Thermodynamic analysis of combined heating and power system with In-Situ resource utilization for lunar base

Energy system and resource utilization in space: A state-of-the-art review

“…The closed Brayton cycle (CBC) system has the characteristics of compact structure, smaller size, and higher work weight ratio, which can be applied in the nuclear reactor of the spacecraft, 185 the combustion chamber wall of the hypersonic vehicle and other scenarios. 186 Most of its applications are used in combination with other power generation systems. Its main working fluids are supercritical carbon dioxide (s-CO 2 ) 187 and helium-xenon mixture (He-Xe).…”
