Abstract
A re-fueling station is provided for selectively dispensing fuel in the form of liquefied gas or compressed gas. The re-fueling station comprises a storage tank for storing liquefied gas; a positive displacement fuel pump operable to draw fuel from the storage tank and discharge fuel to a flow diverter, which is operable to selectively direct fuel through one of a first outlet or a second outlet; and conduits through which fuel may flow from the first outlet to a heat exchanger and then to a first dispenser for dispensing compressed gas, or from the second outlet to a second dispenser for dispensing liquefied gas. A method is provided comprising operating the fuel pump in a low speed mode when fuel is directed to the first dispenser and operating the fuel pump in a high speed mode when fuel is directed to the second dispenser.
