The present disclosure provides an insulation support that is disposed in a vacuum space between an inner container and an outer container of a liquid hydrogen storage container composed of the inner container and the outer container, and supports the inner container, in which the insulation support has a first end being in contact with the inner container and a second end being in contact with the outer container, and is bent several times into several layers; and an automotive liquid hydrogen storage container including the insulation support.

A tensioned intra-Dewar spider assembly that can support a large system inside the Dewar in a way that adds as little thermal load as possible, doesn't overly stress the coldfinger, maintains alignment, and isolates the components from the vibrations of the cryocooler is disclosed.

In a hydrogen or helium container and method for containing the gas, a double-walled housing is provided, which defines an inter-space between the inner and the outer walls, the inter-space being filled with a fluid at a higher pressure than the pressure of the hydrogen or helium contained within the inner wall.

A storage tank for liquid hydrogen comprises first and second shells each constructed of laminate material, the second shell being disposed outwardly of the first shell with respect to the centre of the storage tank. The first and second shells are mechanically connected by a first plurality of pins each of which passes through at least some layers of the second shell and at least some layers of the first shell. The storage tank may be constructed using a simpler manufacturing process involving less tooling and fewer process steps than is the case for known tanks for storing liquid hydrogen. The storage tank has also has a lower mass and reduced thermal losses compared to tanks of the prior art. The plurality of pins allows for the shells to be thinner, and hence lighter, than similar shells in tanks of the prior art.

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 dual-wall, vacuum-insulated container (30, 40) has an external wall (1), an internal wall (3) and there in-between a vacuum chamber (5), in which there is arranged a heat insulation device (2, 20). At least three temperature sensors (13, 13a, 13b, 14, 15) that are spaced apart from another recurringly register instantaneous temperatures (T.sub.1, T.sub.2, T.sub.2A, T.sub.2B, T.sub.3) of the container (30, 40). At least in some points there is calculated a temperature course using a heat insulation model on the basis of the construction and material characteristics of the container and the heat radiation resulting therefrom, which temperature course contains at least two of the temperatures (T.sub.1, T.sub.2, T.sub.2A, T.sub.2B, T.sub.3) registered. From the temperature course there is calculated a desired temperature value for the position of at least one further of the temperature sensors and compared with the actual temperature value actually registered by this temperature sensor. From the deviation between the desired temperature value and the actual temperature value there is detected a change of the heat insulation quality of the container.

A tank suitable for storing a product at a cryogenic temperature, including a fluid tight interior barrier, a fluid tight exterior barrier, surrounding the first interior barrier, an intermediary volume interposed between the interior and exterior barriers and at least one insulating layer positioned in the intermediary volume and including at least one thermal insulation mat, with very low thermal conductivity. The intermediary volume contains microspheres outside of the thermal insulation mats and has an enhanced level of vacuum. This solution makes it possible to maintain satisfactory performance in terms of thermal insulation even in the event of a loss of vacuum in the intermediary volume.

A cryogenic full containment storage tank for realizing a low-liquid-level material extraction function by using a pump column, comprising an inner tank, an outer tank, a pump column, a submersible pump and a material pre-extraction device; wherein the material pre-extraction device comprises a cofferdam, a Venturi mixer, a backflow pipe, a return control valve, a lead-out pipeline and a liquid level detection system. The cryogenic full containment storage tank can make use of a low-temperature medium flowing back from the pump column to extract the low liquid level material outside the cofferdam into the cofferdam to form a local high liquid level and maintain the normal operation of the submersible pump.

A cryogenic storage system basically includes a first cryogenic storage tank, a second cryogenic storage tank, a fluid transfer line and a cryogenic containment structure. The first cryogenic storage tank has a first predetermined capacity of liquefied gas. The second cryogenic storage tank has a penetration free bottom and a second predetermined capacity of the liquefied gas that is larger than the first predetermined capacity of the first cryogenic storage tank. The fluid transfer line is fluidly connected between the first cryogenic storage tank and the second cryogenic storage tank. The heat exchanger converts liquid exiting the first cryogenic storage tank to a higher pressure gas that is used as a motive force to move liquidized gas out of the second cryogenic storage.

Mobile cryogenic tank for transporting cryogenic fluid, notably liquefied hydrogen or helium, comprising an internal shell intended to contain the cryogenic fluid, an external shell arranged around the internal shell and delimiting a space between the two shells, said space containing a thermal insulator, the first shell having a cylindrical overall shape extending along a central longitudinal axis (A), when the tank is in the configuration for transport and use, the central longitudinal axis (A) being oriented horizontally, the tank comprising a set of temperature sensors measuring the temperature of the fluid in the internal shell, characterized in that the set of temperature sensors is situated on the external face of the internal shell and measure the temperature of said shell, the set of temperature sensors comprising a lower sensor positioned at the lower end of the internal shell situated below the central longitudinal axis (A), the set of temperature sensors further comprising a plurality of intermediate sensors distributed over two lateral faces of the internal shell on each side of the central longitudinal axis (A), the plurality of intermediate sensors being distributed vertically between the lower end of the internal shell situated below the central longitudinal axis (A) and the upper end of the internal shell situated above the central longitudinal axis (A).
