Abstract
The present invention uses an on-board source of compressed natural gas (CNG) to pressurize the LNG in the vehicle's LNG storage tanks such that high pressure natural gas can be delivered to the use device. More than one LNG storage tank can be used without increasing the amount of CNG required if the storage tanks are connected together in series so that the upstream storage tank pressurizes the downstream storage tank.
