Cost of electricity from vanadium flow batteries
In 2023, the average VFB system cost ranged between $400-$800 per kWh for commercial installations – a figure that masks both challenges and opportunities. Vanadium electrolyte constitutes 30-40% of total system costs. . As renewable energy adoption accelerates globally, the vanadium flow battery cost per kWh has become a critical metric for utilities and project developers. In our base case, a 6-hour battery that charges and discharges daily needs a storage spread of 20c/kWh to earn a 10% IRR on $3,000/kW of up-front capex. A new techno-economic model confirms that Vanadium Redox Flow Batteries (VRFBs) are on a clear path to becoming the dominant technology for utility-scale. . Researchers in Italy have estimated the profitability of future vanadium redox flow batteries based on real device and market parameters and found that market evolutions are heading to much more competitive systems, with capital costs down to €260/kWh at a storage duration of 10 hours. Image:. . This technology strategy assessment on flow batteries, released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative.
