An Experimental Study on Compressed Carbon dioxide Energy Storage

The massive use of renewable energy has driven the development of energy storage. Compressed CO2 energy storage technology is a promising technology. To gain a deeper understanding of the process of compressing carbon dioxide energy storage (CCES) technology, in order to support technological advances, this paper experimentally studied the performance of compressed CO2 energy storage system. The key parameters, such as the pressure of the storage tanks, the power consumption of the compressor, and the power of the expander were investigated.
