Flow batteries – What can you use them for?

August 18, 2020 By Jeff Shepard 2 Comments

flow batteries

Flow batteries are suited for use in several application areas, including utility-scale energy storage, microgrids, renewables integration, backup power, and remote and off-grid power. Flow batteries are highly scalable, and their power and energy ratings can also be scaled independently. They have very little or no self-discharge current. Flow batteries have demonstrated cycle lives of […]
