  • Patent number: 7959896
    Abstract: In one aspect, the present invention provides a system for methods of producing and releasing hydrogen from hydrogen storage compositions having a hydrogenated state and a dehydrogenated state. In the hydrogenated state, such a composition comprises a hydride and a hydroxide. In a dehydrogenated state, the composition comprises an oxide. A first reaction is conducted between a portion of the hydride and water to generate heat sufficient to cause a second hydrogen production reaction between a remaining portion of the hydride and the hydroxide.
    Type: Grant

  • Patent number: 7695704
    Abstract: A process for producing borazane from boron-nitrogen and boron-nitrogen-hydrogen containing BNH-waste products. The process includes reacting the BNH-waste products with a hydrogen halide, having the formula HX, wherein X is selected from the group consisting of F, Cl, Br, I, and combinations thereof, to form any of the following: a boron trihalide, having the formula BX3, an ammonium halide, having the formula NH4X, and hydrogen. The boron trihalide is then reacted with the hydrogen to form diborane, having the formula B2H6, and hydrogen halide. The ammonium halide is then converted to ammonia, having the formula NH3, and hydrogen halide. The diborane is then reacted with the ammonia to form borazane, having the formula BH3NH3.

  • Patent number: 7462344
    Abstract: The invention provides a method of reversibly storing hydrogen at industrially practicable temperature and pressure conditions. A stable hydrogen storage hydride is mixed with a destabilizing hydride. The stable hydride is capable of releasing hydrogen at a first energy level. When the stable hydride is in the presence of the destabilizing hydride, the stable hydride releases hydrogen at a second energy level. The second energy level is significantly reduced from the first energy level.
