Existing flow battery energy storage projects

Are flow batteries the future of energy storage?

To address the challenge of intermittency, these energy sources require effective storage solutions, positioning flow batteries as a prime option for long-duration energy storage. As aging grid infrastructures become more prevalent, flow batteries are increasingly recognized for their role in grid stabilization and peak load management.

What are flow batteries used for?

Some key use cases include: Grid Energy Storage: Flow batteries can store excess energy generated by renewable sources during peak production times and release it when demand is high. Microgrids: In remote areas, flow batteries can provide reliable backup power and support local renewable energy systems.

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.

Are flow batteries sustainable?

Innovative research is also driving the development of new chemistries, such as organic and zinc-based flow batteries, which could further enhance their efficiency, sustainability, and affordability. Flow batteries represent a versatile and sustainable solution for large-scale energy storage challenges.

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.

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.
