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. . While lithium-ion dominates short-duration storage, vanadium redox flow batteries (VFBs) are gaining traction for multi-hour applications. Support CleanTechnica's work through a Substack subscription or on Stripe. Yet another twist in the tangled web of red state – blue state relations. . Redox flow battery costs are built up in this data-file, especially for Vanadium redox flow. 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.
