System Principle
The new CO2 compression energy storage system is a gas-liquid mutual conversion, two-phase collaborative energy storage technology. It is discard of geological conditions and operates at low pressure and temperature levels, offering high reliability and cost-effectiveness. The basic principle involves utilizing surplus power during periods of low electricity consumption to compress CO2 gas at normal temperature and pressure into a liquid phase. This process stores the heat energy generated during compression. During peak periods of electricity consumption, the stored heat energy is utilized to heat the liquid carbon dioxide, converting it back to a gaseous phase. This gas drives turbine to generate electricity.
Compressed Carbon Energy's CO2 compression energy storage system consists of six main components: gas storage system, liquid storage system, compression system, heat storage system, heat exchange system, and expansion power generation system. This new carbon dioxide compression energy storage system possesses complete independent intellectual property rights. It offers a wide range of power levels, capacities, and regional adaptability. It demonstrates excellent economic benefits in large-capacity and long-term energy storage applications, particularly suitable for 1 0MW, 1 00MW, and 1 0OOMW long-term energy storage systems. The key technology for system design and manufacturing is completely independent and controllable, enabling national production of power equipmentÂ
