Hydrogen Storage by Molecular Polyhydrides.

Abstract

We set out to discover whether molecular polyhydrides would be effective hydrogen storage agents. This three year period has taught us about some very unexpected new aspects of these complexes. We have shown that far from being a rare binding mode, dihydrogen binding occurs without breaking the H-H bond in a wide variety of polyhydrides. These had previously been assumed to have classical structures with all M-H bonds. Not only does H2 bind, but it also dissociates rapidly and reversibly in certain of these nonclassical hydrides. We now find that this complex selectively transports H2 through an organic solvent. Membrane transport is not only an important problem from the biological point of view but it has interesting commercial implications. It is very likely that the rapid and reversible binding could be employed in hydrogen storage.
