Moon Energy Storage and Generation: Proof of Concept

Abstract

Multiple studies have been performed assessing the possibility to use lunar regolith, processed in diverse methods, to store heat within it and re-use it at a proper time either for heating purposes or heat-to-electricity conversion. These studies focused on the overall system concept and its general performances assessment. The project MESG Moon Energy Storage and Generation, included not only these tasks, but also the design, construction and testing of a demonstrator with the objectives to showcase the critical aspects of the system, such as: processed regolith simulant heating and cooling processes in a relevant environment; heat transfer from the thermal mass to the heat engine; and heat to electricity conversion.
