ARST, the regional transport company in Sardinia, Italy, has recently granted a contract for the supply of the first six hydrogen trains. The move marks a significant stride in the energy transition journey undertaken by the Region of Sardinia and implemented by ARST.

The aim is to progressively ‘decarbonize’ local public transport on the island in alignment with environmental goals set at both European and national levels.

These trains will enhance connectivity in Sardinia, linking Alghero and Sassari/Sorso and the Alghero-Fertilia “Riviera del Corallo” airport.

In Alghero, the transition to more environmentally friendly transportation has already begun with the introduction of the first four electric buses. By 2024, this will be followed by further acquisitions, aiming to replace the entire bus fleet with green alternatives.

The next phase of this transformative process is the introduction of hydrogen trains, financed by non-repayable European funds to the tune of around €78 million. Surplus resources from previous funding will be directed toward the construction of an environmentally friendly hydrogen production plant and the building of a new railway section. This 7-kilometer segment, named Mamuntanas-Aeroport, is already under contract and will be awarded soon.

Swiss train manufacturer Stadler is set to supply the new hydrogen trains. These 50-meter-long units, due for delivery by December 2026, will be capable of speeds up to 100 km/h, accommodating up to 170 passengers. This is a significant stride toward a more sustainable and environmentally friendly transport system in Sardinia.

Hydrogen-powered trains represent a key aspect of green transport solutions. Emitting only water, these trains are a viable and clean alternative to diesel, contributing significantly to the reduction of carbon emissions.

This initiative underlines Sardinia’s commitment to the decarbonization of public transport, making a powerful statement on the region’s environmental responsibility. As countries around the world grapple with the urgent need to reduce carbon emissions, Sardinia’s efforts provide a promising blueprint for sustainable, hydrogen-based public transportation systems.
