Abstract: With the growing interest in lunar exploration around the world, the construction of lunar base has naturally become a focus for researchers seeking sustainable exploration. The extreme temperature variations on the lunar surface and the 14-day lunar night pose great challenges to the stable output of electricity and heat energy from the lunar base energy system. In addition, the launch cost of constructing lunar base has emerged as an urgent research focus. In-Situ Resource Utilization (ISRU) has the potential to be a feasible and effective way. With the aim of reducing launch mass, this study proposes a combined heating and power system (CHP) with ISRU for lunar base. With specific power and net output being the primary research objectives, the system design and thermal performance analysis are conducted. The results show that the proposed system can achieve a net output of 101.25 kW and a specific power of 13.00 W/kg by optimizing working fluid and parameters to satisfy the heating demand of 15 kW. Compared with the solar photovoltaic cell system of 0.86 W/kg and the nuclear reactor power system of 6.88 W/kg, the proposed system with ISRU can significantly reduce launch costs while ensuring sufficient power and heat output.
