Abstract:
The present invention provides a lightweight high pressure vessels that are made from a liner or a liner housing that is overwrapped with a composite material. Unlike conventional high pressure vessels, the lightweight high pressure vessel of the invention includes a liner that comprises a plurality of liner sections without using welding or crimping. In particular, the lightweight high pressure vessels of the invention include a plurality of elements that are combined to form a liner housing and a composite overwrap that provides structural and mechanical strength to maintain integrity of the high pressure vessel. In one particular embodiment, the high pressure vessel of the invention is a diaphragm accumulator.
Abstract:
An operating gas system for an underwater vehicle, particularly for a submarine or an unmanned underwater vehicle, includes a fuel cell system and an operating gas vessel connected in terms of flow to the fuel cell system. In order to achieve simple and efficient storage of boil-off gasses, a gas-receiving device is also provided and is connected to the operating gas vessel. The gas-receiving device contains a sorbent for receiving boil-off gas from the operating gas vessel. The boil-off gas, which is produced in the operating vessel with an operating gas for the fuel cell system and which cannot be consumed directly in the fuel cell reaction, is therefore collected and stored with the aid of the sorbent in the gas-receiving device. A method for operating an operating gas system and an underwater vehicle are also provided.
Abstract:
A fuel gas storage tank is disclosed that can store fuel gas, such as natural gas or hydrogen, in a solid state. The fuel gas storage tank includes a shell having a tank interior, a fuel gas storage material housed within the tank interior, one or more fuel gas injecting tubes, and one or more fuel gas collecting tubes. Each of the fuel gas injecting tube(s) and the fuel gas collecting tube(s) is permeable to fuel gas and is disposed in the tank interior and surrounded by the fuel gas storage material. And, within the tank interior, the one or more fuel gas injecting tubes and the one or more fuel gas collecting tubes are not directly connected to one another.
Abstract:
A fluid storage tank includes a plurality of tank sub-units disposed in an array. Each tank sub-unit of the plurality of tank sub-units has an aperture defined in at least one wall overlapping with another aperture defined in at least one adjacent tank sub-unit of the plurality of tank sub-units. Each tank sub-unit of the plurality of tank sub-units is in fluid communication with a single outlet port for selectively extracting a stored fluid from the tank. Each of the plurality of tank sub-units is in fluid communication with a single fluid fill port.
Abstract:
Gas containment vessels are provided that are comprised of an inner corrosion resistant shell made of lower strength steel alloy or aluminum alloy or thermoplastic polymer, and an outer concentric shell constructed of high strength, albeit lower corrosion resistant, metal or fiber-reinforced composite. The fiber can comprise filaments derived from basaltic rocks, the filaments having been immersed in a thermosetting or thermoplastic polymer matrix, and comingled with carbon, glass or aramid fibers such that there is load sharing between the basaltic fibers and carbon, glass or aramid fibers.
Abstract:
A vessel for holding a pressurized fluid is disclosed, the vessel having a hollow inner shell formed from a moldable material and forming a cavity therein, an intermediate shell formed over the inner vessel, and an outer shell formed over said intermediate shell, said outer shell having a ceramic layer formed on an outer surface thereof.
Abstract:
A hydrogen storage and supply system comprises a storage vessel containing a liquefied or condensed hydrogen in sufficient contact with a catalyst inside the vessel. The storage vessel comprises an inner tank, an outer jacket, a vacuum insulation between said inner tank and outer jacket, and a catalyst disposed inside the inner tank, wherein the catalyst is capable of converting para-hydrogen to ortho-hydrogen at temperatures between about 20° K to about 80° K. A process of storing and supplying hydrogen using the system is also disclosed.
Abstract:
The invention relates to a method for filling a container with gas, gas being inserted into the container under compression. In order to be able to fill the container with a larger amount of gas than before and to reduce gas pressure peaks during filling, it is proposed according to the invention that electrically conducting stretched material is inserted into the container before it is filled with gas. Furthermore, the invention relates to a gas container (1), in particular a high-pressure gas cylinder, for storing gases under pressures exceeding 50 bar, in particular exceeding 200 bar, which contains electrically conducting stretched material (11). With gas containers (1) according to the invention, a higher filling level is achieved than before with a given pressure. Containers with a small wall thickness can be used without a safety risk because of a reduction of gas pressure peaks in the interior of containers.
Abstract:
Embodiments of the invention relate to a fluid enclosure including a structural filler and an outer enclosure wall conformably coupled to the structural filler. Embodiments of the present invention further relate to a method of manufacturing a fluid enclosure. The method includes conformably coupling an outer enclosure wall to a structural filler.
