Abstract: A reservoir is filled under pressure with a gas, by introducing a quantity of a gas into an intermediate receptacle (3), liquefying this quantity of gas, upon its introduction into the intermediate receptacle, by heat exchange with a refrigerant fluid, reheating and vaporizing this quantity of gas in the intermediate receptacle by thermal contact with a heat source (15), and placing in fluid communication the intermediate receptacle and the reservoir (2) when the pressure in the intermediate receptacle becomes greater than the pressure in the reservoir.
