A hydrogen refilling station for filling tanks of fuel cell electric vehicles includes a liquid hydrogen tank that feeds liquid hydrogen to an upstream end of a filling circuit that also includes a heat exchanger. The heat exchanger exchanges heat between the liquid hydrogen and heat transfer fluid flows to thereby cool the heat transfer fluid and vaporize the liquid hydrogen to provide a supply of high pressure hydrogen gas for filling hydrogen-fueled vehicle tanks at a downstream end of the circuit. Because the liquid hydrogen is surrounded by the heat transfer fluid inside the heat exchanger, little if any fogging occurs.

A storage system for storing a cryogenic medium, in particular, for storing hydrogen. The storage system includes storage container for receiving the cryogenic medium, at least one pipe projecting from outside the storage container into the storage container, and a shut-off valve in fluidic communication with the at least one pipe. The at least one pipe is closed at an end thereof facing away from the storage container and is open at another end thereof located in the storage container. The shut-off valve is moveable between an open operating state in which an inner space of the at least one pipe is in fluidic communication with an inner space of the storage container, and a closed operating state in which the inner space of the at least pipe is not in fluidic communication with the inner space of the storage container.

In accordance with one aspect of the present disclosure, a mobile machine includes a LNG fuel tank to provide natural gas to a natural gas engine, a pressure relief valve to relieve pressure to a relief vent line, and a liquid separation device. The liquid separation device includes a canister defining an interior space and having a top end and a bottom end, a LNG inlet configured to receive mixed phase fluid into the canister from the relief vent line, a separator disposed within the interior space and fluidly connected to the LNG inlet, the separator configured to direct condensed liquid to the bottom end and to pass vapor to the interior space, a vapor outlet disposed on the top end of the canister, and a liquid drain disposed on the bottom end of the canister.

A system such as a hydrogen refueling station and a method are provided. The system includes a cryotank for storing a liquefied fuel having liquid and vapor phases, a pump for providing a first stream of the liquefied fuel in the liquid phase from the cryotank, a heat exchanger for converting at least a portion of the first stream to a gaseous fuel, a dispenser for dispensing at least a portion of the gaseous fuel to a receiving fuel tank, a refrigeration unit integrated with the heat exchanger, and a backup power unit. The refrigeration unit and the heat exchanger exchange heat with each other, and the refrigeration unit provides cooling capacity to a facility of environment where cooling is needed. The backup power unit generate electric power by using a second stream of the liquefied fuel in the vapor phase or in the liquid phase or both.

A system and a method for liquefied fuel storage are provided. The system includes a first module including a first outer vessel wall and a cryotank, a second module including a second outer vessel wall and a submerged pump at partially inside the second outer vessel wall, and a third module including a third outer vessel wall. The first, the second, and the third outer vessel walls are connected to provide an enclosure as an outer vessel.

A liquid cryogen stored in a liquid cryogen space of a closed insulated cryogenic storage vessel is subcooled by allowing it to enter into a conduit disposed in the liquid cryogen space where it is expanded by a pressure reducer in the conduit, thereby producing a cooled biphasic mixture of the cryogen in liquid and vaporized forms. The cooled biphasic mixture has a temperature lower than that of the liquid cryogen in the liquid cryogen space. Heat is transferred across the conduit from the liquid cryogen in the liquid cryogen space to the cooled biphasic mixture.

A cryogenic fluid containment system is disclosed. The system can store a fluid such as hydrogen at a cryogenic temperature and pressure. As the fluid naturally warms, boil-off fluid is produced by the fluid and can be directed to a backup power system that is configured to consume the boil-off fluid. The boil-off fluid being extracted from the cryogenic fluid containment system causes additional boil-off fluid to be generated from the fluid and refrigerate the fluid within the cryogenic fluid containment system. Additionally, the boil-off fluid can be monitored over time such that as the boil-off fluid accumulates within the storage tank, a boil-off controller can determine whether the boil-off fluid is to be extracted from the storage tank. The boil-off controller can enable the fluid to be maintained below a pressure threshold within the storage tank.

Device for storing and transferring cryogenic fluid, comprising at least one elementary container comprising a liquefied gas tank, the tank being provided with a first pipe for transferring fluid, which pipe has a first end connected to an upper end of the tank, the tank being provided with a second pipe for transferring fluid, which pipe has a first end connected to a lower end of the tank, the first and the second transfer pipes each comprising an assembly of respective valves, characterized in that the first transfer pipe comprises two arms forming two second ends connected in parallel to the first end of the first transfer pipe, the two second ends of the first transfer pipe each being provided with a respective fluidic connection coupling, and in that the second transfer pipe comprises two arms forming two second ends connected in parallel to the first end of the second transfer pipe, the two second ends of the second transfer pipe each being provided with a respective fluidic connection coupling.

A cryogenic fluid delivery manifold system includes a plurality of cryogenic supply tanks. A liquid flow manifold permits flow of liquid a use device. A vapor pressure manifold is coupled to the supply tanks and to a pusher tank for regulating and/or balancing pressure across the plurality of supply tanks.

A tank for storing liquefied gas, having a shell delimiting a storage volume extending in a main direction which is horizontal in the use configuration of the tank, the tank comprising multiple deflecting walls in the storage volume which extend in an offset manner in the main direction configured to force the fluid to perform at least one back-and-forth movement in the main direction as the fluid passes between the lower end and the upper end of the storage volume, wherein a plurality of these deflecting walls are located in the lower half of the storage volume.
