After four years of dedicated technical research, a team hailing from the National Key Laboratory of Cryogenic Science and Technology at the Technical Institute of Physics and Chemistry, which is part of the Chinese Academy of Sciences, has successfully cracked the key technologies required for developing 5 - ton - per - day liquid hydrogen production equipment. This achievement is a significant milestone as it empowers China to boast independent research and engineering prowess in the realm of large - scale, high - efficiency civilian liquid hydrogen plants. Moreover, it lays a solid foundation for the advancement of even larger - scale hydrogen liquefiers.
The project team has made remarkable technological breakthroughs in multiple areas, notably in the design of large - scale and highly efficient hydrogen liquefaction process flows. Rigorous tests have revealed that core equipment, such as high - speed, heavy - duty hydrogen turbine expanders, are performing exceptionally well. The system integration and control process package for the liquid hydrogen production equipment is protected by independent intellectual property rights. Additionally, the demonstration operation of the core equipment has successfully met the required standards.
This groundbreaking equipment made its grand debut at the 2025 International Digital Energy Expo, where it attracted a great deal of attention.
