GREATER NOIDA, Nov. 18 -- The Yamuna Expressway industrial development authority's (Yeida) plan to hold trial runs of hydrogen-powered buses has hit a hurdle due to lack of a detailed plan on deploying drivers and conductors to run these buses to the Noida International Airport. Yeida has been unable to finalise staff, including driver or conductor, so far as the Authority does not want to engage any private agency to run this ambitious project meant to provide a sustainable eco-friendly mode of commute in this region.

The Authority believes that the private operator may not fit to run this facility. Thus, the Authority wants to engage the UPSRTC to provide drivers and the conductors who can help in starting this facility," said Yeida's additional CEO Nagendra Prasad. Hydrogen-powered buses operated by the NTPC were to ferry passengers between Noida, Greater Noida, and the upcoming the airport in Jewar, Yeida beginning November 16. Now the project trial has been delayed for an indefinite time, said officials. Yeida officials said the UPSRTC is reluctant and rather wants to provide their diesel- run buses. "The Authority wants that they provide the drivers and helpers to help in the trial-run of four buses initially. It the trial is successful, the Authority will arrange more hydrogen buses," said another Yeida official. "The trial run that was to begin from November 16, has been delayed. Now, it will start only if the UPSRTC gives staff or we hire that private operator via a tender process that may take longer time," said another official.
