A system for storing chemical energy comprises first and second vessels, the first containing a liquid solution of an alkali or alkaline earth metal hydroxide, halide, or thiocyanate, or ammonium halide or thiocynate at an initial concentration of between about 30% to abotu 80%, by weight, the second vessel containing liquid, a space about the liquid in each vessel and a conduit communicating between the spaces having a valve for selectively allowing liquid vapor to pass between the spaces, means for heating the solution to a temperature above about 80°F., means for cooling the liquid to a temperature below about 55°F., and heat exchange means for transferring heat from the heated solution and for transferring heat to the cooled liquid. Water is the preferred liquid although ammonia, lower alcohols, and polyols such as glycerol, glycols, polyglycols, glycol ethers, lower aliphatic amines and alkanol amines, and mixtures thereof, may be used.
