Frequently Asked Questions (FAQs)
1. Where is India’s first commercial hydrogen train pilot being conducted? The pilot will operate on the Jind-Sonipat section of the Northern Railway in Haryana.
2. What are the primary technical specifications of the Jind-Sonipat trainset? It is a 10-coach trainset powered by a 1200 kW hydrogen fuel cell propulsion system. It has a design speed of 110 km/h but is approved to operate at a maximum speed of 75 km/h for the pilot.
3. Which components of the hydrogen train are genuinely manufactured in India? India handles the systems-integration layer. This includes the construction of the railcar and coaches at ICF Chennai, the retrofitting of diesel-electric multiple-units, and the design of the control systems and traction wiring by firms like Medha Servo Drives.
4. What critical components of the hydrogen train are currently imported? The "energy-conversion core" is imported. This includes the fuel cell stacks (often from Ballard Power Systems in Canada), the perfluorosulfonic-acid membranes (Nafion family), catalysts (Platinum Group Metals), gas diffusion layers (carbon-fibre paper), and carbon-fibre-overwrapped storage tanks.
5. How does the energy density of hydrogen compare to diesel? Hydrogen is a high-energy fuel with an energy density of 120 MJ/kg, which is significantly higher than diesel’s 43 MJ/kg.
6. What is the "Hydrogen for Heritage" initiative? It is a plan by Indian Railways to launch 35 hydrogen trains on various heritage and hilly routes where traditional electrification is technically difficult or cost-prohibitive.
7. Why is the Jind facility significant to this project? Jind houses the country's largest railway hydrogen storage and refueling facility, capable of storing nearly 3,000 kg of hydrogen. It also features a dedicated green hydrogen plant to supply the fuel.
8. What happened to the hydrogen rail projects in Germany that serves as a cautionary tale for India? Germany’s Coradia iLint fleet experienced significant reliability issues. By August 2025, only four of 14 units were running due to fuel cell degradation, hydrogen supply instability, and software issues, leading the state to pivot toward battery-electric trains.
9. What are the specific safety features of India’s hydrogen train? The train includes hydrogen leak detectors, flame detectors, non-stop ventilation systems, and automatic supply cut-offs. The system was certified by an independent third party, TÜV SÜD, Germany.
10. How does the lifetime cost of a hydrogen train compare to a diesel train on the Kalka-Shimla route? According to CSTEP, while a hydrogen train has a higher capital cost (INR 41–50 crore vs. INR 27 crore for diesel), it offers a lower lifetime cost (INR 70–85 crore vs. INR 103.2 crore for diesel) over 30 years.
11. Why are battery-powered trains considered unviable for the heritage and shunting routes? While economically competitive, battery-powered trains currently exceed the weight and volume allowances for these specific locomotives. For example, on the Kalka-Shimla route, the battery alone would weigh 16 tonnes, far exceeding the 9.25-tonne limit for retrofitting.
12. Is the hydrogen used in the Jind-Sonipat pilot truly "green"? While the facility uses an electrolyser to split water, the sustainability depends on the electricity source. If drawn from a coal-heavy grid without a confirmed renewable energy mix, the "green" status is debatable.
13. What firms have signed MOUs to advance hydrogen technology in India? Adani has signed an MOU with Ballard for PEM manufacturing; Hyundai is building an HTWO research centre at IIT Madras; and BHEL has a tie-up with Horizon Fuel Cell Group for fuel cell locomotives.
14. What are the main challenges to scaling hydrogen rail in India? The primary challenges include an unstable global supply chain, high initial capital costs, lack of domestic manufacturing for fuel cell materials (membranes and catalysts), and the nascent stage of green hydrogen production.
15. What is the total estimated cost for the wider rollout of hydrogen trains? The plan aims to put 35 trains into service at a cost of approximately Rs 2,800 crore, with per-train costs pegged at around Rs 80 crore and infrastructure at Rs 70 crore per route.
