On May 10, CRRC released its latest green and low-carbon technology achievements - the world's first hydrogen energy city train at the 2023 China Brand Day event.
The world's first hydrogen city train is a four-car train with a maximum speed of 160 kilometers per hour. The built-in "hydrogen power" system adopts the energy supply mode combining hydrogen fuel cells and supercapacitors, which can achieve an ultra-long range of 600 kilometers. Because it replaces the original catenary power supply scheme, the energy is generated by the electrochemical reaction of hydrogen and oxygen in the hydrogen fuel cell, and the reaction process is stable, the noise is small, and the reaction product is only water, so it has the characteristics of environmental protection and zero carbon.
At the same time, the vehicle-vehicle communication system is adopted to optimize the vehicle control process and greatly improve the train operation efficiency and safety and reliability. The train is equipped with multiple intelligent detection systems and thousands of intelligent sensors, just like a doctor on board, which can conduct self-examination and self-perception at any time, and automatically monitor, diagnose and protect the hydrogen storage system and hydrogen fuel cell system to ensure the safety and reliability of the hydrogen system during driving. In addition, the train adopts 5G large-capacity train-to-ground communication technology to realize the multi-network integration of train-to-ground information transmission, and evaluates the operation status of the train through big data analysis technology to ensure driving safety.
