Abstract: Two supercritical CO2 (sCO2) Brayton cycles for waste heat recovery in a solid oxide fuel cell (SOFC)-based plant are assessed and compared from thermodynamic and economic perspectives. One cycle considered is a simple sCO2 cycle with recuperation, while the other is the supercritical recompression CO2 (srCO2) cycle. To provide a fair comparison between the performances of the SOFC-sCO2 integrated plants, the flue gas is considered to exit at the same temperature in both cases, through a heating unit to generate hot air.
