The reinforcing layer includes a helical layer group including laminated helical layers, and a large-angle layer provided adjacent to the helical layer group and on the liner-side. The helical layer group includes an innermost layer that is closest to the liner and that is one of first and second helical layers respectively having the largest and second largest fiber winding angles, an outermost layer that is closest to an outer surface of the high-pressure tank and that is the other one of the first and second helical layers, and an intermediate layer disposed between the innermost and outermost layers and including a helical layer that is smaller in winding angle than the innermost and outermost layers.

Implementations of the present disclosure generally relate to an apparatus for large-scale external pressure storage, and more particularly for large-scale storage of liquid hydrogen and other products that require evacuated insulation. In some examples, a plate for a storage apparatus is provided. The plate a body that includes a beveled joint with the body having a nominal thickness at the beveled joint. The beveled joint is configured to be welded to a corresponding beveled joint of an adjacent plate.

A storage tank includes an upper tank having a cylindrical shape and a lower circumferential edge having a contoured shape. A top surface of a tank floor body is in sealing contact with the lower circumferential edge and conforms to the contoured shape. The tank floor body has a saddle shape. An upper cap is joined to an upper circumferential edge of the upper tank. The upper cylindrical tank shell, the tank floor body, and the upper cap form an inner storage volume. The storage tank may also include a lower skirt having a cylindrical shape and an upper circumferential edge having the contoured shape. A bottom surface of the tank body floor is joined to the upper circumferential edge and the lower tank skirt, and the upper tank share a common central axis.

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.

The invention is a reservoir for the storage of a pressurized fluid such as compressed air notably to the storage and recovery of energy using compressed air. In particular, the reservoir comprises at least one tube formed of an arrangement of concentric layers (C1, C2, C3, C4). This arrangement comprises, working from the inside toward the outside of the tube, an internal layer (C1) formed of concrete, a layer (C2) formed of steel of thickness E, at least one layer (C3) formed by a winding of steel wires (C3″) on a sublayer (C3′) of concrete, and an external layer (C4) which protects the wires against at least one of physical and chemical damage, and in which the wires are subjected to circumferential (hoop) tensile prestress with at least one of the thickness E and the prestress being rated to withstand the pressure of pressurized fluid.

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.

In a membrane type heat insulation system for a cryogenic liquefied gas carrier cargo tank and a liquefied gas fuel container, a secondary heat insulation layer comprises a plurality of panels which are stacked in multiple layers while each pair of upper and lower panels is arranged to intersect each other, whereby heat loss which may occur in the gap between the panels can be minimized and deformation due to a temperature difference can be minimized.

A liner configuring member configuring a liner includes a main body section which is configured from a resin material and has both ends opened. That is, both ends of the main body section are, respectively, a first open end and a second open end. There is provided in a vicinity of the first open end a first flange section where a first annular recess is formed by a first bottom section and a first side section. On the other hand, there is provided in a vicinity of the second open end a second flange section where a second annular recess is formed by a second bottom section and a second side section.
