An iron flow battery is an energy storage system that uses iron ions in a liquid electrolyte to store and release electrical energy. This technology enables the efficient production and consumption of renewable energy sources by providing grid stability and balancing energy supply and demand.
[pdf] China’s first megawatt iron-chromium flow battery energy storage demonstration project, which can store 6,000 kWh of electricity for 6 hours, was successfully tested and was approved for commercial use on February 28, 2023, making it the largest of its kind in the world.
[pdf] Flow batteries are a new liquid-based energy storage technology that is suitable for large-scale energy storage. It has a long life, high safety and excellent flexibility. Although there are issues with size and initial cost, improvements are expected as research progresses.
