我国液氢制取技术产业化应用获新突破

Core Insights - China's liquid hydrogen technology has achieved a significant milestone with the demonstration application of a 5 tons/day liquid hydrogen production equipment in a civil liquid hydrogen plant in Fuyang, Anhui, which has operated stably for over 168 hours [1][3]. Group 1: Technology Development - The successful development of the 5 tons/day liquid hydrogen production equipment involved overcoming several core technologies, including large-scale efficient hydrogen liquefaction process design, integrated technology for hydrogen conversion and heat exchange, and high-efficiency heavy-load hydrogen gas turbine expansion technology [3][4]. - The equipment has achieved a liquefaction capacity of 5.27 tons/day, with an energy consumption of 11.8 kilowatt-hours per kilogram of liquid hydrogen produced [4]. Group 2: Industry Impact - This achievement lays a solid foundation for China's first "liquid hydrogen production-storage-transportation" industrial chain demonstration, which is expected to significantly promote the development of hydrogen fuel commercial vehicles, green energy, and aerospace sectors [4]. - The advancements in liquid hydrogen technology will also support the subsequent research and development of larger-scale hydrogen liquefaction devices with capacities of 10 to 30 tons/day [4].
