To store CO2 as a liquid you either need to chill it or you need to increase the pressure until it becomes a liquid. It takes around 75psi to turn CO2 into a liquid at room temperature.

75 psi seems very low. Numbers I'm seeing online say more like 800-900 PSI.

Ah, you're correct I was turning bar into psi on the charts I was looking at.

		They are storing it at 70 bar, which is a little over 1000 psi.
