A method consistent with the present disclosure may include: (a) equalizing pressure between a nozzle inner void and a receptacle main inner void by pressing a nozzle check against a receptacle check to open the nozzle check and the receptacle check; (b) extending the nozzle into the receptacle such that a receptacle main body surrounds at least a portion of the nozzle probe; (c) flowing fluid from the nozzle inner void into the receptacle main inner void.

A cryogen storage vessel at an installation is filled with liquid cryogen from a liquid cryogen storage tank that has a pressure lower than that of the vessel. After headspaces of the vessel and tank are placed in fluid communication with another via a gas transfer vessel and are pressure-balanced, a pump in a liquid transfer line connected between the tank and the vessel is operated to transfer amounts of liquid cryogen from the tank to the vessel via the liquid transfer line and pump as amounts of gaseous cryogen are transferred, through displacement by the pumped cryogenic liquid, from the vessel to the tank.

This application relates to 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.

An improved system and method for the automated refilling of cryogenic helium is provided. In one embodiment, the system includes a dewar in fluid communication with a liquid helium cryostat through a cryogen transfer line. A controller regulates operation of a three-way valve to pre-cool the transfer line and to cause gaseous helium to flow to the dewar and force liquid helium through the transfer line into the cryostat. The controller is coupled to the output of a cryogenic level sensor, such that the controller regulates the helium liquid level within the cryostat. During filling cycles, the dewar liquid level is also monitored by the cryogenic level sensor and an alarm sounds if the dewar liquid level is undesirably low. Between filling cycles, the controller is operable to ventilate the dewar through a solenoid vent valve in fixed time intervals to ensure the dewar pressure is sufficiently low so as to not bleed liquid helium into the cryostat.

A mobility includes a storage vessel, a power train configured to generate power using liquid hydrogen stored in the storage vessel, and a control device configured to downwardly adjust a target operating pressure of the storage vessel at a time of entering a refueling preparation mode, compare a supply pressure of the liquid hydrogen supplied to the power train with a target hydrogen supply pressure according to the target operating pressure, and limit the power of the power train in response to the supply pressure of the liquid hydrogen being less than the target hydrogen supply pressure.

A gas filling docking tray having a carrier substrate includes a base surface, a plurality of guide blocks, a plurality of positioning pins, and at least one pair of nozzles. The guide blocks are at least disposed on two opposite sides of the base surface to define a wafer carrier accommodation area, and each guide block includes a vertical portion substantially perpendicular to the base surface and an inclined portion located above and connected with the vertical portion. A height of an apex of each positioning pin relative to the base surface is greater than a height of an apex of the vertical portion and less than a height of an apex of the inclined portion relative to the base surface.

Disclosed is a marine vessel to transport natural gas hydrates (NGH), the marine vessel includes a hull formed from solid NGH and a skeletal structure to support the hull. Additionally disclosed is a container to transport NGH including a block of solid NGH and a skeletal structure to support the block. Further disclosed is a method of fabricating a marine vessel for transporting and storing natural gas hydrates (NGH), the method includes preparing a mold, placing a skin layer in the mold, assembling a skeletal structure in the mold, preparing a NGH slurry, and pouring into NGH slurry into the mold.

A system for filling an LPG vehicle with LPG using an auxiliary bombe is provided. The system may be configured for easily filling a main bombe with LPG even in the hot season (summertime) or the like during which the outside temperature rapidly rises, by using an auxiliary bombe in addition to using the main bombe. The system may also be capable of always smoothly refilling the main bombe with LPG by moving a portion of the LPG in the main bombe to the auxiliary bombe, when the pressure in the main bombe is higher than the LPG filling pressure of a filling gun in the hot season during which the outside temperature rapidly rises, so that the pressure in the main bombe becomes lower than the filling pressure.

A multi-cryostorage system that includes at least two cryocontainers for storing hydrogen. The at least two cryocontainers are connected in hydraulic communication via a cryogenic connecting line, and include a primary storage system having a primary inner tank and a primary outer container, and at least one secondary storage system having a secondary inner tank and a secondary outer container. A heat exchanger is operable to heat the hydrogen, and at least one cryopump is arranged in the primary inner tank to supply unpressurised liquid hydrogen and/or unpressurised gaseous hydrogen in one or more stages at low temperature, to the heat exchanger for delivery to a consumer at a pressure higher than the pressure in the primary inner tank.
