Abstract
The invention provides a method of reversibly producing a source of hydrogen gas comprising mixing together a plurality of hydrogen-containing starting materials; and then heating the mixed materials at a temperature sufficient to release hydrogen. Upon release of hydrogen, there is formed a residue which comprises at least one material different from the starting materials. There is also synergy whereby it is possible to regenerate at least one of the hydrogen-containing starting materials by exposing hydrogen gas to the aforesaid residue.
Claims30
A method of reversibly producing a source of hydrogen gas comprising:
- mixing together at least two hydrogen-containing starting materials, wherein at least one of said at least two hydrogen-containing starting materials is a complex hydride;
- heating said mixed materials at a temperature sufficient to release hydrogen and to form a residue which comprises at least one material which is different from said starting materials;
- and
- regenerating at least one of said hydrogen-containing starting materials by exposing said residue to hydrogen gas.
A hydrogen storage medium having a hydrogenated state and a dehydrogenated state:
- (a) in said hydrogenated state, said medium comprises an amide and a complex hydride;
- and
- (b) in said dehydrogenated state, said medium comprises a residue which comprises at least one material which is different from said amide or said complex hydride.
A method of producing a source of hydrogen gas comprising:
- liberating hydrogen from a hydrogenated composition comprising at least two different hydrogen-containing starting materials including at least one complex hydride by heating said hydrogenated composition at an elevated temperature sufficient to evolve hydrogen gas therefrom, thereby producing dehydrogenated product which comprises a material which is different from at least one of said starting materials.
