A pressurized gaseous and liquified hydrocarbon feedstock storage system method. The system includes a plurality of underground circuits or sections having parallel pipes joined together by radial ends arranged in various configurations to minimize plot space and maximize the amount of pressurized gaseous fuel stored.

A modular tank is provided for storing pressurized gas, such as hydrogen. The modular tank comprises at least two substantially cylindrical cylinders that are arranged parallel side by side, and are fluidly connected to one another by at least one tube. The at least one tube is arranged in a space between the at least two cylindrical cylinders.

A high-pressure container has a body part, and a cap inserted in the body part, and the body part has a cylindrical liner, and a reinforcement layer provided on an outer circumferential surface of the liner for reinforcing the liner. The cap has a contact portion that contacts with an inner circumferential surface of the liner, a through-hole that communicates the inside of the body part with the outside, and a projecting portion that is pressed outward in radial directions of the body part, and bites into the reinforcement layer, so as to inhibit the cap from moving in the axial direction.

A set of fittings for a fuel tank including an elongated stem and a ferrule. The stem includes an elongated coupling body at one end configured to couple within a cavity defined by an end of a fuel tank liner. The ferrule includes a ferrule body having a first ferrule end and a second ferrule end; a lip defining a coupling orifice at the first ferrule end with the stem being operable to extend though the coupling orifice and engaging the lip, and a ferrule cavity defined by the ferrule body that extends between the first and second ferrule ends and opening to the coupling orifice at the first ferrule end and a ferrule opening at the second ferrule end, the ferrule cavity configured to surround the end of the fuel tank liner.

A Venturi filling system having a first filling coupler configured to be coupled to a first set of fittings disposed at a first tank end of a tank; a second filling coupler configured to be coupled to a second set of fittings disposed at a second tank end of the tank; and a Venturi assembly that includes: a Venturi mixing chamber, the Venturi mixing chamber communicating with the first filling coupler; a Venturi nozzle configured to introduce a first flow of fluid from a fluid source to the Venturi mixing chamber of the Venturi assembly; and an suction inlet communicating with the second filling coupler and coupled with the Venturi chamber and configured to receive a second flow of fluid originates from the second filling coupler such that the second flow of fluid flows into the Venturi chamber and mixes with the first fluid flow within the Venturi mixing chamber.

A gases delivery system for medical use is disclosed that has a container configured to house a metal-organic framework material within at least one section of the container. An activation mechanism may be associated with the container. The metal-organic framework material may contain one or more substances such that the one or more substances may be released from the metal-organic framework material when energy is applied to the container via the activation mechanism. The activation mechanism may be a heating mechanism. One or more containers housing metal-organic framework materials may be used in a gases recirculation system.

An assembly for storing and transporting compressed fluid, such as compressed natural gas, that includes a plurality of hexagonally stacked pipe stored in a cargo hold in or on a vessel, that includes a lower support, side supports and a forcing mechanism that presses strongly down on the pipes so that they cannot move relative to themselves or the vessel on which they are placed. The friction between the pipes causes the plurality of pipes to act as part of the vessel in terms of its structure. The stacked pipe is supported by a plurality of spacers, such as convex side up pipe segments for maintaining a gap between adjacent ones of said plurality of pipes in a same row in said stacked pipe. A load equalizer may be located above the plurality of pipes for distributing the compressive force from the forcing mechanism.

A method of selecting a braid configuration for a braided liner. The method includes calculating a size ratio based on the smallest first diameter and the largest second diameter of the liner and selecting a braid material having a tensile strength. The method further includes calculating a strength ratio based on the tensile strength of the braid material and a selected target strength threshold for the braided liner and determining an optimal braid angle for the smallest first diameter portions of the liner based on the calculated size ratio.

Liquefied gas tank that is easy to machine and quick to operate and bag for sealing cable ducts incorporating said tank. The tank is provided with breaking means for inflating sealed compartments composed of a main pipe (1) closed on one side, an outlet pipe (4) inserted on the other side of the main tube through a first end (6) and closed on the distal end thereof, wherein the outlet pipe is provided with a narrowing (5) that defines a breaking point and an internal orifice (8) that extends from the first end of the outlet pipe to the narrowing (5) towards the distal end, and wherein the size of the narrowing (5), the size of the orifice (8) and the length of the outlet pipe (4) are determined such that a force applied on a lever of between 19N and 80N will break the outlet pipe (4) at the breaking point (5), releasing the gas through the orifice (8).
