On May 22, 2026, the Railway Board of India signed the circular authorizing the operation of the country's first hydrogen fuel cell-powered train. The train will run on the Jind–Sonipat route in Haryana, and its only emission is water vapor.
With this approval, India formally joins a select group of nations that already operate or are testing hydrogen-powered rail systems, alongside Germany, Japan, China, and the United States.
But what makes this project technically relevant goes beyond the train itself.
What exactly is this train?
The train was developed by the Integral Coach Factory (ICF), a manufacturing unit in Chennai linked to the Ministry of Railways. The solution adopted was a retrofit: hydrogen fuel cells were integrated into an existing DEMU (Diesel Electric Multiple Unit), replacing the diesel engines.
Main specifications:
- Propulsion: 1,200 kW hydrogen fuel cell system
- Maximum speed: 75 km/h
- Configuration: 10 wagons (2 traction cars + 8 passenger cars)
- Emission: only water vapor
- Capacity: up to 2,600 passengers
The reaction that powers the train is electrochemical: hydrogen combines with oxygen from the air, generating electricity and water. No combustion, no CO₂, no particulate matter.
The electrolyzer at the heart of the project
The supply comes from a green hydrogen production plant installed at the Jind station itself. The process is electrolysis, the same method used by industrial electrolyzers to separate hydrogen from oxygen present in water.
The infrastructure includes:
- Storage capacity of 3,000 kg of compressed hydrogen
- Dedicated 11 kV power supply for continuous plant operation.
- PESO regulatory license for the storage and dispensing of H₂
This detail is not peripheral. It is the central point of the model: without local hydrogen production, a fuel cell train depends on a distribution logistics system that does not yet exist on a large scale. The Indian decision to install the electrolyzer at the refueling point itself solves this bottleneck at its root.
What the European experience teaches us
Germany was a pioneer. In 2018, Alstom put the Coradia iLint into commercial operation in Lower Saxony, the world's first hydrogen-powered train to carry passengers. The model reached 140 km/h and covered 2.8 million kilometers before encountering fuel supply and fuel cell maintenance problems that led to the suspension of services in Hesse in 2025.
The lesson is straightforward: the technology works. The system around it is still maturing.
Other countries are following the same path, with different approaches:
- Bavaria (Germany): Siemens Mireo Plus H trains, scheduled for 2026, with local electrolysis in Mühldorf.
- Italy: €367 million project in Valcamonica with 14 Coradia units and on-site electrolyzers
- France: SNCF with 12 electro-hydrogen units in testing phase.
The pattern that emerges is always the same: train + local electrolyzer + certified hydrogen.
The size of the market that is forming.
The global market for hydrogen fuel cell trains is expected to grow from $2.67 billion in 2025 to $26.4 billion by 2035, a CAGR of 28.2%, the highest among all rail rolling stock segments.
The driving force is structural: more than 70% of the world's rail network is not electrified. In sections where conventional electrification is economically unfeasible, hydrogen competes directly with diesel, winning in terms of emissions, long-term operating costs, and regulation.
Each new approved route in the world also represents a new demand for decentralized hydrogen generation capacity.
What to expect from here on out
The Jind–Sonipat route is a pilot project. The Indian Ministry of Railways aims to demonstrate viability before scaling up to other non-electrified sections of the country, which total tens of thousands of kilometers. The retrofit model applied reduces the entry cost by reusing existing train sets, a significant advantage for emerging markets.
The Indian approval comes as the hydrogen train market transitions from the demonstration phase to the commercialization phase.
For players in the energy sector, this is not just railway news. It's a market signal.
