A gas storage container, such as a gas cylinder, is filled with a gas mixture comprising a first gas and a second gas under pressure by feeding a liquid/solid mixture comprising liquefied first gas and solidified second gas into the gas storage container; closing the gas storage container to the passage of gas into or out from the container; and allowing said liquefied first gas and said solidified second gas to become gaseous within said closed gas storage container. Such a process is easier and more energy efficient as compared to direct compression processes, and is safer and results in less wastage as compared to direct liquid injection processes. |
