What is a Hydrogen Train? The Future of Sustainable Rail Transport

As the world moves toward more sustainable energy sources, the transportation sector is adopting innovative technologies to reduce its environmental impact. One such technology is the hydrogen train, which offers a clean and efficient alternative to traditional diesel-powered trains.

What is a hydrogen train?

A hydrogen train, also known as a hydrogen-powered train, hydrogen railway, or hydrogen-fueled train, is a type of rail vehicle that uses hydrogen as its primary source of energy. These trains are powered by fuel cells that convert hydrogen and oxygen into electricity, emitting only water vapor and heat as byproducts.

How do hydrogen trains work?

Fuel cells

The main component of a hydrogen train is the fuel cell, which generates electricity through an electrochemical reaction between hydrogen and oxygen. In this process, hydrogen is combined with oxygen in the fuel cell, producing electricity and water as waste products.

Electric power

The electricity generated by the fuel cell powers the train's electric motors, which in turn drive the train's wheels. This means that hydrogen trains are essentially electric trains, with the added benefit of using a clean, renewable energy source.

Energy storage

Some hydrogen trains also incorporate energy storage systems, such as batteries or supercapacitors, to store excess electricity generated by the fuel cells. This stored energy can be used during periods of high power demand, such as acceleration or hill climbing, to supplement the fuel cell's output.

Types of hydrogen trains

Passenger trains

Hydrogen-powered passenger trains are designed to carry passengers over short to medium distances, providing a clean and quiet mode of transport. They are particularly well-suited for regional or suburban services, where electrification of the rail network may be impractical or too expensive.

Freight trains

Hydrogen trains can also be used for freight transport, providing a more sustainable alternative to diesel-powered locomotives. Although the technology is still in its infancy, the potential for hydrogen-powered freight trains is significant, particularly for transporting goods over long distances.

Advantages of hydrogen trains

Environmental benefits

One of the main advantages of hydrogen trains is their environmental friendliness. Since the only byproducts of the fuel cell reaction are water and heat, hydrogen trains produce zero harmful emissions. This makes them an attractive option for reducing the transportation sector's carbon footprint and improving air quality.

Energy efficiency

Hydrogen trains are more energy-efficient than their diesel counterparts, as fuel cells can convert a higher percentage of the fuel's energy into usable electricity. This means that hydrogen trains can potentially consume less fuel and produce less waste than traditional diesel trains, leading to cost savings and reduced environmental impact.

Infrastructure compatibility

Hydrogen trains can be easily integrated into existing rail infrastructure with minimal modifications. They can run on both electrified and non-electrified tracks, making them a versatile option for regions with mixed rail networks. This flexibility allows for the gradual adoption of hydrogen trains without requiring significant upfront investment in new infrastructure.

Challenges and limitations

Hydrogen production and storage

While hydrogen trains are eco-friendly, the production and storage of hydrogen can be challenging. Currently, the majority of hydrogen is produced through natural gas reforming, which results in greenhouse gas emissions. However, hydrogen can also be produced through electrolysis using renewable energy sources, reducing its environmental impact.

Storing hydrogen safely and efficiently is another challenge, as it has a low energy density and must be stored at high pressures or low temperatures. This can lead to increased costs and complexity in the design and operation of hydrogen trains.

Initial investment and costs

The initial investment for hydrogen train technology can be high, as fuel cells and hydrogen storage systems are still relatively expensive. However, as the technology matures and economies of scale are achieved, these costs are expected to decrease, making hydrogen trains more financially viable in the long run.

Limited range

The range of hydrogen trains is currently limited by the capacity of their onboard hydrogen storage systems. While the range is sufficient for many regional and suburban services, it may not be adequate for long-distance routes without refueling stops. This limitation could be overcome by improving hydrogen storage technology or establishing a network of hydrogen refueling stations along train routes.

Real-world examples

Germany's Coradia iLint

The Coradia iLint, developed by Alstom, is the world's first hydrogen-powered passenger train. It has been in commercial operation in Germany since 2018, providing a clean and quiet alternative to diesel trains on non-electrified rail lines.

France's Alstom

Alstom, the French rail manufacturer, is also developing a range of hydrogen-powered trains for various markets. These trains are expected to be more energy-efficient and environmentally friendly than traditional diesel trains, with the potential to revolutionize rail transport.

UK's HydroFLEX

The HydroFLEX is a hydrogen-powered passenger train developed by the University of Birmingham and Porterbrook, a UK-based rolling stock company. The train successfully completed its first trial runs in 2020, demonstrating the feasibility of hydrogen-powered rail transport in the UK.

The future of hydrogen trains

As countries around the world look to reduce their carbon emissions and transition to more sustainable energy sources, hydrogen trains are poised to play a significant role in the future of rail transport. With ongoing advances in fuel cell technology, hydrogen production, and storage, hydrogen trains have the potential to become a widespread, eco-friendly alternative to diesel trains in the coming years.


Hydrogen trains represent a promising solution for cleaner, more sustainable rail transportation. By harnessing the power of hydrogen fuel cells, these trains offer significant environmental benefits and energy efficiency, while maintaining compatibility with existing rail infrastructure. Although challenges remain in terms of hydrogen production, storage, and initial costs, the future of hydrogen trains looks bright as the technology continues to evolve.
