Abstract:
A vessel of a heat storage and release apparatus, the vessel comprises a shell comprising a metallic material, the shell having an elongated shape with a first end region and a second end region remote from the first end region, and an internal surface defining a cavity configured to contain a heat storage and release device and to guide gas-flow; a first opening through the shell for a flow of gas at high temperature and high pressure, the first opening being located in the first end region; a second opening through the shell for a flow of gas at low temperature and high pressure, the second opening being located in the second end region; and a lining of thermally insulating material adjacent to the internal surface and only partially covering the internal surface, the lining being located at least in the first end region.
Abstract:
A vessel is disclosed, the vessel including a main body having a hollow interior for receiving a fluid therein, wherein at least a portion of the hollow interior includes a filling material disposed therein to minimize a rate of flow of the fluid from the main body, wherein the filling material is at least one of a porous structured material and a granulate material.
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.

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.
Abstract:
When hydrogen is taken out, para-hydrogen having a low energy is converted into ortho-hydrogen having a high energy, and a cooling effect of endothermy of the para-ortho conversion is utilized for maintaining the temperature within a hydrogen storage device low. For accomplishing such a system, there is provided a hydrogen storage device for storing a liquid hydrogen, wherein a porous magnetic body serving as a para-ortho conversion catalyst is arranged in a hydrogen circulation.

Abstract:
A flexible pressure vessel is constructed from at least one pair of upper and mating lower dome shaped cell portions. The dome portions are molded from sheets of resilient material and joined together by radio frequency welding or high-strength adhesives. Upper and lower passageway portions extend outwardly from each cell portion to the surrounding sheet material. When the cell portions are joined the passageway portions are joined to form a passageway for connection to a valve or another cell. Upper and lower rings surround the upper and lower cell portions to provide reinforcement for the cells. First and second blankets of heavy-duty fiber reinforced material are attached over the upper and lower cell portions and stitched in place with heavy-duty stitching extending through the resilient material surrounding the cell portions. Cell shaped sponges impregnated with absorbent materials are encased in liquid and gas impermeable plastic tubing and inserted into the cells prior to joining of the cell portions. Heat-reflecting plastic film or metal foil is inserted between blankets and the cell portions. The heavy duty stitching is high-pressure loop and lock braiding. The passageway has a cross-section of between 0.050 and 0.100 inches. An apparatus and method are described for constructing the flexible pressure vessel.
Abstract:
Devices and methods for storing hydrogen fuels or other gaseous fuels. One embodiment of a container for storing gaseous fuels in accordance with an aspect of the invention comprises a high-pressure vessel configured to contain the gas in a high-pressure zone at a pressure significantly above atmospheric pressure. The container can also include a storing medium in the vessel and an inlet/outlet line extending through the vessel. The storing medium can have a plurality of storage spaces configured to physically bind molecules of the gas to the storing medium, and the inlet/outlet line can be a tube extending through the vessel in fluid communication with the storing medium. In operation, the high-pressure vessel is pressurized with a gaseous fuel (e.g., hydrogen) to a pressure significantly above atmospheric pressure (e.g., approximately 3,000-10,000 psi). The molecules of the gaseous fuel bind to the storing medium, and the pressure in the vessel drives additional molecules of the gaseous fuel into vacant spaces within the storing medium or in other regions of the vessel.
Abstract:
A method and apparatus for economically storing and transporting coal mine methane gas is presented. The apparatus utilizes converted propane tankers. Standard propane tankers are filled with activated carbon or commercial carbons with a high volumetric methane adsorption capacity. The methane gas is compressed by a smaller compressor at the well and loaded into the converted tanker. At least three converted tankers are utilized in this method, one being loaded at the well, one discharging its methane gas at the end-user, and one being transported in between the well and the end-user. The truck used to transport the converted tankers has a bi-fuel system adding to the economy of the method and apparatus. Utilizing this apparatus and method of storage and transportation will reduce greenhouse emissions from the mine and from the power plants, and will provide the owner and operator with numerous tax credits and clean air incentives. It also provides the public with a cheaper source of cleaner burning fuel for large public utilities and other large end-users.
Abstract:
The invention concerns a process for the manufacture of an explosion protection system for a container for inflammable liquid for gaseous substances, whereby individual sections on the surface of a foil strip that is made of a material with good heat-conducting properties, are permanently bent out of the plane of the untreated foil strip; from the such treated foil strip, at least one three-dimensional filling piece with a large interior surface is manufactured by division and/or deformation and said filling piece is inserted into the container, therefore filling at least the major part of the interior space of the container, as well as an explosion protection system of that kind.
