Abstract:
To protect a tank containing liquefied gas such as LPG, a method of filling the tank (1) with a first portion containing the liquefied gas (5) and keeping free the remaining portion having second volume value as a gas cushion (7). An additional filling (12) is provided which at an increase of the pressure above the normal filling pressure is compressible or comprises compressible parts such that at prevailing overpressures a volume difference equal to the second volume value can be absorbed by the additional filling. The filling can have the shape of a coherent porous coating layer on the inner wall of the tank.
Abstract:
The vessel of a heat storage and release apparatus is provided with a shell made of metallic material with an internal cavity for containing a heat storage and release device and for guiding gas-flow, a first opening through the shell for a flow of gas at high temperature and high pressure in and out of the cavity, a second opening through the shell for a flow of gas at low temperature and high pressure in and out of the cavity, and a lining of thermally insulating material covering only partially the internal surface of the cavity; the lining is located at least in the region where the first opening is located, i.e., where the temperature is higher; in this way, the temperature of the shell can be controlled. Such heat storage and release apparatus can be provided in an energy production plant as a component of an energy storage and release system to be used for compensating differences between energy produced and energy demanded.
Abstract:
Safe storage of volatile compounds or elements is provided by utilizing storage configurations that take advantage of the diffusibility and release characteristics of cell-based materials, such as foam materials. Such configurations may provide storage of hazardous, liquefied gases in closed-cell foam material. Release of gas/liquid from the foam is restricted by the need for the gas to diffuse through the closed cells. Because rapid release is prevented, storage safety is greatly improved.
Abstract:
The invention relates to a method for filling a container with gas, the gas being introduced into the container under compression. The aim of the invention is to fill the container with a greater quantity of gas than in prior art while reducing gas pressure peaks during filling. Said aim is achieved by inserting electrically conducting stretching material into the container before filling the same with gas. The invention further relates to a gas container (1), particularly a high-pressure gas bottle, which is used for storing gases at pressures exceeding 50 bar, especially exceeding 200 bar, and is provided with electrically conducting stretching material (11). The inventive gas container (1) makes it possible to reach a higher filling level at a given pressure than in prior art. Containers having a small wall thickness can be used without safety risk because gas pressure peaks are reduced inside the container.
Abstract:
Devices and methods for storing hydrogen fuels or other gaseous fuels (e.g. hydrogen). One embodiment of a container (20) for storing gaseous fuels in accordance with an aspect of the invention comprises a high-pressure vessel (22) configured to contain the gas in a high-pressure zone at a pressure significantly above atmospheric pressure (e.g. 300-10,000 psi). The container (20) can also include a storing medium (40) in the vessel (22) and an inlet/outlet line (50) extending through the vessel (22). The storing medium (40) can have a plurality of storage spaces (28) configured to physically bind molecules of the gas to the storing medium (40), and the inlet/outlet line (50) can be a tube (52) extending through the vessel (22) in fluid communication with the storing medium (40). The molecules of the gaseous fuel bind to the storing medium (40), and the pressure in the vessel drives additional molecules of the fuel into vacant spaces within the storing medium . A heater (60) is used to release hydrogen from the medium (40).
Abstract:
A pressure vessel comprises a matrix structure extending in three dimensions. The matrix is in generally hydrostatic (triaxial, or three-dimensional) tension when carrying loading induced by pressure of the compressed fluid stored within a series of voids interlinked at their point of contact in the matrix. A fluid impermeable outer covering surrounds, and is contiguously supported by, the matrix. The pressure vessel can assume an irregular shape. Transfer means, including an artery system, is provided for admitting and discharging the fluid. A solid surface component, while in a liquid phase, can be mounted on the matrix and changed to a solid phase, anchoring the component to the matrix with an integral bond.
Abstract:
The invention relates to a container for storing compressed gas, comprising a gas-proof, metallic outer wall (1) which encloses the hollow chamber designed for storing the compressed gas and has at least one connection (2) for a gas pipe for filling and/or emptying the container. According to the invention, the hollow chamber contains an open-cell metallic foam (3) which is materially connected to the outer wall (1).
