As a type of energy storage technology applicable to large-scale and long-duration scenarios, compressed carbon dioxide storage (CCES) has rapidly developed. The CCES projects, including carbon dioxide battery in Italy and carbon dioxide storage demonstration system in China, have also been completed.
To analyze andevaluate the technical and economic characteristics of the system comprehensively and accurately, it is necessary to study the economic status of the compressed carbon dioxide energy storage system in its entire life cycle, and tocompareandanalyzethetechnicalandeconomicalaspectsof the compressed carbon dioxide energy storage system.
The CCES projects, including carbon dioxide battery in Italy and carbon dioxide storage demonstration system in China, have also been completed. This paper carries out a comprehensive summary and performance comparison of latest developments in CCES, including theoretical research, experimental studies and demonstration projects.
For liquid carbon dioxide energy storage (LCES) technology, CO 2 is stored as liquid phase in both HP and LP sides of the system, which has high energy storage density and strong operation stability.
On the contrary, during the energy storage process, carbon dioxide is gradually compressed, and the state of the workinguidchangesfromtranscritical tosupercritical; during the energy release process, carbon dioxide is gradually expanded, and the state of the working uid changes from supercritical to transcritical.
Furthermore, based on the storage methods of carbon dioxide, CCES is subdivided into seven types of storage systems: gas-to-gas, gas-to-supercritical, gas-to-liquid and liquid-to-liquid, among others. The research progress of each type of system is discussed. Their performance is compared in tabular form.
