Performance optimization and cost reduction of a vanadium flow battery (VFB) system is essential for its commercialization and application in large-scale energy storage. However, developing a VFB stack from lab to industrial scale can take years of experiments due to the influence of complex factors, from key materials to the battery architecture.
Vanadium is ideal for flow batteries because it doesn’t degrade unless there’s a leak causing the material to flow from one tank through the membrane to the other side. Even in that case, MIT researchers say the cross-contamination is temporary, and only the oxidation states will be affected.
The United States has some vanadium flow battery installations, albeit at a smaller scale. One is a microgrid pilot project in California that was completed in January 2022.
The bulk of the capital costs for a Vanadium Redox-Flow Battery lie in the costs of the vanadium electrolyte, while the Regenerative Hydrogen-Vanadium Fuel Cell presents a potential for savings by eliminating the need for half of the vanadium electrolyte required by a Vanadium Redox-Flow Battery.
MIT Department of Chemical Engineering researchers are exploring alternatives to today’s popular vanadium-based flow batteries. That process requires a strong analysis of how much the initial capital cost will be, informing future adjustments for maintenance or replacement.
Vanadium use is primarily limited to a single market, the production of steel, which accounts for about 90% of demand , and only China, Russia, and, most recently, South Africa are major exporters .
