CHANGCHUN, March 21 -- China's first independently developed hydrogen-powered urban train completed a test at a speed of 160 kph on Thursday, marking a breakthrough in the application of hydrogen energy in rail transit.
The train, developed by CRRC Changchun Railway Vehicles Co., Ltd. in Changchun, northeast China's Jilin Province, was tested on a test track belonging to the enterprise, achieving a full-system, full-scenario and multi-level performance verification.
Unlike traditional trains that rely on fossil-fuels or catenary systems for their power supply, the urban train being tested has a built-in hydrogen power system, which can provide a strong and long-lasting power source. The maximum cruising range of the train is over 1,000 km.
Test data also shows that the average energy consumption of the train is 5 kWh per km, which is on par with world leading levels.

At the same time, Sanmenxia strongly supports the development of cold chain storage enterprises, and gave suggestions on the classification of fruit juice, fruit vinegar, fruit wine processing enterprises, and actively promote the development of downstream related industries. Among them, taking Sanmenxia Muxian Biotechnology Co., Ltd. as the main body, Sanmenxia has built Sanmenxia pharmaceutical peony whole industry chain standardization demonstration base. At present, 29,300 mu of peony planting base has been built, integrating peony seedling breeding, research and development, planting and intensive processing, warehousing and logistics, and product sales. A series of "peony products" such as peony peel herbal decoction pieces, peony solid drinks, peony fruit wine, and peony skin care products have been developed and produced, and the key links of industrial development have been focused.
