Overcoming the barriers related to high capital costs, new supply chains, and limited deployments will allow VRFBs to increase their share in the energy storage market. Guidehouse Insights has prepared this white paper, commissioned by Vanitec, to provide an overview of vanadium redox flow batteries (VRFBs) and their market drivers and barriers.
Traditionally, much of the global vanadium supply has been used to strengthen metal alloys such as steel. Because this vanadium application is still the leading driver for its production, it’s possible that flow battery suppliers will also have to compete with metal alloy production to secure vanadium supply.
The membranes employed in vanadium flow batteries can be grouped into ion exchange membranes and physical separators; however, this topic will only focus on ion exchange membranes .
Skyllas-Kazacos et al. developed the all-vanadium redox flow batteries (VRFBs) concept in the 1980s . Over the years, the team has conducted in-depth research and experiments on the reaction mechanism and electrode materials of VRFB, which contributed significantly to the development of VRFB going forward , , .
The most commercially developed chemistry for redox flow batteries is the all-vanadium system, which has the advantage of reduced effects of species crossover as it utilizes four stable redox states of vanadium. This chapter reviews the state of the art, challenges, and future outlook for all-vanadium redox flow batteries. 1.
Flow batteries are generally defined as batteries that transform the electron flow from activated electrolyte into electric current. They achieve charge and discharge by pumping a liquid anolyte (negative electrolyte) and catholyte (positive electrolyte) adjacent to each other across a membrane as Figure 1 shows.
