Coal-fired power stations will lock UK into a high-emissions future, say MPs

The government will come under increased pressure today to ban new coal-fired power stations such as the one planned for Kingsnorth in Kent unless they are equipped to trap and store carbon pollution underground, as a committee of MPs publishes a critical report.
The environmental audit committee urges ministers to make it clear that coal power plants that do not fit carbon capture and storage (CCS) equipment will be closed down. It says the government must set a deadline, after which the operation of unabated coal-fired power stations should not be permitted.
Tim Yeo, chairman of the committee, said: "We cannot afford to develop new coal-fired power stations when we have no guarantee about when they will be fitted with CCS, if at all."
A failure to set such a deadline would make it difficult for the UK to meet carbon-reduction targets, the committee said.
The government is debating whether to allow the German-owned utility E.ON to press ahead with a new coal-fired power station at Kingsnorth in Kent. The company wants to proceed with the scheme, promising to fit CCS later if it can be proved to be technically and financially viable.
Environmentalists see the Kent project as a vital test of the government's green credentials and want Kingsnorth given the go-ahead only if CCS is installed. Greenpeace believes the environmental audit committee's conclusions support its case and leaves the government with its back against the wall.
John Sauven, Greenpeace's executive director, said: "Gordon Brown must now show he has the courage to tackle the threats of energy security, climate change and high energy prices by introducing tough new standards for power stations that limit global-warming emissions. And, in doing so, he must rule out current plans for Kingsnorth."
Last month, David Cameron said a future Conservative government would impose such emissions restrictions, to in effect ban new coal plants without CCS.
Today's report said CCS technology could "contribute significantly to emissions reductions" and could play a decisive role in the battle against global warming. But that progress has been "regrettably slow".
No full-scale CCS project that buries pollution from a power plant has yet been built, though the UK government is running a competition that aims to demonstrate the technology by 2014.
Supporters say the technology could remove 90% of the carbon emissions from coal and will be critical in developing countries such as India and China. However, critics say it is unproven and that governments have underestimated the scale and expense of the vast infrastructure that would be needed.
Even with the promise of CCS, the committee warned that coal should be seen as a last resort in the UK. The committee said the government could be considering a new era of coal-fired power stations because it was the easy option, and warned that such an approach was extremely dangerous.
With no certainty about when the technology will be commercially available, the MPs said, plans to develop new coal-fired power stations would lock the country into a high-emissions future.
Tim Jones, climate policy officer at the World Development Movement, which campaigns against new coal-fired plants, said: "The government should be closing down dirty coal-power stations, not allowing new ones to be built. And the government certainly should not be relying on carbon capture and storage to justify new coal-power stations." Next month's planned climate protest camp will target the Kingsnorth site.
The Royal Society wrote to ministers in April to suggest that new coal-fired power stations were only allowed on the condition that they lose their permit to operate if they failed to capture 90% of carbon dioxide emissions by 2020.
Sir Martin Rees, president of the society, said: "This will give a clear signal to industry and provide the conditions in which the government and industry can work together to take a lead on developing a very valuable technology."
The energy minister, Malcolm Wicks, said he was "pleased" that the environmental audit committee recognised the steps Britain had taken towards developing clean coal technology with the UK carbon capture and storage demonstration project, but insisted that coal was vital for the future.
"We are committed to the development of CCS technology and we intend to be one of the first countries to demonstrate the technology for a coal-fired station on a commercial scale," he said. "Coal is and will remain a vital part of the global energy mix, and this will be the case for many years to come."
