Recently, technology giant Google announced a long-term partnership with Italian energy storage company Energy Dome to deploy carbon dioxide energy storage technology . So what is CO2 energy storage?
Carbon dioxide energy storage is a kind of gas-liquid mutual conversion and two-state synergistic energy storage technology. Its basic principle is to use the surplus electricity to compress the carbon dioxide gas at normal temperature and pressure into liquid in the low period of power consumption, and store the heat energy generated in the compression process. In the peak period of power consumption, the stored heat energy is used to heat the liquid carbon dioxide to the gaseous state to drive the turbine to generate electricity. The invention relates to a
carbon dioxide energy storage system , which mainly comprises a carbon dioxide storage tank, a compressor, a turbine and a heat and cold storage subsystem. As a new energy storage technology,
carbon dioxide energy storage can store energy up to 16 + hours and release energy up to GW level, which is suitable for large-scale long-term energy storage.
