Methods, apparatus, and device, for a cryogenic storage system that stores and/or transports a liquid or gas at a temperature below ambient temperature. The cryogenic storage system has an enclosure and a cavity. The cryogenic storage system has a dewar that is positioned within the cavity of the enclosure. The dewar has a payload area that is configured to hold a liquid below ambient temperature. The dewar is configured to hold a liquid below ambient temperature and passively stabilize in an upright position. The dewar is formed with an inner wall and an outer wall and has an opening that allows access to the payload area.

Methods, apparatus, and device, for a cryogenic storage system that stores and/or transports a liquid or gas at a temperature below ambient temperature. The cryogenic storage system has an enclosure assembly. The cryogenic storage system has a dewar that is positioned within the enclosure assembly. The enclosure assembly may comprise be configured to provide little to no friction between the dewar and the enclosure assembly. The enclosure assembly may be configured for shock absorption and/or vibration damping for the dewar during transferring of the cryogenic storage system.

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.

Hardened reusable shipping containers (e.g., shippers) are disclosed herein. A shipper may have a base enclosure that is configured to receive a payload and maintain a temperature of an environment surrounding the payload. The shipper may have various features such as bosses, compartments, and surface features to facilitate protection of a dewar inside the base enclosure, and retention of a payload during shipment. The shipper may have various features to facilitate ready stacking of shippers and suitability for use in air cargo operations.

A cryogenic dewar may include an inner tank and an outer tank. The cryogenic dewar may further include a plurality of trunnion mounts. A first four of the trunnion mounts may be coupled between a front half of the inner tank and a front half of the outer tank. A second four of the trunnion mounts may be coupled between a rear half of the inner tank and a rear half of the outer tank. The trunnion mount may be further strengthen with a plurality of pie-shaped reinforcing pads welded to each other and to an outer surface of the inner tank.

A cryogenic tank for storing cryogenic fluids is disclosed. The cryogenic tank is typically configured to be mounted on a vehicle for supplying cryogenic fuel to a propulsion system of the vehicle. The cryogenic tank comprises an inner vessel for containing cryogenic fluids and an outer vessel surrounding the inner vessel to define a vacuum insulating volume therebetween. The outer vessel is configured to transmit static and/or dynamic loads, while the inner vessel is partially or completely isolated from such loads.

A dewar includes two coaxial openings of different sizes (e.g., to allow for interfacing with a Stirling cryocooler and a Stirling generator), a polytetrafluoroethylene or glass inner chamber (e.g., to reduce conductive heat transfer, particularly through the dewar neck), and an integrated, annular desiccant ring (e.g., for drying low-pressure, ambient air).
