A system for connecting at least one pipe between an LNG tank and a tank connection space thereof is also provided. At least one pipe extends from the LNG tank to the tank connection space and which LNG tank is a single-shell tank having one shell. The at least one pipe is connected between the LNG tank and the tank connection space by at least one bellow connection.

A system and method for the transfer of cryogenic fluid fuel includes a nozzle positionable with respect to fuel tank inlet, e.g., of an unmanned aerial vehicle (UAV), a seal to seal the area where the nozzle and inlet are connected, a collapsible and expandable bellows providing an isolation volume where the fluid is transferred from the nozzle into the inlet; a vacuum is provided in the volume to avoid accumulation of fuel or other species in the volume.

A low temperature fluid dual structure pipe includes: an inner pipe through which a low temperature fluid flows; and an outer pipe externally fitted to the inner pipe with a sealed tubular space therebetween. An inactive gas having a melting point and a boiling point each of which is equal to or higher than a temperature of the low temperature fluid is filled in the tubular space between the inner pipe and the outer pipe. When the low temperature fluid flows through the inner pipe, the inactive gas is liquefied or solidified, and therefore, at least one of a liquefied inactive gas layer and a solidified inactive gas layer is formed on an outer peripheral surface of the inner pipe. As a result, a pseudo vacuum layer that is in a substantially vacuum state is formed in the tubular space.

The invention relates to an installation for storing and transporting a liquefied gas, having a sealed pipe (7) that passes through the tank wall so as to define a fluid passage between the inside and the outside of the tank, a sealed metal sheath (29) that is disposed around the sealed pipe (7) and fitted in the opening (22) in the load-bearing wall, the sealed sheath having a longitudinal portion extending at least as far as the sealing membrane (14), the sealing membrane being joined to the sealed sheath (29) in a sealed manner, wherein the load-bearing structure comprises a coaming (24) that protrudes from an outer surface of the load-bearing wall, the sealed pipe being supported by a top wall (26) of the coaming, the sealed sheath (29) having an outer end that is disposed outside the load-bearing wall and attached to the coaming or to the sealed pipe (7) all around the sealed pipe.

The cooling system is arranged for cooling the hydrogen delivered to the vehicle. The system further comprises a dispenser arranged for supplying the hydrogen to the vessel of the vehicle. A supply pipe is arranged for guiding the hydrogen from the center enclosure to the dispenser. The system further comprises a forward path arranged for guiding a supply pipe cooling media from the hydrogen center enclosure towards the dispenser, and a return path arranged for guiding at least a fraction of the supply pipe cooling media back to the hydrogen center enclosure, where at least one of the forward and return paths are thermally connected with the cooling system.

A mobile liquid and gaseous hydrogen refueling apparatus including: a main storage module for receiving liquid hydrogen to produce first gaseous hydrogen; a liquid pumping and transporting module for receiving the liquid hydrogen, pumping the liquid hydrogen, and producing second gaseous hydrogen; a gas compressing and storing module for receiving at least one of the first gaseous hydrogen and the second gaseous hydrogen and compressing and storing the at least one gaseous hydrogen; and a gas converting and transporting module for receiving the pumped liquid hydrogen and the compressed gaseous hydrogen, performing heat exchange between the pumped liquid hydrogen and the compressed gaseous hydrogen, producing gaseous hydrogen for refueling, and transporting the gaseous hydrogen for refueling to a gaseous hydrogen fuel consumption structure.

Sealed and thermally insulating tank incorporated into a polyhedral bearing structure, a first bearing wall and a second bearing wall forming an edge corner, the tank having a first tank wall, a thermally insulating barrier and a sealed membrane, the tank further has an angle bracket with a first flange and a second flange in such a way that the angle bracket connects in a sealed manner.
