Combing the excellent performance of carbon dioxide thermodynamic cycle and the reutilization demands for the captured carbon dioxide, the energy storagetechnologies based on carbon dioxide thermodynamic cycle have the potential to play an important role in the future energy system which mainly consists of renewable energies. This paper presents the definition of the energy storage technology based on carbon dioxide thermodynamic cycle, and then classifies this energy storage technology into six types, which are electrothermal energy storage, compressing carbon dioxide energy storage with low, mid and highpressure gas storage, compressing carbon dioxide energy storage with low-temperature and near atmospheric temperature liquid storage, and the constant pressure gas storage energy storage. The state-of-the-art research status, advantages and disadvantages of these technologies are discussed. In general, the compressing carbon dioxide energy storage with low pressure gas storage is most mature, and there are demonstration units constructed. The compressing carbon dioxide energy storage with high pressure gas storageand the electrothermal energy storage have a good overall performance, but their costs are high. The compressing carbon dioxide energy storage with constant pressure gas storage has the highest cycle efficiency, reaching 74%~75%, and the energy storage density is up to 2 (kW·h)/m3, making it one of the most promising compressing gas energy storage technologies.
