Gas flaring within Nigeria's oil and gas sector leads to environmental degradation, public health risks, and substantial financial losses. Capturing this wasted resource offers opportunities to generate useful fuels whilst mitigating carbon emissions. Evaluating the conversion of flared gas into compressed natural gas reveals clear potential for supplying public transit, specifically the 220 vehicles comprising the Lagos Bus Rapid Transit system. Energy demand and associated carbon dioxide emissions were modelled up to the year 2030 using the Long-range Energy Alternative Planning System software alongside an assessment of sectoral energy usage. Findings indicate that adopting compressed natural gas across the transit fleet can substantially cut carbon dioxide output. In addition to vehicle fuel, flared gas holds potential for broader productive uses, including conversion to liquefied natural gas, liquefied petroleum gas, and electricity generation.
Gas flaring wastes valuable energy resources and harms local communities through air pollution and greenhouse gas emissions. Repurposing wasted gas into cleaner fuel for mass transit addresses environmental damage and urban pollution simultaneously. This approach shows how capturing industrial waste can support national decarbonisation targets while supplying clean, cost-effective energy for growing urban transportation networks.
The work focuses on industrial gas capture and alternative fuel supply for municipal mass transit, targeting fleet operators such as the Lagos Bus Rapid Transit system and energy infrastructure developers. By identifying conversion pathways into compressed natural gas, liquefied fuels, and power generation, it points to commercial gas-to-fuel initiatives. However, as the findings rely on predictive energy modelling, the application remains at an analytical and planning stage prior to operational deployment.

Globally, climate change and its adverse effects on the human population and the environment has necessitated significant research on the sustainable use of natural resources. Gas flaring in Nigeria’s oil and gas industry causes environmental and health hazards and to a large extent, culminates in yearly loss of the Nation’s revenue. The aim of the study is to highlight the potentials of converting flared gas from the Nigerian oil and gas industry to compressed natural gas (CNG) which could be an alternative fuel for the 220 Lagos Bus Rapid Transit (BRT-Lite) while reducing CO2 emissions. In addition, the study provided an overview of gas flaring in the oil and gas industry and energy utilisation in some selected sectors in the country. The Long-range Energy Alternative Planning System (LEAP) software was employed to model the energy demand and carbon dioxide emissions from the BRT-Lite by creating a current scenario and projections to the year 2030. The use of CNG as an alternative fuel for Lagos BRT-Lite will significantly reduce CO2 emissions in Nigeria’s oil and gas industry. Other utilization options for flared gas from this industry includes: Liquefied Natural Gas (LNG), Liquefied Petroleum Gas (LPG), and power generation.
