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.
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.
The capital cost of flow battery includes the cost components of cell stacks (electrodes, membranes, gaskets and bolts), electrolytes (active materials, salts, solvents, bromine sequestration agents), balance of plant (BOP) (tanks, pumps, heat exchangers, condensers and rebalance cells) and power conversion system (PCS).
Since other batteries have a fixed energy to power (E / P) ratio, the architecture of flow batteries enables energy and power to be decoupled, which can be adjusted with the amount of the electrolytes and the sizes of the total electrode areas, hence the power rating is based on the stack size or number.
The vanadium redox flow battery (VRFB) is arguably the most well-studied and widely deployed RFB system. At the time of writing, there are approximately 330 MW of VRFBs currently installed around the world with many more systems announced or under development, including a 200 MW/800 MWh plant in Dalian, China [15, 16].
