WebOct 1, 2024 · We have successfully developed a dynamic numerical model of the SCO 2 recompression Brayton cycle system with a 400 kW turbine output power in past work [3]. The design parameters of turbomachinery in the system including turbine, main-compressor, and re-compressor can be found in Table S1. Web[1]. Reducing power cycle cost and increasing power cycle efficiency are key to this effort. The recompression Brayton sCO 2 cycle (RCBC) is an attractive option, and the U.S. DOE is currently funding research that contributes to achieving a RCBC with >50% thermal efficiency with a turbine inlet temperature near 720°C [2].
