A plurality of anchor structures are installed on the inner wall of the tank through the insulation wall to support the interior wall.
Abstract:
The present invention relates to a tank for pressurised gas composed of multiple cells joined by means of connection plates (P), in which each cell (C) is composed of a tubular body sealed at the two ends by means of two caps (2) and the adjacent cells communicate in pairs through a series of ducts, which comprises one or more radial ducts (5) obtained on the head (2a) of each cap (2), annular ducts (9) that surround the head (2a) of each cap (2) and transversal holes (10) obtained on the connection plates (P) and designed to provide communication between the adjacent pairs of annular ducts (9).
Abstract:
An operating method is provided for a cryo-compressed tank for supplying cryogenic hydrogen to a consumer of a motor vehicle under supercritical pressure at 13 bar or more. In order to compensate for pressure loss resulting from hydrogen removal, the removed hydrogen that has been heated in a heat exchanger is conveyed to a heat exchanger, provided in the cryo-compressed tank, by way of a tank pressure regulating valve and a branch line, which branches off of a supply line leading to the consumer. After flowing through the heat exchanger, it is introduced into the supply line downstream of the branching off of the branch line. Over a period of time that significantly exceeds the cycle times of a conventional frequency valve, either the removed amount of hydrogen is guided without limitation into the heat exchanger, provided in the cryo-compressed tank, the tank pressure regulating valve being completely open, or no return of the heated hydrogen into the heat exchanger occurs at all. Downstream of the branching off of the branch line, the supply line has a pressure regulating unit, which ensures that irrespective of the changes in the pressure in the supply line caused upstream of the pressure regulating unit by switching the tank pressure regulating valve, a sufficient and continuous supply of hydrogen to the consumer at the pressure required is guaranteed.
Abstract:
Disclosed is a liquid container adapted to store liquefied natural gas (LNG). The LNG storage container include a sealing wall directly contacting liquid contained in the tank and a structural wall, which is an exterior wall or inner structure integrated with the exterior wall. The container further includes a plurality of connectors mechanically connecting the sealing wall and the structural wall and an intermediate wall structure positioned between the structural wall and the interior wall. The intermediate wall structure is configured to move relative to at least one of the interior wall and the structural wall.
Abstract:
A flat inner container (3), especially an internal tank for a road vehicle, which is surrounded by an outer container (1) and is used for receiving a cryogenic liquid, particularly a fuel. The inner container (3) comprises a combination of the following features: a longitudinally extending monolithic base (4) with a top wall (5) and a bottom wall (6) which are connected to also longitudinally extending sidewalls (7), and with at least two longitudinally extending, substantially straight webs (9) that connect the bottom wall (6) to the top wall (5) so as to form at least one longitudinally extending chamber (10) which is arranged between the webs, extends along the entire length of the base (4) as well as from the bottom wall (6) to the top wall (5), and has a predetermined width between the webs; and at least two caps (11) which tightly seal the two open ends of the base (4) at the periphery; the top wall and/or the bottom wall is/are provided with an arch relative to a planar reference top wall and/or reference bottom wall, the distance of the arch between the inner contour of the top wall and/or the bottom wall and the planar reference top wall and/or reference bottom wall amounting to less than 30 percent of the width of the chamber in the center between the webs.
Abstract:
A pressure vessel is configured such that a plurality of liners 1 are juxtaposed with one another. Each liner 1 includes a tubular trunk 4, and end plates 5 for closing opposite end openings of the tubular trunk 4. Two adjacent liners 1 are integrally connected together via a connection member 2 provided therebetween. The interiors of the integrally connected two adjacent liners 1 communicate with one another via a communication path 3 formed in the liners 1 and in the connection member 2. The ends of connection-member-forming projections 16 provided respectively on the two adjacent liners 1 are butt-joined together, thereby forming the connection member 2. The two adjacent liners 1 have respective through-holes 17 extending from the inner surfaces of the two adjacent liners to the ends of the connection-member-forming projections 16, and the through-holes 17 of the two adjacent liners 1 establish communication therebetween, thereby forming the communication path 3. This pressure vessel can be installed without generation of dead space, can implement a large capacity, and can be reduced in material cost and weight.
Abstract:
Described herein is a portable storage device that stores a hydrogen fuel source. The storage device includes a bladder that contains the hydrogen fuel source and conforms to the volume of the hydrogen fuel source. A housing provides mechanical protection for the bladder. The storage device also includes a connector that interfaces with a mating connector to permit transfer of the fuel source between the bladder and a device that includes the mating connector. The device may be a portable electronics device such as a laptop computer. Refillable hydrogen fuel source storage devices and systems are also described. Hot swappable fuel storage systems described herein allow a portable hydrogen fuel source storage device to be removed from a fuel processor or electronics device it provides the hydrogen fuel source to, without shutting down the receiving device or without compromising hydrogen fuel source provision.

Abstract:
The present invention relates to a pressurized package and a method for manufacturing and filling a pressurized package. The pressurized package has an outer container (10) and an inner container (20) situated within the outer container (10). In the outer container (10) a chamber (11) for material (12) to be dispensed is arranged and in the inner container (20) a propellant chamber (21) for propellant (20) is arranged, which are separated from each other in a manner that is impermeable to liquid and gas. The outer container (10) is closed by a cover part (15) on which a valve part (16) is arranged for dispensing the material (12) from the chamber (11) outwards. To improve pressurized packages of this type, a pressurized cartridge (30) containing a propellant (22) is arranged in the inner container (20), and the pressurized cartridge is associated with an opening mechanism (31) for at least one-time opening of the pressurized cartridge (30) to the propellant chamber (21) of the inner container (20). The opening mechanism (31) reacts to filling of the chamber (11) with material (12) to be dispensed.
