PM to flag off India’s first hydrogen train: How they work, and why they haven’t picked pace globally

Political & Constitutional Dimensions: The government views the hydrogen train as a flagship initiative under the National Hydrogen Mission and a step towards decarbonizing transport. It aligns with the Prime Minister's vision of Aatmanirbhar Bharat (self-reliance) and green mobility. Constitutionally, the directive principles under Article 48A (protection of environment) and fundamental duty under Article 51A(g) compel the state to promote environmental sustainability. However, critics may question the high cost (Rs 136 crore) and import dependence for the fuel cell, arguing that the same expenditure could have been used for electrification of more rail sections. The project's future depends on operational performance, and the Railways has not announced further expansion, indicating a cautious approach.

Economic & Financial Impact: The Rs 136-crore project involves capital expenditure on retrofitting old diesel electric multiple unit rakes with a zero-emission hydrogen-electric propulsion system. The fuel cell import from Canada incurs foreign exchange costs, but the operational savings from replacing diesel could be significant. Hydrogen consumption is estimated at 300 kg per day per train; the cost of green hydrogen (if used) is currently high. The fueling facility at Jind with 3000 kg capacity and chiller plant adds to infrastructure costs. In the long term, if scaled, hydrogen trains can reduce India's diesel import bill and create a domestic manufacturing ecosystem for fuel cells, batteries, and hydrogen production. However, the economic viability is yet to be proven at scale.

Social Dimensions: Hydrogen trains produce zero tailpipe emissions, contributing to improved air quality in communities along railway corridors. This is especially relevant for regions like Haryana with high pollution levels. The train can carry 682 passengers, offering a cleaner alternative for short-haul travel. However, the high-pressure storage of hydrogen (200-500 bar) raises safety concerns in densely populated areas. The Railways has addressed this through a chiller plant and fueling facility at Jind, but public acceptance of hydrogen as a fuel may require awareness campaigns. Employment generation from the hydrogen supply chain (production, storage, maintenance) is a positive social impact, but the technology is still nascent.

Governance & Administrative Aspects: Implementation challenges include safe transportation of highly flammable hydrogen at high pressure, low hydrogen production levels, and difficult logistics. The Railways has set up a dedicated fueling facility at Jind, but scaling across the network would require extensive infrastructure and regulatory approvals. The project was executed by Northern Railway with Medha as the prime contractor, showing public-private partnership. However, the lack of any other announced hydrogen train projects indicates that the model is still experimental. The Ministry of Railways' sanction on May 22 after trials suggests a rigorous approval process. Coordination with the Ministry of New and Renewable Energy (for hydrogen production) and Ministry of Environment (for safety norms) will be crucial for future expansion.

International Perspective: Globally, hydrogen trains are still in early stages. Alstom's Coradia iLint in Germany (2018) is the only operational hydrogen train service, and it operates on short routes. Japan, China, and the US have launched their own hydrogen trains but none have achieved mass deployment. The technology is evolving to handle higher passenger and freight loads. India's trainset, being one of the longest and most powerful, is a significant step, but its success will be closely watched. The import of fuel cells from Canada highlights global supply chain dependencies. The International Energy Agency (IEA) and other bodies advocate hydrogen as a clean fuel, but infrastructure and cost remain barriers. India's experience can offer lessons for developing countries adopting hydrogen mobility.
