Abstract

Method of utilizing lithium borohydride for the storage and generation of hydrogen where the lithium borohydride is thermally decomposed to generate hydrogen and the remaining decomposition products (contaning boron in free or combined form and lithium in free or combined form) are hydrogenated from a separate source of hydrogen so as to reconstitute at least partially the composition as a hydrogen reserve. A further embodiment contemplates the utilization of aluminum in the composition which lowers the reconstitution temperature and increases the hydrogen capacity of the hydrogen reserve.
