Let’s look at some key aspects that make flow batteries an attractive energy storage solution: Scalability: As mentioned earlier, increasing the volume of electrolytes can scale up energy capacity. Durability: Due to low wear and tear, flow batteries can sustain multiple cycles over many years without significant efficiency loss.
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.
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.
When discharging, the stored chemical energy gets converted back to electricity. The external storage allows for independent scaling of power and energy, which is a defining feature of flow batteries. A key advantage of this kind of battery is its ingenious ability to increase energy capacity.
