The project is being implemented by India’s largest power producer NTPC, which is supplying five hydrogen fuel cell buses to the Leh administration for intra-city service in the city. The state-run company has also built a refuelling station and captive solar plant of 1.7 megawatt for producing green hydrogen to fuel the buses. The Leh administration has leased 7.5 acres of land in the city for the infrastructure.
