A compressed gas storage system that includes a pressure vessel. The pressure vessel includes a first vessel portion and a second vessel portion in fluid communication with the first vessel portion. The pressure vessel includes a third vessel portion in fluid communication with the second vessel portion. The compressed gas storage system includes a first valve positioned between the first vessel portion and the second vessel portion and a second valve positioned between the second vessel portion and the third vessel portion. The first valve allows and impedes fluid flow between the first and the second vessel portions. The second valve allows and impedes fluid flow between the second and the third vessel portions.

A hydrogen filling device capable of suppressing mixing of water when filling a hydrogen tank with hydrogen. A hydrogen supply unit, a trap tank through which hydrogen supplied from the hydrogen supply unit, a main pipe which is a pipe extending from the trap tank, and a hydrogen supply branch pipe which is a pipe extending from the main pipe to the hydrogen tank, the trap tank includes a container portion, an inlet for flowing hydrogen into the container portion from the hydrogen supply unit, provided vertically above the inlet, and an outlet for flowing out the hydrogen from the container portion to the main pipe.

A method of dispensing compressed natural gas (CNG) includes assigning a first priority to the filling of a first destination tank and assigning a second priority to the filling of a second destination tank. The second priority is lower than the first priority. The method also includes filling the first destination tank from a first CNG source while filling the second destination tank from a second CNG source. The second CNG source provides CNG at a lower pressure relative to the pressure at which the first CNG source provides CNG.

A motor vehicle includes at least one pressure vessel for storing fuel, and at least one holder for holding the pressure vessel. When installed, the holder encloses one end of the pressure vessel. The holder has a hard shell and an inner layer, wherein at least regions of the inner layer, when installed, are arranged between the hard shell and the connecting element. The hard shell has a higher rigidity than the inner layer.

A gas pressure tank system is disclosed, and includes at least one gas pressure tank comprising a thermal pressure relief device. The thermal pressure relief device may include a valve unit fluidically connected to the at least one gas pressure tank and including at least one fluid path, by way of which a gas stored in the at least one gas pressure tank can be discharged into an environment. The valve unit may include a locking element which can be moved between an open position, in which the gas can flow through the fluid path, and a closed position, in which no gas can flow through the fluid path. The thermal pressure relief device may include a first trigger means configured to detect heat impact at least at one location of the gas pressure tank system spatially separated from the installation location of the thermal pressure relief device.

A system for hydrogen dispensation can include: a hydrogen collector; a cryo-compressed buffer storage system; and a hydrogen dispenser. The system functions to facilitate hydrogen fueling/dispensation (e.g., rapid dispensation) while additionally utilizing hydrogen storage in a cryo-compressed hydrogen state. The system and/or method may be implemented in any general use case that requires hydrogen storage and/or hydrogen refueling.

A type IV conformable pressure vessel assembly is provided comprising a plurality of elongated folded tanks and an on-tank-valve (OTV) manifold assembly configured to pass fluid into and out of an interior of the plurality of elongated folded tanks through a plurality of first and second filling couplers directly connected to respective first and second ends of the plurality of elongated folded tanks. Each of the plurality of elongated folded tanks have at least two chambers for the storage of fluid. The manifold valve assembly receives fluid from an external source, selectively provides the external fluid to one or more of the plurality of first and second filling couplers.

Hydrogen pressure vessel, comprising a shell with an internal volume; wherein: the pressure vessel is arranged for storing compressed hydrogen at a pressure greater than 200 bar; the shell is made of a steel having a yield strength (S.sub.y) of at least 355 MPa; and said shell is formed by a multitude of longitudinally extending segments, wherein each longitudinally extending segment has a circumferential wall, with a wall thickness (WT), defining an internal diameter (ID.sub.1), the multitude of longitudinally extending segments together forming the internal volume of the shell.

A hydrogen filling device capable of suppressing mixing of water when filling a hydrogen tank with hydrogen. A hydrogen supply unit, a trap tank through which hydrogen supplied from the hydrogen supply unit, a main pipe which is a pipe extending from the trap tank, and a hydrogen supply branch pipe which is a pipe extending from the main pipe to the hydrogen tank, the trap tank includes a container portion, an inlet for flowing hydrogen into the container portion from the hydrogen supply unit, provided vertically above the inlet, and an outlet for flowing out the hydrogen from the container portion to the main pipe.

A prismatic tank for the containment of liquefied gas. The tank is formed of extruded materials and comprises an outer insulation layer.
