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.

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.

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 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.
