In a system and a method for pressure management while extracting a liquid from a liquid storage vessel, a liquid and its vapor are provided in liquid storage vessel. The liquid is extracted by a pump from the storage vessel and fed as a liquid flow to a consumer unit. A defined partial flow is separated from the liquid flow downstream of the pump. The pressure of the partial flow is reduced by a pressure regulation means and the partial flow is evaporated by an evaporator. The evaporated partial flow is fed back into the storage vessel.

A gas adsorption/desorption device includes a gastight enclosure filled with a predetermined gas and supplied with no gas from outside or releasing no gas to the outside, and a porous medium disposed in the gastight enclosure. The predetermined gas in the porous medium is released out of the porous medium in response to supply of energy to the porous medium. The porous medium captures the predetermined gas in the gastight enclosure in response to stopping or reducing of the supply of the energy to the porous medium.

A novel tank cryogenic-compatible composite pressure vessel that beneficially utilizes Vapor Cooled Shielding (VCS) is introduced to minimize thermal gradients along support structures and reduces heat loads on cryogenic systems. In particular, the configurations and mechanisms to be utilized herein include: providing for a desired number of passageways and a given thickness of the VCS, reducing the thermal conductivity of the VCS material, and increasing the cooling capacitance of the hydrogen vapors.

The invention relates to a device (10) for holding a pressure cylinder, the device (10) having a frame element (12), a cylinder space (14) for receiving a pressure cylinder and at least one band element (16) for securing a pressure cylinder in the cylinder space (14), the band element (16) being connected to the frame element (12), wherein at least one damping element (20) is connected to the band element (16), the damping element (20) being arranged between the cylinder space (14) and the frame element (12). In this way, the invention provides an improved device (10) for holding pressure cylinders, the device (10) preventing oscillations from being transmitted into the cylinder space (14).

A fuel delivery and storage system is provided. A further aspect employs a remote central controller and/or software instructions which receive sensor data from stationary and bulk fuel storage tanks, portable distribution tanks, and end use tanks. Another aspect of the present system senses and transmits tank or hydrogen fuel characteristics including temperature, pressure, filled volume, contaminants, refilling cycle life and environmental hazards. Still another aspect includes a group of hydrogen fuel tanks which is pre-assembled with sensor, valve, microprocessor and transmitter components, at least some of which are within an insulator.

Measures for monitoring and manufacturing tanks for cryogenic liquids. The tank is manufactured in a way that signal and power lines from a control unit to sensors of the cryogenic tank are integrated with the tank walls. The conductive track structure so formed has a layer structure that uses the naturally occurring or artificially generated insulating layer on the tank wall material as a substrate on top of which conductive paths are formed that connect the sensors to the control unit.

A filling station for supplying vehicles with gas containing hydrogen comprises: a storage unit comprising high pressure gas containers; a compression unit comprising compressors for increasing the pressure of gas for the storage unit; and a supply unit comprising a supply device for supplying a vehicle; a storage circuit for circulating gas from the compression unit to the storage unit; and a filling circuit for circulating gas from the storage unit to the compression unit. The storage circuit comprises a storage pipe network connecting each compressor to each container and at least one storage distributor for selectively associating the compressors and the containers. The filling circuit includes a filling pipe network connecting each container with each compressor and a filling distributor for selectively associating the containers and the compressors. The station further includes control means for controlling the storage and filling distributors.

An organic composite gas storage tank 100 comprises a hollow central portion 106 which is substantially cylindrical and formed integrally with first and second end portions 102, 104, and which defines a longitudinal tank axis 301. The first end portion comprises a hollow truncated conical region which meets the hollow central portion at a first end thereof, the outer and inner radii of the hollow truncated conical region decreasing in a direction along the longitudinal tank axis away from the hollow central portion. An organic fibre winding 107 extends at least between axial positions which coincide with the hollow truncated conical region of the first end portion and the hollow central portion respectively. The first end portion has a higher axial strength than that achievable for hemispherical end portion of a tank of the prior art.

A pressure vessel assembly includes a pressure vessel including a cylinder, a first side dome provided at one end of the cylinder, and a second side dome provided at the other end of the cylinder, a first protector that surrounds an outer surface of the first side dome, a second protector that surrounds an outer surface of the second side dome, and a connector that connects the first protector and the second protector such that the pressure vessel is interposed between the first protector and the second protector. The pressure vessel assembly can help to prevent damage and breakage of the pressure vessel caused by external impact and improve safety and reliability of the pressure vessel.

Provided is a composite inner frame multi-bonded barrel, a shell-integrated projectile propellant tank including the same, and a method for manufacturing the barrel and the tank. The shell-integrated projectile propellant tank may include the composite inner frame multi-bonded barrel including a cylinder portion including a plurality of inner frames bonded together; a dome portion including an upper dome frame and a lower dome frame bonded to an upper end and a lower end of the cylinder portion, respectively; a cylindrical shell coated on an outside of the composite inner frame multi-bonded barrel; and at least one manhole cover sealing a manhole cover coupling hole formed in a center of the upper dome frame or the lower door frame, and the at least one manhole cover has a fluid injection port formed on one side thereof.
