The Prime Minister flagged off India's first hydrogen-powered train named NaMo Green Rail.
The train completed its maiden run on the 89-km Jind-Sonipat section in Haryana.
This technology demonstration project validates hydrogen propulsion, refuelling systems, and operating procedures for future rail operations.

The Research Designs and Standards Organisation (RDSO) prepared the technical specifications, while M/s Medha Servo Drives engineered and integrated the system.
The 10-coach trainset features two Hydrogen Driving Power Cars and eight Trailer Coaches.
Each power car generates 1,200 kW, giving the train a total propulsion capacity of 2,400 kW.
The train operates at a service speed of 75 kmph with a maximum design speed of 110 kmph.
The energy storage system pairs fuel cells with Lithium Iron Phosphate (LFP) batteries to manage acceleration and fluctuating track loads.

The train carries an onboard Proton Exchange Membrane (PEM) fuel cell that acts as a clean electricity generator.
At the anode, a specialized catalyst splits stored hydrogen gas into protons and electrons.
A polymer membrane allows positively charged protons to cross to the cathode while blocking electrons.
Blocked electrons flow through an external electrical circuit, generating electricity to run the traction motors.
At the cathode, protons and electrons recombine with atmospheric oxygen to release harmless water vapour and heat.

Onboard cylinders store hydrogen refuled at 350 bar pressure from a 500-bar compression facility located in Jind.
Automated sensors continuously track gas leaks, flames, and heat to trigger an immediate emergency shut-off without manual input.
Active canopy ventilation loops continuously dilute any escaping hydrogen gas and vent it safely into the open atmosphere.
The storage system earned approval from the Petroleum and Explosives Safety Organisation (PESO) and received independent validation from TÜV SÜD, Germany.

The fuel cell reaction produces zero smoke or carbon tailpipe emissions, offering a eco-friendly alternative to fossil fuels.
With this deployment, India joins advanced nations like Germany, Japan, China, and the United States in operating hydrogen rail technology.
The initiative aligns with the National Green Hydrogen Mission and accelerates India's progress toward Net Zero targets.
Deploying hydrogen trains creates reliable demand for green hydrogen and stimulates investments in clean energy infrastructure.

Producing green hydrogen remains significantly more expensive than procuring traditional diesel fuel.
High-pressure storage and specialized transport requirements demand capital-intensive infrastructure.
The limited availability of green hydrogen across the country restricts rapid large-scale adoption.

Hydrogen trains can replace diesel engines on non-electrified routes, heritage tracks, and difficult terrains like the Kalka-Shimla line.
Scaling up domestic green hydrogen production will lower fuel costs and ensure steady supply for transport applications.
Setting up specialized refuelling hubs along major railway corridors will enable broader deployment across the national train network.
