I don’t know much about chemistry, but is there a reason why they are using CO2 as the gas medium instead of something else? I was thinking ambient air would be readily available, and you don’t have to worry about suffocating people if it ruptures. Is CO2 particularly efficient to compress?
Air is no good because it has moisture in it. When you decompress it, it becomes ice, blocking and breaking pipes.
