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.
