Context:
Recently, the Railway Board officially approved the operation of the country's first indigenous hydrogen fuel cell-based train (DPRS 1200 kW DEMU). This train will run on the Jind-Sonipat rail section in Haryana and is set to prove to be a game-changer in achieving India's 'Net-Zero Carbon Emission' target.
About Hydrogen Trains:
-
-
- Hydrogen trains, or ‘hydrail’/H-trains, are electric trains that generate power onboard using hydrogen fuel cells instead of external electricity or diesel.
- They use Hydrogen Fuel Cell (HFC) technology, where hydrogen reacts with oxygen to produce electricity, with water vapour as the only byproduct, making them zero-emission at the point of use.

About Hydrogen Fuel Cell Technology:
-
-
- Hydrogen trains operate through electrochemical reactions:
- Hydrogen enters the anode and splits into protons and electrons
- Protons pass through the Proton Exchange Membrane (PEM)
- Electrons flow through an external circuit, generating electricity
- Oxygen combines with protons and electrons at the cathode
- Output: Electricity + Water vapour + Heat
- Hydrogen enters the anode and splits into protons and electrons
- The system has no combustion and minimal moving parts, making it quiet and efficient.

Significance for India:
-
-
- Decarbonisation of Railways: Supports Indian Railways’ goal of net-zero emissions by 2070 by reducing diesel dependency.
- Clean Energy Transition: Hydrogen trains offer zero tailpipe emissions, helping India transition to cleaner transport systems.
- Modernisation of Rail Network: Enables green mobility on non-electrified and heritage routes.
- Hydrogen for Heritage Initiative: Indian Railways plans to deploy 35 hydrogen trains on heritage and hill routes under this initiative.
- Decarbonisation of Railways: Supports Indian Railways’ goal of net-zero emissions by 2070 by reducing diesel dependency.

About National Green Hydrogen Mission:
-
-
- Approved in 2023, the mission aims to make India a global hub for green hydrogen.
- Key targets:
- 5 MMT annual green hydrogen production by 2030
- Potential expansion to 10 MMT with export growth
- Replacement of fossil fuels in sectors like steel, refining, and fertilisers
- 5 MMT annual green hydrogen production by 2030
- Approved in 2023, the mission aims to make India a global hub for green hydrogen.

Types of Hydrogen:
-
-
- Grey Hydrogen: Produced from fossil fuels (natural gas/coal) via steam methane reforming; emits CO₂.
- Blue Hydrogen: Produced from fossil fuels but with carbon capture and storage (CCS).
- Green Hydrogen: Produced via electrolysis using renewable energy; near-zero emissions.
- Grey Hydrogen: Produced from fossil fuels (natural gas/coal) via steam methane reforming; emits CO₂.

Conclusion:
India’s first hydrogen-powered train marks a major milestone in sustainable railway transformation. It aligns with the National Green Hydrogen Mission and India’s net-zero commitment by 2070. With proper scaling and infrastructure support, hydrogen trains can become a key pillar of India’s clean, efficient, and future-ready transport system.
