Hydrogen Train rolls out today; leak detectors, auto shutdown, real-time monitoring on track, Pg8

Key Highlights:

• India's first hydrogen-powered train was flagged off by Prime Minister Narendra Modi from Jind, Haryana.
• The train operates on the Jind-Sonipat section of Northern Railway and incorporates multiple layers of safety features.
• It utilizes Proton Exchange Membrane (PEM) fuel cell technology to generate electricity onboard.
• The 10-coach train has an operational speed of 75 kmph and a capacity of approximately 2,600 passengers.
• This launch positions India among a select group of nations adopting clean technology in the railway sector.

Detailed Insights:

• The train generates electricity by reacting hydrogen stored in cylinders with oxygen from the atmosphere, with water vapor and heat as the only direct by-products.
• Safety systems include continuous monitoring for hydrogen leaks, unusual heat, flames, or smoke, along with an automatic shut-off system for hydrogen supply.
• Non-stop ventilation ensures that any potential hydrogen leaks are safely diluted and carried away.
• A dedicated hydrogen storage, compression, and dispensing facility established at Jind uses electrolysis to split water into hydrogen and oxygen.
• This initiative aligns with India's broader goals of adopting clean technology and promoting sustainable mobility, supporting the National Green Hydrogen Mission.
• The train is designed for high-capacity passenger operations on non-electrified or difficult-to-electrify routes.
• The project is part of the Hydrogen for Heritage initiative, which aims to deploy 35 hydrogen trains on ecologically sensitive and scenic routes.
• The train was developed by the Integral Coach Factory (ICF) in Chennai.

Scientific/Technical Concepts Involved:

• Proton Exchange Membrane (PEM) fuel cell: An electrochemical device that converts the chemical energy of hydrogen and oxygen into electrical energy, producing water and heat as by-products.
• Electrolysis: A chemical process that uses an electric current to split water (H₂O) into hydrogen (H₂) and oxygen (O₂).
• Green Hydrogen: Hydrogen produced by the electrolysis of water using electricity generated from renewable energy sources, resulting in zero carbon emissions.
