India's first hydrogen-fuel-cell train set to run

Indian Railways clears an indigenous 10-car hydrogen fuel-cell trainset for the Jind-Sonipat section in Haryana, with water vapour as its only emission.

What happened

• Indian Railways has approved the introduction of a 10-car Hydrogen Fuel Cell-based trainset on the dedicated Jind-Sonipat section of Northern Railway in Haryana, the country's first such service.
• The trainset runs on a 1200 KW hydrogen fuel-cell propulsion system and will operate at a maximum speed of 75 kmph.
• The fuel cell generates electricity through a chemical reaction using hydrogen; its only emission is water vapour, with no carbon dioxide, oxides of nitrogen, or particulate matter at the point of use.
• An indigenous hydrogen storage and refuelling facility has been set up at Jind, and the Petroleum and Explosives Safety Organisation (PESO) has granted the licence for storage and dispensing of compressed hydrogen gas.
• A hydrogen compression system has been provided; safety sensors including hydrogen leak detectors and flame detectors are installed, and operation-and-maintenance manuals have been approved by the Research Designs and Standards Organisation (RDSO).
• The approval mandates 24x7 monitoring of the hydrogen refuelling system and the deployment of trained, certified personnel; the maintenance facility is proposed at Shakurbasti.
• The project is positioned as support for India's national clean-energy and net-zero carbon-emission goals.

Background & context

Railway traction in India has moved through three broad generations: steam, then diesel, then electric. Indian Railways has already electrified the bulk of its broad-gauge network and has set a target of becoming a "net-zero" carbon emitter, so the remaining decarbonisation challenge sits on the routes where stringing overhead electric wire is uneconomic — short, low-traffic, branch and heritage sections. A hydrogen fuel-cell trainset is the technology aimed squarely at this gap: it carries its own energy on board as compressed hydrogen and needs no overhead equipment, while still emitting nothing but water at the point of use. The Jind-Sonipat pilot is the first roll-out under the railways' broader "Hydrogen for Heritage" thinking, under which a fleet of hydrogen trains has been planned for narrow-gauge heritage and selected branch lines.

A hydrogen fuel cell is not an engine that burns fuel and it is not a battery that stores charge. It is an electrochemical device: hydrogen fed to the anode and oxygen (from air) drawn to the cathode combine across a membrane, releasing electrons that flow as electric current, and the only by-product of the reaction is water. That electricity then drives the same kind of traction motors an ordinary electric multiple unit uses. This is why a hydrogen train is best understood as an electric train that makes its own electricity on board, rather than a wholly new kind of locomotion. The same fuel-cell principle powers fuel-cell electric road vehicles and is being explored for shipping and stationary power.

Internationally, the technology is no longer experimental. Germany ran the world's first hydrogen fuel-cell passenger trains in regular service (the Coradia iLint trainsets), and Japan, China and the United States have all run hydrogen rail demonstrators or services. With this approval India joins that select group of countries exploring hydrogen for cleaner rail transport, while emphasising the indigenous design of the storage and refuelling chain rather than importing a turnkey foreign system. The release frames India's entry as a domestic-capability story: the storage-and-refuelling facility at Jind is described as indigenous, and the safety, manuals and monitoring regime are anchored in Indian regulators (PESO and RDSO).

For Prelims

• What it is: India's first hydrogen fuel-cell trainset, a self-propelled multiple-unit drawing traction power from on-board hydrogen fuel cells rather than from overhead electric lines or a diesel engine.
• Pilot route: Jind-Sonipat section, Northern Railway, in Haryana. Maintenance facility proposed at Shakurbasti.
• Configuration: 10-car trainset · 1200 KW fuel-cell propulsion · maximum speed 75 kmph.
• Emission profile: water vapour only at the point of use — hydrogen reacts electrochemically to generate electricity, so there is no tail-pipe carbon dioxide.
• Refuelling chain: an indigenous hydrogen storage and refuelling facility at Jind, with a hydrogen compression system; storage and dispensing of compressed hydrogen gas licensed by PESO (Petroleum and Explosives Safety Organisation, the nodal authority for explosives, compressed gases and petroleum safety in India).
• Safety & standards: hydrogen leak detectors and flame detectors fitted; operation-and-maintenance manuals approved by RDSO (the standards and research wing of Indian Railways); 24x7 monitoring of the refuelling system mandated with trained certified personnel.
• Global company: with this, India joins Germany, Japan, China and the United States, which have already run or trialled hydrogen rail.
• Which colour of hydrogen? The release does not specify the production route (green / grey / blue). Fuel-cell trains are "zero-emission" only at the point of use; the upstream climate footprint depends on how the hydrogen itself was produced, so the safe statement is that the train emits only water vapour, not that the whole fuel chain is carbon-free.
• What it is NOT: it is not a battery-electric train (it carries hydrogen, not a charged battery pack); it is not a diesel or CNG train (there is no combustion of fuel for traction); and it is not dependent on overhead electric wires like a conventional EMU. It is also not a hydrogen internal-combustion train — the hydrogen is consumed in a fuel cell, not burnt.
• The clean-traction set it belongs to (for "how many / which of these" questions): the family of zero- or low-emission rail traction options being pursued in India includes conventional electric (overhead line), battery-electric, and now hydrogen fuel-cell traction; on the energy-source side the related ecosystem includes the National Green Hydrogen Mission, the push for green hydrogen and electrolysers, and railway solarisation. Keep PESO (gas safety) and RDSO (railway standards) paired with this entity.

Why it matters

The problem this addresses is the "last leg" of rail decarbonisation. Electrification with overhead lines is the cheapest clean option on dense trunk routes, but it makes little economic sense on short, lightly used branch lines and heritage tracks — yet those routes still run diesel and still emit. A hydrogen fuel-cell train removes the need for overhead wiring entirely while keeping emissions at the point of use down to water, which makes it a candidate technology precisely for the corridors that electrification leaves behind. For an examiner this is the conceptual hook: hydrogen rail is not a competitor to mainline electrification, it is a complement to it on the routes electrification cannot reach cheaply.

The release also reads as an indigenisation and energy-security story. By building the storage-and-refuelling facility domestically and routing safety and standards through Indian regulators, the railways treat the pilot as a way to develop home-grown capability in hydrogen handling — capability that has spillovers into the wider hydrogen economy the government is trying to seed. Demand from a captive, safety-conscious buyer like the railways can help anchor a domestic market for hydrogen production, compression, storage and dispensing, lowering costs for other users over time. Set against India's net-zero commitment and its broader green-hydrogen ambitions, a visible, public-facing hydrogen train serves both as a working demonstrator and as a signal of policy direction.

There are honest limits worth carrying. Hydrogen is flammable and is stored under high pressure, which is why the elaborate safety regime — leak and flame detectors, PESO licensing, 24x7 monitoring and certified staff — is built into the very approval. The overall climate benefit also depends on how the hydrogen is produced; a fuel-cell train fed by hydrogen made from fossil energy is far less clean across its full life-cycle than one fed by green hydrogen made with renewable electricity. And at 75 kmph on a single pilot section, this is a demonstrator, not yet a fleet — its value lies in proving the operational and safety model before scale-up.
