Recently, the report titled "Storing Energy in Liquids: The Sulfur-Iron Flow Battery Project of ZH Energy," guided by Professors Liu Xing, Yu Zhongfu, and Guo Yiwei from North China Electric Power University, won the first prize in the Beijing regional competition and the third prize in the national final of the 11th National College Students' Energy Economics Academic Innovation Competition. This competition is hosted by authoritative institutions such as the Chinese Society of Double Method (Chinese Society of Preference, Optimization, and Scheduling Method and Economic Mathematics) and was included in the Ministry of Education's "Directory of National College Students' Competitions" in 2023. It is one of the most credible national academic competitions in the field of energy economics in China.

The report systematically reviews the application background of sulfur-iron flow batteries, analyzes the advantages and challenges of this technology compared to traditional energy storage methods, and summarizes the current research on flow batteries through literature review. It then obtains key operational data of the project through corporate research and analyzes the actual performance of the energy storage system in terms of investment returns, operating costs, and application scenarios. In combination with the current market situation, it compares sulfur-iron flow batteries with other energy storage technologies (such as all-vanadium flow batteries and lithium-ion batteries) to assess their cost advantages and potential market share. Furthermore, it uses the Life Cycle Assessment (LCA) method to calculate the carbon footprint of sulfur-iron flow batteries, evaluates their environmental benefits, and analyzes the impact of government subsidies, electricity pricing mechanisms, and market incentive policies on the industrialization of this technology. Finally, through market analysis, it combs through the technological development trends of flow batteries and uses the Technology Readiness Level and "technology benchmarking" method to qualitatively predict the market development path of sulfur-iron flow batteries.

The award-winning sulfur-iron flow battery technology in the energy economics academic competition fully demonstrates its excellent economic value. With a significant cost advantage—reducing the cost of the electrolyte by 85% compared to the all-vanadium system—and balancing safety and economy, it effectively reduces the initial investment and the total life cycle cost of flow battery energy storage, making it an ideal choice for large-scale energy storage. As the world's first company to achieve the engineering application of sulfur-iron flow batteries, ZH Energy will accelerate its commercialization process to build a more economically efficient and safe large-scale energy storage solution.
