China launches its largest storage plant with vanadium flow batteries

The People's Republic of China inaugurated the country's largest storage plant with vanadium flow batteries, connected to a 100 MW solar plant. The megaproject, which has a capacity of 200 MW, advanced its commercial launch by more than a month under the direction of Deng Fubin, managing to inject an initial extra of 130 million kilowatt-hours (kWh) into the local power grid.

Unlike lithium, this technology stores electricity through chemical reactions in liquid vanadium solutions. The system stands out for its zero risk of fire, almost non-existent degradation after thousands of cycles and an enormous ease of expanding its capacity. This milestone demonstrates that vanadium batteries are now ready for commercial use on a large scale.

The complex is projected to manage 1,720 million kWh annually, making the most of the surplus from clean sources. In ecological terms, this efficiency will result in an annual saving of 519,000 tons of standard coal and will prevent the emission of 1.42 million tons of carbon dioxide (CO2), accelerating regional decarbonization.

With this achievement, broadcast in cooperation with TV BRICS, China consolidates its leadership in sustainable infrastructure. By mitigating the problem of intermittency of renewable energy (when there is no sun or wind), the project demonstrates that the future of global supply will depend on massive, secure and long-lasting storage systems.
