Carbon dioxide energy storage (CES) is an emerging compressed gas energy storage technology which offers high energy storage efficiency, flexibility in location, and low overall costs. This study focuses on a CES system that incorporates a high-temperature graded heat storage structure, utilizing multiple heat exchange working fluids.
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.
Liquid carbon dioxide can be stored at ambient temperatures, unlike Liquid air energy storage (LAES), which must keep liquid air cold at −192°C, though the CO 2 does need to be kept pressurised.
Transport and storage infrastructure for CO 2 is the backbone of the carbon management industry. Planned capacities for CO 2 transport and storage surged dramatically in the past year, with around 260 Mt CO 2 of new annual storage capacity announced since February 2023, and similar capacities for connecting infrastructure.
