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.

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 BX, an ammonium halide, having the formula NHX, and hydrogen. The boron trihalide is then reacted with the hydrogen to form diborane, having the formula BH, and hydrogen halide. The ammonium halide is then converted to ammonia, having the formula NH, and hydrogen halide. The diborane is then reacted with the ammonia to form borazane, having the formula BHNH.
