Hydrogen storage media

The catalysis pair of decalin dehydrogenation/naphthalene hydrogenation is usable as a hydrogen storage medium loaded in hydrogen vehicles. Here, the power density obtainable from decalin is the most significant factor for the onboard application.

In summary, it is rather obvious that Mg2CoH5, similar to Mg2FeH6, is not competitive in comparison with a catalyzed MgH2 and have no potential whatsoever as a hydrogen storage medium in mobile or stationary applications.

Already, many years before titanium-doped NaAlH4 was recognized as a possible hydrogen storage medium [152], Dymova et al. [153,154] showed that the two-step dissociation of NaAlH4 into NaH, Al and hydrogen (Eq. (6.14)) is in fact reversible. However, due to the poor kinetics of the uncatalyzed system, the reverse reaction requires unpractically severe reaction conditions (200 00 °C, that is, above the 183 °C melting point of the tetrahydride, and 100-400 bar).
