A Technical Leap Forward
The official approval for India’s hydrogen-powered DEMU train marks a key development in the country's push for cleaner transportation. Unlike traditional rail electrification that demands extensive overhead infrastructure, this 10-coach train uses Distributed Power Rolling Stock (DPRS) technology. Its 2,400 kW power output makes it one of the most potent hydrogen train prototypes globally. The train has successfully completed technical assessments and oscillation trials by the Research Designs and Standards Organisation (RDSO), moving it from concept to operational readiness on the Jind-Sonipat route.
Infrastructure and Operational Challenges
Railway Board approval is just the start for this complex project. This system needs a specialized hydrogen setup, including on-site electrolyzers and high-pressure refueling stations. Currently, a 1-megawatt electrolyzer in Jind supports the train. Operational limits are also in place due to safety rules, requiring diesel locomotives for maintenance at the Shakurbasti shed. The train's use is currently confined to the Jind-Sonipat stretch, as the wider Indian railway network lacks the necessary hydrogen infrastructure for large-scale deployment.
Economic Doubts
While the train showcases India's engineering skills, its economic sense is under scrutiny. The estimated cost is ₹80 crore per trainset, plus an additional ₹70 crore per route for ground facilities. Critics argue that with over 93% of the broad-gauge network already electrified, the benefit of hydrogen trains is limited. The current high cost of green hydrogen makes it uncompetitive against diesel. The need for high-pressure cryogenic storage also adds weight to the train, potentially reducing passenger space. The initiative may remain a pilot project until green hydrogen production costs decrease significantly, which some predict could happen by 2030.
What Lies Ahead
The 'Hydrogen for Heritage' initiative plans to deploy 35 similar trainsets on non-electrified mountain and tourist routes. The Jind-Sonipat pilot is a crucial test, but broader success hinges on public-private partnerships to build modular refueling systems. The focus will be on whether this technology can transition from a localized experiment to a practical, cost-effective option for routes where electrification is not feasible.
