The idea of the system is that it can turn carbon dioxide gas into a liquid for easier storage when energy is abundant. When energy is needed, it turns the carbon dioxide back into gas, which then powers an electricity-generating turbine. Crucially, the setup operates as a closed-loop system, meaning that it should release no carbon

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.
