An aerial drone photo taken on April 14, 2025 shows hydrogen-powered heavy-duty trucks awaiting departure from the dry port of the New International Land-Sea Trade Corridor in Chongqing, southwest China. China's first cross-region hydrogen heavy-duty truck route was launched on Monday, marking a milestone in terms of advancing hydrogen energy development in China's western regions. The route, now operational for regular freight services via hydrogen-powered heavy-duty trucks, spans 1,150 kilometers from southwest China's Chongqing Municipality to Qinzhou Port in south China's Guangxi Zhuang Autonomous Region, passing through southwestern Guizhou Province.
