A modular subsea fluid storage unit has a variable-volume inner tank having a rigid top panel and a peripheral wall that is flexible by virtue of concertina formation. The peripheral wall is extensible and retractable vertically while the horizontal width of the tank remains substantially unchanged. A side wall of a lower housing part surrounds and is spaced horizontally from the peripheral wall of the inner tank to define a floodable gap between the peripheral wall and the side wall that surrounds the tank. An upper housing part extends over and is vertically spaced from the top panel of the inner tank and overlaps the side wall to enclose the inner tank. The floodable gap and the upper housing part enhance thermal insulation and trap any fluids that may leak from the inner tank.

Disclosed is an automatic alignment method of a high-pressure gas container in which a high-pressure gas container is loaded on a lift of a cabinet so as to supply a gas from a fabrication (FAB) process facility of a semiconductor to a wafer production line, and then, the high-pressure gas container loaded on the lift is raised, and an end cap of the high-pressure gas container and the center of a connector holder of a gas pipe are automatically aligned.

Disclosed is a method for automatically replacing high-pressure gas barrels, in which when loading a high-pressure gas barrel is loaded on the lift of a cabinet so as to supply gas to the wafer production line in the semiconductor fabrication FAB process facility, at the time point of replacement of the high-pressure gas barrel, a used high-pressure gas barrel is separated from a connector holder and then a new high-pressure gas barrel is connected to the connector holder.

A movement plan producing system that produces a movement plan for a hydrogen filling vehicle includes: a residual hydrogen amount information acquisition portion that communicates with a plurality of vehicles using hydrogen gas as fuel to acquire residual hydrogen amount information indicating a residual hydrogen amount in a hydrogen tank of each of the vehicles; a positional information acquisition portion that acquires positional information indicating the position of each of the plurality of vehicles; and a plan producing portion that produces the movement plan for making the hydrogen filling vehicle fill at least some of the plurality of vehicles with hydrogen using the acquired residual hydrogen amount information and the acquired positional information.

Various embodiments provide an end-to-end gaseous fuel transportation solution without using physical pipelines. A virtual pipeline system and methods thereof may involve transportation of gaseous fuels including compressed natural gas (CNG), liquefied natural gas (LNG), and/or adsorbed natural gas (ANG). An exemplary pipeline system may include a gas supply station, a mother station for treating gaseous fuels from the gas supply station, a mobile transport system for receiving and transporting the gaseous fuels, and user site for unloading the gaseous fuels from the mobile transport system. The unloaded gaseous fuels can be further used or distributed.

A multiply-redundant system that prevents a driver from starting and/or moving a vehicle if a compressed natural gas fill system is not correctly and completely disconnected from the vehicle. One or more sensors in combination with one or more optional microswitches combine to lock-out the vehicle's ignition or otherwise prevent it from starting and/or moving. For different levels of safety, different combinations of sensors can be used with the lowest level having a single proximity sensor sensing the presence or absence of a high-pressure fill hose. The highest level of safety being achieved by having separate proximity sensors on the fuel fill hose fitting, the gas cap cover and a manual safety valve along with a redundant microswitch. An optional override that may be restricted as to the number of times it can be used can allow starting with a faulty sensor in order to allow maintenance.

Disclosed is a device for automatically opening or closing a gas barrel valve. The device includes: a main plate installed so as to move up and down and to align the position of a gas barrel loaded in a cabinet; a gas barrel connecting portion installed on the lower portion of the main plate, separating an end cap from the gas barrel and storing the end cap, and then automatically screw-coupling a connector holder to a gas spray nozzle; a valve handle unit installed on the main plate so as to rotate around a first shaft and rotating a valve handle of the gas barrel such that the valve handle is locked or unlocked, while encompassing the valve handle of the gas barrel; and a valve handle opening or closing unit installed on the upper portion of the main plate so as to operate the valve handle unit in a direction, in which a valve of the gas barrel is opened.

A valve for a pressurized fluid, including a body housing a fluid circuit including an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user apparatus, the circuit including a control valve controlling the flow rate in the circuit, the control valve being operated by a mobile actuating member to command the opening or the closing thereof, the valve including a first wireless remote communications electronic member using electromagnetic data waves, wherein the first electronic communication member is secured to a support component mounted to move on the body of the valve between at least a first position and a second position with respect to the body.

A system and a method for sensing hydrogen charge state of a fuel cell electric vehicle are provided. The system includes an infrared transmission unit that transmits a fuel door sensing infrared signal for sensing a fuel door opened while charging hydrogen and a nozzle sensing infrared signal for sensing a charging station-side hydrogen charging nozzle connected to a hydrogen charging inlet of a vehicle. An infrared reception unit receives the fuel door sensing infrared signal and thereafter, reflected on a fuel door and the nozzle sensing infrared signal transmitted from the infrared transmission unit and thereafter, reflected on the hydrogen charging nozzle. A controller determines that the vehicle is being charged with hydrogen when sensing an open state of the fuel door and a hydrogen charging inlet connection state of the hydrogen charging nozzle.

A gas supply apparatus includes: a mounting portion installed on a cabinet; a gas supply portion installed on the mounting portion so as to be raisable and lowerable; and a gas container fixing portion fixing a gas container to the gas supply portion, wherein the gas supply portion includes a compressed gas association (CGA) fastening module that is installed on the mounting portion and is detachable from the gas container, and the CGA fastening module includes: a case; an end cap housing rotatably installed on the case; a CGA connector housing installed on the case so as to be disposed adjacent to the end cap housing; a gasket detection sensor installed on a sensor installation mount of the case and disposed under the CGA connector housing; and a power transmission portion spaced apart from the end cap housing and connected to the end cap housing and the CGA connector housing.
