Grid-scale battery storage

[autofocus111]

Not much talk out there about vanadium reflow batteries these days. I guess they just can't get the tech to be competitive with Li-ion.

>>>By this August, the state will have 1,700 megawatts of new battery capacity -- enough to power 1.3 million homes and, in theory, avert a grid emergency on the scale of last year’s. It won’t be easy. The state’s plan to eliminate greenhouse gas emissions by 2045 may require installing 48.8 gigawatts of energy storage, according to a report by three state agencies -- more than five times the output of all the grid-scale batteries currently operating worldwide. Other countries are also doubling down on batteries, with China on track to increase capacity to 222 gigawatts by the middle of the century from 1.4 gigawatts in 2019. Australia has a pipeline of grid-scale battery projects totaling more than 11 gigawatts, according to BNEF.

Flow batteries have longevity and can be cycled more but they have low energy densities so they won't replace conventional batteries anytime soon. That story is just all hype.

SP50 While the adoption has been very slow and only a handful of these flow batteries have been deployed to date, China seems committed to adding new capacity.The ability to drive down costs will be crucial, and while I agree it will be a tough slog to challenge conventional Li-ion type, I would not write this tech off just yet. >>>Large-scale Vanadium redox flow battery (VRFB
