Abstract
A solar energy collection and storage system and a method of collecting and storing solar energy. The system includes a device for focusing solar energy onto a reaction chamber for the conversion of metal hydride to liquid metal and hydrogen, a metal/metal hydride chamber containing a metal/metal hydride mixture, a hydrogen storage system using hydrides and a thermo-cline for recovering the thermal energy from the hydrogen when it is cooled from 2000 F to ambient conditions for storage.

29. A thermal storage method wherein energy is stored when a compound of two or more materials are separated into components.
Said components operate reversibly so that when they combine they release thermal energy and when they are separated they absorb thermal energy. Said components store their energy in the heat of formation differences between the individual materials or elements and the compound which is formed when they are brought together.
-
37. A thermal storage system wherein the process of separating two materials provides a means for the storage of thermal energy in chemical form.
Said materials release energy when they are recombined. The direction of said materials to combine or separate is determined by the hydrogen gas pressure at a constant operating temperature.
