  • Patent number: 7360368
    Abstract: A system and method for vaporizing a cryogenically stored fuel, particularly hydrogen, liquefied by cooling below the ambient temperature is provided. A system for vaporizing a cryogenically stored fuel uses heat arising in the area of a fuel consumer, and includes: a withdrawing line device for drawing fuel out of a tank device; a vaporizer device for vaporizing the fuel drawn via the withdrawing line, while introducing the vaporization heat; a gas line device for feeding the vaporized fuel to each consumer; a heat transfer system provided in the vicinity of the consumer while serving to absorb heat arising in the vicinity of the consumer, and; a fuel/heat exchanger device, through which a heat transfer fluid flows and which forms a part of the vaporizer device, for providing the vaporization heat via a heat flux drawn out of the heat transfer system.
