A high-pressure hydrogen container is provided that has a simple configuration, requiring less labor for manufacture, achieving reduced manufacturing costs, and ensuring pressure resistance. The high-pressure hydrogen container includes a metal cylinder configured to store high-pressure hydrogen, a pair of lid parts configured to cover both end portions of the metal cylinder, and a plurality of fastening parts configured to fix the pair of lid parts in a state where the metal cylinder is clamped between the pair of lid parts.

For improving storage of hydrogen in a vehicle, a hydrogen tank assembly is provided for a vehicle. The hydrogen tank assembly includes an inner tank wall defining a hydrogen tank volume configured for storing liquid hydrogen; and an outer hydrogen collector defining, together with the inner tank wall, at least one cavity outside of the hydrogen tank volume and including at least one hydrogen outlet for leading gaseous hydrogen which leaks from the hydrogen tank through the inner tank wall into the at least one cavity to a hydrogen storage or a hydrogen consumer.

Disclosed are a pressure vessel boss and a pressure vessel having same, the boss comprising: a boss body in which a through hole configured to connect an interior to an exterior of the pressure vessel is formed; and a boss joint portion which surrounds an outer surface of the boss body, radially extends outward, and has an outer surface coming into surface contact with and joined to an opening surface of a liner, wherein the outer surface has a cross-sectional shape having three or more line segments connecting a top to a bottom of the boss joint portion and including at least one convex corner and at least one concave corner.

An Automatic Service Station Facility (ASSF) for replenishing various motivational energy sources onboard different types of AUV, Drones, and Remotely Controlled (RC) or robotic vehicles is disclosed herein. In one embodiment, the automatic service station facility includes a rack, replaceable fuel tanks, a service module, and an electronic computer control system. The replaceable fuel tanks are stocked on the rack and substantially filled with various fluids which are utile as motivational energy sources within fuel-operated vehicles. The service module is mounted on the rack, and the electronic computer control system is connected in electrical communication with the service module. In this configuration, the service module is controllably operable to receive a depleted replaceable fuel tank from a fuel-operated vehicle and also selectively deliver one of the filled replaceable fuel tanks onboard the vehicle. In another embodiment, the service station facility may also stock replaceable batteries for selective delivery onboard battery-operated vehicles. In another embodiment, the ASSF is self-propelled, remotely controlled, and solar powered, being able to move long distances to remote locations which may be hazardous to humans, such as disaster zones or battle fields, where the ASSF can service AUV, Drones, and Remotely Controlled (RC) or robotic vehicles needed for the particular applications. Alternatively, the solar powered ASSF can be made to move continuously and service vehicles continuously for long duration operations like herding cattle for example.

A storage system for storing a cryogenic medium. The storage system includes a storage container operable to receive the cryogenic medium; a first removal line forming a fluid-conducting connection from an interior of the storage container to a first consumer connection for connecting a consumer device that uses the cryogenic medium; a first controllable line shut-off valve arranged in the first removal line; a first heat exchanger arranged in the first removal line; a second removal line, redundant to the first removal line, forming a second fluid-conducting connection from the interior of the storage container to a second consumer connection for connecting the consumer device; a second controllable line shut-off valve, redundant to the first controllable line shut-off valve, arranged in the second removal line; and a second heat exchanger, redundant to the first heat exchanger, arranged in the second removal line.

A high pressure tank includes: a supplying/discharging hole; and a cap having formed therein a cap-side path which is a part of a flow path. A repelling coating interposes between a liner-side end surface facing a resin-made liner, of a flange section configuring the cap, or a flange section-facing outer surface facing the flange section, of the liner. The repelling coating is formed of a material that repels a matrix resin of a fiber-reinforced resin configuring a reinforced layer.
