Hydrogen Fuel Cell Trains Enter Commercial Service
Western Europe has reached a major sustainability milestone as hydrogen fuel cell trains officially entered commercial service this week. These innovative trains, powered entirely by hydrogen, produce zero harmful emissions - releasing only water vapor as a byproduct. The launch marks a significant step toward decarbonizing regional rail networks across the continent.
Clean Technology Revolution
The Coradia iLint trains, developed by Alstom, utilize hydrogen fuel cells that convert chemical energy into electricity through an electrochemical reaction. Each train carries hydrogen in roof-mounted tanks that power fuel cells generating electricity for traction motors. Excess energy is stored in lithium-ion batteries for acceleration support.
"This technology eliminates local emissions while maintaining performance comparable to diesel trains," explains Dr. Eva Schneider, transportation researcher at ETH Zurich. "A single hydrogen refueling provides up to 1,000 km of range with refueling taking under 20 minutes."
Initial Deployment and Expansion
Commercial operations began on June 18, 2025, with three regional routes now running hydrogen trains:
- Lower Saxony, Germany: 14 trains serving Cuxhaven-Bremervörde-Buxtehude line
- Lombardy, Italy: 6 trains operating on Brescia-Iseo-Edolo route
- Auvergne-Rhône-Alpes, France: 4 trains on Clermont-Ferrand routes
Infrastructure includes hydrogen refueling stations powered by on-site electrolysis using renewable energy. Alstom has secured additional contracts for 27 trains in Hesse (Germany) and 12 trains for four French regions, with deployment planned through 2027.
Environmental Impact
Each hydrogen train reduces annual CO2 emissions by approximately 1,000 tons compared to diesel equivalents. The switch supports EU climate goals targeting 55% emission reductions by 2030. "This is particularly impactful for non-electrified rural lines where overhead wiring isn't feasible," notes EU Transport Commissioner Sofia Ricci.
While current hydrogen production relies partly on natural gas, new solar-powered electrolysis plants under construction will supply fully green hydrogen by 2028. The European Commission has allocated €2.3 billion for hydrogen rail infrastructure development through 2030.
Future of Rail Transport
Other manufacturers are entering the market, with Siemens Mobility testing its Mireo Plus H trains in Bavaria. The Netherlands and UK plan pilot programs in 2026. Analysts project hydrogen trains will comprise 15% of Europe's regional fleet by 2035.
Challenges remain regarding production scalability and costs. Current hydrogen trains cost approximately 30% more than diesel alternatives, though prices are expected to decrease as adoption grows. "This launch proves zero-emission rail is commercially viable today," says Alstom CEO Henri Poupart-Lafarge. "We're witnessing the beginning of a new era in sustainable transportation."
