Can redox flow batteries be used for energy storage?

Adoption of renewable energy sources will need to be accompanied by methods for energy storage. Lithium-ion batteries continue to dominate for portable electronic applications but other technologies are required for long-term and larger-scale storage. Redox flow batteries, the focus of this Review, represent one such technology.

Can flow batteries be used for large-scale electricity storage?

Associate Professor Fikile Brushett (left) and Kara Rodby PhD ’22 have demonstrated a modeling framework that can help speed the development of flow batteries for large-scale, long-duration electricity storage on the future grid.

What is a Technology Strategy assessment on flow batteries?

This technology strategy assessment on flow batteries, released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative.

How can a flow battery increase energy density?

To increase energy density, metal deposition chemistry, with low redox potentials and high capacity, can be adapted to combine with the flow battery (Fig. 1b); these technologies are called hybrid RFBs 12. For example, Li-metal-based flow batteries can achieve a voltage of over 3 V, which is beneficial for high-energy systems.

Are lithium-ion batteries a viable energy storage option for deep decarbonization?

While lithium-ion batteries have been successfully deployed for portable electronics and electric vehicles, the relatively high energy cost and limited ability to decouple power and energy could render that technology uneconomical for long-duration energy storage needed for deep decarbonization 2.

Which eutectic solvent is used in flow batteries?

For instance, specific ratios of FeCl 3 ·6H 2 O and urea are known to form a brown liquid at room temperature 120. Most deep eutectic solvents used in flow batteries are metal-based with a high concentration of active species (3–6 M) 121, in which the metal centre is the redox-active component.
