About Paper:

In order to ensure efficient operations in future lunar settlements and Earth-based systems, the liquefaction of hydrogen is necessary for its optimized transportation and storage. However, traditional gas compression liquefaction technology suffers from issues such as refrigerant pollution, low efficiency, and high energy consumption. This research focuses on developing a hydrogen liquefaction technique by investigating High entropy alloys, or alloys with a large proportion of many elements, as magnetocaloric materials within an Active Magnetic Regenerative Refrigeration (AMRR) system. The proposed strategy entails a comparative analysis of HEAs to assess their suitability for hydrogen liquefaction by analyzing properties, including heat lift, temperature change, magnetic response, and other relevant characteristics. Subsequently, the selected HEAs will be modeled and integrated into a customized AMRR system iteratively designed and developed for Lunar hydrogen liquefaction. The research aims to provide a detailed comparison of the HEA experimental analysis results, evaluate their effectiveness as magnetocaloric refrigerants, and offer recommendations for a modified Technology Readiness Level (TRL) 4-6 AMRR system tailored for lunar settlements. The primary conclusion drawn from this research is that using HEAs as magnetocaloric materials has the potential to significantly enhance the efficiency of hydrogen liquefaction systems in lunar settlements, thereby validating the exploitation of In-Situ hydrogen.
