Apparatus and Method for Dispensing a Cryogenic Fluid

An apparatus for cryogenic fluid dispensing, comprising:

• a pressure adjustment mechanism connectable to a tank configured to store a cryogenic liquid within the tank, the tank to which the pressure adjustment mechanism is connectable being positioned to feed the cryogenic liquid to at least one dispenser;
• the pressure adjustment mechanism configured to increase a pressure of the tank from a first pre-selected pressure to a second pre-selected pressure in response to a detection that the cryogenic liquid from the tank is to be fed to the at least one dispenser for filling a vehicle fuel tank so that the cryogenic fluid is outputtable from the tank to the vehicle fuel tank via the dispenser;
• and
• the pressure adjustment mechanism configured to decrease the pressure of the tank from the second pre-selected pressure to the first pre-selected pressure in response to a detection that filling of the vehicle fuel tank is stopped or completed;
• wherein the pressure adjustment mechanism is configured such that the decrease of the pressure of the tank from the second pre-selected pressure to the first pre-selected pressure includes removing at least one cryogenic fluid from the tank to store the removed at least one cryogenic fluid as a compressed gas within a storage unit connectable to the tank, the removed at least one cryogenic fluid including the cryogenic liquid removed from the tank and/or a cryogenic gas removed from the tank;
• and
• wherein the pressure adjustment mechanism is configured such that the increase in pressure of the tank from the first pre-selected pressure to the second pre-selected pressure includes feeding the compressed gas stored in the storage unit to the tank.
