A mount for a double-walled vessel includes a first support to support the mount against an outer wall of the double-walled vessel, a second support to support the mount against an inner wall of the double-walled vessel, and a flexible member connecting the first support and the second support. The first support and can be arranged at a first end of the flexible member and the second support can be arranged at a second end of the flexible member opposite to the first end. Further described are a vessel including at least one such mount as well as a vehicle including such vessel.

A tank system and method for storing cryogenic liquids includes a support cooling channel to reduce heat leak into the vessel of a fuel tank. The fuel tank may store either liquid natural gas or liquid hydrogen or another cryogenic liquid. A cooling fluid is transferred from a second vessel into the support cooling channel of the fuel tank.

Embodiments of systems and methods for transporting fuel and carbon dioxide (CO.sub.2) in a dual-fluid vessel thereby minimizing transportation between locations are disclosed. In an embodiment, the dual-fluid vessel has an outer shell with two or more inner compartments, positioned within the outer shell, including a first inner compartment for storing CO.sub.2 and a second inner compartment for storing fuel. The dual-fluid vessel may connect or attach to a transportation vehicle to thereby allow transportation of the fuel and CO.sub.2. Insulation may provide temperature regulation for the fuel and CO.sub.2 when positioned in the respective first and second inner compartments. One or more ports having an opening in and through the outer shell and a fluid pathway to one or more of the first inner compartment or the second inner compartment may provide fluid communication through the opening and fluid pathway for loading/offloading the fuel and/or CO.sub.2.

Gas pressure actuated fill termination valves for cryogenic liquid storage tanks and storage tanks containing the same.

A hydrogen tank assembly is provided for use in vehicles, such as aircraft. The hydrogen tank assembly has an inner tank wall, an outer tank wall, and an inert gas source. The inner tank wall defines a hydrogen tank volume that is surrounded by a shroud volume which is defined by the outer tank wall. The hydrogen tank volume is filled with cryogenic hydrogen and has a higher pressure than the shroud volume that is filled with an inert gas, such as helium. The counter-pressure of the inert gas prevents micro-cracks in the inner tank wall and increases the in-service life.

An insulation arrangement for an ocean-going ship comprising a modular arrangement of panels, each panel comprising a first cold layer and an opposing ambient layer and a volume therebetween arranged in use to be evacuated to create a vacuum.

Provided are vacuum-insulated articles that comprise an evacuated space disposed between first and second walls and a reflective material disposed within the evacuated space. Also provided are methods of fabricating such articles.

Composite tank apparatus and methods of making and using same. An array of flat-sided co-dependent cells with relatively thin skins made of metallic or non-metallic materials. Each cell has at least two flat wall panel portions connected by radiused sections arranged such that all of the flat wall panel portions are either in flush contact with each other or in flush contact with flat supporting panels of an enclosing structure or thermal insulating material lining an interior thereof. The cells are sealed with each other around a perimeter of at least one pair of matching lightening through-wall holes provided in adjacent pairs of the wall panel portions of the cells to resist relative movement and prevent leakage of fluid therefrom. The composite tank apparatus may include an enclosing structure, and optionally, one or more layers of thermally insulating material lining the interior surface or the exterior surface of the enclosing structure.

An aircraft with a multi-walled fuel tank and method of manufacturing is presented. The aircraft includes a blended wing body and a fuel tank attached to the blended wing body configured to store liquified gas fuel. The fuel tank includes an inner wall, outer wall, and interstitial volume in between that is filled with insulation. The interstitial volume includes a reflective film layer and a structural insulation layer.

The present invention relates to a cryogenic vessel (300a, 300b) having an inner container (301), an outer container (302), an intermediate space (303) between the inner container (301) and the outer container (302) which can be evacuated, and having at least one fluid distribution container (200), which has an internal volume which extends proceeding from one wall of the inner container (301) into the intermediate space (303), is arranged at least partially within the intermediate space (303) and is fluidically connected to the inner container (301), wherein the internal volume of the fluid distribution container (200) is delimited by a wall which has openings (211, 212, 213) that are designed for the connection of one line (311, 312, 313) each or are each connected with one such line (311, 312, 313). The wall (121, 221) has a convex section (101, 201), wherein a wall thickness of the wall at at least one point is less than 90% of a wall thickness of the inner container (301). The invention also relates to a fluid distribution container (100, 200) and to a method for producing a cryogenic vessel (300a, 300b).
