ABSTRACT:
The fueling station consists of a vacuum insulated storage vessel for storing a large quantity of LNG at low pressure. The LNG is delivered to one of two relatively small volume fuel conditioning tanks where the pressure and temperature of the LNG can be raised or lowered as dictated by the needs of the system. The pressure and temperature in the fuel conditioning tanks are raised by delivering high pressure natural gas vapor thereto from a high pressure bank. The temperature and pressure can be lowered by venting natural gas from the fuel conditioning tanks and/or delivering LNG thereto. The fuel conditioning tanks are connectable to a vehicle's fuel tank via a fill line to deliver natural gas and LNG to the vehicle and to vent natural gas from the vehicle to the fueling station.
