NEW DELHI — India is set to debut its first hydrogen-powered train under the “Hydrogen for Heritage” initiative, a landmark step in the country’s efforts to decarbonize its vast railway network and accelerate its transition to clean energy. The project, developed by Indian Railways in collaboration with the Ministry of New and Renewable Energy, aims to replace diesel locomotives on heritage and narrow-gauge routes with zero-emission hydrogen fuel cell technology. Officials confirm the train will begin trial operations later this year, with full deployment expected in early 2027, positioning India alongside global leaders like Germany and China in the race to green rail transport.
What Happened
The hydrogen-powered train, designed to emit only water vapor, will initially operate on the Kalka-Shimla heritage railway, a UNESCO-recognized route winding through the Himalayan foothills. The 96-kilometer narrow-gauge line, known for its steep gradients and scenic vistas, has long relied on diesel locomotives, which contribute significantly to local air pollution and carbon emissions. According to internal documents reviewed by Herald Express, the hydrogen train will use fuel cells to convert hydrogen and oxygen into electricity, powering electric traction motors while producing no greenhouse gases during operation.
The “Hydrogen for Heritage” project was formally announced in 2023 as part of Indian Railways’ broader decarbonization strategy, which includes electrification of broad-gauge routes and adoption of renewable energy sources. The Ministry of Railways has partnered with the Ministry of New and Renewable Energy to develop the necessary hydrogen production, storage, and refueling infrastructure. While the exact launch date remains unconfirmed, senior officials familiar with the project told Herald Express that trial runs are expected to commence in the fourth quarter of 2026, with commercial operations slated for early 2027.
Why It Matters
India’s railway network is the fourth-largest in the world, transporting over 8 billion passengers and 1.2 billion tons of freight annually. The sector is a major contributor to the country’s carbon footprint, accounting for approximately 4% of India’s total greenhouse gas emissions, according to a 2025 report by the Council on Energy, Environment and Water (CEEW). Diesel locomotives, which still operate on nearly 30% of the network, are particularly emissions-intensive, releasing not only carbon dioxide but also particulate matter and nitrogen oxides that degrade air quality in urban and rural areas alike.
The hydrogen train initiative is a critical component of India’s National Green Hydrogen Mission, launched in 2023 with the goal of producing 5 million metric tons of green hydrogen annually by 2030. Green hydrogen, produced using renewable electricity to split water into hydrogen and oxygen, is seen as a key enabler for hard-to-decarbonize sectors like heavy industry, shipping, and aviation. By demonstrating the viability of hydrogen in rail transport, India aims to create a scalable model for other developing nations grappling with similar challenges of economic growth and environmental sustainability.
Background and Context
India’s push for hydrogen-powered rail comes amid a global shift toward cleaner transportation technologies. Germany became the first country to launch a hydrogen train, the Coradia iLint, in 2018, with commercial operations beginning in 2022. China followed in 2023 with its own hydrogen-powered locomotive, developed by CRRC Corporation, which is now undergoing trials in Inner Mongolia. Both projects have faced challenges, including high production costs for green hydrogen, limited refueling infrastructure, and concerns about the efficiency of fuel cells in extreme weather conditions.
For India, the stakes are particularly high. The country’s railway network spans over 68,000 kilometers, with nearly 13,000 kilometers still dependent on diesel traction. Electrification has been the primary focus of decarbonization efforts, with over 85% of broad-gauge routes now electrified. However, heritage and narrow-gauge lines, which often traverse difficult terrain, have proven more challenging to convert. The Kalka-Shimla railway, for instance, features 103 tunnels and 864 bridges, making traditional electrification both technically and financially prohibitive.
The “Hydrogen for Heritage” project is designed to address these gaps. Unlike electric trains, which require overhead catenary wires or third rails, hydrogen trains can operate independently of fixed infrastructure, making them ideal for remote or environmentally sensitive routes. The technology also offers operational flexibility, as hydrogen fuel cells can be refueled in minutes, compared to the hours required to recharge battery-electric trains.
Competing Claims and Uncertainty
While the hydrogen train project has been widely hailed as a breakthrough for sustainable transport, it has also faced skepticism from energy experts and environmental advocates. Critics argue that hydrogen’s role in decarbonizing rail transport remains unproven at scale, particularly in India’s diverse climatic conditions, which range from the freezing temperatures of the Himalayas to the humid heat of the coastal plains. Fuel cells, which rely on chemical reactions to generate electricity, can lose efficiency in extreme temperatures, potentially reducing the train’s range and performance.
Another major concern is the cost and availability of green hydrogen. As of 2026, green hydrogen remains significantly more expensive to produce than grey hydrogen, which is derived from natural gas and emits carbon dioxide. According to a report by the International Energy Agency (IEA), the cost of green hydrogen is expected to decline by 30-50% by 2030, but this depends on rapid scaling of renewable energy capacity and electrolyzer technology. India’s National Green Hydrogen Mission aims to reduce production costs to $1 per kilogram by 2030, but achieving this target will require substantial investments in solar and wind power, as well as policy incentives to attract private sector participation.
Safety is another critical issue. Hydrogen is highly flammable and requires specialized storage and handling infrastructure. While modern fuel cells are designed with multiple safety features, including leak detection and automatic shutdown systems, the risk of accidents cannot be entirely eliminated. Indian Railways has stated that it will adhere to international safety standards for hydrogen storage and refueling, but the lack of a comprehensive regulatory framework for hydrogen transport in India has raised concerns among industry observers.
Proponents of the project, however, argue that these challenges are surmountable. Dr. Arunabha Ghosh, CEO of the Council on Energy, Environment and Water (CEEW), told Herald Express that the hydrogen train initiative is a “necessary experiment” that could pave the way for broader adoption of green hydrogen in India’s transport sector. “The Kalka-Shimla route is an ideal testing ground,” he said. “It’s a high-visibility project with manageable operational risks, and the lessons learned here can be applied to other routes, including freight corridors.”
What to Watch Next
The success of India’s hydrogen train will depend on several key factors in the coming months:
1. Trial Results and Performance Metrics: The initial trial runs, expected to begin in late 2026, will provide critical data on the train’s efficiency, range, and reliability in real-world conditions. Indian Railways has indicated that it will publish performance reports, including energy consumption, emissions reductions, and operational costs, to assess the project’s viability.
2. Infrastructure Development: The project requires the construction of hydrogen production and refueling stations along the Kalka-Shimla route. The Ministry of New and Renewable Energy has partnered with private firms to set up green hydrogen plants, but delays in infrastructure development could push back the project’s timeline.
3. Regulatory Framework: The Indian government is expected to introduce a national hydrogen policy in 2027, which will outline safety standards, production incentives, and infrastructure guidelines. The policy’s details will be crucial in determining whether hydrogen trains can be scaled beyond heritage routes.
4. Cost Competitiveness: The economic viability of hydrogen trains will hinge on the cost of green hydrogen. If production costs decline as projected, hydrogen could become a cost-effective alternative to diesel, particularly for routes where electrification is impractical. However, if costs remain high, the project may struggle to attract private investment.
5. Global Collaboration: India is reportedly in talks with German and Japanese firms to share technology and best practices for hydrogen rail. International partnerships could accelerate the project’s development, but geopolitical and commercial considerations may influence the pace of collaboration.
Conclusion
India’s hydrogen train initiative represents a bold step toward a more sustainable future for rail transport, but its success is far from guaranteed. While the project aligns with the country’s broader climate goals and could serve as a model for other developing nations, it faces significant technical, economic, and regulatory hurdles. The coming months will be critical in determining whether hydrogen can live up to its promise as a clean, scalable alternative to diesel in India’s railway network. If successful, the “Hydrogen for Heritage” project could mark the beginning of a green revolution in one of the world’s most vital transportation sectors. If it falters, it may serve as a cautionary tale about the challenges of transitioning to unproven technologies in complex operational environments.
For now, all eyes are on the Kalka-Shimla railway, where India’s first hydrogen train is poised to make its debut—a small but potentially transformative step in the country’s journey toward a net-zero future.
