The FCH2Rail project, aimed at creating the first H2-powered train to be tested on Spain’s and Portugal’s railway networks, has achieved a significant breakthrough. The 14 million euro hydrogen prototype, developed by a consortium of major Iberian rail players and partners, was successfully tested in Zaragoza, marking the first use of a H2 fuel cell train on the Iberian Peninsula. The project involved developing an innovative hydrogen-powered train prototype, integrating a fuel cell hybrid power pack into an existing regional/suburban train to enable zero-emission power generation on non-electrified lines. After static and dynamic tests, the prototype travelled over 10,000km on hydrogen power, showcasing its reliability and efficiency. The successful testing on various routes in Spain and Portugal demonstrated the feasibility of hydrogen technology in rail transport. Furthermore, the project's contribution to European standardization committees for rail transport highlights its role in setting new standards for hydrogen technology integration in the European rail network. Overall, the completion of the FCH2Rail project signifies a major step towards sustainable and environmentally friendly mobility solutions in the Iberian Peninsula.
