Sustainable Energy Systems
Australian Flow Batteries (AFB) is a Western Australian energy storage company established in 2022, commercialising Vanadium Redox Flow Battery (VRFB) technology for long-duration energy storage. AFB’s intellectual heritage traces back to the original UNSW vanadium flow battery patents, and its leadership has been involved in the VRFB sector since 2000. In three years, AFB progressed from R&D and engineering through field validation to its first commercial sale and has since expanded from a single hybrid diesel-replacement product into a fully integrated business spanning vanadium processing, electrolyte manufacture, battery system assembly and manufacturing, and long-term renewable energy revenue streams.
AFB is uniquely positioned as the only Australian company pursuing the complete vertical value chain for vanadium flow batteries — from Western Australian vanadium resource, through in-house hydrometallurgical processing, to deployed battery systems on customer sites. Backed by an experienced board spanning energy, resources, government relations and project delivery, AFB is building sovereign Australian capability across critical minerals processing and grid-scale energy storage manufacturing.
Western Australia holds approximately 30% of the world’s known vanadium resources. AFB’s hydrometallurgical process is designed to produce battery-grade vanadium pentoxide (V₂O₅) at significantly lower temperatures than conventional smelting, while also generating high-purity titanium dioxide and iron as co-products. The objective is to establish a commercially viable Australian pathway from vanadium resource through high-purity V₂O₅ and electrolyte production, targeting electrolyte costs below US$1 per litre for vanadium flow battery applications.
