At the Rail Live conference, the FCH2Rail consortium reported on successful dynamic tests of a hydrogen train. Tests of the new hydrogen train evaluated its performance and potential for real-world railway applications.

The tests aimed to assess the train’s power system and battery reliability under operational loads. Over six months, the train covered 10,000 kilometers in hydrogen mode. The systems operated efficiently, and the power supply management functioned without issues.

Spain’s railway network, known for extensive non-electrified sections and challenging terrain, served as the testing ground. In these conditions, the train traveled 804 kilometers without refueling, proving hydrogen’s viability. These results underline hydrogen’s potential in demanding environments, particularly mountainous regions.

However, ensuring the train’s hydrogen supply became a significant challenge as fueling stations were transported by road. This issue highlighted the urgent need for permanent hydrogen infrastructure and improved logistics.

The project received €14 million in funding, €10 million of which came from the European Commission. Valerie Bouillon-Delporte, director of the Clean Hydrogen Partnership, stressed the importance of reducing storage and transportation costs. She emphasized that without compelling economic arguments, transitioning from diesel to hydrogen traction will face hurdles.

The FCH2Rail hydrogen train is based on a three-car Civia model manufactured by CAF. It features two 80 kW hydrogen fuel modules from Toyota and CAF-supplied batteries enabling a 70-kilometer range. The train’s maximum speed is 140 kilometers per hour, demonstrating a balance of power and efficiency.

The German Aerospace Center coordinates the project, overseeing the FCH2Rail consortium. Members include CAF, Renfe, Toyota Motor Europe, Adif, Infraestruturas de Portugal, and others. Experts see the project as a promising step for integrating hydrogen technology into rail transport, despite existing challenges.

Further tests and technological advancements will determine hydrogen traction’s ability to replace diesel engines. Developing economically viable solutions remains the key challenge for the future of hydrogen trains.
