CO2 batteries
CO2 Battery is a long-term energy storage system that uses a large inflatable dome to keep thousands of tons of carbon dioxide in a closed cycle.
With an excess of electricity, the CO₂ is compressed and pumped into the dome, and if it is necessary to generate energy, the gas expands, rotating the turbine and returning electricity to the grid.
The system does not burn the CO₂ and does not throw it out - gas circulates inside the installation, acting only as a working medium, and not as a source of energy.
A standard plant produces 20 MW of power within 10 hours. Life is three times longer than lithium-ion batteries, the cost in 2025 is 30-50% lower.
The design uses only steel, water and CO₂ - without rare earth materials.
