Contact UsA company statement says that iron-chromium flow batteries can be recharged using renewable energy sources like wind and solar energy and discharged during high energy demand. Although pumped-hydro storage is the most widely used technology right now, it cannot fully satisfy China's expanding demand for energy storage, noted the China Daily report.
The iron-chromium battery is a real RFB with energy stored in Fe 2+ /Fe 3+ and Cr 2+ /Cr 3+ couples, which are dissolved in hydrochloric acid. During discharge Fe2+ is oxidized to Fe 3+ and simultaneously Cr 3+ is reduced to Cr 2+.
Thanks to the chemical characteristics of the iron and chromium ions in the electrolyte, the battery can store 6,000 kilowatt-hours of electricity for six hours. A company statement says that iron-chromium flow batteries can be recharged using renewable energy sources like wind and solar energy and discharged during high energy demand.
