Numerical analysis on lunar heat storage system: Multi-objective optimization, heat storage capacity, and thermal insulation performance

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

“…Nevertheless, since there is no need to carry large quantities of additives from Earth, the melting/sintering of lunar soil has gradually become the major research interests in recent years for the in situ construction of lunar bases on the lunar surface, with relevant research carried out by many research organizations such as the Loughborough University in the United Kingdom and the Harbin Institute of Technology in China. 158,159…”

“…Closed Brayton cycle based power generation system. 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.…”

“…The use of solar energy to sinter and/or melt lunar regolith can be a way to coalesce it into a continuous block with higher thermal conductivity than the natural lunar regolith. 184,185 In accordance with this idea of lunar regolith improvement, many scholars have designed solar thermal storage systems that utilize collectors to absorb solar energy and transfer heat to the tank for use during lunar night. 186…”

“…Similarly, the supply of cold energy to the lunar base is a critical study for the lunar base. There are currently two ways of combining electrical energy generation and cooling system: (1) the use of ejector, 185,189 (2) turbine driven compressor, [190][191][192] which can be found in Figure 6B and C. The first option utilizes an ejector to realize the refrigeration process, i.e., the ejector replaces the expansion valve to recover the pressure energy of the high-pressure fluid.…”
