Research and design plan of iron-chromium battery energy storage technology

What is an iron chromium redox flow battery (icrfb)?

The iron-chromium redox flow battery (ICRFB) is considered the first true RFB and utilizes low-cost, abundant iron and chromium chlorides as redox-active materials, making it one of the most cost-effective energy storage systems.

Are iron chromium flow batteries cost-effective?

The current density of current iron–chromium flow batteries is relatively low, and the system output efficiency is about 70–75%. Current developers are working on reducing cost and enhancing reliability, thus ICRFB systems have the potential to be very cost-effective at the MW-MWh scale.

What is iron-chromium redox flow battery?

Schematic diagram of iron-chromium redox flow battery. Iron-chromium redox flow batteries are a good fit for large-scale energy storage applications due to their high safety, long cycle life, cost performance, and environmental friendliness.

Is iron and chromium chemistry environmentally benign?

The iron and chromium chemistry is environmentally benign compared to other electrochemical systems, in that the iron and chromium species present have very low toxicity and the dilute, water-based electrolyte has a very low vapor pressure.

Is icrfb a good option for energy storage?

In addition, ICRFB is considered to be one of the most promising directions for cost-effective and large-scale energy storage applications, as its cost can theoretically be lower than that of zinc-bromine and all-vanadium RFBs, giving it the potential for large-scale promo-tion.
