Abstract:
A compressed gas tank (1) made from carbon fibre materials, which has a filling and removal neck, and a method for the production thereof, with the following steps: providing a fusible core, which forms an interior of the compressed gas tank (1), wrapping the core with at least one carbon fibre bandage and impregnating the carbon fibres with a curable polymer matrix material, thereby providing a preform of the compressed gas tank (1), consolidating the polymer matrix material of the preform and obtaining the carbon fibre composite compressed gas tank (1), and liquefying the core material by melting, and removing the liquid core material from the filling and removal neck.
Abstract:
A cryogenic container includes an inner vessel for containing a cryogenic fluid, and an outer vessel for insulating the cryogenic fluid from the environment. The inner vessel includes a superconductive layer formed of a material having superconducting properties at the temperature of the cryogenic fluid. The superconductive layer forms a magnetic field around the cryogenic container, that repels electromagnetic energy, including thermal energy from the environment, keeping the cryogenic fluid at low temperatures. The cryogenic container has a portability and a volume that permits its' use in applications from handheld electronics to vehicles such as alternative fueled vehicles (AFVs). A SMES storage system includes the cryogenic container, and a SMES magnet suspended within the cryogenic fluid. The SMES storage system can also include a recharger and a cryocooler configured to recharge the cryogenic container with the cryogenic fluid.
Abstract:
A method of producing a metal article, for example a pressure vessel, including the steps of forming an inflatable envelope of a super-plastic metallic alloy, heating the envelope to within the temperature range for super-plasticity, and applying a differential pressure between the interior and the exterior of the envelope such that the envelope expands as a balloon.
Abstract:
The invention relates to a ship containment system for storing and/or transporting liquefied hydrogen, which system comprises a spherical cargo tank arrangement within the ship's hull, wherein (a) the cargo tank is supported by a skirt arrangement mounted on the hull of the ship through which the tank is mounted in the ship without direct contact between outer layer of the cargo tank [4] and the hull, with hold spaces [10] between the cargo tank and the hull, and comprising a structural transition joint [8] between the upper part of the skirt and the lower part of the skirt; and which system is further provided with (b) a pump for loading and discharging the liquefied gas located in a pump tower [1]; (c) a tank cover [2]; (d) a cargo tank insulation layer [3] that is applied to the outer layer of the cargo tank [4]; wherein: the inner side of the ship's hull [6] is provided with an insulation layer [11], covered by an internal lining at the side of the hold spaces [10], being any suitable foil at the vertical sides of the inner hull, and at the sides below the cargo tank on the bottom of the ship's hull structure [9] being a membrane showing minimal expansion and/or contraction under the conditions applied; the hold spaces [10] are filled with an inert gas and are provided with means for managing pressure and means for monitoring temperature; the skirt is mounted on the hull structure with a mounting setup that comprises a insulating layer in between the skirt and the inner side of the inner hull [ 6 ]; and the tank cover (2) is provided with an internal insulation layer [12]. Further, the invention relates to a process for managing insulation of said ship containment system and a process for managing leakages of said ship containment system.
Abstract:
The invention relates to a compressed gas tank (1) which consists of carbon fiber materials and which has a filling and withdrawal connection. The invention also relates to a method for producing same, having the following steps: - providing a meltable core that forms an internal shape of the compressed gas tank (1), - wrapping the core with at least one carbon fiber bandage and impregnating the carbon fibers with a curable polymer matrix material, thereby providing a preform of the compressed gas tank (1), - consolidating the polymer matrix material of the preform and obtaining the carbon fiber composite compressed gas tank (1), and - liquefying the core material by means of a melting process and withdrawing the liquid core material out of the filling and removal connection.
Abstract:
A storage system and its manufacturing method, for an adsorbing gas includes a plurality of briquette units situated within a storage tank. Each briquette unit includes an open vessel or liner and compressed gas-absorbing particulate matter, which particulate matter includes activated carbon, zeolite, and other appropriate hydrocarbon gas and/or hydrogen adsorbing materials. Optionally, each unit can include a wrapper for preventing circulation of the particulate matter within the storage tank and the storage system can include a mechanism for supplying or removing heat to at least one of the briquette units. Methane powered vehicles, such as automobiles, buses, trucks, and ships can include the above described storage system with compressed methane-adsorbing particulate matter.
