A thermochemical solar energy storage concept involving the reversible reaction CaO + H{sub 2}O yields Ca(OH){sub 2} is proposed as a power system element for a lunar base. The operation and components of such a system are described. The CaO/H{sub 2}O system is capable of generating electric power during both the day and night. The specific energy (energy to mass ratio) of the system was estimated to be 155 W-hr/kg. Mass of the required amount of CaO is neglected since it is obtained from lunar soil. Potential technical problems, such as reactor design and lunar soil processing, are reviewed.
