The researchers modified the redox flow battery electrodes with nanomaterials to achieve a highly efficient grid-scale electricity storage unit. The new approach is scalable and can store electricity from renewables for long or short periods.
The existing flow battery technologies cost more than $200/kilowatt hour and are too expensive for practical application, but engineers have now developed a more compact flow battery cell configuration that reduces the size of the cell by 75%, and correspondingly reduces the size and cost of the entire flow battery.
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.
Electrode materials includes bipolar plates, end-plates and graphite felts. The total costs of flow battery (C RFB) are expressed in terms of $ (kW h) −1 through dividing the costs of all these components (Cstack, Celectrolytes, CBOP and CPCS) by the required energies of the applications (Etotal = P × tdischarge, where P = Vdischarge × tdischarge).
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.
At their heart, flow batteries are electrochemical systems that store power in liquid solutions contained within external tanks. This design differs significantly from solid-state batteries, such as lithium-ion variants, where energy is enclosed within the battery unit itself.
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.

Here we present a new zinc–iron (Zn–Fe) RFB based on double-membrane triple-electrolyte design that is estimated to have under $100 per kW h system capital cost. Such a low cost is achieved by a combination of inexpensive redox materials (i.e., zinc and iron) and high cell performance (e.g., 676 mW cm −2 power density).
The flow battery OPEX, albeit modest, can also contribute to the overall cost. Infrequent though they are, maintenance requirements must also be factored into the project''s budget.
