Sichuan Chuannan Rail Transit Operation Co Ltd, based in Yibin, China, is taking a significant step towards sustainable urban transport by introducing hydrogen-powered ART vehicles alongside their battery-electric fleet. This decision was partly influenced by the Kuching Urban Transportation System project in Sarawak, Malaysia. With a current ridership of 50,000 per day, Yibin's ART fleet is set to expand with the addition of five hydrogen-powered vehicles, emphasizing the global potential of hydrogen in public transportation. In addition to Yibin, the city of Lingang in China and Daejeon in South Korea are also embracing hydrogen technology in their public transport systems. Shanghai's Lingang New Area Public Transportation Co Ltd operates three lines with 23 hydrogen-powered Digital Rapid Transit vehicles. Moreover, Hyundai's commitment to providing 1,000 hydrogen buses by 2027 further underlines the growing adoption of hydrogen in the transportation sector. Mazli Mustaffa, the CEO of Sarawak Metro, expressed confidence in Sarawak's ability to produce green hydrogen locally, leveraging the region's abundant natural resources.

The company aims to lead in decarbonizing the public transport sector while providing safe and reliable services. The article highlights the evolving landscape of hydrogen technology in public transportation globally, emphasizing the commitment towards sustainable energy solutions.
