Storing Hydrogen With Perhydrides

Hydrogen storage is a critical issue for the hydrogen economy. Current storage technologies are not able to meet the combined gravimetric, volumetric, and system cost targets set by the Department of Energy. To solve the problem, the development of a new material - perhydride ? is proposed. Perhydrides are defined as materials that contain more hydrogen atoms in their molecules than conventional hydrides do based on the valence. This concept is supported by the versatile bonding capability of hydrogen and the recent discoveries in the chemistry of hydrogen clusters.
