The invention relates to a method for refuelling a vehicle (60) or an autonomous vehicle (60). At least one hydrogen tank (10) accommodating gaseous hydrogen is fitted in the vehicle (60). The method comprises the following method steps: The vehicle (60) drives into a refuelling area (24). A refuelling operation (28; 78, 80, 82) is performed on the vehicle (60). Then, the temperature of the contents of the at least hydrogen tank (10) is checked (30). If a temperature (74) of the tank contents of the at least one hydrogen tank (10) exceeds a temperature limit value (32), the vehicle (60) is transferred to a cooling down area (36). There, the tank temperature (44) is checked a second time following a cooling down phase. The tank pressure is checked (48) if the tank temperature (74) lies below a temperature limit value. If the tank pressure (76) in the at least one hydrogen tank (10) is below a tank pressure limit value, the vehicle (60) is transferred to the refuelling area (24) to continue refuelling; if the tank pressure (76) is in the tank pressure limit range, refuelling is halted (52).

A cryogenic storage tank including a first metallic end piece having a first structured connection area on its outer surface, a second metallic end piece having a second structured connection area on its outer surface, a hollow body extending between the first structured connection area and the second structured area. The hollow body is formed of a fiber reinforced polymer-based composite, a first metallic clamp having a third structured connection area and a second metallic clamp having a fourth structured connection area. The hollow body is arranged between and in intimate contact with the first structured connection area of the first metallic end piece and with the third structured connection area of the first metallic clamp and is arranged between and in intimate contact with the second structured connection area of the second metallic end piece and with the fourth structured connection area of the second metallic clamp.

A composite storage tank may include a wall structure including at least three regions including an inner region, an outer region, and at least one permeation barrier. Another region may be optionally incorporated for venting potential permeation of fluids. The at least one permeation barrier and/or the venting layer may be strategically positioned between the inner region and the outer region to reduce or at least partially prevent fluid permeation of the inner region or the outer region. A vehicle may include such a composite storage tank. Methods of forming a composite fluid storage tank may include forming an inner composite region, applying a permeation barrier to an outer surface of the inner composite region, forming an outer composite region, and curing the inner composite region and the outer composite region with the permeation barrier to form the composite fluid storage tank.

A storage tank includes a tank wall, a pressure regulator, a low-pressure coupling, and a fill coupling. The tank wall of the storage tank is configured to contain a stored fluid at an internal pressure within the tank wall, the tank wall including an outer layer, an inner layer, and a regulator mount. The pressure regulator of the storage tank is connected to the regulator mount and is configured to receive a flow rate of the stored fluid and reduce the stored fluid from the internal pressure to an output pressure. The flow rate of the stored fluid is provided, via the low pressure coupling and at the output pressure to an external system. The fill coupling extends through the tank wall and receives the stored fluid from a fluid source to be stored within the storage tank

A compressed gas storage system that includes a pressure vessel. The pressure vessel includes a first vessel portion and a second vessel portion in fluid communication with the first vessel portion. The pressure vessel includes a third vessel portion in fluid communication with the second vessel portion. The compressed gas storage system includes a first valve positioned between the first vessel portion and the second vessel portion and a second valve positioned between the second vessel portion and the third vessel portion. The first valve allows and impedes fluid flow between the first and the second vessel portions. The second valve allows and impedes fluid flow between the second and the third vessel portions.

A high-pressure vessel includes a liner and a reinforcing layer. The reinforcing layer includes an inner reinforcing layer and an outer reinforcing layer.
