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.

An energy storage assembly for a motor vehicle, including a traction battery for storing electrical energy. A flexible pressure element, which is filled with gas or liquid is disposed on the outside of the traction battery or on the inside of a covering component for the traction battery, the gas or the liquid is contained at atmospheric pressure within the flexible pressure element. A pressure sensor is connected to the flexible pressure element, and by which collision-induced pressure fluctuations in the flexible pressure element can be sensed.

The invention relates to a device for storing compressed gas, for example hydrogen or natural gas, comprising a storage line (1) to which at least one compressed gas container (2) is connected via a valve (3). According to the invention, the storage line (1) has at least one connection port (4) for the gas-tight connection of the at least one compressed gas container (2), and a safety element (5), which has a filter function and a shutoff function, is integrated in the connection port (4). The invention further relates to a vehicle having a device according to the invention for storing compressed gas.

A method for controlling purging of hydrogen from a hydrogen circuit system of a vehicle, the hydrogen circuit system having a hydrogen conduit being arranged in fluid communication with at least one hydrogen tank, the method being implemented by a hydrogen control system comprising at least one processing circuitry, the method comprising deactivating one or more vehicle functions and vehicle systems into a non-ignitable state in response to a control signal indicative of a request for purging the hydrogen circuit system, and performing purging of the hydrogen circuit system when the one or more vehicle functions and vehicle systems are set into the non-ignitable state.

A multifunction valve for a flange of a high pressure hydrogen tank for a fuel cell automotive system having a one-piece ejector body applicable to a head surface of a valve body is provided.

An integrated cryogenic fluid delivery system includes a cryogenic liquid tank having an interior, a wall and a geometry. The interior of the cryogenic liquid tank contains a supply of cryogenic liquid. A fuel pickup line is positioned within the interior of the tank and is in fluid communication with a vaporizer so that the vaporizer receives and vaporizes cryogenic liquid from the tank. The vaporizer is positioned outside of the tank and is secured to the wall. The vaporizer also has a shape that conforms with the geometry of the tank.

A pressurized tank system includes a first tank, a second tank, a manifold, a first conduit connecting the first tank to the manifold, a second conduit connecting the second tank to the manifold, a first pressure actuated valve operably connected to the second conduit, a third conduit connecting the manifold and the first pressure actuated valve, and a fourth conduit connecting the first pressure actuated valve and the second tank. The first pressure actuated valve is configured for operation by fluid pressure in the third conduit. A method includes operably connecting a first pressure actuated valve at a junction between the second conduit, a third conduit connecting to the manifold, and a fourth conduit connecting to the second tank; and automatically opening the first pressure actuated valve with the fluid in the third conduit when the fluid pressure level exceeds a threshold pressure level.

The invention relates to a valve device (100) for a gaseous medium, in particular hydrogen, comprising a valve housing (6) which comprises a closing element (14) that is arranged therein and can be moved in the longitudinal axis (18). The closing element (14) interacts with a seal seat (16) in order to release and close a through-opening (22). The valve housing (6) is equipped with at least one spring element (8) which is supported against the closing element (14) and the valve housing (6). Furthermore, the at least one spring element (8) is made of a bimetal.

A thermally activatable safety valve has at least one microwave transmitter and microwave transmitter component. The microwave transmitter and/or the microwave transmitter component is designed to heat at least one thermally activatable opening element.

A container includes first and second hollow shells respectively including first and second inner surfaces to receive a portion of a pressure vessel (PV). The first hollow shell includes a fiber layer that is and at least partially impregnated with resin, and an energy dissipating material that is substantially concentric with the first inner surface and disposed between the first inner surface and the fiber layer. The second hollow shell includes a fiber layer that is at least partially impregnated with resin, and an energy dissipating material that is substantially concentric with the second inner surface and disposed between the second inner surface and the second fiber layer. The first and second hollow shells are attachable to one another to define a volume for at least partially enclosing the PV.
