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. . Redox flow batteries (RFBs) or flow batteries (FBs)—the two names are interchangeable in most cases—are an innovative technology that offers a bidirectional energy storage system by using redox active energy carriers dissolved in liquid electrolytes. Completed in early January, the project is composed of 34 domestically made "Ronghe 1" battery stacks and four groups of storage tanks. . The experts — from South Korea's Ulsan National Institute of Science and Technology, the Korea Advanced Institute of Science and Technology, and the University of Texas at Austin — are working with iron-chromium redox flow batteries. It's a pack type that offers enormous capacity while being. .
