  • Reaction heat storage method for hydride tanks
    Patent number: 4566281
    Abstract: A system for hydrogen storage including a hydridable material associated with an amount of inert material of high heat capacity sufficient in amount to prevent, during hydriding, the temperature of the combined hydridable material-inert material from rising beyond that temperature at which the hydride of the hydridable material exhibits a hydrogen pressure equal to the partial pressure of hydrogen fed to the system. The system is insulated to inhibit heat transfer into or out of the system.

  • Hydrogen from ammonia
    Patent number: 4544527
    Abstract: A reactor system for production of hydrogen by use of a hydride bed acting upon dissociated ammonia is formed of coaxial annular shells. A central one of the shells includes a hydride bed composed of pelletized material supported on a screen. Inner and outer shells contiguous to the central shell conduct fluid for heat exchange with the hydride bed. Inner and outer diameter of the central shell differ in length by an amount inversely proportional to the square root of the heat adsorption characteristic of the hydride.

  • Fuel injection system
    Patent number: 4520763
    Abstract: Discloses a fuel injection system for the timed introduction of a gaseous fuel such as hydrogen gas into a combustion volume of an internal combustion engine. The system comprises (a) a chamber of fixed volume into which, at one time, gas flows from a fuel source and out of which, at another time, gas flows to a combustion volume of an internal combustion engine and (b) means for varying the pressure of the gas flowing to the chamber.

  • Hydrogen compressor
    Patent number: 4505120
    Abstract: A hydrogen compressor (10) having a hydride (26) suspended in a matrix (28). A cooling jacket (12) circumscribes the compressor (10) and a heater (22) is inserted within the compressor (10). A spring filter (30) is inserted within the compressor (10). A plurality of compressors (10A and 10B) are ganged together and are sequentially energized and deenergized by a plurality of timing means (72, 74A and 74B).
