  • Hydrogen storage system and power system incorporating same
    Patent number: 7030770
    Abstract: There is provided a hydrogen storage system having one or more hydrogen storage containers disposed in a confined area with a vent line extending from the one or more storage containers to a location outside of the confined area. One or more sensors are disposed in the confined area for detecting one or more pre-determined unsafe conditions relating to the storage of hydrogen in the contained area and at least one actuator is provided for actuating an operable valve of the vent line to release the hydrogen from the hydrogen storage container to a location outside the confined area at a pre-determined release rate in response to a signal from the sensor indicating an unsafe condition. A power system incorporating a hydrogen storage system as described above is also provided.
