IDTechEx performed an in-depth analysis about redox flow batteries from a technical and market aspect, evaluating their potential to address the evolving stationary energy storage market.
Over the years, different types of electroactive species have been investigated to increase the efficiency of these systems. The first and most used Redox Flow Battery chemistry is the Vanadium redox flow battery. Initially studied by NASA, and further developed in the 1980’s by the research group led by Maria Skyllas-Kazacos at New South Wales in Australia, the Vanadium redox flow battery (VRFB) is today the most studied and manufactured technology within the redox flow battery technology. Besides different types of RFBs, the vanadium technology (and similarly the All-Iron RFB) employs the same electroactive species (vanadium) in both electrolytes, with different oxidation states.
Ferro-Alloy Resources Limited (LON:FAR) is developing the giant Balasausqandiq vanadium deposit in Kyzylordinskaya oblast of southern Kazakhstan. The ore at this deposit is unlike that of nearly all other primary vanadium deposits and is capable of being treated by a much lower cost process.
