Leading the way in all-vanadium redox flow batteries

Building a new long-term energy storage ecosystem.

HUALUCHUNENG

As the "double carbon" goal becomes a global consensus, new energy sources such as wind and solar power have seen exponential growth. Long-duration energy storage, as a "key piece" in the energy transition, is opening up a billion-level market blue ocean. Vanadium redox flow batteries, with their core advantages of safety, stability, longevity, and environmental friendliness, have become the core force in the long-duration energy storage track. Huasu Energy Storage Group has been deeply engaged in this field, and with the layout of the entire industry chain and hard-core technological innovation, it has injected "vanadium" power into the construction of a new power system.

Race for the track: All-vanadium flow batteries become essential for energy storage

The importance of long-term energy storage is increasingly highlighted under the wave of global energy transformation. Data shows that the market size of all-vanadium flow batteries is expected to reach 8.5 billion yuan in 2025 and will exceed

30 billion yuan in 2030, with an average annual compound growth rate of more than 30%, becoming the fastest-growing sub-segment in the electrochemical energy storage field.

Behind this growth are the dual drives of policy and market. The country's "14th Five-Year Plan" for the Development of New Energy Storage clearly lists all-vanadium flow batteries as a key research and development direction, requiring that the

proportion of long-term energy storage installed capacity be increased to more than 20% by 2030; local governments accelerate the implementation of pilot projects through policies such as electricity price subsidies and green channels for projects,

with as many as 16 100-megawatt-level projects registered in 2023 alone.

Meanwhile, technological breakthroughs continue to lower the threshold of application. The 2024 annual electricity cost has dropped to 0.35-0.45 yuan, a 55% decrease from 2020; the domestic content of core materials has reached 78%; the energy conversion efficiency has increased to 75%-80%; and the cycle life has exceeded 20,000 times, enabling vanadium redox flow batteries to penetrate across the power generation side, the power grid side, and the user side.

Full-chain layout, controlling core links：

Build a 2GWh vanadium redox flow battery industrial base in Qitai County, Xinjiang, to create a "mineral mining → electrolyte preparation → energy storage system integration" vertical industry chain, locking in costs and supply stability from the source. Relying on Sichuan's vanadium resources and regional industry advantages, we will help build the world's largest vanadium battery electrolyte production base.

Technical breakthrough, leading the industry standard：

Based on the technical system of the Chinese Academy of Sciences, and in conjunction with universities such as Sichuan University of Light Industry and Technology, we have built research laboratories to overcome multiple core technological barriers. We have independently developed optimized fuel cell structures and electrolyte flow designs, adopting key materials such as proton exchange membranes and graphite felts, achieving industry-leading levels of over 72 hours of long-term energy storage and a system efficiency of over 85%, with a cycle life exceeding 20,000 times.

Scenario implementation, empowering the entire energy field：

In the field of large-scale energy storage, we have served multiple large projects of central enterprises, providing stable energy storage support for wind and solar power integrated projects; we have launched the country's first all-vanadium flow battery residential energy storage product, achieving 24-hour green power supply through intelligent energy controllers; we have made an appearance at the Bangkok Smart Technology Exhibition, bringing integrated photovoltaic, energy storage, and charging technology to the Southeast Asian market, and contributing to the global zero-carbon goal.

Ecological synergy, cohesion of development synergy：

As a core member of the energy state-owned central enterprise ecosystem, it has in-depth cooperation with leading enterprises such as Huawei, Longi, and Sunshine to create a "device platform service" energy Internet ecosystem for wind and solar energy storage. It has more than 30 core patents and international authoritative certifications such as CE/CB/FCC/ROHS, and provides standardized and customized energy storage solutions for global customers.

Future is promising: anchor a green future and build a new chapter of energy

With the improvement of electrolyte recovery rate and breakthrough in energy density, the cost per kilowatt-hour of vanadium redox flow battery is expected to further decline in 2026, further consolidating the competitive advantage in long-term energy storage field. Hualu Energy Storage will continue to focus on technology innovation and industrial upgrading. It is planned to build a new energy equipment manufacturing base in southern Sichuan in 2026, and promote the scaled application of vanadium redox flow batteries in more scenarios. 微信图片_20251117171248_195_1070.jpg

From family green electricity to grid peak regulation, from domestic base to international market, Hualu Energy Storage always takes "Implementing dual carbon strategy and empowering green development" as its mission, using the vanadium redox flow battery technology to build a bridge between new energy and a better life. In the future, we will continue to work hand in hand with our partners, to stand at the forefront of the global energy transformation tide, and to write a new chapter of a zero-carbon future together!
