China has put the world's largest vanadium redox battery into operation — a unique energy storage system. The Jimusaer Vanadium Flow Battery Energy Storage project, with a capacity of 200 MW and 1 GWh, is the first solution of this scale in the world.

The system is connected to a 1 GW solar power plant and can provide up to five hours of uninterrupted power, which is critical for keeping electricity supply stable when solar and wind output fluctuates. The technology, based on liquid electrolytes, stands out for its safety, durability and scalability.

Unlike traditional lithium-ion batteries, vanadium redox batteries use liquid non-flammable electrolytes, making them safe, long-lasting and suitable for large-scale infrastructure solutions. In addition, such a system can be easily expanded as demand grows.

The complex makes it possible to use an additional 230 million kWh of green energy per year, reducing losses and making the power system more stable. This is an important step toward greater use of renewable energy sources without the risk of outages and losses.
