Can flow batteries be used for energy storage?

A modeling framework developed at MIT can help speed the development of flow batteries for large-scale, long-duration electricity storage on the future grid. In the coming decades, renewable energy sources such as solar and wind will increasingly dominate the conventional power grid.

What is a flow battery?

Hundreds of flow batteries are already in commercial use. Almost all have a vanadium-saturated electrolyte—often a mix of vanadium sulfate and sulfuric acid—since vanadium enables the highest known energy density while maintaining long battery life.

Why are flow batteries so popular?

Flow batteries have the potential for long lifetimes and low costs in part due to their unusual design. In the everyday batteries used in phones and electric vehicles, the materials that store the electric charge are solid coatings on the electrodes.

How many mw can flow batteries store a year?

By 2030, flow batteries could be storing about 61 MW h of electricity each year and generating annual sales for producers of more than $22 billion, Zulch said. “We have a big opportunity here. The numbers are staggering.” Energy companies are obvious customers.

Are flow batteries cheaper than other batteries?

On charging, ions from one electrolyte move through the battery’s membrane to the second electrolyte. At large scale, flow batteries are cheaper than other batteries over their lifetimes. Source: Saudi Aramco. Note: The comparison is of the lifetime cost of a 10 MW battery capable of supplying electricity for 4 h at a time.

Where do flow batteries come from?

Flow batteries could account for up to half of that demand. An additional concern for companies outside China and Russia is that 62% of the world’s vanadium is produced in China, and about 20% comes from Russia, Plananska said. Most of this material is generated as a by-product of iron refining.
