The Seoul Metropolitan Government, in collaboration with the Ministry of Environment and the Ministry of Land, Infrastructure and Transport, is embarking on an ambitious plan to expand the city's hydrogen bus fleet significantly. The government aims to increase the current fleet of 1,185 units to 21,200 units by 2030, with a particular focus on wide-area bus routes. This initiative is part of the 'Second Metropolitan Area Transportation Basic Plan (2021-2040)', which targets distributing 25% of all metropolitan buses as hydrogen-powered by 2030. Hyundai Motor and Doosan Fuel Cell are key players in the production of hydrogen buses, with new models set to debut soon. Hydrogen buses are being promoted for their environmental benefits, offering longer mileage and shorter charging times compared to electric buses. This shift is crucial for reducing greenhouse gas emissions and improving air quality, especially in densely populated urban areas like Seoul. Government officials are actively encouraging transportation companies to adopt hydrogen buses, providing support and incentives to facilitate the transition. Efforts are underway to foster a hydrogen vehicle ecosystem and promote carbon neutrality. Officials are optimistic about the progress, with plans to introduce hydrogen buses on new wide-area bus routes and retire older vehicles. The government's focus on carbon neutrality and sustainable transportation aligns with global efforts to combat climate change. By expanding the use of hydrogen buses, Seoul aims to lead the way in green public transportation and contribute to a cleaner, more sustainable future for its residents and the environment.
