SCO2 Power Cycles - Department of Energy
Power cycles based on super-critical carbon dioxide (sCO 2) as the working fluid have the potential to yield higher thermal efficiencies at lower capital cost than state-of-the-art steam-based power cycles. Collectively, the unique features of sCO 2 (see matrix below) are creating broad interest in sCO 2 power cycles.
