The present invention relates to a natural gas hydrate tank container loading system for transporting natural gas hydrate, and the present invention provides a natural gas hydrate tank container loading system which enables automated connection of an electric power line and a boil-off pipe, and may automatically connect an electric power line and automatically connect the pipe by simultaneously stacking respective natural gas hydrate tank containers, in order to solve problems of a transportation method using the existing natural gas hydrate tank containers in the related art in that an operation of connecting an electric power line to a refrigerator for minimizing the occurrence of boil-off gas and maintaining a phase equilibrium condition in the tank containers and an operation of connecting the pipe for discharging the boil-off gas need to be manually and individually performed for long-distance transportation of a large amount of natural gas hydrate by using a ship, which causes an inconvenience.

A filling station for pressurized fluids has a storage container and a dispenser supplied thereby, comprising a high-pressure path and a low-pressure path. The storage container is partitioned into separate sections, which are each connected to the input of a high-pressure pump via a first switching valve and to the output of said high-pressure pump via a second switching valve. The first or second switching valves are connected on their pump sides to the low-pressure path of the dispenser via a third switching valve. The output of the high-pressure pump supplies a high-pressure reservoir via a fourth switching valve, which high-pressure reservoir is connected to the high-pressure path of the dispenser via a fifth switching valve.

A Dewar system is configured to liquefy a flow of fluid, and to store the liquefied fluid. The Dewar system is disposed within a single, portable housing. Disposing the components of the Dewar system within the single housing enables liquefied fluid to be transferred between a heat exchange assembly configured to liquefy fluid and a storage assembly configured to store liquefied fluid in an enhanced manner. In one embodiment, the flow of fluid liquefied and stored by the Dewar system is oxygen (e.g., purified oxygen), nitrogen, and/or some other fluid.

Various embodiments are generally directed to a casing connected to a top cap structure that consists of an adapter flange extending to an adapter barrel that is configured to fit wholly within the casing. The adapter barrel can be separated from the casing by an annulus that is filled to a predetermined annulus pressure while an internal chamber defined by the adapter barrel contains a gas having a small molecular size at a storage pressure that is greater than the predetermined annulus pressure.

A method of storing hydrogen involves forming an excavation in the earth and constructing a storage tank therein comprised of integrated primary and secondary containment structures. The primary containment structure composed of a plurality of joinable cylindrical segments, or pre-fabricated sections joined to form a cylinder within the excavation. The secondary containment structure formed by pumping a curable, flowable composition into the cylinder, allowing it to flow out the bottom and up the second annulus to the earth's surface, and then hardening; thereby encasing the primary containment structure. The bottom of the cylinder is sealed with the bottom assembly. The top assembly is attached to the cylinder and tubing and packer are run into the cylinder creating a first annulus between the cylinder and tubing. Top assembly is sealed, fluids circulated out, and the tank dried. Thereafter, the tank is capable of safely storing hydrogen gas.

A fueling station can include an outer housing comprising a housing volume, a first fluid bladder positioned within the housing volume and configured to hold a first fluid, a second fluid bladder positioned within the housing volume and configured to hold a second fluid, a first fluid conduit in fluid communication with the first fluid bladder, a second fluid conduit in fluid communication with the second bladder, a first hose positioned at least partially outside the outer housing and in fluid communication with both the first and second fluid conduits, and a bi-directional first nozzle connected to an end of the first hose opposite the first and second fluid conduits. The bi-directional first nozzle can be configured to simultaneously release fluid from the first hose and to collect fluid into the first hose. The first fluid bladder can be configured to release fluid through the first conduit in response to introduction of fluid into the second fluid bladder via the second conduit. The second fluid bladder can be configured to release fluid through the second conduit in response to introduction of fluid into the first fluid bladder via the first conduit.

A tank for storing liquefied gas, having a shell delimiting a storage volume extending in a main direction which is horizontal in the use configuration of the tank, the tank comprising multiple deflecting walls in the storage volume which extend in an offset manner in the main direction configured to force the fluid to perform at least one back-and-forth movement in the main direction as the fluid passes between the lower end and the upper end of the storage volume, wherein a plurality of these deflecting walls are located in the lower half of the storage volume.

According to some embodiments, a cryogenic storage tank includes a manway formed in a body of the cryogenic storage tank. An inner manway lid is coupled to an inner wall of the cryogenic storage tank and disposed over at least a portion of the manway. An outer manway lid is coupled to an outer wall of the cryogenic storage tank and disposed over at least a portion of the manway. The inner and outer manway lids are configured to retain pressure within the cryogenic storage tank.

An LNG tank is a single-shell LNG tank having one shell and at least one pipe extending from the LNG tank to a tank connection space of the LNG tank. The shell of the LNG tank is substantially surrounded by insulation. The LNG tank has at least one bellow connection surrounding at least part of the length of the at least one pipe for connecting the at least one pipe extending from the LNG tank to the tank connection space. A system for connecting at least one pipe between an LNG tank and a tank connection space thereof is also provided. At least one pipe extends from the LNG tank to the tank connection space and which LNG tank is a single-shell tank having one shell. The at least one pipe is connected between the LNG tank and the tank connection space by at least one bellow connection.

A liquid nitrogen tank includes a tank, a storage rack and a drive component. The tank includes a tank cover, a tank body, a vacuum cavity layer and a heat-insulating cavity layer. The tank cover is disposed to cover on the tank body. An access door is provided on the tank body. A storage cavity is provided in the tank body. The heat-insulating cavity layer is provided on a periphery of the storage cavity. The vacuum cavity layer is provided on a periphery of the heat-insulating cavity layer.
