00:00. The aqueous iron (Fe) redox flow battery here captures energy in the form of electrons (e-) from renewable energy sources and stores it by changing the charge of iron in the flowing liquid electrolyte. When the stored energy is needed, the iron can release the charge to supply energy (electrons) to the electric grid.
