Abstract: This invention is a cryogenic fluid transportation and supply system and method for transporting the cryogenic fluid in a liquefied state and alternatively offloading the cryogenic fluid as compressed gas and liquid. The system includes a mobile support means, and a cryogenic storage vessel for storing the cryogenic fluid as liquid. To deliver the cryogenic fluid as compressed gas, the system includes a piston-type pump, a heat exchanger, a compressed gas conduit and a compressed gas connection fitting. To deliver the cryogenic fluid as liquid, the system includes a liquid line in communication with the cryogenic storage vessel and a liquid cryogenic fluid connection fitting. An internal combustion engine of a motor vehicle used for moving the mobile support means may power the pump and an optional fan for the heat exchanger. A hydraulic system may be used to transfer the power between the internal combustion engine and the pump.

Abstract: The invention provides a method for supplying a cryogenic fluid to a network of two or more cryogenic fluid receiving stations, wherein a cryogenic liquid is routed to cryogenic fluid receiving stations in a single cryogenic vessel and is dispensed to the cryogenic fluid receiving stations as either a cryogenic liquid, a compressed gas, both a cryogenic liquid and a compressed gas, or as a mixture of a cryogenic liquid and a compressed gas.
