The present invention proposes a thermochemical battery cycle, termed a Benzene Battery cycle, for efficiently storing electric and/or thermal energy for later and/or distant use. The methods and apparatus herein proposed utilize reversible endothermic fluid and exothermic fluid thermochemical means for efficiently storing H2 in a liquid state at STP. The present invention is generally based on the technology disclosed in U.S. Pat. Nos. 3,225,538, 3,067,594, and 3,871,179, wherein techniques are described for creating a unique thermochemical cycle, termed the Bland/Ewing Cycle (B/E Cycle) after the co-inventors, involving “molecular expansion” and “molecular compression”. The present invention is also based on US Patent Application #18-0954634 which proposes optimizing endothermic and exothermic “segments” for the creation of either Combined Heat and Power (CHP) or Combined Cycle (CC) applications.
