The Delhi government is set to launch a pilot run of hydrogen fuel cell buses under the Delhi Transport Corporation (DTC) in partnership with NTPC, as part of the capital's push toward zero-emission public transport. Delhi Transport Minister Pankaj Kumar Singh announced the initiative on 28 May, describing it as a key milestone in the city's clean mobility transition.

Key Developments

An initial deployment of hydrogen fuel cell buses is currently underway in coordination with NTPC. The buses are proposed to operate under the Gross Cost Contract (GCC) model, with DTC facilitating operational deployment. Operational expenditure at approved GCC rates will be borne by DTC, while costs beyond the GCC framework are being explored through NTPC's CSR support mechanism and other arrangements in consultation with the concerned agencies.

What the Government Said

'Delhi is steadily moving towards clean, future-ready public mobility solutions. Hydrogen fuel technology represents an important step in our journey towards sustainable and environmentally responsible transport systems,' said Minister Pankaj Kumar Singh.

He added: 'Through collaboration with organisations such as NTPC, we are exploring innovative pathways to introduce advanced zero-emission technologies that can strengthen Delhi's public transport network while contributing to cleaner air and a greener future.'

Operational and Financial Framework

The Delhi Government, DTC, NTPC, and other stakeholders are currently working to finalise operational modalities and a formal Memorandum of Understanding (MoU) to facilitate the commencement of hydrogen fuel cell bus operations in the National Capital. The proposed cost-sharing structure reflects a collaborative model where public transport infrastructure costs are partially offset through NTPC's corporate social responsibility commitments.

Why Hydrogen Buses Matter for Delhi

Hydrogen fuel cell buses produce zero tailpipe emissions, making them a compelling option for a city that routinely ranks among the world's most polluted capitals. Unlike battery-electric buses, hydrogen-powered vehicles offer faster refuelling times and longer operational range — advantages that could make them suitable for high-frequency DTC corridors. This initiative complements Delhi's ongoing transition, which already includes a large fleet of electric buses under the DTC network.

Notably, this is among the first structured attempts by an Indian state government to integrate hydrogen fuel cell technology into a mass urban transit system through a formal public-sector partnership. The outcome of this pilot could inform hydrogen mobility policy for other Indian metros grappling with air quality and fleet decarbonisation challenges.

What Comes Next

The MoU between the stakeholders is expected to be finalised before operations commence. Once signed, the pilot will test real-world performance, maintenance costs, and passenger experience — data that will be critical in deciding whether hydrogen buses are scaled up across Delhi's broader public transport network.
