← Back to context Comment by mark-r 3 days ago They never mention what advantage CO2 has over any other gas, like plain air? 1 comment mark-r Reply oneiric 3 days ago The fluid in high pressure storage is a liquid, making the storage much cheaper. Liquid N2 (most of air) would require over 40 times more pressure or cold temperatures. Purifying out CO2 or any gas is generally a negligible cost.
