Why not fit CCS on an existing coal power station?
It may be possible to fit CCS to existing coal fired power stations, where their location permits the installation of CCS equipment and a suitable transport route for the CO2 is available. However, a number are due to close and others with a limited operating life may not be able to justify the scale of investment. The lower efficiency of conventional plant not only affects their consumption (and cost) of coal but also the emissions of CO2 and thereby the cost of CCS when compared to a modern supercritical coal fired power station of the type proposed for Hunterston.
