The Government of India has initiated five pilot projects under the National Green Hydrogen Mission to explore the use of hydrogen in buses and trucks. The Ministry of New and Renewable Energy had earlier issued guidelines for implementing these pilot projects in the transportation sector, inviting proposals for various hydrogen-based vehicles, routes, and refuelling stations. After careful review, the Ministry sanctioned five pilot projects, which involve 37 vehicles (15 hydrogen fuel cell-based and 22 hydrogen internal combustion engine-based vehicles) and 9 hydrogen refuelling stations.
