New Delhi: India has taken a significant leap in sustainable transportation with the launch of its first hydrogen powered train, marking the country’s entry into a select group of nations exploring hydrogen based rail technology. Flagged off by Prime Minister Narendra Modi in Haryana, the train operates without diesel fuel or overhead electric wires, generating its own electricity through advanced hydrogen fuel cell technology.
Unlike conventional electric trains that rely on external power lines, the hydrogen train functions as a moving power station. It stores hydrogen in high pressure tanks, where the gas reacts with oxygen from the air inside fuel cells. This electrochemical process produces electricity that powers the train’s electric motors, while the only direct byproducts are water and heat, making it a zero tailpipe emission transport system.
The train carries hydrogen cylinders in specially designed compartments, where a catalyst separates hydrogen into protons and electrons. The electrons flow through an external circuit to generate electricity for the traction motors, while the hydrogen ions combine with oxygen to form water vapour. Since no fuel is burned, the train operates more quietly and produces no harmful exhaust emissions.
One of the biggest advantages of hydrogen technology is that it eliminates the need for overhead electric wires. Because the train generates electricity onboard, it can run efficiently on non electrified railway routes, making it particularly suitable for remote and heritage rail sections where installing electric infrastructure would be expensive.
Developed under the Hydrogen for Heritage initiative, the train will initially operate on the Jind Sonipat route in Haryana. It features regenerative braking, advanced fire and smoke detection systems, CCTV surveillance and modern passenger facilities. The regenerative braking system also stores energy in onboard batteries, improving efficiency and reducing hydrogen consumption.
Although the train produces only water at the point of operation, its overall environmental impact depends on how the hydrogen is manufactured. Green hydrogen, produced using renewable energy, offers the lowest carbon footprint.
The launch supports India’s National Green Hydrogen Mission and reflects the country’s broader goal of reducing dependence on fossil fuels while modernising one of the world’s largest railway networks with cleaner and more sustainable technology.
