On January 3, 2025, the 3,300 cubic meter alkaline electrolyzer developed independently by China Huadian Ke Gong Group Co., Ltd., a subsidiary of China Huadian, as well as the 500 cubic meter PEM electrolyzer developed in collaboration with the Chinese Academy of Sciences, were officially launched into production. Additionally, a 2.5-megawatt PEM electrolyzer demonstration platform was put into use, marking a new breakthrough in China’s equipment for producing hydrogen through the electrolysis of renewable energy sources. This development is of great significance for accelerating the establishment of a new energy system and achieving the “dual carbon” goals. Peng Suping, an academician of the Chinese Academy of Engineering; Liu Qingxia, an academician of the Canadian Academy of Engineering and dean of the School of Future Technologies at Shenzhen Technology University; Ni Bin, secretary of the Beichen District Committee in Tianjin; Xu Hui, deputy secretary of the district committee and district head; Yan Feng, deputy secretary of the district committee; Li Weidong, deputy district head and secretary of the Party Working Committee of the development zone (in charge of both roles); Wu Shaohua, director of the Strategic Planning Department of the group company; Zhang Yulong, deputy director of the Science and Technology Information Department; Peng Gangping, secretary of the company’s Party committee and chairman; and Li Jianbiao, member of the Party committee, deputy general manager, and chief engineer, attended the event.
In recent years, HuanDian KeGong has thoroughly implemented the new energy security strategy of \"four revolutions and one cooperation\" as well as the requirements of the \"dual carbon\" goals. By focusing on hydrogen production from renewable energy sources and its efficient utilization, it has achieved significant progress in the field of hydrogen energy. Taking the launch of this new product and the activation of this platform as an opportunity, HuanDian KeGong will increase its investment in research and development. It will work to make breakthroughs in a number of key core technologies in areas such as efficient and low-cost electrolytic water splitting for hydrogen production, as well as key materials and core components related to the use of green hydrogen in the production of green ammonia and green methanol. The company will continue to advance the development of alkaline electrolyzers with larger capacity, lower energy consumption, and higher energy density, thereby establishing a competitive advantage across the entire industry chain that integrates wind, solar, hydrogen, storage, ammonia, and methanol production. This will help the group company become a world-class enterprise in the field of clean and low-carbon energy. The newly launched “Huazhen” 3300 Nm³/h alkaline electrolyzer features a high current density, high energy efficiency, and excellent resistance to reverse currents. The operating current density of this product is ≥6000 A/m², which is about 100% higher than that of conventional thousand-cubic-meter electrolyzers; moreover, the weight of the electrolyzer cell is about 50% less compared to traditional electrolyzers of the same scale ； Under full-load operating conditions, the DC power consumption of the electrolyzer is ≤ 4.4 kWh/Nm? ； The electrolyzer load adjustment range is 20%-110%. The overall performance metrics have seen a significant improvement.
The discontinued “Huahan” 500 Nm?/h PEM electrolyzer features high current density, low DC energy consumption, a wide load regulation range, and a long service life. The total precious metal loading on the product membrane electrode is 30% lower than that in conventional electrolyzers ； The current density can reach 30,000 A/m² ； Hydrogen production per cell ≥ 500 Nm³/h ； Input power range: 3%-135% ； Under full-load conditions, the DC energy consumption ≤ 4.35 kWh/Nm? ； Load fluctuation response rate ≥ 20%/s ； The effective reaction area of the single-membrane electrode is ≥3000 cm², the largest in both domestic and international markets, and the overall performance of the product reaches an internationally advanced level. The 2.5-megawatt PEM electrolyzer demonstration platform, which was put into operation during the same period, is currently the most powerful PEM testing platform in the industry. It holds great significance for the development of testing and validation capabilities for megawatt-class electrolyzers in the hydrogen energy sector, and it will provide a solid foundation for the research and development as well as technological advancement of high-power PEM electrolyzers in China.
