Recently, StartUs Insights, a company dedicated to providing data and research reports on global startups, has identified 207 flow battery startups from more than 4.7 million startups and growth - stage companies worldwide through its Big Data and Artificial Intelligence (AI) - driven StartUs Insights Discovery Platform. And it has selected 20 flow battery startups that are worth focusing on in 2025. Shenzhen ZH Energy Storage Technology Co., Ltd. has once again made the list of companies from mainland China (In 2023, Zhonghe Energy Storage was recognized as the only startup company from mainland China among the top 10 most noteworthy flow battery companies globally.)

In this report, StartUs Insights mentioned: "Shenzhen ZH Energy Storage Technology Co., Ltd. is a research and development manufacturer specializing in key materials and equipment for flow batteries. In terms of batteries, ZH Energy Storage's flow batteries store energy in liquid electrolytes and pump them into the battery stack through the battery group to achieve charging and discharging. This mode can achieve better performance and longer discharge time, making it suitable for energy storage applications lasting 6 to 12 hours. In terms of materials, ZH Energy Storage has adopted self - developed high - performance electrodes, low - cost diaphragms, and new - type electrolytes to reduce system costs. In addition, ZH Energy Storage has also developed a energy storage calculator tool called NeLCOS®, which can calculate the input - output ratio of energy storage systems for energy storage customers and investors from the perspective of levelized cost of electricity over the entire life cycle, annual return on investment, and energy storage configuration plan for free. Overall, these solutions enable energy suppliers to utilize renewable energy more efficiently and allow customers to reduce electricity costs."

The platform's report also pointed out that flow batteries are a type of rechargeable batteries that use two liquid electrolytes to store energy. In recent years, the significant progress of flow battery technology is mainly due to technological innovation in the following key areas: Advances in high - performance materials, AI algorithms, and automation have propelled the development of flow batteries. By utilizing nanomaterials in the construction of electrodes and membranes, flow batteries have achieved higher power density and longer lifespan. With the help of AI algorithms, battery performance is optimized and battery life is extended by predicting degradation and correspondingly adjusting operating parameters. In addition, the introduction of automation technology has significantly improved the production and maintenance efficiency of flow batteries, ensuring the consistency and stability of product quality.

At this critical moment of global energy transition, ZH Energy Storage is at the forefront of this transformation, breaking through key core technologies, and promoting the cost - reduction of flow batteries has become the core driving force for the popularization and efficient utilization of green energy. Faced with the highly competitive energy storage market, ZH Energy Storage has launched high - performance and low - cost iron - sulfur flow battery energy storage technology, and has made significant achievements in promoting the globalization layout by entering the global energy storage market with strong technical strength and reaching strategic cooperation in European flow battery energy storage projects. In the future, ZH Energy Storage will always adhere to the principle of technological innovation, continue to focus on the research and development and manufacturing of key materials and equipment for flow batteries, and continuously and steadily advance its international development strategy. It will work with partners to help the global energy green transition and provide global customers with long - lasting, low - cost, and safer energy storage solutions.
