The cost comparison between flow batteries and lithium-ion batteries over time involves several factors, including initial costs, long-term efficiency, and performance durability.
FB manufacturing cost need to be around <200 USD/kWh – but are at between (non-subsidized) V-FB deployments? Electrolyte cost on 5 year-average are between 180-200 USD/kWh for commercially
Researchers from MIT have demonstrated a techno-economic framework to compare the levelized cost of storage in redox flow batteries with chemistries cheaper and more abundant than incumbent vanadium.
The flow battery price conversation has shifted from "if" to "when" as this technology becomes the dark horse of grid-scale energy storage. Let''s crack open the cost components like a walnut and see what''s inside.
Since 2018, attracted by its low electrolyte cost, our team have been working on the legendary Fe-Cr redox flow battery system, which was first invented by Dr. Lawrence Thaller of US NASA in 1975, to develop a low-cost flow battery product.

The capital costs of these resulting flow batteries are compared and discussed, providing suggestions for further improvements to meet the ambitious cost target in long-term.
In this work, an iron-cadmium redox flow battery with a premixed iron and cadmium solution is developed and tested. The influence of acid composition on electrolyte stability has been investigated, and the capital cost of the Fe/Cd RFB is analyzed.
Flow batteries are more cost-effective for long-duration applications due to their scalability and cost structure. Lithium-ion batteries dominate short-duration applications due to performance but may struggle to match the cost reductions of flow batteries.
While this might appear steep at first, over time, flow batteries can deliver value due to their longevity and scalability. Operational expenditures (OPEX), on the other hand, are ongoing costs associated with the use of the battery. This includes maintenance, replacement parts, and energy costs for operation.
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. Yet, their long lifespan and scalability make them a cost-effective choice in the long run.
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.
Flow batteries also boast impressive longevity. In ideal conditions, they can withstand many years of use with minimal degradation, allowing for up to 20,000 cycles. This fact is especially significant, as it can directly affect the total cost of energy storage, bringing down the cost per kWh over the battery’s lifespan.
This includes maintenance, replacement parts, and energy costs for operation. Flow batteries, with their inherent advantageous design, have less stringent temperature and cycling requirements, potentially reducing OPEX compared to other technologies. A critical determining factor in the cost per kWh of flow batteries is the system’s lifespan.
