> Because any pressurized gas energy storage is either including some advanced heat storage or is just venting the heat created during compression a thermal-energy-storage system cools the CO2 to an ambient temperature https://energydome.com/co2-battery/ https://energydome.com/co2-battery/ diagram has water as the heat storage. Tanks of water get efficient at energy storage due to square-cube scaling.
