Flow battery market to grow to $1.41 billion by 2030

The Business Research Company says the flow battery market is gaining momentum as utilities and developers look for longer-duration, safer energy storage tied to renewable power. The market is projected to rise from $0.83 billion in 2025 to $1.41 billion in 2030, with North America leading in 2025 and Asia-Pacific expected to grow fastest. Why it matters: - Flow batteries are positioned as a long-duration storage option for grids that need to absorb more solar and wind power. - The market is expanding as utilities look for systems with scalable capacity, long cycle life and non-flammable chemistry. - Rising grid resilience needs and falling component costs could widen adoption across utility-scale storage projects. What happened: - The Business Research Company released a 2026 report on the global flow battery market covering trends, size, competitive landscape and forecasts through 2035. - The report says the market will grow from $0.83 billion in 2025 to $0.93 billion in 2026. - The report projects the market will reach $1.41 billion by 2030. - The forecast implies a 12.0% CAGR from 2025 to 2026 and a 10.9% CAGR through 2030. - The report says North America held the largest market share in 2025. - The report says Asia-Pacific is expected to be the fastest-growing region over the forecast period. - The report includes coverage of Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, the Middle East and Africa. - The report offers market attractiveness scoring, TAM analysis, company scoring matrices, Excel-based forecasting dashboards, hotspots infographics, key technology analysis and updated graphics and tables. - The Business Research Company included links to a free sample and the full report: Free sample and Full report . The details: - Flow batteries store energy in liquid electrolytes kept in external tanks. - The electrolytes flow through electrochemical cells to generate electricity. - The design allows capacity and power output to be scaled independently. - That flexibility makes flow batteries suitable for grid energy storage and renewable integration. - Historical market growth has been driven by renewable energy deployment, early grid-stabilization efforts, lithium-ion limits for long-duration storage, funding for alternative battery research and pilot projects using vanadium flow batteries. - Future growth is expected to come from demand for long-duration energy storage, more grid-scale storage projects, lower component costs, stronger grid-resilience requirements and supportive government policies. - Expected trends include larger deployments of long-duration storage, tighter integration with renewable energy systems, improvements in electrolyte chemistry and stack design, broader use of modular systems and more demand for safe, non-flammable batteries. - The report links rising solar output to storage demand, citing US Energy Information Administration projections that US solar generation will rise 75% to 286 billion kilowatt hours by 2025 from 163 billion kilowatt hours in 2023. Between the lines: - Flow batteries are still a small market, but the forecast suggests a shift from pilot-stage deployment toward broader commercial use. - The emphasis on safety, duration and grid resilience points to a niche that lithium-ion has not fully covered. - North America’s current lead suggests stronger near-term project activity, while Asia-Pacific’s growth outlook signals broader infrastructure buildout ahead. What’s next: - Utilities, renewable developers and grid operators are likely to keep testing flow batteries in projects that need multi-hour storage. - Continued policy support and component cost declines could determine how quickly the market moves from early adoption to scale. - The company is promoting additional report capabilities, including forecasting dashboards and market scoring tools.
