Abstract: A method and system delivers a cryogenically stored fuel in a gaseous state into the air intake system of a gaseous fuelled internal combustion engine. The method involves measuring the pressure in the vapor space of the cryogenic storage vessel, comparing the measured pressure to a required fuel supply pressure and supplying fuel in gaseous state directly from the vapor space of the cryogenic storage vessel to the fuel delivery line that supplies fuel to the engine, when the pressure measured in the vapor space of the cryogenic storage vessel is equal to or higher than the required fuel supply pressure. The method further involves activating a cryogenic pump to deliver fuel to the internal combustion engine from the liquid space of the cryogenic storage vessel when the measured pressure in the vapor space is lower than the required fuel supply pressure.

Abstract: One aspect of the disclosure provides a system for storing a cryogenic mixture of liquid air and providing a source of breathable air. In an embodiment, the system comprises an insulated storage vessel, a cryocooler, and a vaporizing unit. The insulated storage vessel contains a cryogenic mixture of liquid air comprising liquid nitrogen (LN2) and liquid oxygen (LO2) The cryocooler is mounted to an exterior of the storage vessel to condense liquid air that vaporizes within the storage vessel, thereby returning the vaporized liquid air to a liquid phase such that concentrations of the LN2 and LO2 in the cryogenic mixture remain approximately constant. The vaporizing unit is external of the storage vessel and is in fluid communication with an interior of the storage vessel. Liquid air from the interior of the storage vessel passes through, vaporizes, and exits the vaporizing unit as the breathable air.

Abstract: In a closed circuit a heat transfer fluid is cycled from a first heat transfer zone to a second heat transfer zone via a downcomer, all arranged in an ambient. The first heat transfer zone, housed inside a first box, comprises a first heat transfer surface across which the liquefied stream is brought in a first indirect heat exchanging contact with the heat transfer fluid. The heat transfer fluid is allowed to condense, and a part of the condensed portion of the heat transfer fluid is allowed to accumulate within the first box thereby forming a liquid layer of the heat transfer fluid. Liquid is drawn from the liquid layer and passed through the downcomer to the second heat transfer zone. The second heat transfer zone comprises a second heat transfer surface across which the heat transfer fluid is brought in a second indirect heat exchanging contact with the ambient.
