A lot of energy storage solutions do exactly that - use heat as energy. i.e. solar heads rock, sand, salt etc. and then later on that heat is turned back into useful energy - either pumping water around households to heat them, or to drive a steam turbine. The bigger the volume of rock / sand / salt, the more efficient the process is.
