 The station would have had an efficiency of 46 % , which in comparison to conventional subcritical coal @-@ fired power stations , equates to a reduction in carbon dioxide ( CO2 ) of 23 % per unit of electricity generated . The station would have utilised pollution abatement and gas cleaning systems , including selective catalytic reduction , to remove nitrogen oxide , and Flue @-@ gas desulphurisation , to remove sulphur dioxide . The station would also have been able to allow the installation of Carbon Capture and Storage ( CCS ) technology , when it becomes technically and commercially viable . There was also a possibility that the station may have co @-@ fired biomass , and <unk> heat as a combined heat and power plant .
