Hydrogen On Delhi’s Roads: A Green Leap With Grey Areas

Clean Commute Meets Cost Reality

Rolled out on select routes as a pilot, the hydrogen buses are designed to cut urban pollution and showcase India’s commitment to net-zero goals. For now, however, limited refuelling points, imported components, and high hydrogen production costs mean this is more a technology demonstrator than a mass solution.

How The Hydrogen Bus Pilot Works

The buses use fuel-cell technology, converting hydrogen into electricity on board, emitting only water vapour. Authorities are closely tracking operating data, safety performance, and public feedback to decide whether to expand the fleet. Policy makers also see this as a test bed for domestic hydrogen production, storage, and standards.

Policy Push, Infrastructure Gap

Despite central and state-level backing under green hydrogen and urban mobility missions, the economics remain challenging. Green hydrogen is still significantly costlier than diesel or even battery-electric options, and Delhi currently has only a handful of refuelling and maintenance facilities dedicated to this technology.

Key Highlights

1. Delhi launches pilot fleet of green hydrogen buses on select routes
2. Fuel-cell buses offer zero tailpipe emissions and quieter operations
3. High hydrogen production and storage costs strain project economics
4. Limited refuelling and maintenance infrastructure slows scale-up
5. Pilot data will shape future policy on hydrogen versus electric buses
