Combining high performance characteristics and safety with lower levelised-cost-of-storage, flow batteries are the perfect choice for long-duration energy storage projects— at least on paper. But with a history dating back almost 140 years, the technology is suffering from a lack of wide-scale deployment seen by other battery technologies. But the tide is beginning to rise for flow batteries, as Paul Crompton reports.
