Abstract
Abstract A hydrogen storage container having at least one valved port is filled to about 75% of capacity with particles of low density material having a hydride forming metal coated on the surface of the particles by vapor or vacuum deposition. The density of the particle is on the order of 5% to 50% of the density of the metal coating thereon. Hydrogen gas is adsorbed into or released from the lattice structure of the hydride forming metal.
