Early attempts to commercialize iron-based systems, such as the Fe–Cr flow battery originally developed by Thaller, were explored by several companies during the 1980s and early 2000s. Currently, the only iron-based systems approaching commercialization are the all-iron (Fe–Fe) systems developed by companies such as ESS and VoltStorage.
Organic chelating agents, e.g. citrate, ethylenediaminetetraacetic acid (EDTA) or phosphonates, can further stabilize iron species in complexed forms, preventing precipitation and enabling broader pH operating windows, but may slow electron transfer kinetics.
