The project, which began in January 2021, was led by a consortium including CAF, DLR, Toyota, Renfe, Adif, CNH2, IP, and Stemmann-Technik, with 70% of the funding provided by European resources.
Over the past four years, FCH2Rail partners have developed a bi-mode demonstrator train equipped with the innovative fuel cell hybrid powerpack. The system allows trains to operate on both electrified lines using overhead power and non-electrified lines powered by hydrogen fuel cells and LTO batteries.
The event featured a presentation on the project’s development and achievements, followed by a panel discussion involving leaders from Renfe, CAF, Adif, and CNH2. Attendees, including Valerie Bouillon-Delporte of the Clean Hydrogen Partnership, toured the hydrogen-powered train and took a live demonstration ride between CAF’s Zaragoza plant and Villanueva de Gállego station.
The prototype train, adapted from an existing Renfe commuter model, underwent rigorous testing at every stage. The first phase involved designing and integrating the hybrid power system with the train’s traction system, followed by static tests at CAF’s Zaragoza plant in 2022. These initial tests validated the system's safety, efficiency, and hydrogen refueling capability.
Dynamic testing commenced mid-2022, initially on closed tracks and later on Spain's national rail network. The train’s capabilities were assessed under various power demand conditions, including the challenging Zaragoza-Canfranc route in the Pyrenees, known for its steep gradients.
Over the course of testing, the train traveled more than 10,000 kilometers in hydrogen mode across regions like Aragon, Madrid, and Galicia. A significant milestone was achieved when the train crossed into Portugal for additional testing, further demonstrating its versatility and competitiveness as a sustainable alternative to diesel traction.
In addition to technical achievements, the FCH2Rail consortium actively contributed to European standardisation committees, advocating for new guidelines to support hydrogen and fuel cell technology in rail networks.
The success of the FCH2Rail project highlights the growing interest from public and private stakeholders in sustainable rail solutions. As the rail industry moves toward decarbonisation, hydrogen-powered trains are emerging as a promising alternative to diesel, with the potential to transform rail transport across Europe and beyond.
