A method for producing a high-pressure tank capable of suppressing break of a surface resin layer due to gas pressure as well as degradation in the tank quality. The method includes winding a thermosetting resin-impregnated fiber bundle around a liner so as to form an uncured fiber-reinforced resin layer thereon, first heating in which the uncured fiber-reinforced resin layer is locally heated at a first temperature so as to leach the thermosetting resin out of the uncured fiber-reinforced resin layer to form the surface resin layer, and the surface resin layer is cured to have cracks generated therein, and second heating in which the tank is entirely heated at a second temperature lower than the first temperature, so that the fiber-reinforced resin layer and surface resin layer are entirely cured, so as to obtain the tank with the surface resin layer locally having cracks generated therein.

A pressure vessel and a system of a vehicle with such a pressure vessel, wherein the pressure vessel is suitable for storage of pressurized fluids, comprising a housing which extends along a longitudinal axis. The housing defines an inner volume. The shape of the housing, in longitudinal cross-section, is defined by the circumference of a set of circles. The set of circles comprises a central circle, with a center point which is defined by the longitudinal axis, and four primary peripheral circles each of which intersects with the central circle at two points. The primary peripheral circles are axially distributed on the central circle in opposing pairs.

A prismatic tank for the containment of liquefied gas. The tank is formed of extruded materials and comprises an outer insulation layer.

A pressure vessel and a method of manufacturing the pressure vessel is provided that reduces leaks in type IV pressure vessels having a liner with a corrugated section. The method includes providing a liner having a tubular portion having a corrugated section with circumferential corrugations providing alternating ridges and grooves arranged from one end to an opposing end of the corrugated section, applying a barrier to an outer surface of the corrugated section from one end to an opposing end of the corrugated section such that air voids are formed in annular cavities between the liner and the barrier; and applying resin to an outer surface of the barrier. The barrier prevents intrusion of the resin between the barrier and the liner in the corrugated section.

The present disclosure provides a storage system comprising a storage tank configured to store fuel at a cryogenic temperature for a predetermined amount of time. The storage tank may have a plurality of layers comprising: a first layer comprising a pressure vessel for containing the fuel at a pressurized state; a second layer comprising insulation for the first layer; a third layer comprising a vapor barrier; and a fourth layer comprising a shell configured to maintain a rigidity of the storage tank.

A high pressure tank has a liner and a reinforcing layer. The reinforcing layer is formed on an outer surface of the liner. An adhesion inhibiting process that inhibits the liner from adhering to the reinforcing layer is applied to at least a portion of the liner in a region contacting the reinforcing layer.

An organic composite gas storage tank 100 comprises a hollow central portion 106 which is substantially cylindrical and formed integrally with first and second end portions 102, 104, and which defines a longitudinal tank axis 301. The first end portion comprises a hollow truncated conical region which meets the hollow central portion at a first end thereof, the outer and inner radii of the hollow truncated conical region decreasing in a direction along the longitudinal tank axis away from the hollow central portion. An organic fibre winding 107 extends at least between axial positions which coincide with the hollow truncated conical region of the first end portion and the hollow central portion respectively. The first end portion has a higher axial strength than that achievable for hemispherical end portion of a tank of the prior art.

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.

There is provided a high-pressure tank manufacturing method that ensures a shorten heating period compared with a conventional one and eliminates a need for taking out a material for heating after heating. A high-pressure tank manufacturing method includes: disposing a conductive heating material on an outer periphery of a resin liner; winding a conductive fiber with which thermosetting resin is impregnated around the outer periphery of the resin liner on which the heating material is disposed; and heating the heating material and the fiber on the outer periphery of the resin liner by induction heating to harden the thermosetting resin.

The present disclosure provides systems and methods for storing, transporting, and using hydrogen. In some embodiments, the method may comprise (a) storing hydrogen fuel in one or more fuel storage modules; (b) transporting the one or more fuel storage modules to a vehicle fueling site, wherein one or more hydrogen fuel compatible vehicles are located at or near the vehicle fueling site; (c) loading the one or more fuel storage modules into the one or more hydrogen fuel compatible vehicles, wherein the one or more fuel storage modules are configured to be releasably coupled to the one or more hydrogen fuel compatible vehicles; and (d) decoupling the one or more fuel storage modules from the one or more hydrogen fuel compatible vehicles after the one or more fuel storage modules are depleted or partially depleted.
