Hyderabad, India, June 04, 2026 (GLOBE NEWSWIRE) -- According to the latest report by Mordor Intelligence, the global redox flow battery market is expected to grow from USD 1.83 billion in 2025 to USD 4.96 billion by 2031. Growth is being supported by stronger policies promoting long-duration energy storage, lower electrolyte financing costs, and increasing corporate demand for storage solutions with extended discharge durations.
Vanadium-based systems continue to hold a significant share of installed capacity, while iron flow batteries are gaining momentum due to their abundant raw materials and simplified supply chains. Utility-scale projects remain the largest application segment, although commercial and industrial deployments are expanding rapidly as businesses seek to reduce peak electricity costs. Asia-Pacific leads the market, while supportive policies in North America and Europe are creating new opportunities for adoption.
Redox Flow Battery Market Trends & Forecast
Regulatory Support Strengthens Market Adoption
Supportive energy policies are encouraging wider participation of energy storage systems in electricity markets. These reforms allow flow batteries to access multiple revenue opportunities and improve project economics. Utilities are also increasingly favoring long-duration storage technologies because they offer greater flexibility and can be expanded without replacing the entire system. As a result, flow batteries are gaining stronger traction across both regulated and competitive power markets.
“The evolving role of long-duration energy storage is bringing greater attention to technologies such as redox flow batteries, with investment and deployment decisions increasingly shaped by grid reliability, renewable integration, and lifecycle considerations. Mordor Intelligence applies a consistent research framework that combines extensive secondary sources, industry engagement, and structured market validation, helping stakeholders assess market developments with a level of transparency and comparability that supports informed decision-making" says Himanshu Vasisht, Senior Research Manager, Mordor Intelligence.
Innovative Financing Improves Project Economics
New financing approaches are helping reduce the upfront cost burden associated with flow battery installations. Leasing models allow developers to spread costs over time while reducing exposure to raw material price fluctuations. The ability to reuse key battery materials further enhances long-term value, making large-scale energy storage projects more attractive to investors and accelerating market growth.
Renewable Expansion Fuels Need for Longer Storage
The rapid growth of solar and wind generation is increasing demand for storage systems that can supply electricity for extended periods. While short-duration batteries remain common, flow batteries are becoming a preferred option for applications requiring longer discharge times and frequent cycling. Their durability and long operational life make them well suited for supporting renewable energy integration.
