Game-Changing Supercritical CO2 Cycles Are Closer to Commercialization

Supercritical carbon dioxide (sCO2) cycles—which are inching closer to commercial applications for waste heat recovery, concentrating solar power, nuclear, and fossil energy—offer higher thermal efficiencies and power density than conventional steam Rankine and Air Brayton cycles in use today for power generation. But to realize these potentially game-changing cycles, common challenges associated with turbomachinery must […]
