Title: High temperature direct contact thermal energy storage using phase change media

Abstract

A high-temperature direct-contact thermal energy storage element for use in a system for storage and retrieval of thermal energy in the range of about 400/sup 0/ to about 3000/sup 0/ F. The thermal energy is directly stored, without heat exchange tubes in composite latent/sensible heat thermal energy storage media utilizing the heat of fusion and high-temperature stability of alkaline metal and alkaline earth carbonates, chlorides, nitrates, nitrites, fluorides, hydroxides and sulfates and metal, metallic alloys and mixtures thereof maintained within a porous support-structure material which itself is capable of storage as sensible heat. The thermal energy storage according to the invention may be effectively utilized for storage of thermal energy derived from solar, industrial waste, process heat, and high-temperature gas reactor energy sources and retrieved for a wide variety of uses such as combustion air preheating, drying, space heating, heating of process gases, power generating heat engines and the like.
