A fuel delivery and storage method 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.

Disclosed are gas cylinder assemblies for containing pressurized gas. The gas cylinder assembly has a polymeric liner and a low-permeability barrier layer. The polymeric liner a first end portion, a second end portion and a central body. The central body comprises an outer surface and an inner surface disposed between the first end and the second end. The gas cylinder assembly comprises a reinforcement structure wound over the central body. The gas cylinder assembly further comprises a metal foil interposed between the reinforcement structure and central body. The metal foil is configured to reduce permeation of contents of the polymeric liner.

A cryogenic railway tank car includes an outer tank, an inner tank positioned within the outer tank, an internal nozzle, and a pipe. The inner tank includes a shell that defines an opening. The internal nozzle is coupled to the inner tank at least along a perimeter of the opening and extends in a radial direction through the opening and into the inner tank. A space defined by an interior surface of the outer tank, an exterior surface of the inner tank, and an interior surface of the nozzle is configured to hold a vacuum. The pipe is configured to transport the fluid between an exterior of the outer tank and the interior of the inner tank. At least a portion of the pipe extends from the outer tank to the inner tank through at least a portion of the nozzle.

An apparatus, system, and method for temporary fluid commodity transfer stations. A fluid commodity transfer structure can include a base member, a casing, and a fluid commodity transfer system. The fluid commodity transfer system can be configured to dispense a commodity for transloading from opposite sides of the fluid commodity transfer structure. A modular fueling station system can include one or more receptacles operably coupled to a fluid commodity transfer structure to allow a fluid commodity transfer system to utilize each receptacle as a fuel reservoir. The fluid commodity transfer structure can be loaded onto an intermodal transport vehicle, unloaded at a location, deposited at the location, and be operably coupled with one or more receptacles and/or other fluid commodity transfer structures to provide fueling infrastructure for fleet vehicles or allow for the commercial transfer of fluid from one receptable to another as a mobile fluid transfer system.

Disclosed is a compressed-gas storage container for the pressurized storage of hydrogen gas including a wall defining a receiving area for storage of the gas. A gas-guiding device directs at least part of the gas along the inside of the wall wherein the wall acts as a heat exchanger in order to remove heat from the gas as the receiving area is being filled with the gas and to dissipate said heat to surroundings exterior to the gas storage container.

Method of operating a hydrogen dispensing where pressure relief is provided through block and bleed valves. After dispensing hydrogen from a dispensing station where the hydrogen is cooled during dispensing, trapped hydrogen remains in the transfer lines. During the idle time between refueling vehicles, the temperature of the trapped hydrogen increases resulting in an increase in the pressure of the trapped hydrogen. Block and bleed valves operate to relieve the pressure in the transfer lines.

The method of transferring compressed gas at from a first tank to a second tank without decompressing the compressed gas and then re-pressuring the compressed gas comprising filling the second tank with a fluid, connecting a first fluid connection on the first tank to a second fluid connection on the second tank with a first line with one or more first valves, connecting a first gas connection on the first tank to a second gas connection on the second tank with a second line with one or more second valves, opening the first valves and the second valves to allow the compressed gas to pressurize the fluid, and pumping the fluid in the second tank into the first tank, thereby causing the compressed gas in the first tank to be displaced into the second tank.

A method of transferring a liquefied gas under pressure contained in a container into a tank or a gas transport network. The container is connected to a recirculation circuit that includes a heater and a recirculation pump connected in series with the heater, upstream from the heater, and arranged to discharge liquefied gas taken from the bottom of the container into the heater, the method including connecting the container to the tank or to the network, via a circuit for transferring the liquefied gas in the liquid phase and not having a pump; allowing the liquefied gas to be transferred to the tank or to the network via the transfer circuit under the effect of a higher pressure in the container; and operating the pump to compensate for the reduction in pressure inside the container during transfer.

An apparatus and method for supplying gaseous fuel from a tender car to an internal combustion engine on a locomotive comprising storing the gaseous fuel at a cryogenic temperature in a cryogenic storage tank on the tender car; pumping the gaseous fuel to a first pressure from the cryogenic storage tank; vaporizing the gaseous fuel at the first pressure; and conveying the vaporized gaseous fuel to the internal combustion engine; whereby a pressure of the vaporized gaseous fuel is within a range between 310 bar and 575 bar.

A method of transporting natural gas by liquefaction of natural gas at ambient temperature, achieved by mixing the natural gas at high pressure with a hydrocarbon that is a stable liquid at ambient temperature and ambient pressure. The hydrocarbon liquid may be crude oil or a distillate of crude oil. The method includes: liquefaction: mixing the natural gas with the hydrocarbon liquid at an ambient temperature and a high pressure to generate a liquid mixture, which contains the natural gas dissolved in the hydrocarbon liquid; shipping: transporting the liquid mixture using a marine tanker, during which the liquid mixture is maintained at ambient temperature and the high pressure; and regasification: at the destination, releasing a gas from the liquid mixture by lowering the pressure of the liquid mixture. The hydrocarbon liquid may be used multiple times.
