This disclosure provides systems, methods, and compositions for facilitating hydrogen storage, typically using naturally-occurring nanostructured biomaterials such as diatoms or diatomaceous material in their natural or modified forms to facilitate the hydrogen storage. For example, when the nanostructured biomaterials are in contact with a metal hydride such as a complex or a simple metal hydride, the resulting composition functions a catalytic composition that can reversibly desorb and resorb hydrogen gas in an efficient manner. Examples of modification include, but are not limited to, modification of the nanostructured silica with any number of metals.
