Abstract:
1. A tank for the high pressure storage of a fuel gas wherein the tank is adapted to be refueled under high pressure at a refueling depot, including 1) a fuel gas, the fuel gas comprising a heat absorbent media that circulates within the tank and absorbs the gas heat of compression resulting from the increase in pressure within the tank caused by the refueling of the on board tank, 2) a flow path for the fuel gas directing the gas having absorbed the heat to circulate to a heat exchanger external to the tank whereby the heat absorbed by the gas is exhausted from the tank to an environment external to the tank, and 3) a pump that is interposed between the high pressure gas depot refilling line and the tank, comprising a source of power for the circulation of the fuel gas.
