3D-Printed Flow Batteries

Queen's University Develops a Low-Cost Iron Flow Battery Cell

3D-printed flow batteries are making long-duration energy storage more accessible by reducing the cost and complexity of developing flow battery technology. Researchers at Queen's University Belfast have created a low-cost, 3D-printed iron flow battery cell that can be produced for a fraction of the cost of conventional research systems. The design not only supports iron-based chemistry as an alternative to more expensive battery materials, but also introduces standardized testing methods that enable research groups worldwide to compare results using the same battery platform. This approach aims to accelerate the development of reliable grid-scale energy storage for renewable power.

For businesses, lower-cost battery development tools can reduce research expenses and shorten the path from laboratory testing to commercial deployment. Standardized battery platforms also improve collaboration between research institutions and industry, making it easier to validate new technologies and scale manufacturing. As demand for long-duration energy storage grows, affordable and reproducible battery designs could help accelerate commercialization across the clean energy sector.
