"Carbon Capture...Another Great Green Scam

by George Monbiot

...The government seeks to bamboozle us by arguing that the new power stations will be “CCS ready”, meaning that one day, in theory, they could be retrofitted with the necessary equipment. But even this turns out to be untrue. In January, Greenpeace obtained an exchange of emails between E.ON, the company hoping to build the new plant - yes, the same E.ON that broadcasts footage of fluttering sycamore keys, suggesting that its dirty old habits have gone with the wind - and Gary Mohammed, the civil servant drawing up the planning conditions.

Mohammed begins by sending an email of such snivelling obsequiousness that you can almost smell the fear on it. “Drafting the conditions for Kingsnorth. If possible I would like to cover CCS … I admit this suggested condition could be without justification and premature but no harm in trying to gauge your opinion.” (This “suggested condition” was actually government policy. Who’s running this country?) E.ON replied by claiming that the secretary of state “has no right to withhold approval for conventional plant” (in fact he has every right). All it would allow the government to specify was that the potential for CCS “will be investigated”. Mohammed wrestled with his conscience for all of six minutes before replying. “Thanks. I won’t include. Hope to get the set of draft conditions out today or tomorrow.”

This exchange took place in mid-January, a few days before the European commission published a proposed directive specifying that all new coal-fired stations must be CCS ready. Mohammed must have known that he was helping E.ON to win approval for the plant before the directive comes into force next year.

You might by now be beginning to derive the impression that carbon capture and storage is not the green panacea ministers have suggested. But you haven’t heard the half of it. Even if it does become a viable means of disposing of carbon dioxide, new figures suggest that it’s likely to enhance rather than reduce our total emissions.

For the companies bidding for contracts to bury the gas, one technique is more attractive than the others. This is to pump it into declining oil fields. The gas dissolves into the remaining oil, reducing its viscosity and pushing it into the production wells. It’s called enhanced oil recovery (EOR). The oil the companies sell offsets some of the costs of carbon storage.

A few weeks ago, the green thinker Jim Bliss roughly calculated the environmental costs of this technique. He used as his case study the scheme BP proposed but abandoned last year for pumping CO2 into the Miller Field off the coast of Scotland. It would have buried 1.3m tonnes of CO2 and extracted 40m barrels of oil. Taking into account only the four major fuel products, Bliss worked out that the total carbon emissions would outweigh the savings by between seven and 15 times.

So has the government ruled out enhanced oil recovery? Not a bit of it. Its memo about the demonstration project says that Hutton’s department “will want to ensure that the treatment of EOR and non-EOR projects are dealt with on a level playing-field basis”. Another document suggests that it favours this technique: enhanced oil recovery will lead to “increased energy security, domestic revenue and employment”. But, the government notes, this will have to happen before the North Sea’s oil infrastructure is dismantled. “Now is the perfect opportunity to realise the significant opportunities offered by CCS.”

Like biofuels and micro wind turbines, carbon capture and storage turns out to be another great green scam. It will come too late to prevent runaway climate change; the government has no intention of enforcing it; and even if it had, the technique is likely to boost our carbon emissions...
