Abstract: An onboard hydrogen storage unit for a hydrogen powered vehicle including one or more hydrogen storage vessels at least partially filled with a hydrogen storage material which stores hydrogen in metal hydride form. During operation of the hydrogen powered vehicle heat is provided to the hydrogen storage material within the one or more hydrogen storage vessels to aid in desorption of hydrogen from the hydrogen storage material. During hydrogen refueling, heat of hydride formation is removed from the hydrogen storage material within the one or more hydrogen storage vessels to aid in absorption of hydrogen into the hydrogen storage material. The heat of hydride formation is removed from the one or more hydrogen storage vessels via a heat transfer fluid circulated and/or cooled by a stream of compressed air.

Abstract: A modular metal hydride hydrogen storage unit utilizing compartmentalization to maintain a uniform metal hydride powder density thereby reducing strain on the vessel due to repeated cycling. The modular metal hydride hydrogen storage unit may be constructed using prefabricated pressure containment vessels.

Abstract: A metal hydride hydrogen storage unit utilizing compartmentalization to maintain a uniform metal hydride powder density thereby reducing stress on the vessel due to repeated cycling. An hydrogen storage alloy powder occupies at least 60% of the available interior volume of the hydrogen storage unit. Upon cycling of the hydrogen storage alloy powder between hydriding and dehydriding, the rate of increase in the average equivalent pressure exerted on the sidewall is less than 25 psi over at least 20 cycles, the hydriding portion of each of the cycles including the step of charging said hydrogen storage alloy powder to at least 60% of its maximum storage capacity.
