Italy has introduced the world’s first hydrogen train. Leading rail manufacturer Stadler and Italian transport company ARST have jointly unveiled a narrow-gauge hydrogen train, combining environmental sustainability with cutting-edge technology. This marks a historic milestone in the global railway sector. These eco-friendly trains are set to usher in a new era for Italy’s regional transport system.
The hydrogen trains are expected to be operational in Italy by 2028. There are specific reasons behind their introduction. The Sardinia region of Italy is characterized by large mountains and winding curves in every direction, making it virtually impossible to lay electric lines or run electric trains there. To address this challenge, Stadler and ARST designed a narrow-gauge hydrogen train using lightweight materials capable of handling low axle loads.
These trains will run between Alghero Airport and Mamuntanas, as well as between Sassari and Alghero, and Sassari and Sorso — all without any overhead electric lines. The propulsion system, fuel cells, and hydrogen tanks are housed in a central car, allowing it to function like a power pack battery charger, converting hydrogen into electrical energy to easily recharge the train’s batteries.
Around 10 such trains have been introduced in Sardinia. Experts say this initiative could prevent approximately 2,100 tonnes of carbon dioxide emissions annually. Since only water vapor is released into the atmosphere, there is no environmental risk whatsoever. Notably, the hydrogen used to power these trains is produced entirely through solar energy.
