The purpose of this data-file is to build up the costs of redox flow batteries, starting from first principles, for Vanadium redox flow batteries. A 6-hour redox flow battery costing $3,000/kW would need to earn a storage spread of 20c/kWh to earn a 10% return with daily charging and discharging over a 30-year period of backstopping renewables.
In aqueous systems, due to the low cost of solvent and salt, energy cost is mainly determined by the active materials as well as the storage tanks. Therefore, the energy cost of flow batteries with different types of active materials varies greatly .
Naturally, the financial aspect will always be a compelling factor. However, the key to unlocking the potential of flow batteries lies in understanding their unique cost structure and capitalizing on their distinctive strengths. It's clear that the cost per kWh of flow batteries may seem high at first glance.
Overall we think that for long-duration, grid-scale electricity storage, redox flow batteries are looking more economical than lithium ion, especially once storage durations surpass 6-8 hours. Our comparison file is here. This data-file contains a bottom-up build up of the costs of a Vanadium redox flow battery.
Existing commercial flow batteries (all-V, Zn-Br and Zn-Fe (CN) 6 batteries; USD$ > 170 (kW h) −1)) are still far beyond the DoE target (USD$ 100 (kW h) −1), requiring alternative systems and further improvements for effective market penetration.
As we can see, flow batteries frequently offer a lower cost per kWh than lithium-ion counterparts. This is largely due to their longevity and scalability. Despite having a lower round-trip efficiency, flow batteries can withstand up to 20,000 cycles with minimal degradation, extending their lifespan and reducing the cost per kWh.
