India’s first hydrogen train: 6 things passengers should know before its launch
India's first hydrogen-powered trainset, built by the Integral Coach Factory (ICF), Chennai, is expected to be launched around July 17, 2026, following Railway Board approval given in a letter dated May 22, 2026
The train will operate on the 89-km Jind-Sonipat route in Haryana, under Northern Railway's Delhi Division, halting at 12 intermediate stations
The trainset is a converted Diesel Electric Multiple Unit (DEMU) rake fitted with a 1,200 kW hydrogen fuel cell propulsion system, and has undergone trials by the Research Designs and Standards Organisation (RDSO)
A dedicated hydrogen production and refuelling facility has been set up at Jind, licensed by the Petroleum and Explosives Safety Organisation (PESO) for storage and dispensing of compressed hydrogen gas
On launch, it is expected to become the world's longest and most powerful hydrogen trainset on the Broad Gauge platform, joining a small group of countries (Germany, Japan, China, US, Switzerland) exploring hydrogen rail traction
Hydrogen Fuel Cell Technology (PEMFC)
The train uses a Proton Exchange Membrane Fuel Cell (PEMFC) as its primary power source, with a battery bank as a secondary source to meet peak power demand. A PEMFC is an electrochemical device that combines hydrogen and oxygen across a proton-conducting polymer membrane to generate electricity, with water vapour as the only emission — a concept UPSC tests both as a green-energy mechanism and as a component of India's larger hydrogen economy push.
Key Details
- Working principle: hydrogen is fed to the anode, where a platinum catalyst splits it into protons and electrons; the membrane allows only protons to cross to the cathode, forcing electrons through an external circuit (generating current), where they recombine with oxygen and protons at the cathode to form water
- Hydrogen's energy density (~120 MJ/kg) is roughly 2.8 times that of diesel (~43 MJ/kg), per Indian Railways' own comparison
- PEMFCs operate at relatively low temperatures (below 100°C) and can respond dynamically to changing power loads — well suited to traction applications
- India's train uses a hybrid architecture: PEMFC (primary) + battery bank (secondary, for peak/average load balancing)
The Jind-Sonipat train's core innovation is converting a diesel DEMU into a hydrogen-fuel-cell-hybrid unit, directly applying PEMFC principles to Indian rolling stock for the first time.
National Green Hydrogen Mission (2023)
The Union Cabinet approved the National Green Hydrogen Mission on January 4, 2023, to make India a global hub for the production, use, and export of green hydrogen and its derivatives. The hydrogen train is a downstream application of this broader national push toward hydrogen as a clean fuel across sectors — transport, industry, and energy storage.
Key Details
- Initial outlay: ₹19,744 crore, including ₹17,490 crore for the SIGHT (Strategic Interventions for Green Hydrogen Transition) programme, ₹1,466 crore for pilot projects, and ₹400 crore for R&D
- Targets: green hydrogen production capacity of at least 5 million metric tonnes per annum (MMTPA) by 2030, backed by ~125 GW of additional renewable energy capacity
- Expected to attract over ₹8 lakh crore in investments and create over 6 lakh jobs by 2030
- "Green" hydrogen specifically refers to hydrogen produced via electrolysis of water using renewable electricity — as distinguished from "grey" (from natural gas) or "blue" (grey + carbon capture) hydrogen; the Jind facility uses electrolysis-based green hydrogen
The hydrogen train pilot operationalises the Mission's transport-sector ambitions, alongside its industrial and export goals, and demonstrates a domestic use case for green hydrogen produced at scale.
Indian Railways' Net Zero Carbon Emitter Target (2030)
Indian Railways has set a target to become a Net Zero Carbon Emitter by 2030, one of the first large railway networks globally to commit to such a timeline. The hydrogen train fits into this decarbonisation roadmap alongside broader electrification efforts.
Key Details
- Key strategies: full electrification of Broad Gauge routes, procurement of renewable energy, energy efficiency improvements, and afforestation
- As of the latest published figures, over 80% of the Broad Gauge network (52,508 of 65,141 route km) stood electrified
- Projected 2029-30 energy demand: ~8,200 MW, requiring an estimated ~30,000 MW of renewable capacity to fully offset emissions
- Complementary initiatives: three-phase electric locomotives with regenerative braking, Head-On Generation (HOG) technology replacing diesel generator cars, and solar/wind capacity addition at stations and depots
While electrification remains the primary decarbonisation lever, hydrogen fuel cell trains offer an alternative for routes or duty cycles less suited to overhead electrification, complementing the 2030 net-zero target.
Global Context — World's First Hydrogen Trains
Germany's Alstom-built Coradia iLint became the world's first hydrogen fuel cell passenger train to enter commercial service, a useful comparator for the Indian project's claimed "world's longest" status.
Key Details
- Coradia iLint entered service on September 16, 2018, on the Buxtehude-Bremervörde-Bremerhaven-Cuxhaven line in Lower Saxony, Germany
- Specifications: top speed 140 km/h, range 600-800 km on a full hydrogen tank, zero CO2 emission (only water vapour exhaust)
- Other countries exploring or piloting hydrogen trains include Japan, China, the United States, and Switzerland (the last on a narrow-gauge network)
India's Jind-Sonipat train — a 10-car, 2,400 kW combined-output Broad Gauge trainset — is described by Indian Railways as the world's longest and most powerful hydrogen trainset on the Broad Gauge platform, distinguishing it from Germany's narrower-gauge, lower-power Coradia iLint.
- Route: Jind-Sonipat, Haryana — 89 km, 12 intermediate stations, Northern Railway Delhi Division; train numbers 74010/74009
- Configuration: 10-car trainset — 2 Driving Power Cars (1,200 kW each, 2,400 kW combined) + 8 passenger coaches
- Top speed: 75 kmph; manufactured by Integral Coach Factory (ICF), Chennai; trials conducted by RDSO
- Expected launch: around July 17, 2026 (Railway Board approval granted May 22, 2026)
- Hydrogen energy density: ~120 MJ/kg vs diesel's ~43 MJ/kg
- National Green Hydrogen Mission outlay: ₹19,744 crore (approved January 4, 2023); target 5 MMTPA green hydrogen by 2030
- Indian Railways Net Zero Carbon target year: 2030
- World's first hydrogen passenger train: Coradia iLint (Germany), commercial service since September 2018
