India’s First Hydrogen-Powered Train
Subject: Science & Technology
Why is this in News?
On 17 July 2026, Prime Minister Narendra Modi flagged off India’s first hydrogen-powered train on the 89-km Jind–Sonipat route in Haryana.
- 10 coaches
- Passenger capacity: ~2,600
- Powered entirely by Green Hydrogen Fuel Cell Technology
How Does a Hydrogen-Powered Train Work?
Unlike conventional electric trains, the hydrogen train generates electricity onboard instead of drawing power from overhead electric lines.
Working Mechanism
Step 1: Hydrogen Storage
- Green hydrogen is stored in high-pressure cylinders inside the train.
Step 2: Fuel Cell Reaction
Inside the Proton Exchange Membrane (PEM) Fuel Cell:
- Hydrogen (H₂) reacts with Oxygen (O₂) from the atmosphere.
- An electrochemical reaction produces:
- Electricity
- Water Vapour
- Heat
Step 3: Electricity Generation
- Electricity powers the traction motors that drive the train.
- Excess electricity is stored in Lithium Iron Phosphate (LiFePO₄) batteries.
Step 4: Clean Emission
The only by-products are:
- Water Vapour
- Heat

What is a Proton Exchange Membrane (PEM) Fuel Cell?
A PEM Fuel Cell converts the chemical energy of hydrogen directly into electricity through an electrochemical reaction without combustion.
Advantages
- High efficiency
- Zero carbon emissions at the point of use
- Quick start-up
- Low noise
- Suitable for transport applications
Train Configuration
The train consists of:
- 2 Hydrogen Driving Power Cars (DPCs)
- 8 Trailer Coaches
Each Driving Power Car contains:
- Proton Exchange Membrane (PEM) Fuel Cells
- Lithium Iron Phosphate (LiFePO₄) Batteries
- Hydrogen Storage Cylinders
Power Output
- 1,200 kW per Power Car
- Total Power: 2,400 kW
Maximum Speed
- 110 km/h
How is Hydrogen Produced?
Hydrogen is produced at the Jind Green Hydrogen Plant through Electrolysis.
Electrolysis
Electricity splits water into:
- Hydrogen (H₂)
- Oxygen (O₂)
Hydrogen is then:
- Stored in dedicated tanks
- Compressed to 500 bar
- Dispensed to trains at 350 bar
Storage Capacity
- Approximately 3,000 kg of hydrogen
- Sufficient for regular train operations
Safety Measures
Although hydrogen is highly flammable, it is:
- Colourless
- Odourless
- Tasteless
- Non-toxic
Safety Systems Installed
- Hydrogen Leak Detectors
- Flame Detectors
- Smoke Sensors
- Heat Sensors
- Continuous Ventilation
- Automatic Hydrogen Shut-off System
- Water Spray Fire Suppression System
The complete system was independently certified by TÜV SÜD (Germany).
The hydrogen storage and dispensing infrastructure has been approved by the Petroleum and Explosives Safety Organisation (PESO).
Environmental Benefits
Hydrogen-powered trains:
- Produce Zero Tailpipe Carbon Emissions
- Reduce dependence on fossil fuels
- Improve air quality
- Lower greenhouse gas emissions
- Reduce noise pollution
- Support sustainable rail transport
Global Scenario
Hydrogen-powered passenger trains are still in the early stages of deployment.
Countries Working on Hydrogen Rail
- Germany (First commercial deployment)
- France
- Italy
- China
- Japan
India’s Future Plans
Indian Railways plans to introduce hydrogen-powered trains on:
- Heritage Railway Routes
- Kalka–Shimla Railway
The initiative supports:
- National Green Hydrogen Mission
- India’s Net Zero Target (2070)
- Decarbonisation of the transport sector
Challenges
- High production cost of green hydrogen
- Limited hydrogen refuelling infrastructure
- Safe storage and transportation of hydrogen
- High initial capital investment
- Need for large-scale renewable energy for hydrogen production
Way Forward
- Expand green hydrogen production using renewable energy.
- Develop nationwide hydrogen refuelling infrastructure.
- Promote indigenous fuel cell manufacturing under Make in India.
- Increase deployment on non-electrified and heritage railway routes.
- Integrate hydrogen technology with India’s long-term clean energy strategy.
