Are flow batteries a low-cost long-term energy storage technology?

In an August 2024 report “Achieving the Promise of Low-Cost Long Duration Energy Storage,” the U.S. Department of Energy (DOE) found flow batteries to have the lowest levelized cost of storage (LCOS) of any technology that isn’t geologically constrained. DOE estimates that flow batteries can come to an LCOS of $0.055/kWh.

Are flow batteries still king?

With most energy transition technologies, cost is still king. Innovators in the flow battery space have been working hard to develop options that compete with both lithium-ion and vanadium, the dominant flow battery chemistry available on the market today. That work seems to be paying off.

Are flow batteries a viable alternative to lithium-ion?

Flow batteries are emerging as a lucrative option that can overcome many of lithium-ion’s shortcomings and address unmet needs in the critical mid- to long-duration energy storage (LDES) space. With most energy transition technologies, cost is still king.

Why is a flow battery important to China's Energy Future?

It also plays an important role in regulating energy supply and frequency, making it a key component of China’s sustainable energy future. Rongke Power, a pioneer in flow battery technology, previously developed the 100 MW/400 MWh Dalian system in 2022, the largest of its kind at the time.

Are flow batteries paying off?

That work seems to be paying off. In an August 2024 report “Achieving the Promise of Low-Cost Long Duration Energy Storage,” the U.S. Department of Energy (DOE) found flow batteries to have the lowest levelized cost of storage (LCOS) of any technology that isn’t geologically constrained.

Are flow batteries a competitor to lithium-ion?

Flow batteries that use domestically produced organic material would change the calculus and emerge as true competitors to lithium-ion. What has made it hard is that organic materials typically degrade quickly under strong reducing or oxidizing conditions – in other words, when charging and discharging a battery.
