Preliminary assessment of electricity costs for existing pulverized fuel plant retrofitted with an advanced supercritical boiler and turbine and solvent CO2 capture
Preliminary economic analyses for baseload electricity generation with carbon capture and storage (CCS) in a recent UK Department of Trade and Industry (DTI) study are extended to include existing pulverized fuel (PF) plant retrofitted with an advanced supercritical boiler and turbine and with solvent scrubbing. Predicted generation costs are in the region of 3.2–3.5 p/kWh. This appears to be comparable with recent IEA predictions for electricity costs from new IGCC plant. Ways in which CCS plant, and solvent scrubbing plant in particular, can provide the flexibility required to complement a high proportion of renewable generation are also discussed.
