This request for information (RFI) seeks feedback on technologies to integrate and demonstrate advanced supercritical carbon dioxide (sCO₂) Brayton power cycles that are indirectly heated via thermal energy storage at a turbine inlet temperature (TIT) range between 550 and 630°C. This request is focused on accelerating the commercialization of sCO₂ power cycles that are appropriate for near-term integration with concentrating solar-thermal power (CSP), at temperatures that do not require significant de-risking of the cost and performance of novel materials.
