A thermal energy storage apparatus and method employs a container formed of soda lime glass and having a smooth, defect-free inner wall. The container is filled substantially with a material that can be supercooled to a temperature greater than 5°F., such as ethylene carbonate, benzophenone, phenyl sulfoxide, Di-2-pyridyl ketone, phenyl ether, diphenylmethane, ethylene trithiocarbonate, diphenyl carbonate, diphenylamine, 2-benzoylpyridine, 3-benzoylpyridine, 4-benzoylpyridine, 4-methylbenzophenone, 4-bromobenzophenone, phenyl salicylate, diphenylcyclopropenone, benzyl sulfoxide, 4-methoxy-4PR-methylbenzophenone, N-benzoylpiperidine, 3,3PR,4,4PR,5 pentamethoxybenzophenone, 4,4′-Bis-(dimethylamino)-benzophenone, diphenylboron bromide, benzalphthalide, benzophenone oxime, azobenzene. A nucleating means such as a seed crystal, a cold finger or pointed member is movable into the supercoolable material. A heating element heats the supercoolable material above the melting temperature to store heat. The material is then allowed to cool to a supercooled temperature below the melting temperature, but above the natural, spontaneous nucleating temperature. The liquid in each container is selectively initiated into nucleation to release the heat of fusion. The heat may be transferred directly or through a heat exchange unit within the material.

In the method of storing and charging of thermal energy in an apparatus having fluid exchange means coupled to the apparstus, comprising the improvment in the use of an organic supercoolable material having a significant level of supercooling in the liquid state, said material being an organic material having three dimensional molecular structure including a charge pocket and a mating projection of different electronegativity establishes a strong stable liquid state, and selectively initiating the nucleation of the supercooled liquid and freezing of the supercooled liquid with a rate of nucleation and release of heat in excess of the normal rate of dissipation of the heat.
