PM Modi Inaugurates India’s First Hydrogen Train on Jind-Sonipat Route

India has taken a major step towards green and sustainable transportation with the launch of its first hydrogen-powered train on the Jind-Sonipat route in Haryana. The project reflects India’s commitment to reducing carbon emissions, promoting clean energy, and modernizing its railway network. Hydrogen-powered trains are expected to play an important role in achieving the country’s long-term climate and net-zero goals.

What is a Hydrogen Train?

A hydrogen train is a train that runs using hydrogen fuel cells instead of diesel. The fuel cells generate electricity by combining hydrogen with oxygen, which powers the train’s electric motors. Unlike diesel trains, hydrogen trains emit only water vapour and heat, making them an eco-friendly mode of transport. They are an important step towards cleaner and more sustainable rail transportation.

How Does a Hydrogen Train Work?

A hydrogen train generates electricity through hydrogen fuel cells instead of using a diesel engine. This electricity powers the train’s electric motors, making it a clean and energy-efficient mode of rail transport.

• Hydrogen Storage: Compressed hydrogen gas is stored in specially designed high-pressure tanks mounted on the train.
• Supply to Fuel Cell: The stored hydrogen is supplied to the fuel cell stack through a controlled fuel delivery system.
• Oxygen Intake: Oxygen from the surrounding air enters the fuel cell through the air intake system.
• Electrochemical Reaction: Inside the fuel cell, hydrogen reacts with oxygen in an electrochemical process without combustion.
• Electricity Generation: The reaction produces electricity, which is used to operate the train’s electric traction motors.
• Battery Support: Excess electricity generated by the fuel cells is stored in onboard lithium-ion batteries and used during acceleration or when additional power is required.
• Train Propulsion: The electric motors convert electrical energy into mechanical energy, driving the wheels and moving the train.
• Zero Harmful Emissions: The only by-products of the fuel cell reaction are water vapour and heat, with no carbon dioxide or harmful pollutants released.
• Energy Efficiency: Fuel cells are more energy-efficient than conventional diesel engines and help reduce fuel consumption.
• Regenerative Braking: During braking, the train recovers some of the energy and stores it in the batteries, improving overall efficiency.
