On the other hand, an iron flow battery uses electrolytes made up of iron salts in an ionized form. As iron flow batteries consist of earth-abundant and non-toxic materials, they are environmentally friendly, safe, and one of the most reliable electrochemical energy storage devices.
Battery manufacturers are collaborating with utility companies to implement iron flow battery projects with the aim of eliminating a majority of the diesel-fueled power generation with the environmentally friendly flow battery system. Furthermore, iron flow batteries have a longer asset life than Li-ion batteries.
The Iron Redox Flow Battery (IRFB), also known as Iron Salt Battery (ISB), stores and releases energy through the electrochemical reaction of iron salt. This type of battery belongs to the class of redox-flow batteries (RFB), which are alternative solutions to Lithium-Ion Batteries (LIB) for stationary applications.
In recent times, global-scale flow battery technology adoption is closely linked with the surging energy storage market. Flow batteries help create a more stable grid and reduce grid congestion and fill renewable energy production shortfalls for asset owners.
