CRRC Unveils World's First Low-Temperature-Resistant Automatic Hydrogen Refueling Robot

TapTechNews May 21, it was announced by CRRC that the world's first low-temperature-resistant automatic hydrogen refueling robot jointly developed by CRRC Sifang Institute under the group and the Hydrogen Energy Technology Company of National Energy Group has completed the full-system commissioning and achieved automated hydrogen refueling for terminal hydrogen use.

According to the introduction, the hydrogen refueling robot is mainly composed of a safety room, a robot, and supporting safety sensors, etc. Through the coordinated cooperation of multiple modules, it can realize one-click automated hydrogen refueling for hydrogen-powered locomotives, becoming a new productive force in the field of hydrogen refueling and railway freight transportation, and also providing important support for the construction of hydrogen refueling stations on the Mengxi heavy-haul railway.

The official said that the robot system has obtained the first domestic explosion-proof qualification certificate for hydrogen refueling robots in China, meeting the hydrogen explosion-proof requirements of IIC level, with functions of fault self-diagnosis and fault alarm, being able to monitor the running environment of vehicles and itself in real time, and the implementation of security operations is more reliable, stable, and safe.

TapTechNews learned from the official that the robot can conduct large-flow hydrogen refueling operations continuously for 7×24 hours at a low temperature of minus 25 degrees Celsius (about minus 13 degrees Fahrenheit), and the maximum hydrogen refueling flow rate reaches 7.2 kilograms/minute, reaching the international leading level.
