Vanadium Redox Flow Energy Storage: Opportunities and Challenges of the New Cycle
According to our calculations, under long-term cost assumptions, the 6-hour scenario LCOS for vanadium redox flow batteries is 0.213 RMB/kWh, and for lithium batteries is 0.211 RMB/kWh; for the 8-hour scenario, it is 0.190 and 0.186 RMB/kWh respectively—the premium narrows from the current 36% to within 2%, with the 6-hour point being the crossover on this curve.
The real constraint on the industry’s pace is not the battery, but vanadium: even with only a 5% penetration rate in 2035, annual V₂O₅ demand will be 532 thousand tons, 4.8 times the current global production of 110 thousand tons, and China’s low-cost vanadium supply relies heavily on vanadium slag, a steel industry byproduct, with further increases limited by declining rebar production. Vanadium redox flow is not just a "wait for the wind" technology pathway; it is a ternary equation requiring the simultaneous unlocking of "long-duration demand, cost reduction, and resource expansion." The anticipated development rhythm for the industry is: Northwest leads—cost reduction and scale-up—nationwide proliferation, with realization more likely in the medium to long term rather than the short term.
