On December 8, 2023, the domestic \"5 tons/day hydrogen liquefaction system cryogenic tank\" developed independently by Aerospace Hydrogen Energy Technology Co., Ltd., affiliated with the Sixth Academy of China National Space Administration, was successfully manufactured in Beijing. This product is the core component of a large-scale hydrogen liquefaction system equipped with a continuous conversion heat exchanger; it represents a significant technological breakthrough in China’s field of efficient storage and transportation of liquid hydrogen, and its performance in terms of intelligence and energy consumption per unit is on par with international advanced levels. Academician Bao Weimin, Chairman of the Science and Technology Committee of the China Aerospace Science and Technology Corporation; Academician Long Lehao from the First Academy of Aerospace; Wang Wanjun, President of the Sixth Academy of Aerospace, Vice President Zhu Qi, and Chief Economist Wang Feng; Xu Zheng, Deputy Director of the Beijing Science and Technology Innovation Promotion Center; leaders from large energy companies such as Sinopec and CNPC; as well as representatives of the management of relevant units under the Sixth Academy of Aerospace and company shareholders, all attended the launch ceremony. Wang Chenggang, director of Institute 101 of the Sixth Academy and chairman of Aerospace Hydrogen Energy, presided over the ceremony. The launch of this \"5 tons/day hydrogen liquefaction system cryogenic tank\" has led to breakthroughs in a number of key technologies in the production of liquid hydrogen equipment, including the \"liquid nitrogen pre-cooling – hydrogen Claude cycle refrigeration liquefaction process\", \"integration of large-scale deep-cold horizontal cryogenic tanks\", \"high-capacity and high-reliability hydrogen turbine expanders\", \"continuous high-efficiency ortho-para hydrogen conversion heat exchangers\", and an advanced intelligent control system that combines fault diagnosis, automatic start/stop functions, and adaptive control under varying operating conditions. More than 20 intellectual property rights have been established as a result. It achieves independent design and integration of core components such as hydrogen turbine expanders, control systems, catalysts, and continuous heat exchangers, featuring high heat exchange efficiency, large production capacity, and safety and reliability. “The domestically produced 5-ton/day hydrogen liquefaction system cryogenic tank is expected to come online in 2024. Once in operation, it will raise the capacity level of hydrogen liquefaction equipment in China to a new level, while also significantly reducing the costs associated with hydrogen storage and transportation. It will contribute to the development of a new energy system that includes sources, grids, loads, and storage facilities, providing an important technical and equipment foundation for promoting the transformation and upgrading of China’s energy structure and thus boosting the development of the country’s hydrogen energy industry. At the ceremony, Bao Weimin, Long Leihao, Wang Wanjun, Xu Zheng, Zhu Qi, Wang Feng, and Wang Chenggang jointly unveiled the plaque for the \"Domestically produced 5-ton/day hydrogen liquefaction system cryogenic tank\".
