my country's first ton-level hydrogen liquefaction system was successfully developed

According to CCTV news, recently, China's first independently developed hydrogen liquefaction system with a production capacity of ton level was successfully commissioned, and continuous and stable production has been achieved

During the system commissioning process, China's independently developed hydrogen liquefaction system successfully completed the start-up, production and automatic shutdown and rewarming procedures as planned.

According to Wang Chenggang, director of 101 Institute of the Sixth Academy of Aerospace Science and Technology Group, this system solves a series of key technologies such as turbo expanders, compressors, positive energy converters, and control systems, and has achieved more than 90% localization

At present, China's Long March 5, Long March 7 and other new-generation launch vehicle engines use liquid hydrogen and liquid oxygen as fuel

Prior to this, most of the liquid hydrogen used in China's aerospace field was produced by foreign equipment
