A system for dispensing a gaseous fuel from a liquefied fuel and a method for operating such a system are provided. The system includes a storage tank, a pressure sensor, a dispenser, a temperature sensor, and a vapor supply unit. The storage tank stores a liquefied fuel including phases of liquid and vapor. The pressure sensor is configured to measure a vapor pressure inside the storage tank. The dispenser is configured to receive the liquefied fuel and dispense the gaseous fuel to a receiving tank. The temperature sensor is configured to measure temperature of the dispenser. The system further includes a vapor supply unit fluidly coupled with the storage tank and configured to provide the vapor of the liquefied fuel from the storage tank into the dispenser or in thermally contact with at least one portion of the dispenser.

An inspection apparatus A for a hydrogen gas dispenser includes a receiving-side gas flowing unit 1 including a receptacle 11 configured to be connected to a nozzle C1 of a hydrogen gas dispenser C and an inspection unit including a rate-of-pressure-rise inspection unit 2 configured to measure a rate of pressure rise of hydrogen gas from the hydrogen gas dispenser C and a dispensed-amount inspection unit 3 configured to measure a dispensed amount of the hydrogen gas. The inspection apparatus A for a hydrogen gas dispenser is capable of measuring a dispensed amount and a rate of pressure rise of the hydrogen gas dispenser.

A fluid dispensing system generally comprising a dispensing nozzle coupled to a supply conduit; the dispensing nozzle detachably connected to a receiver; a receiver identification device associated with the receiver; an electrical identification circuit being contact-based and including the receiver identification device; an electronics module connected to the supply conduit and arranged to communicate with the electrical identification circuit whereby connection of the dispensing nozzle to the receiver completes the electrical identification circuit and permits communication of at least a unique receiver identifier associated with the receiver identification device to the electronics module.

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.

A quick-fill apparatus for use with a valve assembly, and related methods of filling a pressure vessel, are disclosed. A valve assembly may be affixed to a pressure vessel, and may include a receptacle, a fill valve and an overfill valve. Preferred examples of the apparatus comprise a body, a valve trigger pin, a vent trigger pin and a handle. A valve engagement end of the body may be releasably securable within the receptacle. At that point, moving the handle to the on position causes the valve trigger pin to force the fill valve to an open configuration, and causes the vent trigger pin to force the overfill valve to a fluid venting configuration. A rigid fill tube may be in fluid supplying communication with a fuel supply port of the body. The fill tube and the handle may be elongated and extend in a shared direction.

Device and method for filling pressurized-gas tanks, comprising a fluid transfer circuit provided with an upstream end intended to be connected to a source of gas and at least two parallel downstream ends intended to be connected to distinct tanks that are to be filled, the transfer circuit comprising a temperature regulating member for regulating the temperature of the gas transferred from the source towards the downstream ends, the gas temperature regulating member being positioned in the transfer circuit upstream of the at least two downstream ends, which means to say that the gas temperature regulating member is common to the at least two downstream ends, characterized in that the at least two downstream ends of the circuit each comprise a respective control member for controlling the flow rate and/or the pressure of the transferred gas and configured to control the flow rate and/or the pressure in each of the downstream ends independently.
