Poland's energy sector is undergoing a radical transformation. While the country still generates 70% of its electricity from coal *, Warsaw shocked markets last month by greenlighting Europe's largest vanadium flow battery project.
[pdf] The Dalian Flow Battery Energy Storage Peak-shaving Power Station, which is based on vanadium flow battery energy storage technology developed by DICP, will serve as the city's "power bank" and play the role of "peak cutting and valley filling" across the power system, thus helping Dalian make use of renewable energy, such as wind and solar energy.
[pdf] A critical factor in designing flow batteries is the selected chemistry. The two electrolytes can contain different chemicals, but today the most widely used setup has vanadium in different oxidation states.
