An apparatus for mobile hydrogen refueling includes a heavy equipment vehicle having a size exceeding highway size constraints and a platform coupled to the vehicle. A hydrogen storage module and a compression module are removably coupleable to the platform. The storage module is configured to store a number of hydrogen tanks. The compression module is configured to compress a flow of hydrogen from a hydrogen tank in the storage module via a manifold to produce a flow of high-pressure hydrogen. A refueling interface is configured to engage a refueling interface of a hydrogen powerplant and to selectively convey a flow of high-pressure hydrogen from the compression module. In some implementations, the compression module can include a chiller configured to cool the high-pressure hydrogen provided to the refueling interface. In some implementations, a power module is configured to provide electric power to at least the compression module and/or the vehicle.

The present invention primarily relates to a loading system (1) configured to transfer a cryogenic fluid (3) from a storage vessel (2) into a receiving vessel (4), the loading system (1) comprising at least one element (17) for circulating the cryogenic fluid (3) in the liquid state which connects the storage vessel (2) to the receiving vessel (4), a processing and/or consumption unit (26) of the cryogenic fluid (3) in the gaseous state originating at least from the receiving vessel (4) and a return line (28) of the cryogenic fluid in the gaseous state which connects the receiving vessel (4) with the processing and/or consumption unit (26), characterised in that the loading system (1) comprises at least one cooling unit (36) of the cryogenic fluid (3) circulating towards the receiving vessel (4) in the circulation element (17), the cold generated by the cooling unit (36) resulting from an evaporation of the cryogenic fluid (3) coming from the storage vessel (2).

A method and system for forming a compressed gas and dispensing it to a compressed gas receiver. The compressed gas is formed from a process fluid provided at a cryogenic temperature. The forming includes pressurizing the process fluid, feeding the pressurized process fluid at still a cryogenic temperature to a heat exchanger and heating it in indirect heat exchange with a thermal fluid which is provided in a reservoir at a thermal fluid temperature above the cryogenic temperature of the pressurized process fluid. Once heated to a suitable temperature the compressed gas may be dispensed to the compressed gas receiver or stored in one or more compressed gas storage vessels for later use.

The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

The invention relates to a device (10) for supplying a fuel consumer (1) of a vehicle (20) with a gaseous fuel. The device (10) comprises multiple pressure accumulators(2) for storing and providing pressurised fuel, as well as a discharge device (3), which fluidically connects the multiple pressure accumulators (2) with the fuel consumer (1). In order to advantageously allow for a utilisation of a temperature change occurring during a fuel discharge, preferably a discharge cold temperature released during the discharge of fuel, according to the invention, the discharge device (3) is thermally coupled to a coolant circuit (4) of the vehicle (20). The invention also relates to a vehicle (20) comprising a device (10) of this type.

A storage tank for cryogenic liquid includes an outer tank constructed of a rigid material and an inner tank contained within and spaced inwardly from the outer tank. A supply line supplies cryogenic liquid to a plurality of cryogenic freezers. A fill line having a diameter greater than the supply line allows the storage tank to be filled at a greater speed relative to filling through the supply line and allows the storage tank to be filled while supply cryogenic liquid to the cryogenic freezers. A level sensor processes an impedance to calculate a level of the inner tank and a reporting unit displays the level and may report the level to a remote server.

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. Following filling, the tank is disconnected and then driven to another location to repeat the filling process with a second vessel that is at a different location.
