by 2030 will produce about 140 GWh – this would just complicate problems – adding baseload nuclear to a renewables-inclusive scenario. 40 GW is arguably a reasonable deployment of wind power by 2030 – low if anything.
You get less wind in a nuclear-inclusive scenario, but the upshot is you’ve definitely got a lot of power to deal with on a summer night with nuclear power. You do have with Renewable Electricity as well, but it varies more. Whichever route we take we’re likely to end up with excess electricity generation on summer nights.
In a 70 GW wind power deployment (50 GW offshore, 20 GW onshore – 160 TWh a year), you might have something like 50 to 100 GWh per night of excess (might get up to 150 GWh to store on a windy night). But if you have a 16 GW nuclear deployment by 2030 (125 TWh a year), you are definitely going to have 140 GWh of excess per night (that’s 16 GW for 10 hours less a bit). Night time by the way is roughly between 9pm and 7am between peak demands.
We could be making a lot of Renewable Gas !
Can you build enough Renewable Gas or whatever to soak up this excess nuclear or wind power ?
The energy mix is likely to be in reality somewhere in between these two extremes of high nuclear or high wind.
But if you develop a lot of solar – so that it knocks out nuclear power – it will be the summer day excess that’s most significant. And that’s what Germany is experiencing now.
Choices, choices, choices
There is a big choice in fossil fuels which isn’t really talked about very often – whether the oil and gas industry should go for unconventional fossil fuels, or attempt to make use of the remaining conventional resources that have a lower quality. The unconventionals narrative – shale gas, coalbed methane, methane hydrates, deepwater gas, Arctic oil and gas, heavy oil, is running out of steam as it becomes clear that some of these choices are expensive, and environmentally damaging (besides their climate change impact). So the option will be making use of gas with high acid gas composition. And the technological solutions for this will be the same as needed to start major production of Renewable Gas.
But you still need to answer the balancing question. If you have a high nuclear power scenario, you need maybe 50 TWh a year of gas-fired power generation. If high Renewable Electricity, you will need something like 100 TWh of gas, so you need Carbon Capture and Storage – or low carbon gas.
Even then, the gas power plants could be running only 30% of the year, and so you will need capacity payments to make sure new flexible plants get built and stay available for use.
If you have a high nuclear scenario, coupled with gas, you can meet the carbon budget – but it will squeeze out Renewable Electricity. If high in renewables, you need Carbon Capture and Storage (CCS) or Carbon Capture and Recycling into Renewable Gas, but this would rule out nuclear power. It depends which sector joins up with which.
Carbon Capture, Carbon Budget
Can the Drax power plant – with maybe one pipeline 24 inches in diameter, carrying away 20 megatonnes of carbon dioxide per year – can it meet the UK’s Carbon Budget target ?
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.
Yet again, the fossil fuel companies think they can get away with uncommented public relations in my London neighbourhood. Previously, it was BP, touting its green credentials in selling biofuels, at the train station, ahead of the Olympic Games. For some reason, after I made some scathing remarks about it, the advertisement disappeared, and there was a white blank board there for weeks.
This time, it’s Esso, and they probably think they have more spine, as they’ve taken multiple billboard spots. In fact, the place is saturated with this advertisement. And my answer is – yes, fuel economy is important to me – that’s why I don’t have a car.
And if this district is anything to go by, Esso must be pouring money into this advertising campaign, and so my question is : why ? Why aren’t they pouring this money into biofuels research ? Answer : because that’s not working. So, why aren’t they putting this public relations money into renewable gas fuels instead, sustainable above-surface gas fuels that can be used in compressed gas cars or fuel cell vehicles ?
Are Esso retreating into their “core business” like BP, and Shell, concentrating on petroleum oil and Natural Gas, and thereby exposing all their shareholders to the risk of an implosion of the Carbon Bubble ? Or another Deepwater Horizon, Macondo-style blowout ?
The UK Government appear to have seen the light about their, frankly, rubbish plan to covertly invest in (by hidden subsidies) a spanking new fleet of nuclear power reactors.
Dogged by Electricite de France (EdF) as they have been, with Vincent de Rivaz continuing to proffer his begging bowl with outstretched pleading arms, it just might be that before the Energy Bill is finally announced –
when the Electricity Market Reform (EMR) dust has settled – that this new thinking will have become core solidity.
After all, there are plenty of reasons not to support new nuclear power – apart from the immense costs, the unclear costs, the lack of immediate power generation until at least a decade of concrete has been poured, and so on (and so forth).
Gas is Laughing
It appears that reality has bitten – and that the UK Government are pursuing gas. And they have decided not to hatch their eggs all in one basket. First of all, there’s a love-in with Statoil of Norway :-
Then, there’s the new “South Stream” commitment – the new Azerbaijan-European Union agreement, spelled out in a meeting of the European Centre for Energy and Resource Security (EUCERS) on 12th June at King’s College, London :-
The UK will still be importing Liquified Natural Gas (LNG) from our good old friends in Qatar. Never mind the political interference in the nearby region and the human rights abuses, although NATO could be asked to put a stop to that if Europe needed to bust the regime in order for their energy companies to take ownership of the lovely, lovely gas. I mean, that’s what happened in Iraq and Libya, didn’t it ?
A Fossilised Future
So, despite all the green noises from the UK Government, the underlying strategy for the future (having batted away the nuclear buzzing insects around the corpse of British energy policy), is as Steve Browning, formerly of National Grid says – “gas and air” – with Big Wind power being the commercialisable renewable technology of choice. But not too much wind power – after all, the grid could become unstable, couldn’t it, with too much wind ?
There are several problems with this. First, the commitment to fossil fuels – even Natural Gas with its half the emissions profile of coal – is a risky strategy, despite making sure that supplies are secure in the near term. The reasons for this are geological as well as geopolitical. Natural Gas will peak, and even the UK Government accepts that unconventional gas will not keep fossil gas going forever – even with the “18 years” ultimate recoverable from under Lancashire of shale gas (that’s “18 years” of current gas annual demand – but not all drilled at once – perhaps amounting to about 1.5% of current UK gas supply needs per year, stretched out over 40 years) , and the billion tonnes of coal that can be gasified from under the sea off the east coast of England. As long as Carbon Capture and Storage can work.
Not only will Natural Gas peak and start to decline in the UK, it will also peak and decline in the various other foreign resources the UK is promising to buy. By simple logic – if the North Sea gas began depletion after only 30 years – and this was a top quality concentrated resource – how soon will poorer quality gas fields start depleting ?
Whilst I recognise the sense in making Natural Gas the core strategy of UK energy provision over the next few decades, it can never be a final policy. First off, we need rather more in terms of realistic support for the deployment of renewable electricity. People complained about onshore wind turbines, so the UK Government got into offshore wind turbines, and now they’re complaining at how expensive they are. Then they botched solar photovoltaics policy. What a palaver !
Besides a much stronger direction for increasing renewable electricity, we need to recognise that renewable resources of gas need to be developed, starting now. We need to be ready to displace fossil gas as the fossil gas fields show signs of depletion and yet global demand and growth still show strength. We need to recognise that renewable gas development initiatives need consistent central government financial and enabling policy support. We need to recognise that even with the development of renewable gas, supplies of gas as a whole may yet peak – and so we need to acknowledge that we can never fully decarbonise the energy networks unless we find ways to apply energy conservation and energy efficiency into all energy use – and that this currently conflicts with the business model for most energy companies – to sell as much energy as possible. We need mandates for insulation, efficient fossil fuel use – such as Combined Heat and Power (CHP) and efficient grids, appliances and energy distribution. Since energy is mostly privately owned and privately administered, energy conservation is the hardest task of all, and this will take heroic efforts at all levels of society to implement.
One of the key fears of cryosphere scientists, those who study the cold places on Earth, is a scenario where the permafrost and sub-sea continental shelves around the Arctic Ocean become unstable and start emitting uncontrollable quantities of methane into the atmosphere.
Methane is an important by-product of biological decomposition, and is also found in icy deposits known as clathrates – methane hydrates – estimated to be very widespread in marine and geological deposits.
Although it is short-lived, before breaking down or reacting with other molecules, methane is a powerful greenhouse gas, some 23 or 24 times more potent than carbon dioxide.
An ongoing unfreezing of the sub-zero “Northern Wastes” would set up a constant flow of biological methane into the Arctic sky and so the warming would be continuous – a major risk to attempts to limit climate change – because it could not be controlled by altering mankind’s economic and energy activities.
Reports of high levels of atmospheric methane in the Arctic region in the lastfewmonths have been mangled by the media headline generation machine to raise their urgency value – making them into “news” – and the reaction from most sensible academics and commentators is to downplay talk of a catastrophhic “Methane Burp”.
Yet the data is interesting enough to warrant continued monitoring and explanatory power – for the methane story is complex and shifting. It may be time for alarm bells to ring, however we’re not sure exactly how much data we need to see before we do so.
The long picture for methane in the air is one of hundreds of years of acceleration :-
In the last few decades however, atmospheric methane started to level off :-
However, since around 2007, methane concentrations have been rising once more :-
Following the recent headlines about high methane readings in the Arctic, there have been a number of online discsusions about what it could signify.
Tamino’s Open Mind doesn’t see a dangerous increase in emissions when looking at a seasonally-adjusted selection of data from the World Data Center for Greenhouse Gases and Earth System Research Laboratory (ESRL) flask measurements of methane concentrations at around surface level :-
I asked Giovanni to chart recent measurements from the AIRS project, the Atmospheric InfraRed Sounder on board NASA’s Aqua satellite spacecraft :-
The months December 2011 to January 2012 show a significant peak in methane concentrations in the area 60 degrees North to 90 degrees North.
This peak seen by satellite does not appear to be reflected in the surface measurement charts I asked the online ESRL tool to plot for me :-
What could be causing the satellite reading peaks to be so high relative to the changes in ground-based measurements ? What is happening in the different layers of the atmosphere ?
Has there been some kind of “detonation” of the chemistry of the air above the Arctic, causing peaks in methane concentrations at high altitudes not seen at ground level ?
Do the AIRS readings need adjustment because of unusual pressure and temperature gradients around the Arctic over the boreal (Northern Hemisphere) winter 2011 – 2012 ?
Has there been a rapid release of methane somewhere, such as from an oil and gas production field somewhere in the region ? Will the international greenhouse gas inventories compiled by the United Nations Framework Convention on Climate Change (UNFCCC) Kyoto Protocol nations reveal anything about this ?
Here’s the prime time television where the U. S. Army chief admits that the American military know Iran is engineering at sea – although the General deliberately gets the purpose wrong.
[For an uncorrected transcript of the piece, see below at the end of this post].
He claims that Iran is going to use their engineering to shut the Strait of Hormuz, a major artery of oil transport from the Middle East to the world.
Whereas, in actual fact, Iran has been constructing facilities to mine marine, sub-sea Natural Gas in its territorial waters in the Persian Gulf, and wants to use it to generate electricity to export.
Iran is sitting on Natural Gas – a lot of Natural Gas. And a lot of it is at sea. There have been marine seismic surveys for sub-sea Natural Gas in the Persian Gulf over the last few years, and it seems, other countries have been spying on the Iranian offshore activities.
Clearly, with Iran’s intent to exploit its marine gas, there have been and will be construction ships and construction going on in the Persian Gulf and around the Strait of Hormuz, especially the islands of Kish and Qeshm. This should not be mistaken as a risk to oil shipping. It should not be claimed as indications of Iran seeking to close the Strait of Hormuz in retaliation for economic sanctions.
What is at stake here is no less than Iran’s energy sovereignty – its sovereign right to enjoy the wealth from exploiting its own energy resources.
The international pressure for an end to fossil fuel subsidies would hurt Iranian internal economic development (much like it’s hurting Nigeria, currently), and it would be forced to export oil and Natural Gas – no doubt at low market prices. Iran may end up no better off for trading.
The Iranians bought myths about nuclear power hook, line and sinker, and they believe they have a right to develop civilian atomic energy. Other countries, the United States of America in particular, keep pushing this button and claiming that Iran is heading for developing nuclear weapon capability. This is the most unbelievable accusation since…oh, I don’t know, since the USA accused Iran of a plot for a used car salesman and a Mexican, or something, to kill a Saudi ambassador, which was unadulterated nonsense.
America’s insistence that Iran is a threat because they claim that Iran is working towards constructing nuclear weapons, is so ridiculous, that few seem to have realised it is “deflection” – a propaganda technique to divert you from the real source of tension between the USA and Iran.
What America really doesn’t seem to like is countries like Iran (and Venezuela) making autonomous energy decisions, and creating their own wealth by using their own energy resources in their own way.
Maybe the American war hawks think “Why cannot Iran be more like Iraq, with western oil and Natural Gas companies with discount contracts, crawling over new resources and selling it all abroad ?”
Anyway, what is clear is that the spat between Iran and the USA has nothing to do with nuclear power or idle brinkmanship about controlling the flow of oil as a retaliation against economic sanctions.
Bloomberg : 9 January 2012 : Lara Setrakian reports on the outlook for Iran to close the Strait of Hormuz as Europe prepares to follow tougher U. S. sanctions on the country over its nuclear program and the status of a pipeline that would allow oil from the United Arab Emirates to bypass the waterway. The pipeline has been delayed because of construction difficulties, two people with knowledge of the matter said. Setrakian speaks with Linzie Janis on Bloomberg Television’s “Countdown.”
[Ticker tape reads “AHMADINEJAD TURNS TO CHAVEZ FOR SUPPORT”]
[Linzie Janis] “The Persian Gulf could be closed off to ships altogether, that’s if tensions continue to escalate between Iran and the West. Iranian President Mahmoud Ahmadinejad is due to meet with Venezuelan leader Hugo Chavez later on today as part of a tour of Latin America. He is seeking s”upport” as Iran faces tighter U. S. sanctions over its nuclear program.
[Mahmoud Ahmadinejad in translation] We will discuss the intentions of the arrogant system interfering and having a military presence in other countries. We shall coordinate with our friends in Latin America to address this matter.
[Linzie Janis] Well with the very latest Lara Setrakian joins us with from Dubai
Lara itell it looks like the U. S. and Iran could be on a – – collision course here.
[Lara Setrakian] Well moving closer towards it, as Iran inches towards what the U. S. has called “two red lines” – advanced nuclear enrichment at the underground Fordow facility, and shutting the Strait of Hormuz – something that Iran told the A. P. [Associated Press] they’ll do if the E. U. oil embargo goes through later this month. The highest level U. S. assessment to date – that Iran could shut the Strait that would effectively trigger a military confrontation in the Persian Gulf.
General Martin Dempsey, American Department of Defense, United States Army Joint Chiefs of Staff Chairman] They’ve invested in capabilities that could [scratches nose – a classic sign of lying] in fact for a period of time block the Straits of Hormuz. We’ve invested in capabilities [rocking body slightly from side to side – a classic sign of swagger] to ensure that if that happens [giving a hard, fixed stare] we can, er, defeat that. [Looks down briefly – meaning that this information was a significant reveal] And so, the simple answer [shrugs shoulders to dimiss the concept] is yes, they can block it. Er… [ Looks down and to his right, our left, indicating a recall of something] And of course that is as well…[blinks to conceal the fact that he’s cut something out] we’ve described that as an intolerable act [shrugs shoulders as if to say, those Iranians have got it coming to them] and it’s not just intolerable for us [shakes head from side to side] it’s intolerable to the world [rubs one hand over another, which is a sign of nervousness]. But we would take action and re-open the Straits [shuts lips in beefburger bun clench and nodding as a sign that no more useful information will be forthcoming].
[ Ticker Tape reads : THREATS TO STRAIT OF HORMUZ SHIPPING ]
[Lara Setrakian] Meanwhile it could disrupt the biggest sea lane for the world’s shipped oil, what one analyst called “the ultimate fear in the oil market – it would spike prices”.
[Linzie Janis] So what kind of preparation are you seeing to counter that risk ?
[Lara Setrakian] Well, one of the biggest contigency plans so far has floundered – a pipeline here in the U. A. E. that would run from Abu Dhabi to the Port of Fujairah. It would avoid the Strait. It’s a $3.3 billion dollar project but it’s been delayed – not ready until April at the soonest. And it’s meant to move 1.5 million barrels per day, most of Abu Dhabi’s output, say two days at sea, but the pipeline has been delayed repeatedly by construction issues – one energy analyst Robin Mills pointing also to a pipeline in Saudi Arabia that’s meant to be another backup system [ Ticker Tape reads “FURTHER CONTINGENCY PIPELINES PLANNED”] that could take oil to the Red Sea after 5 million barrels of oil a day capacity and it could be expanded – again, all contigency planning – to keep oil free from any Iranian chokehold in the Persian Gulf.
What’s wrong with this map ? Yes, the same old question. And the answer is again the same – the lack of geographical accuracy in the map reflects the lack of legal accuracy on the part of Israel in appropriating marine Natural Gas that belongs to the Palestinian Gaza Strip.
The map is taken from a new research paper by Brenda Shaffer, of the School of Political Sciences at the University of Haifa, which has been accepted for publication in Energy Policy at some point in the near future :-
When did Colonel Muammar Gaddafi learn of threats from the world’s major oil consumer countries against his rule ? Was it in early 2011 ? Or was it several years earlier ? On the public stage, he has been deliberately reduced to a figure of fun, and his message advising non-aggression and protection from aggression is being lost. He is now a desperate man :-
The documentary evidence shows that America’s business interests often outweigh its political progress. Yet it’s perhaps more concerning that, increasingly, corporate America is at risk of damaging good environmental governance.
With all the talk of free markets in international trade, the Coalition Government in the United Kingdom has felt the pressure to open up the back door to American energy businesses, whose highly-paid sales representatives in slick suits want us to buy their dirty energy projects – just take a look at the upcoming UK Energy Bill and its proposals for Electricity Market Reform.
American companies seem poised to sweep in and take all our public non-subsidy “support” for building new nuclear power plants. Viewers of a sensitive political disposition should look away now as this is a Wikileak :-
The country that brought you the engineering industry that brought you the giant Gulf of Mexico giant oil spill now wants to bring you unsafe deepwater drilling in Britain’s Continental Shelf – and the UK’s new Energy Bill would let them do that without demonstrating any learning from the BP April 2010 fiasco :-
There’s lots of talk in the energy sector and the financial markets about the American shale gas miracle “gamechanger” and how it can be replicated in Europe and across the world, and not enough discussion about the environmental dangers :-
It’s good to talk about local environmental damage from “unconventional” gas, but what’s not being discussed so widely is that these “new” resources of Natural Gas aren’t really very green, and neither are the “traditional” resources – in some cases they’re not much better than coal :-
We know that the Americans always seek to protect the interests of American-owned businesses – and we know they do that for the best of intentions – to keep America wealthy (except it’s really only a few people in America that have any wealth, but anyway…)
Yet I think there should be a limit to how far we have to bend over backwards to accommodate their needs for economic recovery.
To export all their dirty energy technology to Europe is just not helpful, and I think we should say no, no, no.
“Protesters condemn ‘dirty oil’ at World Energy Congress : (AFP) : 14 September 2010 : MONTREAL — Hundreds of protesters demonstrated in the streets of Montreal Sunday, calling for an end to “dirty, risky” oil exploration, ahead of a global gathering of energy experts. A dozen protesters covered in molasses staged a “Black Tide Beach Party,” while dozens of others carried banners that read “Too dirty, too risky, go beyond oil.” A blond baby boy smeared in brown sticky molasses wailed in his activist father’s arms, while protesters used megaphones to slam the provincial Quebec government of Jean Charest for inviting oil companies to the five-day World Energy Congress at the sprawling Palais de Congres. Some 5,000 participants from industry, government and academia, were expected to attend the conference, slated to officially open Sunday evening. The event is expected to tackle global energy issues, such as improving access to energy in the world’s poorer regions and the role of new technologies in ensuring a sustainable energy future. Many protesters directed their anger at BP over a devastating oil spill in the Gulf of Mexico earlier this year. But Julien Vincent, a campaigner for Greenpeace International, said BP was only part of the problem. “British Petroleum is one part of a big industry that’s got an abysmal safety record and an abysmal record in terms of its obligations toward protecting communities,” he told AFP. “You also have oil from Shell dripping out over Nigeria right now. You have oil spills that have taken place in China that have flooded ports,” he added. “The entire industry needs to be told to sit back and listen up.” …”
Unlike the United Kingdom, where political sensibility can quash the most logical enactment of energy policy, plans for progress voiced so tentatively you can bearly feel a ripple, or hear it over the whispering swoosh of a new wind turbine blade, over in Deutschland, what they say, they intend to happen, and they’re making serious proposals about how that’s going to be done :-
“09/07/2010 : Green Visions : Merkel’s Masterplan for a German Energy Revolution : By Stefan Schultz : Giant windparks, insulated buildings, electric cars and a European supergrid: the German government on Monday unveiled an ambitious but vague blueprint to launch a new era of green energy for Europe’s largest economy. SPIEGEL ONLINE has analyzed the plans…”
It appears to be time to wave bye-bye to German coal, incidentally, even as a strong commitment to renewable, sustainable energy is put on the table.
I wish the British Government could take a long hard look at themselves in the mirror of the future and realise what a bunch of dithering duffers they appear to be.
What we need is a proper Energy Policy, chaps, and since you’re in the hot seat you better come up with it. Elected or not, our ministers and officials need to get up out of their deep leather chairs, extinguish their pipes, don their working breeches and get digging for Britain, and I don’t mean Shale Gas or Old Coal.

subject: Climate Week
It was lovely to speak with you today about Climate Week and I’d be grateful if you could pass on the information to the rest of your team.
Climate Week, 21st – 27th March 2011, is a new national occasion on climate change, backed by the Prime Minister, Al Gore and Kofi Annan. During Climate Week, thousands of events will be run by organisations from every part of society to highlight the positive steps being taken to help prevent climate change.
I have attached a document for further information, the document includes a list of supporters of Climate Week, which range from every part of society: from the Chief Fire Officers Association to the Women’s Institute, the Girl Guiding UK to several Regional Development Agencies.
“09/01/2010 : ‘Peak Oil’ and the German Government : Military Study Warns of a Potentially Drastic Oil Crisis : By Stefan Schultz…”
My view on Peak Oil is that it is the tip of the iceberg – and I know that’s a totally inappropriate metaphor.
The art of petrogeology dictates that right on the heels of Peak Oil is Peak Natural Gas, and there is strong evidence for Peak Coal. In the US for example, I understand there is very little good hard anthracite left.
My position is that – since the “conventional” Fossil Fuels are depleting, there are strong moves towards the “unconventionals”, the shale gas, the deepwater oil, the smoky “half peat”, the Lake Baikal hydrates, the frozen subsea wastes of the Arctic [don’t forget the Tar Sands !] and so on. People argue for “stop-gap” energy resources, but they carry with them huge risks not only to the Climate, but also the the Economy with the step-change in EROI/EROEI [Energy Return on Energy Invested – that is – how much energy do you need as input to get energy as output] and the “clean-up” costs.
My take on this is that pretending that Peak Conventionals doesn’t exist leaves a veil in front of most peoples’ minds – they believe in the Power of Technology to supply all their Fossil Fuel needs, now and into the future – it’s just that the actual location and form and dirtiness of these new resources will be different than in the past.
And here’s the rub – we need to encourage people to think about the “alternatives”, or rather, the “solutions”.
The only way forward is Renewable, Sustainable Energy resources, because of Peak Oil, Peak Natural Gas and so on, and if people do not learn about that, they will not understand the privation for most people that will surely come with Peak Conventionals.
We all love the inputs, but what about the outputs ?
Fossil Fuels have been providing an easy life and easy pickings for the citizens and enterprises of the industrialised world for some time.
People love their jet-fuelled lives. One man will move one kilometre from his home to a restaurant in two and a half metric tonnes of steel and glass believing he is admired for his larger-than-car-sized car. He will wear sunshades, and oil-slicked hair (if he has any) and sport a tan from his recent holiday over the ocean. A life of glory and feeling good about himself.
But what about the emissions ? What, indeed, about the environmental devastation at the places the Fossil Fuels (and metal and glass) were mined and refined and manufactured ?
“Pakistan floods: Climate change experts say global warming could be the cause : The world weather crisis that is causing floods in Pakistan, wildfires in Russia and landslides in China is evidence that global warming predictions are correct, according to climate change experts. : By Louise Gray, Environment Correspondent : Published: 10 Aug 2010 : Almost 14 million people have been affected by the torrential rains in Pakistan, making it a more serious humanitarian disaster than the South Asian tsunami and recent earthquakes in Kashmir and Haiti combined. The disaster was driven by a ‘supercharged jet stream’ that has also caused floods in China and a prolonged heatwave in Russia. It comes after flash floods in France and Eastern Europe killed more than 30 people over the summer. Experts from the United Nations (UN) and universities around the world said the recent “extreme weather events” prove global warming is already happening. Jean-Pascal van Ypersele, vice-president of the body set up by the UN to monitor global warming, the Intergovernmental Panel on Climate Change (IPCC), said the ‘dramatic’ weather patterns are consistent with changes in the climate caused by mankind. “These are events which reproduce and intensify in a climate disturbed by greenhouse gas pollution,” he said. “Extreme events are one of the ways in which climatic changes become dramatically visible.”…”
