Can iron-based aqueous flow batteries be used for grid energy storage?

A new iron-based aqueous flow battery shows promise for grid energy storage applications. A commonplace chemical used in water treatment facilities has been repurposed for large-scale energy storage in a new battery design by researchers at the Department of Energy's Pacific Northwest National Laboratory.

What is an iron-based flow battery?

Iron-based flow batteries designed for large-scale energy storage have been around since the 1980s, and some are now commercially available. What makes this battery different is that it stores energy in a unique liquid chemical formula that combines charged iron with a neutral-pH phosphate-based liquid electrolyte, or energy carrier.

What is Iron-Flow batteries?

This unique feature allows for cost-effective scaling, essential for large-scale applications. Developed using an advanced metal complex and membrane, Iron-Flow Batteries is based at the Paris Flow Tech platform – a premier hub for innovation in continuous flow chemistry.

Why is the development of iron-chloride flow battery a problem?

The development and large-scale commercialization of such an iron-chloride flow battery technology has been hindered hitherto by low charging efficiency resulting from parasitic hydrogen evolution at the negative electrode and high overpotential losses.
