India has taken a major step towards cleaner transportation with the successful rollout of its first hydrogen-powered train. The project marks the country's entry into hydrogen-based rail mobility and demonstrates how alternative fuels could play an important role in reducing carbon emissions across selected railway routes.
While the pilot has generated significant interest, experts believe that expanding hydrogen-powered trains across India's vast railway network will require far more than introducing new locomotives. The biggest challenge lies in building an entire hydrogen ecosystem, including production, storage, transportation, refuelling infrastructure and safety systems.
The first hydrogen-powered train is operating on the 89-kilometre Jind-Sonipat route under Northern Railway. Running as part of the "Hydrogen for Heritage" initiative, the train showcases India's ambition to use green hydrogen for sustainable mobility, particularly on routes where conventional electrification is difficult or economically unviable.
Unlike diesel trains that burn fossil fuels or electric trains that draw power from overhead lines, hydrogen-powered trains generate electricity through fuel cells. Hydrogen stored in onboard tanks reacts with oxygen inside the fuel cell to produce electricity, with water vapour being the only direct emission. This makes the technology an environmentally friendly option for low-density railway routes.
However, railway experts point out that operating one hydrogen train is very different from deploying hundreds across the country. Every hydrogen corridor would require dedicated production facilities or reliable hydrogen supply chains, compression plants, storage systems, dispensing stations and trained personnel capable of handling the technology safely.
Industry specialists say the real challenge is integrating every component of the hydrogen value chain rather than focusing solely on the train itself. Without proper infrastructure, large-scale deployment will remain difficult despite technological success.
Another important consideration is India's already extensive railway electrification. Nearly the entire broad-gauge railway network has been electrified, making electric locomotives the most efficient and cost-effective solution for most routes. Experts therefore believe hydrogen trains are unlikely to replace electric trains. Instead, they are expected to complement existing infrastructure by serving heritage railways, remote regions, mountainous terrain, border areas and other locations where overhead electrification is impractical.
Cost remains another major hurdle. Green hydrogen continues to be significantly more expensive than conventional fuels. Besides production expenses, railway authorities must also account for compression, storage, transportation and refuelling costs before the technology becomes commercially competitive.
Researchers across India are working on advanced hydrogen production techniques aimed at reducing costs over the coming years. Improvements in electrolysis technologies, advanced catalysts, wastewater-based hydrogen production and safer storage methods are expected to make hydrogen more affordable for transport applications.
Experts also stress that hydrogen infrastructure should be developed route by route rather than station by station. Integrated hydrogen hubs combining renewable energy generation, electrolysers, storage systems and refuelling stations would improve efficiency while reducing operating costs.
The environmental benefits of hydrogen trains also depend on how the hydrogen itself is produced. Green hydrogen is considered truly sustainable only when renewable energy powers the electrolysis process. If hydrogen production relies on conventional electricity generated from fossil fuels, much of its environmental advantage is lost.
India's National Green Hydrogen Mission aims to significantly increase domestic green hydrogen production over the coming years. Although railway demand will represent only a portion of total hydrogen consumption, coordinated expansion of renewable energy capacity and hydrogen infrastructure will be essential for long-term success.
Railway experts expect hydrogen-powered trains to be introduced gradually rather than rapidly. Future expansion is likely to focus on selected heritage lines, hilly regions and low-density passenger corridors before any large-scale deployment takes place after 2030.
Beyond railways, the technology could eventually support cleaner transportation across trucks, ships, aviation and heavy industries, contributing to India's broader transition towards low-carbon energy systems.
