Abstract:

Carbon dioxide energy storage (CES) technology is a new physical technology that is based on compressed air energy storage (CAES) and the Brayton power-generation cycle. It has high energy-storage density, long operation life, and compact-system equipment. In addition, it has good development and application prospects. This paper introduces the working principle and basic characteristics of a carbon dioxide energy-storage system and identifies the calculation method and evaluation effect of system round-trip efficiency (RTE) and energy storage density (ESD). The research status of thermoelectrical carbon dioxide energy storage (TE-CES), transcritical carbon dioxide energy storage (TC-CES), supercritical carbon dioxide energy storage (SC-CES), liquid carbon dioxide energy storage (LCES), and the carbon dioxide energy-storage system coupled with other energy systems are summarized by discussing recent relevant domestic and development processes of carbon dioxide energy-storage technology. In addition, the advantages, disadvantages, and adaptive application scenarios of different systems are identified. The research direction, key technologies, and main challenges of carbon dioxide energy storage are summarized. Finally, it identifies the development prospects of carbon dioxide energy storage in technology research and multiscenario application. Presently, a comprehensive analysis shows that the research on carbon dioxide energy-storage technology is mostly theoretical. We need to focus on system optimization design, experimental verification, and industrialized application. Carbon dioxide energy-storage technology is expected to obtain greater development space in the future power energy-storage market.
