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.

Iron-based flow batteries designed for large-scale energy storage have been around since the 1980s, and some are now commercially available. What makes this battery different is that it stores energy in a unique liquid chemical formula that combines charged iron with a neutral-pH phosphate-based liquid electrolyte, or energy carrier.
Among the various existing energy storage systems, redox flow batteries (RFBs) are considered to be realistic power sources due to their scalability, high efficiency and long-life cycles. [] Many types of RFBs based on different redox couples/reactions have been developed, such as iron/chromium (Fe/Cr), [ 3 ] bromine/polysulfide, [ 4 ]
Alkaline zinc-based flow batteries such as alkaline zinc-iron (or nickel) flow batteries are well suited for energy storage because of their high safety, high efficiency, and low cost.
