Abstract: A method for filling tanks with pressurized gas via a filling station comprising at least one source of pressurized gas and a fluid circuit for transferring the gas, comprising a first end linked to the at least one gas source and a second end provided with a transfer line intended to be removably connected to the tanks to be filled, the circuit comprising a first isolation valve, a flow or pressure regulation member, a heat exchanger for cooling the gas transferred to the tank to be filled and a second isolation valve, the method comprising successively filling a first tank then a second separate tank, characterized in that, on completion of the filling of the first tank, the first and second isolation valves are closed to trap a reserve supply of pressurized gas in the circuit between said two valves and in that the reserve supply of gas is used to fill the second tank.

Abstract: The invention relates to a station and method for filling a tank with a fuel gas. Said station includes at least one fuel gas source store and a gas transfer system having a first upstream end connected to the source store(s) and a second downstream end that is in fluid communication with the tank. The gas transfer system includes at least one control valve, characterized in that the at least one source store includes a rigid outer wall and a flexible sealing wall that is arranged inside the space defined by the rigid outer wall. The flexible wall defines a storage space for the fuel gas. The first upstream end of the system is connected to the storage space defined by the flexible wall.
