Indian Railways' Hydrogen Train Trial on the Delhi–Jind Corridor: A Defining Leap Toward Net-Zero Rail
How a 90-kilometre stretch in Haryana is poised to become the birthplace of India's first hydrogen-powered passenger train—and what it signals for the future of sustainable transport across the subcontinent.
📍 Delhi–Jind Route, Haryana — A representative image of the Northern Railway DEMU rake that is expected to be retrofitted with hydrogen fuel cell technology for the landmark trial run between Delhi and Jind, covering approximately 90 kilometres through one of the busiest commuter belts in the NCR region.
In the annals of Indian railway history, few moments have carried the symbolic weight of what is about to unfold on a modest 90-kilometre stretch between Delhi and Jind. Indian Railways, the fourth-largest railway network on the planet and the single largest employer in the country, is preparing to test its first-ever hydrogen fuel cell-powered train—a move that could fundamentally reshape the carbon footprint of one of the world's most heavily used transportation systems.
The trial, slated for the Delhi–Jind section under the Northern Railway zone, is not merely a technological showcase. It represents the confluence of India's climate commitments, its energy security imperatives, and its longstanding ambition to modernise a rail network that moves over 8 billion passengers annually. If successful, this single prototype could pave the way for a fleet of zero-emission trains crisscrossing the subcontinent by the end of this decade.

The Genesis: Why Hydrogen, and Why Now?
To understand the significance of the Delhi–Jind trial, one must first appreciate the sheer scale of Indian Railways' diesel dependency. Despite aggressive electrification drives—over 94% of the broad-gauge network now stands electrified—there remain significant stretches, particularly in regional and semi-urban corridors, where diesel multiple units (DEMUs) continue to ply. These DEMUs, workhorses of the non-electrified sections, collectively consume hundreds of millions of litres of diesel annually, emitting substantial volumes of carbon dioxide, nitrogen oxides, and particulate matter.
The Union Ministry of Railways, in alignment with India's Panchamrit climate goals announced at COP26, committed to making the entire railway network a net-zero carbon emitter by 2030. Electrification alone cannot achieve this—especially on low-density routes where the capital expenditure for overhead catenary systems is difficult to justify economically. Enter green hydrogen: a fuel that, when consumed in a fuel cell, produces nothing but water vapour and electricity. No combustion. No tailpipe emissions. No noise beyond the hum of electric traction motors.
The Delhi–Jind Corridor: Why This Stretch?
The choice of the Delhi–Jind section for the inaugural trial is far from arbitrary. Situated in the bustling Northern Railway zone, this corridor connects the national capital with an important agricultural and commercial hub in Haryana. The line sees a healthy mix of passenger and light freight traffic, yet it is not so congested as to pose insurmountable logistical challenges for a prototype trial. Crucially, the section offers a representative blend of operational conditions—moderate gradients, a mix of urban and rural terrain, and ambient temperature variations that will test the fuel cell's thermal management systems across seasons.
Delhi–Jind also benefits from proximity to the railway's technical headquarters and the research institutions clustered in the National Capital Region. The Northern Railway's engineering teams, in collaboration with the IROAF and technical partners, can monitor every aspect of the trial with relative ease. Moreover, the political symbolism of launching a green technology demonstrator from the national capital is not lost on policymakers keen to project India's climate leadership on the global stage.
Under the Hood: How the Hydrogen Train Works
At its core, the hydrogen train being developed for the Delhi–Jind trial is a retrofit—a conversion of an existing 1,600-horsepower DEMU rake into a hydrogen fuel cell-electric hybrid. The diesel power pack is removed and replaced with a modular system comprising hydrogen storage cylinders, a proton exchange membrane (PEM) fuel cell stack, lithium-ion buffer batteries, and power conditioning units. Here is a simplified breakdown of the key components:
| Component | Function | Specification (Tentative) |
|---|---|---|
| Hydrogen Storage Tanks | Store compressed gaseous hydrogen at 350 bar | Type IV composite cylinders; ~180–220 kg H₂ capacity |
| PEM Fuel Cell Stack | Converts H₂ + O₂ → electricity + H₂O | 700–800 kW net output; ~55–60% efficiency |
| Buffer Battery Pack | Handles peak loads, regenerative braking energy | Lithium-titanate (LTO); ~200–250 kWh |
| Traction Motors | Drive the wheels via existing bogie-mounted motors | AC asynchronous; ~1,200 HP combined |
| Power Management System | Intelligently distributes load between fuel cell & battery | AI-optimised energy dispatch algorithm |
| Refuelling Infrastructure | Green hydrogen production & dispensing at Jind depot | On-site electrolyser; ~200 kg/day capacity |
The fuel cell operates most efficiently at a steady load, so the buffer battery plays a critical role—absorbing the spikes when the train accelerates from a station stop and capturing energy during regenerative braking. This hybrid architecture ensures that the hydrogen consumption per kilometre remains within economically viable limits. Early estimates suggest the train will consume approximately 0.45 to 0.55 kilograms of hydrogen per kilometre, translating to an operational cost that, while currently higher than diesel, is expected to fall sharply as green hydrogen production scales up across India.
The Green Hydrogen Ecosystem: Beyond the Train Itself
No discussion of hydrogen trains is complete without addressing the fuel supply chain. A hydrogen train is only as green as the hydrogen it consumes. Recognising this, Indian Railways has partnered with the Ministry of New and Renewable Energy (MNRE) and several public-sector undertakings to establish a green hydrogen production and refuelling facility at the Jind end of the corridor.
The proposed setup includes a 2.5-megawatt solar photovoltaic plant coupled with a polymer electrolyte membrane (PEM) electrolyser capable of producing around 200 kilograms of green hydrogen per day—sufficient to support daily trial operations with a margin for expansion. The entire chain, from sunlight to traction, is designed to be carbon-neutral: solar panels capture energy, the electrolyser splits water into hydrogen and oxygen, the hydrogen is compressed and stored, and the fuel cell converts it back into electricity to move the train.
💡 Did You Know? A single hydrogen-powered train running on the Delhi–Jind route is expected to eliminate approximately 4,400 tonnes of CO₂ emissions annually compared to an equivalent diesel-powered DEMU. Over a 25-year operational lifespan, that is over 110,000 tonnes of CO₂ avoided—equivalent to planting roughly 182,000 mature trees.
Global Context: Lessons from Germany and Beyond
India is not operating in a vacuum. The global benchmark for hydrogen rail technology remains Alstom's Coradia iLint, which entered commercial service in Germany's Lower Saxony region in 2018. The iLint has since been tested or deployed in Austria, the Netherlands, Sweden, and France, accumulating hundreds of thousands of incident-free kilometres. Alstom reports fuel cell efficiency rates exceeding 60% and availability figures comparable to diesel units. Several of the engineers involved in the Delhi–Jind project have studied the German deployment closely, adapting lessons to Indian conditions—higher ambient temperatures, dustier environments, and a vastly different passenger loading profile.
However, India's approach differs in one fundamental respect: cost sensitivity. Where European operators benefit from substantial green subsidies and carbon credit mechanisms, Indian Railways must justify the hydrogen transition on a rupee-per-kilometre basis. This has driven a strong emphasis on indigenous component development. The fuel cell stack, the hydrogen storage cylinders, and the power management software are all being developed with significant domestic content, involving institutions such as the Indian Institute of Technology (IIT) Delhi, the Banaras Locomotive Works, and private sector partners from the automotive and energy sectors.
The Road Ahead: Challenges and Milestones
For all the optimism surrounding the Delhi–Jind trial, significant hurdles remain. The first is the cost of green hydrogen itself. As of early 2025, green hydrogen in India costs approximately ₹350–₹450 per kilogram, making the per-kilometre fuel cost of the hydrogen train roughly 2.5 to 3 times that of its diesel equivalent. The National Green Hydrogen Mission, launched in 2023 with an outlay of ₹19,744 crore, aims to bring this down to below ₹200 per kilogram by 2027–28 through economies of scale, electrolyser manufacturing incentives, and renewable energy integration. Until that price parity is achieved, hydrogen trains will rely on a combination of government subsidy, carbon credit revenue, and the intangible but politically potent value of zero-emission operations.
The second challenge is safety regulation. Hydrogen is a notoriously leak-prone gas with a wide flammability range (4% to 75% in air) and a low ignition energy. The fuel cell system must be designed to detect and safely vent any hydrogen accumulation, and the storage cylinders must withstand crash loads far exceeding normal operational stresses. Indian Railways is working with the Petroleum and Explosives Safety Organisation (PESO) to develop a comprehensive regulatory framework specifically for hydrogen-powered rolling stock—a framework that does not yet exist in India.
The third challenge is human capital. Operating a hydrogen train requires a different skill set than a diesel or electric locomotive. Drivers need training on the nuances of fuel cell behaviour, emergency protocols for hydrogen leaks, and the interpretation of new cockpit instrumentation. Maintenance depot staff must be upskilled to handle high-pressure gas systems, fuel cell stack replacement, and battery management. Northern Railway has already identified a cohort of 40 drivers and 60 maintenance technicians for intensive training ahead of the trial.

What This Means for the Indian Passenger
For the thousands of daily commuters on the Delhi–Jind route—farmers transporting produce, students commuting to colleges in Rohtak and Delhi, small-business owners shuttling between Haryana's vibrant market towns—the hydrogen train promises a noticeably different travel experience. The absence of diesel engine vibration means a smoother, quieter ride. The elimination of exhaust fumes means station platforms at Bahadurgarh, Rohtak, and Jind will breathe cleaner air. And while ticket prices are unlikely to change immediately, the long-term operational economics of hydrogen—once green hydrogen costs decline—could translate into more competitive fares on non-electrified routes that currently bear the cost burden of diesel fuel.
Beyond the passenger experience, the trial serves as a powerful signal to India's manufacturing ecosystem. A successful hydrogen train creates demand for electrolysers, fuel cells, composite cylinders, and power electronics—all sectors where Indian industry is actively building capacity. The ripple effects could extend to heavy trucking, shipping, and industrial heating, where hydrogen is also being explored as a decarbonisation pathway.
Environmental and Strategic Implications
The environmental arithmetic is compelling. Indian Railways currently emits approximately 6.5 million tonnes of CO₂ annually from its diesel operations—a figure that has been steadily declining thanks to electrification but which cannot reach zero without addressing the remaining diesel fleet. Retrofitting just 10% of the existing DEMU fleet with hydrogen fuel cells could cut over half a million tonnes of annual emissions. When combined with the railways' parallel push toward 100% renewable energy for its electrified traction (through solar and wind power purchase agreements), the path to net-zero by 2030 starts to look technically achievable.
Strategically, the hydrogen train programme reduces India's exposure to imported crude oil. Every litre of diesel displaced by green hydrogen is a litre of oil that India does not need to import—a consideration that resonates deeply in New Delhi's policy circles, where energy security is woven into every major infrastructure decision. At current import parity prices, a fleet of 50 hydrogen trains could save India over ₹300 crore annually in foreign exchange outflows on diesel imports alone.
A Defining Chapter in India's Railway Story
Indian Railways has always been more than a transport utility. It is a symbol of national integration, a lifeline for millions, and a canvas upon which India's technological ambitions have been repeatedly painted—from the first steam locomotives of the 1850s to the high-speed Vande Bharat expresses of today. The hydrogen train trial on the Delhi–Jind corridor is the latest chapter in that unfolding story, one that marries the romance of rail travel with the urgent pragmatism of climate action.
As the prototype rake undergoes its final integration tests and the solar-powered electrolyser at Jind nears commissioning, the eyes of the global railway community are turning toward this unassuming stretch of track in Haryana. Success here would place India in an elite club of nations operating hydrogen trains, alongside Germany and France. More importantly, it would demonstrate that the technology can be adapted to the unique demands of a developing country—high passenger volumes, extreme weather, cost constraints—and still deliver on its environmental promise.
The Delhi–Jind hydrogen train is not a silver bullet. It will not, on its own, solve Indian Railways' emissions problem or India's broader energy challenges. But it is a crucial proof of concept, a testbed for innovation, and a beacon of intent. It tells the world that India is willing to invest in frontier technology, to build the necessary infrastructure from the ground up, and to take calculated risks in pursuit of a cleaner future. That, in the final analysis, is what sustainable development looks like—not a single dramatic leap, but a series of determined, well-engineered steps along a 90-kilometre railway line in the heart of Haryana.
