Polaris Market Research & Consulting has released its Flow Battery Market Report 2026-2034. The market was estimated to be worth USD 611.30 million in 2025 and is expected to grow to USD 4,074.68 million by 2034 at a CAGR of 23.46%. The growth is propelled by increasing renewable energy investment, expansion of EV charging infrastructure, and expansion of grid-scale storage.

The recent trends in the market include the rising commercial activities in the market. For example, in March 2025, Japan’s Ministry of Economy approved the first ever redox flow battery from Sumitomo Electric as a grid-scale battery for a power system stabilization project. In November 2025, India’s largest and first MWh-scale vanadium redox flow battery (VRFB) system of 3 MWh capacity was inaugurated on November 11, 2025, supporting India’s journey towards long-duration energy storage (LDES) solutions. In May 2026, ESS Tech successfully commissioned two ESS Iron flow battery units in California’s Central Valley as part of its expansion strategy in the flow battery market.

“With the help of renewable energy integration, long-duration storage demand, and advancements in electrolyte technology, flow batteries are emerging as a scalable energy storage solution. Firms with superior battery technology, production, and installation capabilities will gain a competitive advantage with rising adoption.” — Apurva Agarwal, Senior Electronics & Semiconductor Analyst
