Ferrovie del Sud Est, the transport operator of the Puglia region, awarded Alstom a contract for the supply of two Coradia Stream H hydrogen trains to replace the current diesel trains. These will be the region’s first hydrogen trains.
Additionally, Ferrovie Nord Milano signed the second order for two Coradia Stream H hydrogen trains in addition to the six trains already on order, within the existing framework agreement, which allows for the acquisition of a total of 14 trains. In October 2023, Ferrovie Nord Milano and Alstom unveiled Italy’s first hydrogen train at EXPO Ferroviaria.
The new Coradia Stream H trains are based on Alstom’s single-deck Coradia Stream regional train platform. Specifically designed for the European market, these trains are manufactured by Alstom in Italy.
When using green hydrogen, the Coradia Stream H produces no direct CO2 emissions in operation, and just like the electric variant of the train, it offers the exceptional comfort appreciated by passengers. The train features several additional innovations in clean energy conversion, efficient energy supply and storage system combined with intelligent energy management. Alstom was the first railway actor to invest in hydrogen trains as an alternative to diesel traction for non-electrified lines.
The primary source of energy resides within the intermediate railcar known as the “power car”, where the core of hydrogen technology is situated. The energy is generated through the combination of hydrogen, stored in tanks, with oxygen from the external air, producing energy without emitting CO2 into the atmosphere. The energy is stored in high-performance lithium-ion batteries, which are utilised during acceleration to complement the hydrogen cells, optimising fuel usage. As part of the IPCEI Hy2Tech programme, the project is being funded by European Union – NextGenerationEU.
The train is designed and produced at Alstom’s plants in Italy, involving the Savigliano site for development, certification, production and testing, the Vado Ligure site for the outfitting of the “power car” in which the technologically innovative hydrogen-related part is installed, the Sesto San Giovanni site for components and the Bologna site for the development of the signalling system.
