Delhi roads have welcomed a revolutionary public transit option with the launch of a hydrogen fuel cell bus that emits only pure water instead of smoke. Developed through a collaborative effort by Tata Motors, the Delhi Metro Rail Corporation (DMRC), and Indian Oil, this eco-friendly bus is currently operating on a key route in New Delhi, offering passengers a clean, modern, and highly affordable travel experience.

The vehicle utilizes Proton Exchange Membrane (PEM) fuel cell technology, combining hydrogen stored in ultra-strong carbon fiber cylinders on the roof with atmospheric oxygen to generate electricity. This chemical process powers the electric motor without any combustion, leaving only water droplets as a byproduct. The bus runs in both clockwise and counterclockwise directions from Central Secretariat to Safdarjung Tomb Metro Station, covering iconic landmarks like India Gate, Kartavya Path, and National Stadium for a nominal fare of just Rs 10 to 20.

To ensure passenger safety, the bus is equipped with high-tech sensors that can detect leaks and shut down the system within milliseconds, alongside real-time monitoring by engineers. Unlike traditional electric buses that require six to eight hours of charging, this hydrogen bus can be fully refueled in just five to seven minutes. Under the National Green Hydrogen Mission, India aims to produce 50 lakh metric tons of green hydrogen annually by 2030, paving the way for energy independence.
