Exergy and economic analyses of advanced IGCC-CCS and IGFC-CCS power plants

► Exergy and economic analyses of two advanced fossil fuel power plants configurations. ► Adv. IGCC-CCS case includes H2 and O2 separation membranes and CO2 capture. ► Adv. IGFC-CCS case includes catalytic gasifier, pressurized SOFC and CO2 capture. ► Compared values of IRR and LCOE with conventional power plant configurations. ► Varied price of NG and CO2 emissions to determine configuration with lowest LCOE.
