摘要:
Embodiments of the present invention relate to compressed gas storage units, which in certain applications may be employed in conjunction with energy storage systems. Some embodiments may comprise one or more blow-molded polymer shells, formed for example from polyethylene terephthalate (PET) or ultra-high molecular weight polyethylene (UHMWPE). Embodiments of compressed gas storage units may be composite in nature, for example comprising carbon fiber filament(s) wound with a resin over a liner. A compressed gas storage unit may further include a heat exchanger element comprising a heat pipe or apparatus configured to introduce liquid directly into the storage unit for heat exchange with the compressed gas present therein.

A composite pressure vessel and method of manufacture. A composite pressure vessel comprises a multi-component mandrel that is integrated into the vessel, thereby becoming a permanent part of the pressure vessel, and comprises a cylinder and dome ends. Dome ends are made from custom molds with a fiber reinforced polymer. Components of the mandrel may be pieced together with a joining resin. The mandrel comprises a permeation barrier coated on the inside by spraying with elastomer resin, for example. Filaments are wound onto the mandrel, allowing any length of cylinder section to be made for the pressure vessel.

A cellular reservoir flexible pressure vessel is formed as a series of closely packed tubes fitted into a pair of opposing end caps. The end caps have individual receptacles sized and shaped to receive the tube ends that are secured with adhesive or radio frequency welding. At least one end cap has a passageway for connection of the vessel. The flexible pressure vessel has a pressure relief device comprising a reduction in thickness of one end cap at a predetermined location. When subjected to overpressure it fails at the predetermined location. Other pressure relief devices include: a projecting member on the vessel surface, a weakened section of the passageway, a weakening or an absence of braiding material or hoop winding at a predetermined location on the vessel surface or along the passageway, a weakening or spreading of fibers in either the reinforcing panels or the flexible blankets covering the vessel.

A vacuum insulated container is constituted by a double-walled receptacle wherein the space between the walls is substantially evacuated to provide vacuum insulation. The outer wall is provided with an opening therein which is used during manufacture to provide access to the space between the walls so that the space may be evacuated. A stopper- or plug-like portion fills the opening after the container has been evacuated and is permanently joined or bonded to the surfaces of the opening thereby providing a sealing to maintain the vacuum in the space between the walls. The apparatus and method of manufacturing such a container include means for and the steps of: forming the opening by piercing the outer wall; providing a sealed chamber in which the container may be placed on a movable support after a sealing element is placed on the opening; evacuating the chamber; heating the container in the vicinity of the opening with the sealing element resting therein; and deforming the sealing element to cause it to completely seal the opening and bond to the container wall after it has been heated to a temperature permitting the material to flow.

A semi-ellipsoidal, semi-toroidal, or toroidal shell includes an annular sheet metal wall that is longitudinally segmented so as to include a plurality of annular wall segments. Each of the plurality of annular wall segments is joined to an adjacent wall segment by a respective latitudinal wall weld. Also disclosed is a tank including the shell, a vehicle including the shell, a multi-conic preform used to manufacture the shell, a method for assembling the preform, and a method for manufacturing the shell using the preform.
摘要:
A tank assembly. Said tank assembly comprises a one or more blister assemblies, a shell assembly, a one or more air inlet hoses, a one or more spray equipment and a slurry mixture. Said one or more blister assemblies comprises a first blister assembly and a second blister assembly. Said one or more blister assemblies comprise a one or more draw tubes, a one or more cone flanges, a one or more head assemblies, a one or more shells, a one or more cone assemblies, an air line assembly, a one or more snorkel assemblies, and a separation distance. Said one or more draw tubes comprise a first draw tube and a second draw tube. Said separation distance between said one or more draw tubes is configured to allow said one or more spray equipment to rotate freely on said one or more draw tubes without interfering with one another.

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.
摘要:
An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.
