In 2022, the market size is projected to reach a valuation of USD 278 Million. By 2032, the valuation is anticipated to reach USD 1589 Million.

An iron flow battery, also known as a redox flow battery, is a type of rechargeable battery primarily utilized to increase energy storage capacity by expanding the quantity of electrolytes stored in tanks. In this technology, known as an Iron Flow or iron redox flow battery, iron salt serves as the electrolyte and is ionized to store electrical energy through chemical reactions.

Iron flow batteries are considered a compelling solution for large-scale energy storage devices due to their reliance on iron-based materials, cost-effectiveness, and environmentally friendly characteristics. These batteries are emerging as a promising option due to their affordability and ready availability.

Iron flow batteries are designed for high-capacity energy storage systems, finding widespread use in utilities, telecommunications, industrial, and military applications. They are increasingly making inroads into sectors such as residential and electric vehicle charging stations, thanks to their technical advantages over many other battery types, including lithium-ion, lead-acid, and solid-state batteries.

Unlike traditional batteries that store energy within electrode materials, iron flow batteries store energy in liquid electrolytes housed in external tanks, which are then pumped into cells to facilitate electrochemical reactions. One of the significant advantages of flow batteries, including iron flow batteries, lies in their straightforward electrolyte replacement process.

Their storage capacity is determined by the size of the storage tank and can thus be scaled to meet a wide range of energy requirements, from residential to grid-scale applications. In contrast, the size of the electrochemical cell does not significantly impact the iron flow battery’s storage capacity, with energy capacity primarily linked to the dimensions of the storage tanks.
