Dalian, China-based vanadium flow battery (VFB) developer Rongke Power, has completed a 175MW/700MWh project, which they are calling the world’s largest vanadium flow battery project.
Located in Ushi, China, the project will provide various services to the grid, including grid forming, peak shaving, frequency regulation and renewable integration.
Rongke Power’s vanadium flow batteries can provide continuous energy storage for over 10 hours and the company says they are highly recyclable and adaptable, support various sizes of projects, from utility-scale to commercial applications.

According to Rongke in a release, the installation represents a significant leap forward in renewable energy integration, supporting grid stability while enabling the widespread adoption of clean energy sources.
The company adds that the project’s completion marks a turning point in the energy storage industry, demonstrating the viability of large-scale vanadium flow battery systems for long-duration applications.
Days following completion of the project, Rongke Power also announced they had surpassed 2GWh of deployed utility-scale VFB energy storage systems worldwide, representing the largest installation capacity in the VFB sector to date.
Commenting in a release was Philip Krause, senior vice president of Rongke Power: “As we reach this significant milestone, we remain committed to delivering high-performance energy storage solutions that enable the transition to renewable energy. This achievement reflects our dedication to addressing critical challenges in the energy sector and driving forward a more sustainable and resilient energy future.”
According to research published in 2021 in Advances in Smart Grid Power Systems, compared with other chemical energy storage technology, the vanadium redox flow battery has advantages in safety, longevity and environmental protection. It is considered to be one of the most promising energy storage technologies.
Rongke Power has over 450 patents in vanadium flow battery technology, saying their flow battery systems are operational in key regions globally.
Earlier this yea in August, the company announced a VFP gigafactory equipped with fully automated, robotic systems, designed to produce up to 1GW in battery energy storage systems (BESS) annually.
At the time, the company’s VFP capacity was at 1GWh.
