[0063] The properties of the materials of the present invention evidence their suitability for uses including, but not limited to, hydrogen storage, fuel generation, and fuel in advance of calendar year 2010 and calendar year 2015 objectives and milestone established by the Department of Energy. For example, materials of the present invention demonstrate a high storage capacity for hydrogen in the range up to and including about 24% by weight. Greater yields may be likely with various material combinations. In addition, results show hydrogen can be supplied at a significantly faster release rates and lower release and operating temperatures by simple heating of the dried solid state materials. Further, materials of the present invention exhibit controlled reactivity whereby the quantity of contaminating reaction products is minimized. Other advantages include low foaming observed during the degassing process, which factors into the size, configuration, and/or volume of the containment vessels which ultimately will house the eventual fuels for both onboard and offboard applications. Further, the materials exhibit excellent air and water stability. And, to date, all the reactions involved show a good rationale for reversibility, especially if combined using direct dehydrocoupling. These results suggest the present invention materials can be used or tailored for use in next generation fuel sources applicable to combustion engines, including automobile engines in advance of the 2010 and 2015 objectives for providing hydrogen fuels.
