To store energy, the gaseous CO 2 is compressed to around 70 bar, which heats it to around 400 °C. Passing it through a heat exchanger and a thermal store cools the supercritical carbon dioxide gas enough to liquify it. The liquid CO 2 can be stored in this state indefinitely in pressurised cylinders.
