A fluid bypass method for controlling the temperature of a non-petroleum fuel, the fluid bypass method includes: providing a fuel at a pressure sufficient to effect a desired flow rate to a vehicle, the fuel being at a liquid or substantially supercritical thermodynamic state requiring further heat addition in a vaporizer; and diverting a bypass stream with partial or no vaporization to a heat exchanger as a cold fluid on a cold side of the heat exchanger. The method further includes providing a remainder stream of the fuel to the vaporizer; mixing the remainder stream outflowed from the vaporizer with the cold fluid outflowed from the cold side of the heat exchanger to form a combined fuel stream; and providing the combined fuel stream to the heat exchanger as a warm fluid on a warm side of the heat exchanger.

A method for dispensing liquefied fuel, the method including: providing a non-petroleum fuel as a liquefied fuel to a storage tank; increasing pressure of the liquefied fuel to a target pressure using a pump disposed within the storage tank, where a first portion of the liquefied fuel is bypassed around or at least partially around a heat exchanger, and a second portion of the liquefied fuel is discharged to the heat exchanger, where the heat exchanger is configured to warm the second portion of the liquefied fuel. A dispenser is provided that incorporates a control system that allows coordinated fueling of one or more vehicles simultaneously, where the heat exchanger uses only the fuel itself without external refrigeration to manage final dispensing temperature and the fueling station does not include a storage subsystem disposed between the pump and the dispenser.

A system for producing and dispensing pressurized hydrogen includes: a hydrogen generator, in particular an electrolyser, a hydraulic drive, two or more hydrogen storage tanks, and a hydrogen dispensing unit, wherein each of the hydrogen storage tanks is capable of discharging hydrogen at a constant pressure by movement of an internal piston, wherein at least one of the hydrogen storage tanks is arranged to act as compressor by actuation of the internal piston by the hydraulic drive, and wherein at least one of the hydrogen storage tanks is arranged to act as a constant pressure tank for storing and discharging hydrogen at a constant pressure.

The invention relates to a transport container for helium, comprising an inner container for receiving the helium, an insulation element that is provided on the exterior of the inner container, a coolant container for receiving a cryogenic liquid, an outer container in which the inner container and the coolant container are received, and a thermal shield which can be actively cooled with the aid of the cryogenic liquid and in which the inner container is received, wherein a peripheral gap is provided between the insulation element and the thermal shield, and said insulation element comprises an electrodeposited copper layer that faces the thermal shield.

A method is provided for filling a fuel storage system of a motor vehicle with fuel at a relatively high pressure. The fuel storage system has a main tank, which can be filled by way of a main filling line until a limit pressure has been reached, and an auxiliary storage device. If the filling line is connected to a supply station, which provides fuel at a pressure exceeding the tank limit pressure, a tank shut-off valve provided in the filling line will be closed in time before the limit pressure is reached in the main tank and an auxiliary tanking valve is opened in an auxiliary storage device filling line branching off from the main filling line upstream of the tank shut-off valve and leading to the auxiliary storage device. The auxiliary storage device is configured to receive fuel at a higher pressure than the above-mentioned tank limit pressure. The auxiliary storage device is connected downstream of a shutoff valve, which is provided in a supply line leading to a consuming device and which is closed during a filling operation of the main tank, to the supply line such that the consuming device can be operated from the auxiliary storage device even when the shut-off valve is closed.

A method for supplying helium to at least one end user is disclosed by feeding helium from at least one container of helium to an end user through at least one supply system, wherein a mass flow meter and a pressure transmitter, in electronic communication with a programmable logic controller measures an amount of helium being supplied to the at least one user, provides the amount to the programmable logic controller which provides a signal to the at least one end user of an amount of helium that remains in the at least one container and the temperature therein.

A system and method is disclosed for storing a fluid in a storage vessel in liquefied form and delivering it in gaseous form to an end user through a supply line. The system comprises a pressure relief circuit for returning the fluid from the supply line to the vessel when predetermined conditions are met. The pressure relief circuit comprises a return line connected to the supply line and the storage vessel, a diversion line to divert the fluid elsewhere and a switching device operable to direct the fluid to either one of the lines, as a function of predetermined conditions.

The present invention relates to a method for removing helium from a pressurized container, wherein supercritical helium is removed from the pressurized container; wherein the removed supercritical helium is actively cooled by means of a cooling device and/or passively cooled by means of a Joule-Thomson expansion; and thereby at least partially forms liquid helium.

An apparatus to refuel a vessel with cryo-compressed hydrogen is disclosed herein. The apparatus includes a refueler controller configured to defuel the vessel prior to a refuel process based on a pressure of the vessel; fill a mixing tank with at least the cryo-compressed hydrogen based on the pressure of the vessel and a pressure of the mixing tank, wherein the mixing tank is connected upstream of the vessel and is structured to include the cryo-compressed hydrogen; initiate the refuel process of the vessel; adjust a temperature of the mixing tank in response to a temperature of the vessel not satisfying a target temperature of the vessel during the refuel process, wherein the temperature of the mixing tank is to be adjusted based on an increase or a decrease of flow of supercritical hydrogen; and end the refuel process in response to the pressure of the vessel satisfying a target pressure of the vessel.
