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.
Seriously – where the exoplanet are we at ?
