11 October 2006 -- E.ON UK has submitted a scoping statement to statutory consultees over its plans to build two new 800 MW supercritical units at its Kingsnorth coal-fired power station in Kent.
The application is for what could be the UK's first highly efficient supercritical coal-fired units, which E.ON UK said will reduce carbon emissions by almost two million tons a year compared to the existing units if built. The two 800MW units would be built next to the existing station, which has four units, and would be carbon capture ready.
The move is part of the company's commitment to reducing its carbon intensity by 10 percent by 2012, compared with 2005. The new units will operate at an efficiency of 45 percent and above, compared to the existing units' efficiency of around 36 percent. E.ON UK has already reduced its carbon intensity by 20 percent since 1990.
The new station would use direct cooling and would have no cooling towers. It would be built next to the existing four 485 MW coal-fired units, which will cease operation and be demolished once the new units are fully operational and proven.
E.ON UK is also considering making the new units capable of burning biomass with coal, although that would be dependent on the continuation of the current framework for biomass co-firing.
They would also be fitted with a flue-gas desulphurization plant, which removes sulfur dioxide and, with selective catalytic reduction, oxides of nitrogen. They could eventually be fitted with amine scrubbers or other carbon capture technology to remove the CO2 before emission.
The new units would only start generating commercially once the existing units had ceased operation, which must be by the end of 2015 under the strictures of the EU's Large Combustion Plant Directive.
If feasible, the new station's carbon capture and storage equipment would be built on the site of the old units once demolished.
