  • Patent number: 9989017
    Abstract: A method of operating a cryogenic fuel system for supplying fuel to an engine is provided herein. A cryogenic fuel pump is operated to pump fuel to be supplied to the engine. At least a portion of the pumped fuel is diverted to be supplied to an accumulator, when a fuel demand of the engine is less than a discharge output of the cryogenic fuel pump. Further, the supply of the pumped fuel from the cryogenic fuel pump to the engine and the accumulator is stopped, when a pressure within the accumulator reaches a first predefined pressure limit. Furthermore, the fuel is supplied to the engine from the accumulator, when supply of the pumped fuel from the cryogenic fuel pump to the engine and the accumulator is stopped.

  • Publication number: 20180003431
    Abstract: A condensation system for a reservoir, which stores fuel cryogenically, is disclosed. A portion of the fuel exists as a boil-off gas with a first vapor quality. The condensation system includes an absorption unit coupled to the reservoir and is configured to receive and mix the boil-off gas with a refrigerant, forming a liquid solution. A distillation unit is coupled to the absorption unit to receive the liquid solution at a supplemented pressure, and is configured to separate the fuel to a gaseous state from the liquid solution. Further, a cooling circuit is configured to receive the fuel in the gaseous state from the distillation unit at the supplemented pressure and a supplemented temperature, and deliver the fuel to the reservoir at a lower pressure and a temperature, with a vapor quality lower than the first vapor quality.
