Existing flow battery energy storage projects

Are flow batteries the future of energy storage?

Flow batteries are emerging as a transformative technology for large-scale energy storage, offering scalability and long-duration storage to address the intermittency of renewable energy sources like solar and wind.

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.

Why do flow battery developers need a longer duration system?

Flow battery developers must balance meeting current market needs while trying to develop longer duration systems because most of their income will come from the shorter discharge durations. Currently, adding additional energy capacity just adds to the cost of the system.

Where do flow battery startups work?

Based on the heat map, we see high startup activity in the USA, followed by the UK and Germany. These flow battery startups work on solutions ranging from grid-scale energy storage and novel battery materials to battery recycling and organic flow batteries.

Are flow batteries a game-changer for large-scale energy storage?

Among these innovations, flow batteries have emerged as a potential game-changer for large-scale energy storage. Recent advancements in membrane technology, particularly the development of sulfonated poly (ether ether ketone) (sPEEK) membranes, have brought flow batteries closer to widespread adoption.

How much CO2 will flow batteries reduce?

The selected projects are expected to commence operations before 2030 and, over their first ten years, are projected to reduce emissions by approximately 476 million tonnes of CO2 equivalent. The project involving flow batteries will be located in France, and more information will be provided soon. Read more information here.
