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.
