Two pieces of news provide evidence of a fightback by coal. American Electric Power’s Mountaineer plant in West Virginia is reporting significant success for its small scale carbon capture project. And the UK has just licensed exploratory boreholes for offshore Underground Coal Gasification (UCG), a woefully under-researched technology that may make CO2 sequestration easier. The scale of the challenge facing the globe’s coal users is enormous but with determined research and development, the fuel may remain usable for power generation in a low-carbon world.

The government wants to emphasise the affordability of climate change mitigation. It produces low estimates of the cost of low-carbon technologies. In the recent 2009 budget documents, the government estimated a cost of 1% of GDP to meet the tough new 2020 targets. In his pronouncement on carbon capture at coal-fired power stations, energy and climate change secretary Ed Miliband later said that his proposals will add 2% to electricity bills.
Are these numbers reasonable? Professor Sir David King, the former chief scientific adviser, says no. In a BBC interview of 26 April, he indicates that he thinks that the cost of reducing the UK’s emissions is much higher than the government indicates but also that the financial implications of not dealing with the climate change threat are far higher than even Nick Stern suggests.

The budget confirmed the acceptance of the Committee on Climate Change‘s recommendation for carbon emissions in 2020. The UK will have to reduce its CO2 output by about 110m tonnes by 2020, equivalent to a 21% reduction on actual emissions in 2005 (and 34% on the 1990 figure). The proposed rate of emissions reduction is far faster than the UK has achieved thus far and the chancellor’s budget shows the government has started to recognise the scale of the challenge.

E.ON’s £1bn plan for a new coal-fired power station at Kingsnorth is waiting for approval from the UK government. Other generators have shifted away from coal. Drax, which owns by far the largest coal power station in the UK, is investing in biomass. Other companies have focused on new gas plants. Why is the world’s largest investor-owned utility pushing ahead with a project to burn coal without carbon capture?
The answer, unsurprisingly, is that burning coal to generate electricity is extremely profitable. Very low prices for emissions permits and tumbling coal costs mean that a profit-seeking management team is highly incentivised to try to push for permission to use coal in power stations. This article provides the background calculations for an estimate that the new Kingsnorth will generate an operating profit of about £300m a year if current fuel and carbon prices persist. Additionally, it also tries to show that the cost of fitting CCS equipment and running the plant to capture the large majority of all carbon emissions is likely to add no more than about 1.5p per kilowatt hour to the cost of generating electricity at current coal and carbon prices. This means that a new coal fired power station with CCS may have operating costs only marginally above gas power plants
Nevertheless, E.ON has just asked for government subsidy to install CCS at Kingsnorth from day one. The purpose of this article is to offer an estimate of the maximum the government ought to offer E.ON in order to get it to invest in CCS prior to opening the new power station.

In today’s Independent newspaper (London, Monday 23 February) I argue that we may need to accept some new nuclear power stations. I put forward the view that the trench warfare between the pro-nuclear groups and those that support renewables means that progress towards ‘decarbonising’ electricity generation in the UK is too slow. We probably need to invest in many different types of non fossil-fuel generation as rapidly as we can if we are to meet the tough targets for UK emissions reduction so painfully won by groups such as Friends of the Earth. We no longer have the luxury of ruling out nuclear expansion.
