“Hydrogen energy, as a green energy source, is of great significance for achieving China's goals of "carbon peak" and "carbon neutrality". The mixed refrigerant hydrogen liquefaction process is an effective means to solve the bottleneck of hydrogen energy storage and transportation technology. Experts have conducted statistical analysis on the mixed refrigerant hydrogen liquefaction process and proposed development suggestions to provide effective support for efficient large-scale storage and transportation technology of hydrogen energy, accelerating the large-scale commercialization of hydrogen energy.”
