Global All-Iron Redox Flow Battery Market 2026 by Manufacturers, Regions, Type and Application, Forecast to 2032

According to our (Global Info Research) latest study, the global All-Iron Redox Flow Battery market size was valued at US$ 1161 million in 2025 and is forecast to a readjusted size of US$ 11600 million by 2032 with a CAGR of 39.4% during review period.
All-Iron Redox Flow Battery uses iron salt and water as the electrolyte. When the battery is working, the positive and negative electrolytes are forced to circulate through the respective reaction chambers by their respective liquid pumps, and participate in the electrochemical reaction through the stack to realize the exchange of chemical energy and electrical energy. Conversion, so as to realize the storage and release of electric energy. During charging, ferrous iron (Fe+2) is oxidized to ferric iron (Fe+3) on the positive (positive) pole of the battery and reduced to ferrous metal on the negative (negative) pole of the battery. A porous separator is used to minimize the mixing of positive and negative electrolytes, which helps to increase the Coulombic efficiency of the battery. Positive and negative electrolytes are stored in separate tanks outside the battery, and this electrolyte is constantly pumped in and out of the battery during operation. To convert chemical energy back into electrical energy, the reactions are reversed; at the positive electrode of the battery, ferric iron is reduced to ferrous, and at the negative electrode, metallic iron is oxidized to ferrous. During these charge and discharge cycles, the pH of the positive and negative electrolytes changes significantly. A proton pump ensures that the pH of the electrolyte remains stable and free of any hydroxides. The duration of stored energy can vary independently of power. To increase the duration for an all-iron flow battery, all you need to do is add electrolyte to the tank.
Compared with the high cost of all-vanadium flow batteries, the raw materials of all-iron flow batteries are safe and abundant iron, inorganic salts and water. All-iron flow batteries are not toxic and will not cause explosion risks. The advantages of all-iron flow batteries mean that they will continue to gain the favor of industry investors. The advantages of iron flow batteries determine their broad development prospects.
The direct application of all-iron flow batteries is renewable energy storage. Renewable energy sources such as wind power and solar energy are intermittent and difficult to accurately predict. As a renewable energy storage device, all-iron flow batteries can convert difficult-to-regulate electric energy into valuable electric energy. All-iron flow batteries not only have the function of "peak shaving and valley filling", but also can ensure the safe operation of the power grid.
Under the background of "dual carbon", energy storage, as a key link to achieve the goal, will usher in rapid development. From the existing technology, all-iron flow batteries have been well applied on the power generation side, the power grid side, and the user side. They have a high degree of fit with technical requirements and a fast cost reduction rate. They have very broad application prospects in energy storage.
In 2021, North American ESS signed an agreement with SoftBank's SDenergy, committing to provide it with 2GWh of battery systems by 2026.
