We claim: 1. A composition, comprising: a support comprising a high surface area material having a surface area of at least about 50 m2/g combined with at least one ammonia borane compound capable of storing and releasing hydrogen connected thereto, wherein said composition releases hydrogen at a greater rate and a lower temperature as compared to said at least one ammonia borane compound in a neat form not combined with said support. 2. The composition of claim 1, wherein said at least one ammonia borane compound is applied to said high surface area material through a method selected from the group consisting of impregnating, depositing, coating, mixing, layering, wetting, physisorbing, chemisorbing, chemically binding, polymerizing, and combinations thereof. 3. The composition of claim 1, wherein said high surface area material is selected from the group consisting of porous materials, non-porous materials, and combinations thereof. 4. The composition of claim 3, wherein said porous material is selected from the group consisting of interconnected porous materials, non-interconnected porous materials, channeled porous materials, porous silica, mesoporous silica, porous titanium dioxide, mesoporous titanium dioxide, porous carbon, mesoporous carbon, porous zeolites, porous aerogels, porous polymers, and combinations thereof. 5. The composition of claim 1, further comprising at least one compound comprising a member selected from the group consisting of Li, Be, B, C, N, 0, F, Na, Mg, Al, Si, and P. 6. The composition of claim 1, further comprising a catalyst. 7. The composition of claim 1, wherein hydrogen release takes place at a temperature below about 95�� C. 8. The composition of claim 1, wherein hydrogen release takes place at a temperature below about 85�� C. 9. The composition of claim 1, wherein said support comprises nanoparticles of a size in the range from about 1 nm to about 10 um. 10. The composition of claim 9, wherein said nanoparticles are coated.
