Abstract
An exergy-based analysis of Lunar power generation and energy storage systems is conducted. Exergy is used as the metric for analysis because it includes both the first and second law of thermodynamics. Exergy destruction rates are calculated through quasi steady state energy and exergy balances, while exergy efficiencies throughout the Lunar diurnal cycle for systems and key subsystems are also quantified. A MATLAB code is used to generate models of system performance, the results of which are presented. The influence of parameters such as Lunar latitude, size, and power supply curve are discussed. Of the options presented, battery energy storage systems exhibit the highest exergy efficiency, while fuel cell and electrolyzer systems exhibit a lower exergy efficiency but more favorable mass.
