Technical Innovations on Track
The Ministry of Railways has given the go-ahead for India's first hydrogen-powered 10-coach Diesel Electric Multiple Unit (DEMU) train. This train generates electricity from hydrogen fuel cells, emitting only water vapor and steam. It utilizes Distributed Power Rolling Stock (DPRS) technology, which spreads power generation across the train rather than using a single large engine. The approval came after thorough safety and technical reviews by the Research Designs and Standards Organisation and the Commissioner of Railway Safety. However, passenger service awaits further approvals, including detailed maintenance and safety audits.
Economic Hurdles for Sustainable Mobility
While promoted as a key step for greener transport, the project faces economic challenges. Indian Railways has largely completed electrification of its broad-gauge network (over 99%), providing a more cost-effective and efficient solution than hydrogen. Analysts note the significant investment of ₹111.83 crore for this pilot's retrofit and infrastructure, which contrasts with the efficiency of the existing electric grid. A specialized hydrogen plant in Jind, using a 1 MW PEM electrolyzer, supports this localized experiment. The high current cost of green hydrogen, considerably more than diesel per unit of energy, raises doubts about scaling this technology without substantial government subsidies.
Financial Sustainability Questions
The project's long-term financial viability is a major concern. With Indian Railways operating on a tight budget (an estimated operating ratio of 98.43% for FY 2025-26), investing in expensive new fuels is challenging. Critics suggest that focusing on hydrogen while still completing the final 1% of electrification might not be the best use of limited funds. Operational risks also exist, including the need for specialized maintenance at the Shakurbasti depot and the current reliance on diesel locomotives for moving the train during off-site maintenance. Advanced leak and flame detection sensors add another layer of operational complexity not present in traditional electric systems.
Looking Ahead
Despite these obstacles, the "Hydrogen for Heritage" initiative is a high-profile project, with plans for up to 35 similar trainsets. The Jind-Sonipat trial will be crucial in determining if hydrogen trains can move beyond experimental use. Success will depend on improvements in green hydrogen production efficiency and demonstrated cost-competitiveness, as India pursues its net-zero 2030 targets.
