A gas enclosure of can include a refractory metal liner adapted to surround and enclose a gas to be contained; a ceramic matrix composite cladding; and a diffusion barrier layer disposed between the refractory metal liner and the ceramic matrix composite cladding.

A hydrogen fueling control device and method comprising step S100, obtaining initial parameters of a vehicle-mounted hydrogen reservoir, wherein the initial parameters comprise volume, initial hydrogen pressure, and initial ambient temperature of the vehicle-mounted hydrogen reservoir; step S200, computing a fueling rate and a target pressure for hydrogen fueling according to the initial parameters, wherein the computed fueling rate and target pressure cause the temperature of hydrogen during a hydrogen fueling process to be within a preset safe range; and step S300, controlling a hydrogen fueling station to fuel hydrogen to the vehicle-mounted hydrogen reservoir at the computed fueling rate to the computed target pressure. The control method controls a fueling process by obtaining a fueling rate and a target pressure by means of initial parameters of a vehicle-mounted hydrogen reservoir measured by a hydrogen fueling station, without requiring the real-time communication between the hydrogen fueling station and a vehicle.

An apparatus is provided for the storage and dispensing of a sorbable gas. The apparatus includes a storage and dispensing vessel constructed and arranged for containing a solid-phase physical sorbent medium having a sorbable gas adsorbed by said sorbent medium. The dispensing vessel includes a top head having a dispensing valve coupled to the vessel for discharging the sorbable gas therefrom. The dispensing valve is in fluid flow communication with a wick that extends below the upper third of the vessel top head. The wick collects the sorbable gas for discharge of the gas through the dispensing valve.

Disclosed is a liquefied natural gas storage apparatus. The apparatus includes a heat insulated tank and liquefied natural gas contained in the tank. The tank has heat insulation sufficient to maintain liquefied natural gas therein such that most of the liquefied natural gas stays in liquid. The contained liquefied natural gas has a vapor pressure from about 0.3 bar to about 2 bar. The apparatus further includes a safety valve configured to release a part of liquefied natural gas contained in the tank when a vapor pressure of liquefied natural gas within the tank becomes higher than a cut-off pressure. The cut-off pressure is from about 0.3 bar to about 2 bar.

A plant for delivering hydrogen includes a hydrogen tank and at least one pipe for delivering hydrogen. At least one surface of the hydrogen tank or of the hydrogen delivery pipe is covered with a two-dimensional material mixed with a polydopamine-type polymer.

The invention relates to a housing having at least one current passage that is impervious to high pressure acting from the exterior, e.g. of at least 1000 bar, e.g. up to 8000 bar. The housing has a first housing part and a second housing part that by spaced-apart bearing surfaces that are facing one another, between which at least one insulator is arranged, with the at least one insulator imperviously encompass an inner volume. The housing is opened easily by spacing apart the first housing part from the second one. Generally, the housing parts are electrically insulated from one another by the insulator.
