Sichuan Chuannan Rail Transit Operation Co Ltd, the largest operator of Autonomous Rapid Transit (ART) vehicles in Yibin, is planning to incorporate hydrogen-powered ART vehicles into its zero-emission fleet. This shift towards hydrogen was influenced by the Kuching Urban Transportation System (KUTS) project, reflecting a global trend towards decarbonisation in public transport. With a fleet of 60 ART vehicles serving 50,000 passengers daily, Sichuan Chuannan Rail Transit Operation aims to increase ridership by introducing hydrogen-powered vehicles. Meanwhile, Lingang in Shanghai operates hydrogen-powered Digital Rapid Transit (DRT) vehicles. Additionally, South Korea's Daejeon city is progressing with a hydrogen light rail project. Hyundai's commitment to supply 1,000 hydrogen buses by 2027 further highlights the global embrace of hydrogen technology. Sarawak Metro in Kuching sees an opportunity in green hydrogen production, aligning with its goal of sustainable transport. By leveraging local resources and advancing clean energy solutions, Sarawak Metro aims to lead in sustainable urban transport and contribute to climate action efforts on a regional scale.
