A cryogenic storage system basically includes a first cryogenic storage tank, a second cryogenic storage tank, a fluid transfer line and a cryogenic containment structure. The first cryogenic storage tank has a first predetermined capacity of liquefied gas. The second cryogenic storage tank has a penetration free bottom and a second predetermined capacity of the liquefied gas that is larger than the first predetermined capacity of the first cryogenic storage tank. The fluid transfer line is fluidly connected between the first cryogenic storage tank and the second cryogenic storage tank. The heat exchanger converts liquid exiting the first cryogenic storage tank to a higher pressure gas that is used as a motive force to move liquidized gas out of the second cryogenic storage.

A tank is used in the containment, transport, and/or storage of 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.

The invention is a reservoir for the storage of a pressurized fluid such as compressed air notably to the storage and recovery of energy using compressed air. In particular, the reservoir comprises at least one tube formed of an arrangement of concentric layers (C1, C2, C3, C4). This arrangement comprises, working from the inside toward the outside of the tube, an internal layer (C1) formed of concrete, a layer (C2) formed of steel of thickness E, at least one layer (C3) formed by a winding of steel wires (C3″) on a sublayer (C3′) of concrete, and an external layer (C4) which protects the wires against at least one of physical and chemical damage, and in which the wires are subjected to circumferential (hoop) tensile prestress with at least one of the thickness E and the prestress being rated to withstand the pressure of pressurized fluid.

A method of manufacturing a pressure vessel, may include a preparation step of preparing a boss made of metal; a processing step of processing a concave-convex pattern on an external surface of the boss; and a winding step of winding a reinforcing material around an external surface of a liner including the boss so that the reinforcing material is disposed on the concave-convex pattern, improving quality and durability of the pressure vessel and reducing a defect rate.

A tank container for storing gases, in particular for storing hydrogen in a motor vehicle. The tank container includes a main body which is preferably tubular, and comprises reinforcement elements which are arranged on a wall of the main body and are produced using an additive manufacturing process.

The invention discloses a bimetallic cryogenic membrane storage compartment for liquefied natural gas (LNG) storage. The invention is based on the design of bimetallic membrane panels and two insulating panels to achieve two completely independent insulation spaces, fully meeting the relevant requirements of the amendments to the International Code for the Construction and Equipment of Ships Carrying Liquefied Natural Gas in Bulk (“IGC CODE”) adopted on May 22, 2014. The invention improves the safety of the cryogenic membrane storage compartment, reduces the limitation of free liquid level loading of liquid cargo in the cargo compartment, reduces the application and time consuming of low-temperature resistant glue in the construction process, and adopts the more mature and safe design method of welding bimetallic membrane panels and the environmental protection method of prefabricated foam insulation panels, thus reducing the construction workload, shortening the construction cycle and improving the safety of the equipment.

In a high pressure gas container including a liner, a reinforcement layer, bosses (caps), and openings (vent holes), the reinforcement layer includes an inner side reinforcement layer that surrounds the liner, and an outer side reinforcement layer that surrounds the inner side reinforcement layer, gas guide passages that guide, to the openings (vent holes), a gas leaking from the liner are formed in the inner side reinforcement layer, and the gas guide passages are voids formed between sections of a reinforcing member by arranging alongside one another and stacking the sections of the reinforcing member along the liner.

A hydrogen storage system includes a hydrogen storage alloy containment vessel comprising an external pressure containment vessel and a thermally conductive compartmentalization network disposed within the pressure containment vessel. The compartmentalization network creates compartments within the pressure vessel within which a hydrogen storage alloy is disposed. The compartmentalization network includes a plurality of thermally conductive elongate tubes positioned within the pressure vessel forming a coherent, tightly packed tube bundle providing a thermally conductive network between the hydrogen storage alloy and the pressure vessel. The hydrogen storage alloy is a non-pyrophoric AB.sub.2-type Laves phase hydrogen storage alloy having: an A-site to B-site elemental ratio of not more than 0.5; and an alloy composition including (in at %): Zr: 2.0-5.5, Ti: 27-31.3, V: 8.3-9.9, Cr: 20.6-30.5, Mn: 25.4-33.0, Fe: 1.0-5.9, Al: 0.1-0.4, and/or Ni: 0.0-4.0.

The present invention relates to a heat-insulating structural material, which: firstly, can minimize or prevent a thermal bridge by improving the structure of the connection part of the heat-insulating structural material; secondly, improves insulation performance by arranging a vacuum insulation material inside the core layer of the heat-insulating structural material; and thirdly, increases structural stiffness by forming the core layer from a non-foaming polymer material having excellent structural performance, prevents gas from moving in or out of the vacuum insulation material through the air-tight adhesive structure of the core layer, and can improve fire protection performance so as not to be vulnerable to fire, and thus the present invention is universally applicable to fields requiring insulation ability and structural performance.
