In Chile, EFE Trenes de Chile, in collaboration with the Ministry of Transport and Telecommunications, the National Hydrogen Institute (INH2), and Hydrox, has signed a second agreement to implement hydrogen propulsion systems in electric trains. This initiative aims to advance sustainable mobility by promoting green hydrogen as a clean energy source for national rail transport. The agreement involves developing and testing a hydrogen-powered train prototype, utilizing a decommissioned UT model that operated in the Biotren service. By exploring the incorporation of hydrogen in rail transport, Chile is taking a significant step towards reducing CO2 emissions and promoting clean energy use. The project aligns with Chile's sustainability objectives, with a vision to achieve carbon neutrality by 2035. This strategic move not only focuses on environmental benefits but also emphasizes energy efficiency, lower operating costs, and preparation for future technological advancements. The partnership signifies a commitment to innovative and sustainable transportation solutions, marking a milestone in Chile's transition towards a more environmentally friendly rail transport model.
