A system for hydrogen storage including a hydridable material associated with an amount of inert material of high heat capacity sufficient in amount to prevent, during hydriding, the temperature of the combined hydridable material-inert material from rising beyond that temperature at which the hydride of the hydridable material exhibits a hydrogen pressure equal to the partial pressure of hydrogen fed to the system. The system is insulated to inhibit heat transfer into or out of the system.

Reaction heat storage method for hydride tanks

This invention relates to an improved adiabatic process for separating hydrogen from mixed gas streams using hydridable materials as the absorbing medium. The improvement comprises utilizing a composite comprising a thermal ballast in admixture with the hydride material to absorb the heat of reaction and to aid in desorption. By virtue of the intimate contact of the ballast with the hydridable material rapid cycle times plus good bed utilization are achieved.
