Hydrogen storage for transportation applications requires high volumetric and gravimetric storage capacity. B–N compounds are well suited as storage materials due to their light weight and propensity for bearing multiple protic (N–H) and hydridic (B–H) hydrogens. This critical review briefly covers the various methods of hydrogen storage, and then concentrates on chemical hydrogen storage using B–N compounds. The simplest B–N compound, ammonia borane (H₃NBH₃), which has a potential 19.6 wt% hydrogen storage capacity, will be emphasised (127 references).

The use of metal–ligand cooperation (MLC) by transition metal bifunctional catalysts has emerged at the forefront of homogeneous catalysis science.

In situ ¹¹ B NMR monitoring, computational modeling, and external trapping studies show that selectivity and extent of H₂ release in metal-catalysed dehydrogenation of ammonia borane, NH₃BH₃, are determined by coordination of reactive aminoborane, NH₂BH₂, to the metal center.
