New sodium-ion mega-batteries are accelerating the shift away from coal, delivering far lower costs and faster deployment than traditional grid infrastructure. Their improved energy density and ultra-long cycle life make them ideal for large-scale renewable storage. As factories ramp up in China, India, and Europe, analysts say sodium-ion grids could replace coal power far quicker than previously forecast.
