The innovative CO₂ Battery technology offers several advantages, including long operational life, independence from critical minerals such as lithium and cobalt, minimal performance degradation over time, and enhanced energy security. With the successful completion of dome inflation, the project has crossed an important milestone. The commissioning of the 20 MW/160 MWh plant now becomes the next key target in realising this pioneering energy storage initiative.

The plant will be set up in NTPC Kudgi plant premises with a capacity of 160MWhr and represents an important step in NTPC’s broader strategy to diversify its energy portfolio and increase the share of renewable power generation in its total capacity.

Commenting on the development, Shri. Gurdeep Singh, Chairman & Managing Director – NTPC, said “This is a landmark development in the domain of ‘Long Duration Energy Storage’ (LDES). NTPC is proud to be in the technology forefront and setup the ‘CO2 Battery’ at NTPC Kudgi.With several advantages—such as a very long lifetime (>25 years), no reliance on critical minerals like Lithium and Cobalt, topography agnostic design, and minimal performance degradation—unlike BESS, where intricate electrochemistry is involved, and a very high depth of discharge (100%)—successful demonstration of this technology shall open up new vistas in the field of Electrical Energy Storage.”
