India’s largest power producer, NTPC Ltd., is taking a step toward sustainable energy storage with the launch of the country’s first carbon dioxide (CO2) battery energy storage project. To be installed at NTPC’s Kudgi plant, the project is part of the company’s drive to support India’s renewable energy transition by ensuring reliable, long-duration storage for solar and wind power.
The 160MWh (megawatt hours) plant, developed with technology from Italian energy storage company Energy Dome and executed by Triveni Turbine Limited, is expected to help stabilise India’s grid by storing excess renewable energy and making it available on demand.
Shri Gurdeep Singh, Chairman & Managing Director of NTPC, described the project as a “landmark development in the domain of ‘Long Duration Energy Storage’ (LDES)”, highlighting its “very long lifetime (>25 year), no need of critical minerals viz Lithium, Cobalt, topography agnostic, minimal performance degradation – unlike BESS where intricate electrochemistry is involved, very high depth of discharge (100%)” as key advantages over traditional battery storage.
