The present invention is directed to a new concept for a large-scale high-pressure Honeycomb Set Tank in an ISO container and for its manufacturing facilities. A process for manufacturing a plurality of honeycomb cells with a high degree of accuracy is also provided.

An apparatus is configured to be positioned between a boss and a shell of a pressure vessel. The boss includes a bore therethrough, and the bore has a longitudinal axis. The apparatus includes an annular body and a gas permeable feature. The annular body includes an inner surface configured to abut the boss and an outer surface configured to abut the shell. The annular body has opposite first and second ends relative to the longitudinal axis. The gas permeable feature is provided on the inner surface and extends at least from the first end to the second end. The disclosure also describes a pressure vessel including a shell, and boss, and an apparatus positioned between the boss and the shell. A method for forming a pressure vessel includes mounting a boss on a mandrel, positioning an annular fitting about a neck of the boss, forming a liner, and forming an outer shell.

A non-metallic pressure vessel is disclosed that includes a bottom dome having an upper wall defining an interface channel, a top dome having a lower wall defining a downwardly projecting securement flange dimensioned and aligned for vertical engagement within the interface channel of the bottom dome, and a flexible diaphragm retained within the interface channel of the bottom dome by the downwardly projecting flange of the upper dome.

A gas storage structure includes: a container and a continuous coiled pipe supported by the container, the continuous coiled pipe including a major portion formed of thin walled pipe and a thick walled pipe defining an end of the continuous coiled pipe, the thick walled pipe having a wall thickness thicker than the thin walled pipe, the thick walled pipe being welded at a welded joint to the major portion to place an inner diameter of the thick walled pipe into communication with an inner diameter of the major portion and the thick walled pipe being connected to the container, while the major portion is free of any rigid, such as welded, connections to the container.

An integrated fill system is provided for a vehicle. The integrated fill system can include a receptacle, a cap that mates with the receptacle, and a fill line that is in fluid communication between the receptacle and a container. The integrated fill system can further include a valve between an opening on an end of the container and an end of the fill line to allow one-way fluid communication for entry of compressed material into the container. The integrated fill system can further include a draw line on an opposite end of the container to maintain separate lines for filling and drawing compressed material into/from the container.

The present application discloses a hydrogen station for supplying hydrogen to a tank of a tank-equipped device. The hydrogen station includes: an integrated controller for integrally controlling devices provided in the hydrogen station; a sensing portion for sensing leaked hydrogen which has leaked inside the integrated controller; a ventilation device performing a high ventilation measure of performing ventilation for air inside the integrated controller or an explosion prevention device performing an internal pressure-based explosion protection measure of creating a pressure-increased state inside the integrated controller; and a compressor unit including a compressor, which is used as one of the devices, and a housing, in which the compressor is stored. The integrated controller is mounted on the housing, and is electrically connected to the compressor via a through-hole formed in the housing to control the compressor.

The present invention relates to a sealing apparatus for a high-pressure tank and a high-pressure tank comprising same, wherein the sealing apparatus comprises: a liner configured to accommodate a high-pressure fluid; a connection boss which is a metallic connector provided at an inlet of the liner and includes a first connection boss part coupled to an inner surface of the inlet and a second connection boss part coupled to an outer surface of the inlet and having a tapered shape with a relatively narrow upper side and a relatively wide lower side; and a coupling member configured to come into surface contact with an outer surface of the second connection boss part and having a tilted surface corresponding to a shape of the second connection boss part so that an inner diameter of a lower side is larger than that of an upper side.

The present invention relates to a method for storing, in a closed container, a composition comprising 1,1,1,2,3,3-hexafluoropropane in a liquid/gas state composed of a liquid phase and of a gas phase, characterized in that i) a stream comprising 1,1,1,2,3,3-hexafluoropropane is injected into said container, said stream comprising an oxygen concentration of at most 5000 ppm by volume at a temperature of 25° C., and ii) the container is closed after injection of said stream. The present invention also relates to a container for storing 1,1,1,2,3,3-hexafluoropropane.

In a gas supply system of one embodiment, if first detection information of a high-pressure sensor exceeds a first threshold value, a gas control ECU causes a pressure adjustment range to overlap a second error range of second detection information of a mid-pressure sensor, the second error range being defined with a second threshold value as a reference point. If the first detection information is less than or equal to the first threshold value, the gas control ECU offsets the pressure adjustment range relative to the second error range defined with the second threshold value as the reference point.

A system for dispensing a gaseous fuel from a liquefied fuel and a method for operating such a system are provided. The system includes a storage tank, a pressure sensor, a dispenser, a temperature sensor, and a vapor supply unit. The storage tank stores a liquefied fuel including phases of liquid and vapor. The pressure sensor is configured to measure a vapor pressure inside the storage tank. The dispenser is configured to receive the liquefied fuel and dispense the gaseous fuel to a receiving tank. The temperature sensor is configured to measure temperature of the dispenser. The system further includes a vapor supply unit fluidly coupled with the storage tank and configured to provide the vapor of the liquefied fuel from the storage tank into the dispenser or in thermally contact with at least one portion of the dispenser.
