A high-pressure tank includes a liner, a fiber layer, and a protective layer. The liner has an internal space to store a fluid. The fiber layer includes fibers wound around an outer surface of the liner, and a thermosetting resin that has been cured and covers surfaces of the fibers. The protective layer includes a porous member disposed on the fibers, the porous member having a plurality of pores extending through the porous member in a thickness direction of the porous member. The thermosetting resin has entered the pores.

A storage system for storing compressed fluid is described. The system includes an excavation made in the ground, a balloon arrangement mounted within the excavation. The balloon arrangement includes a rebar cage and an inflatable balloon arranged within the rebar cage. The inflatable balloon has a middle portion and two end portions. One end portion includes a balloon inlet port, whereas the other end portion includes a balloon outlet port. The system also includes a filling material fully surrounding the inflatable balloon and configured for providing further reinforcement in conjunction with the rebar cage to the inflatable balloon, and for anchoring the inflatable balloon to the excavation. The system also includes a gas pipe assembly including an inlet gas pipe coupled to the balloon inlet port for filling the inflatable balloon with compressed fluid, and an outlet gas pipe coupled to the balloon output port for releasing the compressed fluid.

An example tank can be used to contain, transport, and/or store fluids, e.g., one or more liquids and/or gases. In one embodiment, the tank includes a plurality of segments collectively defining an interior chamber that retains the fluid(s), each of which includes opposing ends defining beveled mating surfaces. The tank also includes a plurality of endcaps positioned between, and in engagement with, adjacent segments, as well as a plurality of webs that include a series of first webs having a first configuration and a series of second webs having a second, different configuration. The first webs are positioned within the plurality of segments between the ends thereof, and the second webs are positioned within the endcaps. In an alternate embodiment, the tank is devoid of the endcaps, and instead, includes segments defining beveled mating surfaces that intersect at junctures to define four corner sections of the tank.

A gas storage system for storing compressed gas, and method for constructing the system, are described. The system includes a borehole having a first borehole portion and a second borehole portion. An inflatable balloon is arranged within the second borehole portion. An upper support member, mounted on top of the inflatable balloon, is configured for anchoring the inflatable balloon to a sealing material filling the first borehole portion. A lower support member is arranged at the bottom of the inflatable balloon. The system includes an inlet gas pipe for filling the inflatable balloon from the gas compressing system and an outlet gas pipe for releasing the compressed gas. A compacted filling material is placed within a gap formed between the inflatable balloon, the upper support member, the lower support member, and an inner surface of the second borehole portion. One or more filling material pipes extend along the borehole to the gap for providing a filling material thereto.

A tank suitable for storing a product at a cryogenic temperature, including a fluid tight interior barrier, a fluid tight exterior barrier, surrounding the first interior barrier, an intermediary volume interposed between the interior and exterior barriers and at least one insulating layer positioned in the intermediary volume and including at least one thermal insulation mat, with very low thermal conductivity. The intermediary volume contains microspheres outside of the thermal insulation mats and has an enhanced level of vacuum. This solution makes it possible to maintain satisfactory performance in terms of thermal insulation even in the event of a loss of vacuum in the intermediary volume.

Disclosed is a membrane bonding structure for bonding a membrane for forming a sealed wall between first and second surfaces of a storage tank for storing liquefied gas. The membrane bonding structure may comprise: a planar portion panel installed on the first and second surfaces so as to thermally insulate the storage tank; a bonding panel installed on the boundary portion between the first and second surfaces together with the planar portion panel; a first membrane attached to the planar portion panel on the first surface and to the bonding panel so as to seal the storage tank; and a second membrane attached to the planar portion panel on the second surface and to the bonding panel so as to seal the storage tank. The first membrane and the second membrane may be attached to the bonding panel so as to make no direct connection.

A gas tank liner comprises: a cylindrical section formed using a first resin; and a dome section formed using a second resin, the dome section being arranged at each axially opposite end of the cylindrical section, wherein either one of the first resin or the second resin has a higher linear expansion coefficient and higher yield strain than the other, the yield strain being the threshold of strain that, when met, makes the first resin or the second resin incapable of restoring its original state if the first resin or the second resin strains and yields in response to the application of external force.

A dispensing assembly for a pressure dispense package includes a connector having separate and distinct liquid and extraction conduits, and having a pressurization gas conduit. A liner fitment adapter may include a longitudinal bore to receive a probe portion of a connector defining a liquid extraction conduit, and may include a lateral bore to enable removal of gas. Insertion of a connector into a dispensing assembly simultaneously makes fluidic connections between (a) a gas extraction conduit and a dispensing volume; (b) a liquid extraction conduit and the dispensing volume, and (c) a pressurization gas conduit and a space to be pressurized within a pressure dispense vessel.

The invention relates to a tank, in particular a fuel tank, for receiving a liquid in a motor vehicle, comprising an outer wall that forms an internal space for receiving the liquid, at least one volume element situated in the internal space for receiving gas, in particular air, a gas-guiding line between the volume element and the surroundings of the tank for changing the volume of the volume element, and at least one stabilizing assembly for minimizing stresses at kinks of the volume element when evacuating the volume element.

An inflatable structure for gas storage (such as carbon dioxide) includes an inner bladder containing a gas for storage and an outer wall spaced from the inner bladder. An intermediate space between the bladder and the outer wall is pressurized with a gas other than the storage gas (such as air) so that the structure is protected from environmental conditions such as wind and snow loading. A method of using the inflatable structure for storage of a storage gas includes using a blower to inflate the inner bladder with storage gas, and pressurizing the intermediate space with air to have a higher pressure than the inner bladder.
