Schoeppel, R J; Terry, L E

Improved power cycles for improving the production of power and refrigeration and for conserving thermal energy, utilizing as a common basic characteristic, a hydride-dehydride-hydrogen power cycle in which hydrogen is reversibly combined with a hydride forming material at a relatively low temperature and pressure, the hydrided material is then heated at constant volume to chemically compress the hydrogen, and finally the material is dehydrided by further heating the material to release hydrogen gas at relatively high pressure and temperature. The pressurized high temperature hydrogen gas as thus developed is used in various ways for producing power and refrigeration, including functioning as a low temperature heat sink for certain auxiliary or ancillary power cycles, prior to recycling the hydrogen gas for reuse in the described hydride-dehydride-hydrogen cycle.
