Nepal’s increasing demands for commuting, travel, and logistics have resulted in an increase in annual vehicle registration from 47 thousand in 2002 to 576 thousand in 2022, a 13.4% average annual growth rate. Liquid fuels derived from petroleum oil are the major source of energy in the transport sector in Nepal. 51% of the total petroleum fuel consumed in Nepal is utilized in the transport sector. 

With no proven petroleum reserves, Nepal is completely dependent on imports to meet the demand for petroleum fuel, adding burden to the country’s increasing trade deficit, and raising concerns about the economic vulnerability and energy supply security. Hydrogen-powered fuel cell vehicles are a promising zero-emission alternative in decarbonizing the hard-to-hard-to-abate heavy-duty transportation sector by using hydrogen as a transportation fuel.
