NOVELTY - A storage system (14) comprises a container (24) having an outer wall defining an interior (36) which is configured to contain liquid lithium hydride in which a portion of the outer wall contains a thermally insulating layer (34), a temperature control system (26) configured to maintain the interior at a temperature such that the lithium hydride decomposes to produce hydrogen gas at a substantially equilibrium state, and an outlet port (97) configured for removal of hydrogen gas.    USE - A storage system for storing hydrogen and providing controlled release of hydrogen gas used for power generation system and fuel cell system (all claimed) used in vehicle e.g. automobile, train, and aircraft.    ADVANTAGE - Lithium hydride can be utilized at sufficiently high temperatures, interior of a fuel storage container can be maintained at a desired elevated temperature, residual gas can be readily removed from intermediate space, convective heat transfer can be inhibited, and decomposition chamber in vehicle can be safely used.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) power generation system comprising a fuel storage system (14) containing a thermally insulated container (24) defining an interior (36) configured to contain liquid lithium hydride and a temperature control system (26) configured to selectively maintain the interior at a temperature such that the lithium hydride decomposes to produce hydrogen gas, and a combustion engine coupled to the fuel storage system and configured to receive hydrogen gas from the fuel storage system and use the hydrogen gas as fuel to generate power; and    (2) fuel cell system comprising a fuel storage system containing a thermally insulated container defining an interior configured to contain liquid lithium hydride, a temperature control system configured to selectively maintain the interior at a temperature such that the lithium hydride decomposes to produce hydrogen gas, and a fuel cell coupled to the fuel storage system and configured to receive hydrogen gas from the fuel storage system and use the hydrogen gas as fuel to produce electricity.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a storage system usable with a propulsion system.
