The present invention concerns compositions, apparatus and methods for hydrogen storage. In certain embodiments, the compositions comprise sodium alanate and {n<5>-C5H5}2TiH2. In preferred embodiments, the components of the composition are present in specified molar ratios, for example 0.7 NaH to 1.0 Al to 0.1 Ti. In various embodiments, the hydrocarbon rings coordinating the titanium are removed from the composition, for example by melting at 182°C or higher or by cyclic discharge and recharge of hydrogen at temperatures of 100°C or less. Methods for producing and using the claimed compositions are also provided. In various embodiments, the alanate composition may be stored, shipped and used in a modular container, such as a cassette. Exemplary hydrogen utilizing systems and methods for ordering, distribution and shipping of cassettes are also disclosed herein. |
