Collapsible containers are an attractive alternative to surface-tension propellant management devices (PMDs) for handling cryogenic liquids, as the collapsible container comparatively may 1) allow higher expulsion flow rates than vanes and sponges, 2) significantly reduce operational complexity, and 3) thermally insulate the propellant from environmental heat leaks. Furthermore, while historical cryogenic collapsible containers suffered from the low ductility of polymer films at cryogenic temperatures, the technology disclosed herein shows that the incorporation of folded patterns into the collapsible container substantially increases the reusability of the cryogenic PMD.

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 system for increasing the efficiency of heating cryogenic fluid flowing in a downstream direction through a fluid conduit includes a heating mechanism, an upstream valve, a downstream valve, and a controller. The heating mechanism heats the cryogenic fluid, resulting in conversion of a portion of the cryogenic fluid into a buoyant flow moving in an upstream direction. The upstream valve is located upstream of the heating mechanism and controls an upstream-valve mass flow rate of the cryogenic fluid. The downstream valve is located downstream of the heating mechanism and controls a downstream-valve mass flow rate of the cryogenic fluid. The controller adjusts the upstream valve to a choked position at which: an upstream-valve non-buoyant mass flow rate substantially matches the downstream-valve mass flow rate, and the upstream valve at least partially blocks the buoyant flow from flowing in the upstream direction past the upstream valve.

A system for dispensing a cryogenic fluid includes a bulk storage tank configured to contain a supply of the cryogenic fluid. A heat exchanger coil is positioned in the headspace of at least one intermediate fluid tank, which contains an intermediate fluid, and is configured to receive and warm a cryogenic fluid from the bulk storage tank via heat exchange with intermediate fluid vapor in the headspace. A buffer tank receives fluid from the heat exchanger coil. A chiller coil is positioned within the intermediate fluid tank and is submerged within intermediate fluid liquid contained within the at least one intermediate fluid tank. The chiller coil receives fluid from the buffer tank and cools it via heat exchange with intermediate fluid liquid within which the chiller coil is submerged for dispensing.

A tank arranged such that an axis is horizontal, and filling portions are arranged at both ends in the axial direction, and both filling portions are configured to inject gas toward an upper portion of an inside of the tank.

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 control method comprises: receiving from a first vehicle, first information including a first required amount of the energy source; receiving from a second vehicle, second information including a second required amount of the energy source; and determining, when a total sum of required amounts of the energy source received from two or more vehicles including the first vehicle and the second vehicle is larger than a remaining amount in a storage reservoir, i) a first reserved supply amount of the energy source for the first vehicle, wherein the first reserved supply amount is smaller than the first required amount, and ii) a second reserved supply amount of the energy source for the second vehicle. The second reserved supply amount is determined within a range where a total sum of the first reserved supply amount and the second reserved supply amount does not exceed the remaining amount.

The invention related to a system for control of a hydrogen refueling station. The control of the hydrogen refueling station is optimized according to a high frequency tank profile in a time period between time A and time B.
