A pressure vessel made of two thin-walled, closed-end tube sections joined at a central hub that encircles the open ends of the two closed-end tube sections, with a plurality of radial bolts attaching the sections together. The central hub has an O-ring groove in which an O-ring rests, providing a seal between the interior of the pressure vessel and the outside. The inner wall of the central hub may have radially thin and radially thick sections to distribute and minimize weight without sacrificing strength. The assembly may be attached to a mounting surface through a dovetail mount on the central hub.

A non-pyrophoric AB.sub.2-type Laves phase hydrogen storage alloy and hydrogen storage systems using the alloy. The alloy has an A-site to B-site elemental ratio of no more than about 0.5. The alloy has an alloy composition including about (in at %): Zr: 2.0-5.5, Ti: 27-31.3, V: 8.3-9.9, Cr: 20.6-30.5, Mn: 25.4-33.0, Fe: 1.0-5.9, Al: 0.1-0.4, and/or Ni: 0.0-4.0. The hydrogen storage system has one or more hydrogen storage alloy containment vessels with the alloy disposed therein.

A storage tank includes a tank wall, a pressure regulator, a low-pressure coupling, and a fill coupling. The tank wall of the storage tank is configured to contain a stored fluid at an internal pressure within the tank wall, the tank wall including an outer layer, an inner layer, and a regulator mount. The pressure regulator of the storage tank is connected to the regulator mount and is configured to receive a flow rate of the stored fluid and reduce the stored fluid from the internal pressure to an output pressure. The flow rate of the stored fluid is provided, via the low pressure coupling and at the output pressure to an external system. The fill coupling extends through the tank wall and receives the stored fluid from a fluid source to be stored within the storage tank

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 low profile flat bombe for Liquefied Petroleum Gas (LPG) storage and method for manufacturing the same, may include a flat bombe body including an upper plate having a plurality of first piercing holes and a pump installation hole formed therethrough, a lower plate having a plurality of second piercing holes formed therethrough at positions vertically coinciding with the plurality of first piercing holes, and side plates integrally connecting first and second side end portions of the upper and lower plates, end plates mounted at front and rear openings in the flat bombe body, and support pipes, wherein upper end portions of the support pipes are welded to internal circumferential portions of the plurality of first piercing holes and lower end portions thereof are welded to internal circumferential portions of the plurality of second piercing holes to maintain a vertical distance between the upper and lower plates.

A plastic tank liner for the storage of a pressurized fluid includes: two ends; two elongated cylindrical sections, the two cylindrical sections having different diameters; and one connecting section connecting the two cylindrical sections. The connecting section has a concave portion connected to the cylindrical section of smaller diameter, and a convex portion adjacent to the cylindrical section of larger diameter. The convex portion has an isotensoid shape. Two convex domes are located on both ends of the plastic tank liner so that each of the domes is connected to a different cylindrical section.

A tank, in particular for a liquid hydrogen reservoir, provided with at least one dome fixed by way of an outer welded joint and having a central portion provided with at least one free end including a first connecting element and at least one dome provided with an open end including a second connecting element, the dome and the central portion being able to be joined together, the first connecting element and the second connecting element being configured to form, when the central portion and the dome are joined together, a protruding tab extending toward the outside of the tank and able to be welded to a protruding end, such a protruding tab making it possible in particular to join together the tank, this being done entirely from the outside of said tank, and to easily mount and dismount the dome, in particular without accessibility issues.

A tank, in particular for a liquid hydrogen reservoir, provided with internal rails for putting an equipment module in place, includes a central portion provided with a wall, and at least one rail and preferably a plurality of rails, each of the rails being integrated in the wall of the central portion of the tank so as to be accessible from inside the tank, such rails allowing easier integration and fastening of a module comprising equipment inside the tank, so as to simplify the manufacture and assembly of the tank.

A tank container for storing gases, in particular for storing hydrogen in a motor vehicle. The tank container includes a main body which is preferably tubular, and comprises reinforcement elements which are arranged on a wall of the main body and are produced using an additive manufacturing process.

Disclosed are thin-walled metal liners, for composite tank, type III, preferably designed to contain gases or hydrogen under high pressure, intended for land, sea, air and space transport, as well as static storage. This liner consists of a main cylinder of revolution, terminated, at least at one of its ends, by an evolutionary shape, substantially hemispherical, gradually connecting to its pole on a cylindrical part of smaller diameter than the main cylinder, the second end of the main cylinder may be either substantially identical to the first, is called “one-eyed” that is to say that it has an evolutionary shape, substantially in the entire hemisphere, that is to say without cylindrical part of smaller diameter than the main cylinder, at its pole.
