Technical FAQs 4

How do flow batteries store energy?

An external power source (like solar panels or the grid) forces electrons to flow in the opposite direction, causing the positive electrolyte to be reduced and the negative electrolyte to be oxidized. This stores chemical energy in the electrolytes. Several types of flow batteries are being developed and utilized for large-scale energy storage.

Are flow batteries a good option for large-scale energy storage?

Flow batteries have numerous benefits that have made them a potential option for large-scale energy storage. They are well-suited for applications requiring long-duration storage due to their scalability, high energy density and long cycle life.

Are redox flow batteries a viable solution for large-scale energy storage?

Redox flow batteries (RFBs) have emerged as a promising solution for large-scale energy storage due to their inherent advantages, including modularity, scalability, and the decoupling of energy capacity from power output. These attributes make RFBs particularly well-suited for addressing the challenges of fluctuating renewable energy sources.

Do flow batteries have electrolyte degradation?

While all batteries experience electrolyte degradation, flow batteries in particular suffer from a relatively faster form of degradation called “crossover.” The membrane is designed to allow small supporting ions to pass through and block the larger active species, but in reality, it isn’t perfectly selective.
