A device for storing and transporting liquefied gas, including a first inner reservoir extending in a longitudinal direction, a second outer reservoir, the device having a system for holding the first reservoir in the second reservoir having a first rigid connection between the first reservoir) and the second reservoir at a first longitudinal end, and, at a second longitudinal end of the device, a mechanism for suspending the first reservoir inside the second reservoir having an assembly of tie rods, a first end of the tie rods being attached to a sheath that is secured to the first reservoir via a washer(s) and nut assembly, these being fitted around the tie rod, a second end of the tie rods being attached to a sheath that is secured to the second reservoir via a washer(s) and nut assembly.

A double-walled tank comprising at least one connection system connecting the outer and inner enclosures and enabling them to move in relation to one another in at least a longitudinal direction parallel to an axis of displacement when in operation. The connection system has an annular linear connection between a first contact surface rigidly connected to the outer enclosure and a second contact surface rigidly connected the inner enclosure, the first and second contact surfaces arranged opposite one another and configured to be in contact with one another along a contact circle that has a center positioned on the axis of displacement.

cryogenic vessel includes a shell, an inner vessel and a thermal insulation layer arranged on a periphery of the inner vessel, a gap is provided between the shell and the inner vessel to form a sandwich space in a vacuum environment. The pressurizing device includes a fixing member, a protruding member, a heat conducting member, an operating member and a connecting member.

A cryogenic hydrogen storage vessel includes an outer vacuum vessel, a reinforcement ring on the outer vacuum vessel, an inner pressure vessel inside of the outer vacuum vessel, and a vacuum space between the outer vacuum vessel and the inner pressure vessel. One embodiment of the cryogenic hydrogen storage vessel includes an outer vacuum vessel; a hump-shaped reinforcement ring on the outer vacuum vessel, the hump-shaped reinforcement ring including an external hump portion that protrudes from the hump-shaped reinforcement ring and an internal recess in the hump-shaped reinforcement ring; an inner pressure vessel inside of the outer vacuum vessel, a vacuum space between the outer vacuum vessel and the inner pressure vessel, and a composite support ring in the vacuum space extending from the hump-shaped reinforcement ring on the outer vacuum vessel to the inner pressure vessel, the composite support ring nested in the recess in the hump-shaped reinforcement ring.

This invention relates to a containment system for storing liquid hydrogen (3), comprising one or more walls forming a containment space (2). At least one of the one or more walls comprises an inner barrier layer (11), an outer barrier layer (12) and one or more spacer elements (14) disposed between the inner barrier layer (11) and the outer barrier layer (12) to separate the first and second barrier layers (11, 12), thereby creating space for a vacuum layer (13) in between the inner and outer barrier layers (11, 12). The outer barrier layer (12) is made of cryogenic ice having a temperature of below minus 150 C.

A high-pressure gas container (100) includes an inner layer (11) configured such that high-pressure gas is filled inside, a boss part (13-1, 13-2) provided at least at one position of the inner layer and configured to cause the gas to flow in and out, and an outer layer (12) configured to cover an outer periphery of the inner layer to reinforce the inner layer and having a higher gas barrier property than the inner layer. A gas discharge port (15-1, 15-2) is provided between the boss part and the outer layer, and a gas ventilation part (14) is formed between the inner layer and the outer layer such that the gas having permeated through the inner layer is discharged into atmosphere through the gas discharge port.

A tank or tank system for storing a cryogenic liquid exhibiting at least one collecting container with an upper region and a lower region, so as to hold the cryogenic liquid, at least one arrangement for feeding and discharging liquids and at least one arrangement for feeding and discharging gases, wherein the tank further exhibits at least one frame structure comprising a thermal insulation material.

A fluid storage and pressurizing assembly includes a storage receptacle and a pump assembly. The storage receptacle includes an inner vessel defining a cryogen space for storing a fluid at a storage pressure and a cryogenic temperature, an outer vessel surrounding the inner vessel, and an insulated space between the inner vessel and the outer vessel, and a pump assembly. The pump assembly includes a pump having an inlet disposed within the cryogen space for receiving a quantity of the fluid from the cryogen space, and an outlet for delivering the fluid therefrom, and a pump drive unit for driving the pump, the pump drive unit being at least partially disposed within a space defined by the storage receptacle

A multilayer insulation is provided that includes radiant barrier layers separated by one or more spacers. The spacers are configured to maintain separation and provide a low conductivity thermal path between adjacent radiant barrier layers of the multilayer insulation. In certain implementations, the spacers have a shape defined by the intersection of three orthogonally oriented discs and are disposed between two radiant barrier layers of the multilayer insulation. In other implementations, the spacers are mechanically coupled to and extend from a radiant barrier layer.
