20230089372 · 2023-03-23 ·

Gaseous fueling systems and methods are provided for dispensing fuel to a vehicle or container. The distribution systems speed up the filling process and may eliminate the use of expensive cooling systems required in the art. The methods utilize sequences of filling and emptying the vehicle gas storage tank to control the temperature of the gas inside the tank. These filling and emptying sequences may overlap. The methods repeatedly dispense fuel to the vehicle fuel tank at a first flow rate and for a first period of time and remove fuel from the fuel tank at a second flow rate for a second period of time, which periods may overlap, to maintain fuel temperature within a desired temperature range and until the vehicle fuel tank is filled to a desired level. In addition, the fill-up mass flowrate can be maximized to system capabilities so a fill-up can be completed in about one minute.
