Hydrogen Trains for Sardinia
On June 23 at 7:00 PM, it was announced that new SRHe 113 class trainsets will begin passenger service on the Italian island of Sardinia starting in 2028. Specifically, the hydrogen-powered trains will operate on the Sassari–Alghero and Sassari–Sorzo routes. Replacing diesel trains with ten hydrogen units will cut carbon dioxide emissions by more than 2,100 tons each year.
Technology and Environmental Initiatives
The propulsion system of the new trains relies on fuel cells and hydrogen tanks. The hydrogen needed for their operation will be produced entirely using solar energy. Operator ARST plans to transform itself into an energy company, reflecting a strategic shift toward green technologies.
Narrow-gauge railways, where the new trains will run, require very low axle loads. To meet this demand, the carriages are built from ultra-light materials with a special profile. The train interiors feature air conditioning, large panoramic windows, and a low-floor design, ensuring a comfortable ride for passengers.
The project is part of Italy's government-led transport decarbonization program. Similar innovative solutions, developed by Stadler, are also planned for implementation in Calabria and Sicily. In this way, Italy is advancing the eco-friendly modernization of its transport infrastructure, cutting emissions and shifting to renewable energy sources.
The introduction of hydrogen trains on Sardinia marks a significant step toward improving the environmental sustainability of Italy's transport system. Reducing carbon dioxide emissions and utilizing renewable energy not only lessens the negative impact on the environment but also demonstrates the country's commitment to meeting international environmental standards. Such initiatives can serve as a model for other regions and countries in adopting green technologies in the transport sector.
