World's biggest battery being built is in Maine! Massive massive iron-air battery! https://www.canarymedia.com/articles/long-duration-energy-storage/form-energy-set-to-build-worlds-biggest-battery-in-maine https://www.canarymedia.com/articles/long-duration-energy-st... I do think redox-flow batteries are so cool. Something about these vast liquid resivours. The ability to filter out impurities & keep regenerating the battery as it would otherwise age... Neat.
