An onboard hydrogen storage unit with heat transfer system for a hydrogen powered vehicle. The system includes a hydrogen storage vessel containing a hydrogen storage alloy configured to receive a stream of hydrogen and provide hydrogen for use in powering a vehicle. During refueling a cooling/heating loop is used to remove the heat of hydride formation from the hydrogen storage alloy and during operation of the vehicle the heating/cooling loop is used to supply heat to the hydrogen storage alloy to aid in hydrogen desorption.
