In a groundbreaking move, Valcamonica, an Alpine region in northern Italy, is set to introduce hydrogen-powered trains next year. This initiative, backed by a substantial investment of 367 million euros, signifies a remarkable shift towards sustainable transportation. The project, the first of its kind in Italy, involves replacing 14 diesel trains with zero-emission hydrogen-powered trains manufactured by Alstom. This transition aligns with the European Union's strategy for energy transition, emphasizing the use of green hydrogen derived from water electrolysis using renewable sources. While acknowledging the high costs involved, particularly in comparison to electric trains, project chairman Andrea Gibelli highlights the necessity of hydrogen for the mountainous region of Valcamonica. By directly addressing the supply challenge associated with hydrogen through on-site electrolysers, the project ensures the production of green hydrogen using electricity from renewable sources. Despite the higher price of hydrogen, around 10-15 euros per kilogram, the project focuses on the long-term benefits of reducing ecological impact and avoiding the costs and infrastructure changes required for electrification. Funding for this innovative project comes from the regional government and the EU's Recovery and Resilience Plan, guaranteeing that travellers will not experience fare increases. This initiative not only promotes sustainable transportation but also marks a significant step in embracing green technology and renewable energy in the region, setting a positive example for future energy transitions.
