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 set up the ‘CO2 Battery’ at NTPC Kudgi. With several advantages viz. very long lifetime (>25 years), no need of critical minerals viz. Lithium, Cobalt, topography agnostic, minimal performance degradation – unlike Battery Energy Storage System (BESS) where intricate electrochemistry is involved, very high depth of discharge (100%) – successful demonstration of this technology shall open new vistas in the field of ‘Electrical Energy Storage’.
