Hydrogen End Use – Trains
Hydrogen is gaining attention as a clean and sustainable alternative in the rail industry, particularly for trains. Here are key aspects of how hydrogen is being used in rail:
Hydrogen Fuel Cell Trains
- Power Source: Hydrogen fuel cell trains use hydrogen gas to generate electricity through fuel cells on board the train. This electricity then powers electric traction motors, propelling the train.
- Zero Emissions: The primary advantage is the elimination of direct emissions of greenhouse gases and pollutants. Hydrogen fuel cell trains produce only water vapor and heat as by-products, making them environmentally friendly.
- Range and Refueling: Hydrogen trains offer a comparable range to traditional diesel trains. The refueling process is relatively quick, taking around 15-20 minutes, making it suitable for efficient and regular operations.
- Existing Infrastructure: Hydrogen trains can often use existing rail infrastructure designed for diesel trains, minimizing the need for extensive modifications.
Examples & Deployment
- Alstom Coradia iLint: The Alstom Coradia iLint is one of the first hydrogen fuel cell trains to enter commercial service. It operates in Germany and has demonstrated the feasibility of hydrogen-powered trains in regular passenger service.
- UK Trials: The UK has initiated trials and pilot projects to explore the feasibility of hydrogen trains. Companies like Porterbrook and various rail operators are involved in testing and deploying hydrogen-powered trains.
Challenges & Considerations
- Infrastructure: Establishing a hydrogen infrastructure for refueling remains a challenge, as it requires dedicated hydrogen production and distribution facilities.
- Costs: While the cost of hydrogen fuel cell technology is decreasing, initial infrastructure investments and the cost of hydrogen production can be significant barriers.
- Energy Efficiency: The efficiency of converting electricity to hydrogen, transporting and storing hydrogen, and then converting it back to electricity in fuel cells must be optimized to enhance overall energy efficiency.
The use of hydrogen in rail represents a promising avenue for reducing the environmental impact of transportation. As technology advances and infrastructure develops, hydrogen fuel cell trains have the potential to play a substantial role in decarbonizing the rail industry, contributing to more sustainable and eco-friendly rail travel.

October 2023: California’s commitment to clean transportation reaches a milestone as Caltrans signs an $80 million contract with Stadler Rail, Inc. to introduce North America’s first hydrogen-powered intercity passenger trains. These trains, based on Stadler’s FLIRT concept, will utilize zero-emission hydrogen fuel cells, eliminating the need for a separate locomotive. The purchase is part of Governor Gavin Newsom’s $10 billion zero-emission vehicle package, with $407 million allocated to CalSTA for cutting-edge clean bus and rail equipment. The hydrogen trainsets aim to showcase emerging technology and will operate primarily between Merced and Sacramento, connecting with expanded rail services. The contract includes options for up to 25 additional trainsets, emphasizing California’s commitment to sustainable and innovative transportation solutions.
