Indian Railways Advocates Transition from Diesel Locomotives to Alternative Fuel Engines, Including Hydrogen
India is making significant strides in modernizing its railway system by increasing the use of battery and alternative fuel-powered train engines. This initiative comes as the country nears the completion of its electrification project, with only 405 route kilometers left to electrify out of a total of 70,117. The focus is now on phasing out approximately 2,500 diesel locomotives, which are primarily used for short and medium-distance routes. Officials have indicated that these diesel engines will either be retrofitted or replaced with cleaner alternatives to reduce environmental impact.
Transitioning from Diesel to Cleaner Alternatives
The Indian Railways is prioritizing the replacement of diesel locomotives, particularly those used in yard operations, shunting services, and last-mile freight connectivity. These operations still rely heavily on diesel due to sections of the rail network that are either not electrified or have intermittent electrification. While overhead electric traction will continue to be the backbone of railway operations, the introduction of battery-powered and alternative fuel solutions is being explored for specific operational needs where complete electrification is not feasible. This dual approach aims to enhance efficiency while minimizing carbon emissions.
Innovations in Propulsion Technology
Progress in cleaner propulsion systems is already evident. In September 2022, Concord Control Systems successfully retrofitted a 700-horsepower diesel locomotive to operate on a lithium ferro phosphate (LFP) battery. Recently, the company announced plans to develop the world’s largest hydrogen-fueled locomotive propulsion system, boasting 3,100 horsepower. This innovative locomotive is being designed for NTPC, a public sector utility, to transport coal to its power plants. Additionally, the Indian Railways is actively testing hydrogen-powered train technology, including the world’s longest hydrogen train set, which features ten coaches and a powerful 2,400 kW capacity on a broad-gauge platform.
Ongoing Pilot Projects and Future Plans
The Indian Railways has been experimenting with battery technologies for about six years. Chittaranjan Locomotive Works (CLW) has been tasked with constructing ten battery-powered locomotives, while Eastern Railway’s Kanchrapara workshop has converted a motor coach into a battery-cum-25 kV shunting engine. This engine is capable of pulling both freight and passenger trains at low speeds using battery power. Currently, Indian Railways still relies heavily on diesel locomotives for long-haul freight services, although most long-distance passenger trains have transitioned to electric traction powered by overhead lines.
International Collaborations and Future Deliveries
In a notable move towards cleaner freight operations, Siemens, a German company, was awarded a substantial contract worth Rs 26,000 crore in December 2022. This contract involves the supply and maintenance of 1,200 electric freight locomotives. The first batch of these advanced engines is expected to be delivered by May 2025. This collaboration underscores India’s commitment to modernizing its railway infrastructure and reducing its carbon footprint through innovative technology and international partnerships.
