Clean deadline call on coal power
July 22, 2008
The government should set a deadline for coal-fired power stations to adopt "clean" technologies or close, according to a parliamentary committee.
The Environment Audit Committee says the government is wrong to believe that a carbon market alone will persuade companies to invest in "clean coal".
Its report warns that progress in this area is "extremely disappointing".
A coal-fired station produces about twice as much carbon dioxide as a gas-burning facility of equal power.
The company E.On recently won approval for plans to build new coal-fired plant at Kingsnorth power station in Kent.
The committee heard evidence that five or six other new coal-burning stations may be built in the UK by 2015.
As gas prices rise, generators are increasingly looking to coal as a cheaper and more reliable alternative.
The UK government believes - as do others - that the answer is "clean coal", particularly technologies which capture carbon from the flue gases and store it away in natural underground voids, perhaps under the sea bed.
But the technology is expensive and makes a power station less efficient, increasing the amount of fuel burned by 10-40%.
Market constraints
The government's main strategy is that the EU Emissions Trading Scheme (ETS) will give companies an economic incentive to invest in carbon capture and storage (CCS) when the carbon price rises sufficiently.
But the Environment Audit Committee heard Energy Minister Malcolm Wicks admit this may not happen.
"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," said committee chairman Tim Yeo MP.
"It is absolutely crucial for the government to... tell the industry that carbon capture and storage will be required, and that coal-fired power stations will not be permitted to operate unabated."
The committee says the government must set a date by which companies must have adopted CCS, or face closure of their installations - though it does not suggest which date should be adopted.
Clean coal can be a "fig leaf", it warns, allowing government to claim it is developing a low-emission energy future when in fact there is no certainty that CCS will be introduced.
"Unless there is a dramatic technological development, coal should be seen as the last resort, even with the promise of CCS," the report concludes.
It also has harsh words for the government's strategy of funding a single CCS demonstration facility when several competing technologies could all benefit from investment.
'No approvals'
The Royal Society, the UK's principal scientific academy, endorsed the committee's call for bold leadership, but said the government "appears paralysed".
"The solution is straightforward; consent must only be given for new coal-fired power stations on condition that operating permits are withdrawn if the plant fails to capture 90% of its CO2 emissions by 2020," said the society's president Martin Rees.
Environment groups which are campaigning against the new Kingsnorth units were more outspoken.
"The government should not be relying on CCS - an unproven technology - to justify new coal power stations," said Tim Jones, climate policy officer with the World Development Movement.
"If the government goes ahead with new coal power without CCS, it would be setting the UK firmly on the path of high carbon emissions without a clear end in sight."
