A heat storage medium includes a halide or sulfate salt of a divalent or trivalent metal which salt has hydrated and dehydrated states with high heat of hydration. The medium is dehydrated by heating it with heat derived from a natural source such as solar or geothermal energy or from industrial waste heat and the evolved water removed from the medium. The heat is recovered by rehydrating the medium by the addition of water. The medium may be a porous mass, a slurry of the salt in a water immiscible liquid or a suspension of the salt in a gas and it may be dehydrated by source heating the slurry and separating the water or by passing a source heated gas or immiscible liquid through the medium and the heat may be released from the medium by injecting water into the slurry or by passing a water carrying gas or immiscible liquid through the permeable mass. The storage and recovery procedure may be continuous or batch with the medium being recycled.

The method of handling thermal energy comprising the steps of heating a heat storage medium including a slurry of an at least partially hydrated heat storage water soluble polyvalent metal salt material having relatively hydrated and dehydrated stages dispersed in a water immiscible liquid unreactive with said salt material with thermal energy derived from a source thereof to extract water from and convert said salt material to a water impoverished state, separating from said slurry the water released from said salt material, thereafter adding water to said water impoverished material to effect at least the partial rehydration thereof with the evolution of heat and applying said evolved heat to a heat consuming process.
