A fuel delivery and storage system is provided. A further aspect employs a remote central controller and/or software instructions which receive sensor data from stationary and bulk fuel storage tanks, portable distribution tanks, and end use tanks. Another aspect of the present system senses and transmits tank or hydrogen fuel characteristics including temperature, pressure, filled volume, contaminants, refilling cycle life and environmental hazards. Still another aspect includes a group of hydrogen fuel tanks which is pre-assembled with sensor, valve, microprocessor and transmitter components, at least some of which are within an insulator.

The invention relates to a compressed gas storage unit (1) for mobile applications, in particular for storing hydrogen on board a vehicle, comprising at least one metal storage housing (2) which delimits a storage volume (3) that can be filled with compressed gas, as well as at least one temperature- and/or pressure-sensitive overload valve (4) arranged on the storage housing (2). According to the invention, the storage housing (2) or the compresses gas storage unit (1) is surrounded by a heat protection shield (5) at least in regions, preferably releasing the at least one overload valve (4). The invention also relates to a vehicle comprising a compressed gas storage unit (1) according to the invention for storing hydrogen.

An apparatus and method for protecting a gas container interior, where an inlet and exhaust manifold include a port assembly attachable to a port of the gas container is provided, the gas container interior is exposed to sequential self-saturating surface reactions by sequential inlet of reactive gases via the port assembly and the port into the gas container interior, and reaction residue is pumped via the port and the port assembly out from the gas container.

A method and apparatus for applying a cladding layer to a surface of a component uses a cladding tool having a maximum reach less than the size of the surface. Geometry of the surface is segmented into a plurality of tessellated segments, each of which has a peripheral extent determined by a maximum reach of the cladding tool. A nominal tool subpath for each tessellated segment is generated, and then combined to generate a nominal tool path for depositing the cladding layer on the surface. The surface is clad using the nominal toolpath, including a process of adjusting the nominal tool path to an adjusted tool path that accounts for dimensions of the bead to be deposited by the tool to match an edge of the bead to be deposited with an edge of a previously deposited bead.

A system for powering a vehicle is provided. The system can include an engine or power generation system to be powered by a fuel and a housing. The housing can be configured to couple to one or more frame rails of the vehicle, receive and protect a cylinder configured to store the fuel to be used by the engine or power generation system. The housing can have one or more access panels allowing access to an interior of the housing. The cylinder can include a first end portion, a second end portion, a central body forming an enclosed cavity for storing pressurized gas, a reinforcement structure disposed over the central body, and a metal foil interposed between the reinforcement structure and central body. The metal foil can be configured to reduce permeation of contents of the cylinder.

Provided is a composite inner frame multi-bonded barrel, a shell-integrated projectile propellant tank including the same, and a method for manufacturing the barrel and the tank. The shell-integrated projectile propellant tank may include the composite inner frame multi-bonded barrel including a cylinder portion including a plurality of inner frames bonded together; a dome portion including an upper dome frame and a lower dome frame bonded to an upper end and a lower end of the cylinder portion, respectively; a cylindrical shell coated on an outside of the composite inner frame multi-bonded barrel; and at least one manhole cover sealing a manhole cover coupling hole formed in a center of the upper dome frame or the lower door frame, and the at least one manhole cover has a fluid injection port formed on one side thereof.

A method of coating a high-pressure fluid vessel comprises filling a high-pressure fluid vessel with a coating solution, draining the coating solution, and drying a remainder of the coating solution in the high-pressure fluid vessel. The coating solution may include a thermoplastic elastomer that is hard with a low glass transition temperature and a high melting temperature. Drying the remainder of the coating solution may form a food grade coating within the high-pressure fluid vessel.

In one aspect the present disclosure relates to a method of manufacturing a cryogenic pressure vessel. The method may include providing a metal lined, composite wrapped vessel which has a boss. The method may further include securing an inlet to the boss, and then encapsulating the metal lined, composite wrapped vessel within a metallic layer in a vacuum controlled environment to form an encapsulated inner tank subassembly. The method may further include securing at least one support to an exterior of the encapsulated inner tank subassembly, and within the controlled vacuum environment, applying a metal coating over the encapsulated inner tank subassembly and the at least one support to form a metal coated, encapsulated inner tank subassembly. The method may further include, within the controlled vacuum environment, encapsulating the metal coated, encapsulated inner tank subassembly within a metallic vacuum jacket, which forms the cryogenic pressure vessel.

Provided is a high-pressure tank including: a helical layer containing first fibers that are wound in a helical pattern and a first resin that fixes the first fibers; a hoop layer located outward of the helical layer in the high-pressure tank and containing second fibers that are wound in a hoop pattern and a second resin that fixes the second fibers; and an intermediate layer located between the helical layer and the hoop layer and containing third fibers that are thinner than at least either the first fibers or the second fibers and a third resin that fixes the third fibers, the first fibers of the helical layer, and the second fibers of the hoop layer.

A gas enclosure of can include a refractory metal liner adapted to surround and enclose a gas to be contained; a ceramic matrix composite cladding; and a diffusion barrier layer disposed between the refractory metal liner and the ceramic matrix composite cladding.
