Abstract:

Compressed carbon dioxide energy storage (CCES), a new type of compressed gas energy storage technology, has the advantages of high energy storage density, low economic cost, long operation life, negative carbon emissions, etc. It is suitable for large-scale, long-term energy storage systems for construction and sustainable development in China and has a broad development prospect. This paper intuitively shows the advantages of a CCES system compared with a compressed air energy storage system. It introduces the operation principle, system performance, and applicable scenarios of cross-critical, supercritical, and liquid CCES system. Similarly, this paper also expounds on the influence of key operating parameters on the system performance and its improvement method, and further introduces the improved system and improvement effect of CCES coupled to other external energy systems. Finally, the advantages and development direction of the CCES system is analyzed. This paper aims to summarize the current research results of CCES technology, point out its advantages and disadvantages, guide subsequent scholars to study the CCES systems, and provide reference for the experiment and demonstration of CCES systems.
