Abstract
Nigeria's reliance on conventional fuels like gasoline and diesel has prompted the search for more affordable and sustainable alternatives. This study presents a techno-economic assessment of compressed natural gas (CNG) as an alternative fuel for the transport sector in Southwestern Nigeria. Results show that CNG adoption could reduce fuel costs by over ₦5,518 per 100 kilometers compared to petrol, providing substantial economic relief to transport operators. Beyond cost savings, CNG offers environmental benefits, including lower greenhouse gas emissions and improved air quality, helping to address the region’s environmental challenges. However, upfront costs for vehicle conversion kits and limited refueling infrastructure remain significant barriers. Nonetheless, long-term fuel savings, environmental gains, and potential government subsidies make CNG a viable and sustainable solution.
