China launches largest vanadium flow battery energy storage facility ahead of schedule

China has brought its largest vanadium flow battery energy storage facility into operation ahead of schedule. This new facility is regarded as one of the most promising long-term energy storage technologies.

Vanadium flow batteries operate via the redox reaction of vanadium ions and offer advantages such as high safety, a long service life and scalability.

According to Science and Technology Daily, a TV BRICS partner, this new energy storage facility is connected to a 100-megawatt solar power station. The energy storage project has a rated capacity of 200,000 kilowatts and a storage capacity of 1 million kilowatt-hours.

"This milestone has been achieved more than a month ahead of schedule, resulting in an additional 130 million kilowatt-hours of electricity generated," stated project manager Deng Fubin.

The plant’s entry into commercial operation confirms that vanadium flow batteries are now ready for large-scale application in renewable energy systems. According to statistics, once in commercial operation, the project is expected to generate an average of 1.72 billion kilowatt-hours of electricity annually, saving approximately 51.9 metric tonnes of standard coal and reducing carbon dioxide emissions by approximately 1.424 million metric tonnes each year.
