Abstract
A method and apparatus for fueling the onboard storage tank of a vehicle with liquefied natural gas. A liquid cryogen such as liquid nitrogen is fed to a condensing unit to condense natural gas present in a fueling system. Liquefied natural gas is fed into the fueling system and natural gas vapor is recovered from the onboard storage tank of the vehicle and fed to the condensing unit. When the pressure of the onboard storage tanks is sufficient, the liquefied natural gas is fed from the fueling system to the onboard storage tanks.
