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.

A cryogen storage vessel at an installation is filled with liquid cryogen from a liquid cryogen storage tank that has a pressure lower than that of the vessel. After headspaces of the vessel and tank are placed in fluid communication with another via a gas transfer vessel and are pressure-balanced, a pump in a liquid transfer line connected between the tank and the vessel is operated to transfer amounts of liquid cryogen from the tank to the vessel via the liquid transfer line and pump as amounts of gaseous cryogen are transferred, through displacement by the pumped cryogenic liquid, from the vessel to the tank.

A portable cargo handling equipment includes: a liquid hydrogen pipe which includes a first joint connectable to an end portion of a ship-side liquid pipe extending from the ship-side cryogenic tank and a second joint connectable to an end portion of a land-side liquid pipe extending from the land-side cryogenic tank; an emergency release coupling located at the liquid hydrogen pipe; a shutoff valve located between the emergency release coupling and second joint; and an atmosphere open structure including an atmosphere open passage including one end communicating with a portion of the liquid hydrogen pipe which is located between first joint and shutoff valve, and the other end that is open to an atmosphere, an on-off valve that opens and closes the atmosphere open passage; and a heater that is located at atmosphere open passage and heats the liquid hydrogen or hydrogen gas and guided by the atmosphere open passage.

A device for transferring liquid helium into a usage helium tank of a usage cryostat includes a reservoir cryostat with a vacuum-insulated reservoir helium tank configured to store liquid helium available for filling the usage helium tank, a supply line for liquid helium, and a gaseous helium return line. The supply line proceeds from the vacuum-insulated reservoir helium tank and is connected to the usage helium tank. The gaseous helium return line leads into the vacuum-insulated reservoir helium tank and is connected to the usage helium tank. The device further includes a conveying device configured to convey liquid helium from the vacuum-insulated reservoir helium tank through the supply line into the usage helium tank and further configured to convey gaseous helium from the usage helium tank through the return line into the vacuum-insulated reservoir helium tank.

A cryogenic liquid storage apparatus can include a storage container including an inner container configured to accommodate a cryogenic liquid, and an outer container configured to surround a periphery of the inner container, an extraction pipe having one end connected to the inner container, and the other end exposed to the outside of the outer container, the extraction pipe can be configured to selectively extract the cryogenic liquid to the outside, and a radiation-blocking member can be connected to the extraction pipe, configured to transfer and receive heat to and from the extraction pipe, and provided between the inner container and the outer container, thereby obtaining an advantageous effect of improving efficiency in storing hydrogen.

The invention relates to a cryogenic fluid transfer device comprising a first tank storing a cryogenic fluid, a second cryogenic receiving tank, a fluid transfer circuit connecting the tanks and comprising a first pipe that connects the upper parts of the first and second tanks and has a first valve, a second pipe that connects the lower part of the first tank to the second cryogenic tank and has a pump, the pump and the first valve being configured to place the upper parts of the first and second tanks in fluidic communication, the first pipe comprising a bypass portion equipped with a heater and a set of one or more valves configured to make it possible to modify the temperature of the flow of gas transferred from the second cryogenic tank to the first tank via the first pipe.

A gas storage system capable of maintaining stable pressure in a pressurized storage tank, includes a pressure-stabilized gas storage tank and a pressure-stabilizing medium charging and discharging system connected to the pressure-stabilized gas storage tank. The pressure-stabilized gas storage tank includes a pressure-bearing shell capable of bearing a pressure of a storage gas, an elastic liner arranged in the pressure-bearing shell, and a support device for the elastic liner. A pressure-stabilizing medium may be a liquid medium, and a volume of the storage tank is adjusted by charging through pressurizing with a pump or by automatic discharging. The pressure-stabilizing medium may also be a low-boiling-point phase-changeable medium under an operating pressure, and evaporation-condensation of the pressure-stabilizing medium is automatically adjusted according to a variation in a volume of a stored gas by using a matched evaporation-condensation system.

A cryogenic tank apparatus includes an inner container for holding a cryogenic medium, an outer housing surrounding the inner container, an insulation space disposed between the inner container and the outer housing, and at least one heat exchanger. The at least one heat exchanger includes at least one cold flow line through which flows the cryogenic medium held in the inner container, and at least one hot flow line in thermal contact with the at least one cold flow line and through which flows a temperature control medium in such a manner that a transfer of heat takes place between the temperature control medium and the cryogenic medium. The at least one cold flow line is arranged on an inner side of the outer housing and the at least one hot flow line is arranged on an outer side of the outer housing so that a portion of the outer housing acts as a heat transfer surface of the heat exchanger.
