The reinforcing layer includes a pair of resin rings each of which is provided encircling a respective end portion of an outer circumferential face of the body, a hoop layer that covers part of the outer circumferential face of the body, between the resin rings, and a helical layer that covers the resin rings, the hoop layer, and the dome portions. The resin rings are configured to cover part of the body from boundary portions between the body and the dome portions, and increase in thickness from the boundary portions toward a middle of the body.

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 pressure vessel system for a vehicle includes a pressure vessel and a fuel line. The system also includes a blocking unit which, in an inoperative state, prevents fuel from passing out of the pressure vessel into the fuel line. A control unit for the blocking unit is designed, under the action of electrical energy, to transfer the blocking unit from the inoperative state into an active state in which fuel can pass out of the pressure vessel into the fuel line. Furthermore, the system includes an electrically conducting connection to an electrical system of the vehicle via which electrical energy can be provided for controlling the blocking unit. In addition, the system includes an access interface unit via which electrical energy for controlling the blocking unit can be provided from an external energy supply if no electrical energy is available from the electrical system of the vehicle.

A storage tank for a cryogenic fluid including an inner tank that is configured to store the fluid and that is seated in an outer envelope, the inner tank and the outer envelope having a shared longitudinal axis, such that a thermal insulation volume surrounds the inner tank, and wherein the outer envelope surrounds the volume about the inner tank. The tank has at least one damping element made of a deformable material positioned between one end of the inner tank and the outer envelope to wedge the inner tank against the outer envelope. This enables a reliable sliding mechanical link to be formed between at least one end of the inner tank and the outer envelope of the tank, thereby increasing resistance to wear and facilitating assembly of the tank.

A hydrogen tank, preferably a tank for storing liquid hydrogen at low pressure in cryogenic condition, includes at least one gaseous hydrogen capture system. The system is provided with absorbent fillers configured to capture the gaseous hydrogen, the absorbent fillers being linked to at least a part of a wall of the tank, and/or to a skin arranged on an outer face of the tank, and/or to an outer jacket intended to implement an auxiliary function. The system has a reduced weight and is able to retain and store gaseous hydrogen which could escape from the tank so as to prevent it from being given off into the environment of the tank. The captured gaseous hydrogen is able to be restored later by the system.

The present invention is at least industrially applicable to recovery of Hydrogen boil off gas during tube trailer refilling with liquid Hydrogen by a sequences of steps that redirects gaseous Hydrogen from the tube trailer to a Hydrogen liquefaction plant.

A mobile hydrogen fueling system for use in fueling mobile hydrogen vehicles includes: a towing vehicle with a hydrogen powered fuel cell that powers the towing vehicle, and a trailer. The trailer includes a hydrogen storage tank, a hydrogen fuel transport device such as a gas compressor or a liquid pump, and a dispenser attached to the hydrogen tank that dispenses hydrogen to a receiving hydrogen tank. A controller regulates the hydrogen fuel transport device and thus the flow of hydrogen that the dispenser dispenses.

A conformable pressure vessel including pressure vessel segments defined by a cavity disposed within a liner. The pressure vessel segments receive and store a gas in a compressed state. Each of the pressure vessel segments includes a first section of the liner having a first diameter and a second section of the liner having a second diameter smaller than the first diameter. The conformable pressure vessel includes a reinforcement layer surrounding the liner, and an inlet in fluid communication with the cavity of the liner. The inlet receives the gas from a gas source. The conformable pressure vessel includes an outlet in fluid communication with the cavity of the liner. The outlet outputs the gas from the pressure vessel segments. The conformable pressure vessel includes a connecting tube in fluid communication with the inlet and the outlet. The connecting tube receives the gas from the outlet.
