Patent ID: 7887781

Claim:
A method of storing and, later, releasing hydrogen comprising: ball-milling precursor (a) and precursor (b) at a temperature below about 25° C. that is within a range sufficient to prevent pre-mature release of hydrogen and sufficient to induce reaction between precursors (a) and (b) to provide a ball-milled material comprising a hydrogen-containing product different from (a) and (b), where precursor (a) is borazane (BH 3 NH 3 ) and precursor (b) is a hydride selected from the group consisting of LiH, LiAlH 4 and mixtures thereof and where, on the basis of 100 mole percent of precursor (a) plus precursor (b), the borazane is present in an amount of 50 mole percent or greater; and, thereafter, upon demand for hydrogen, heating the ball-milled material to a temperature of at least 100° C. to release hydrogen.
