Disclosed are gas cylinder assemblies for containing pressurized gas. The gas cylinder assembly has a polymeric liner and a low-permeability barrier layer. The polymeric liner a first end portion, a second end portion and a central body. The central body comprises an outer surface and an inner surface disposed between the first end and the second end. The gas cylinder assembly comprises a reinforcement structure wound over the central body. The gas cylinder assembly further comprises a metal foil interposed between the reinforcement structure and central body. The metal foil is configured to reduce permeation of contents of the polymeric liner.

A pressure vessel (10) is provided with: a cylinder part (1) that defines a pressure chamber (11); a screwing part (3) that is disposed inside at least one of the two ends of the cylinder part; a lid (2) that has a pressure-receiving surface (2A) facing the pressure chamber and that is disposed at a position closer to the pressure chamber than is the screwing part; and a reinforcing ring (4) that is fitted to the outer circumferential surface of the cylinder part. The reinforcing ring covers, along the axial direction of the cylinder part, a part on an outer circumferential surface (1F) corresponding to a portion or the entirety of the engaging portion (12) between the cylinder part and the screwing part.

Method for filling a tank with pressurized gas to a target pressure from at least one pressurized gas source via a transfer pipe provided with at least one valve, the tank having a predetermined inner length and predetermined inner diameter, the end of the transfer pipe forming an injector with a predetermined injection diameter; said method comprises a step for transferring pressurized gas from the source to the tank at a predetermined flow rate, the method comprising a step of controlling the transfer of gas from the source to the tank to reduce the heat produced in the tank, the step of controlling the transfer of gas comprising at least one of: sizing of the injection diameter, and sizing of the flow rate of the transferred gas; the control step being carried out according to the ratio L/D between the length and the diameter of the tank.

A pressure vessel includes front and rear end plates and a plurality of open-ended vessel structures constructed of fibre-reinforced polymer matrix composite material positioned adjacent to one another so that their longitudinal axes are parallel to a longitudinal direction extending between the front and rear end plates. The vessel also includes an outer reinforcement comprising polymer matrix composite material with continuous fibres extending longitudinally around the pressure vessel to secure the front and rear end plates to the vessel structures. At least one of the vessel structures has a partially curved cross section in a plane perpendicular to its longitudinal axis, such that one or more crevices are formed between the vessel structures, running longitudinally between the front and rear end plates and the front and rear end plates are shaped to allow the outer reinforcement to at least partially fill the one or more crevices between the vessel structures.
