The Flexbase Group has begun construction on the world’s largest flow battery system, an 800 MW / 1.6 GWh redox flow battery in Laufenburg, Switzerland. The system, which will be operational by summer 2028, will stabilize electricity flows across national borders and store energy for hours or days. The project is a significant stride for energy storage in Europe and will help manage renewable energy lulls. The flow battery system is a reliable alternative energy storage solution, offering scalability, long cycle life, and safety. It does not rely on critical raw materials, ensuring energy storage security and energy security. The system is also free from fire risks, making it suitable for use in data centers, offices, and staff facilities. The global flow battery market is expected to grow from $0.34 billion in 2024 to $1.18 billion by 2030, with a CAGR of 23%. The project’s success will depend on regulatory frameworks that support long-duration storage technologies like flow batteries.
