Convert the chemical energy from the reaction of hydrogen and oxygen directly into electrical energy? This futuristic-sounding cutting-edge technology has become the "present tense" in the automated terminal of Qingdao port, Shandong port. The terminal adopts the world's first hydrogen-powered automatic rail crane to provide power for the automatic rail crane with a self-developed hydrogen fuel cell stack, effectively reducing the power consumption of each box of rail crane and reducing carbon dioxide emissions. "Hydrogen" is put into operation to make the port more green.
