“…Nigeria also has great potentials for relatively clean fuels like compressed natural gas (CNG) 33 - 35 and biofuels/biodesiel 36 - 38 ; this is also a plus to the decarbonisation agenda. Investment into research and development can help Nigeria exploit her renewable energy potentials.…”

“…Thus, policy incentives that can expedite the adoption of zero emission vehicles by the Nigerian community are non-existent. Meanwhile, irrespective of the apparent low response to decarbonisation of the Nigerian transport sector, there abound a great potential for decarbonisation to thrive in Nigeria owing Nigeria also has great potentials for relatively clean fuels like compressed natural gas (CNG) [33][34][35] and biofuels/biodesiel [36][37][38] ; this is also a plus to the decarbonisation agenda. Investment into research and development can help Nigeria exploit her renewable energy potentials.…”

We reviewed the various sub-sectors of the Nigerian transport sector with their corresponding energy consumption rates. Results show that all the sub-sectors are solely dependent on fossil fuels to meet their energy demands and requirements, thus making the transport sector the highest consumer of fossil fuels, and consequently, the highest contributor to carbon footprint. This necessitates the need for gradual decarbonisation of the sector, but not at the expense of the nation’s economy, since the transport sector contributes about 3% of the nation’s GDP. We have therefore outlined measures to decarbonise the sector. These include revitalisation of the rail and water transport; encouragement of mass transit; improving the state of security on Nigerian roads; employment of low-carbon fuels (biodiesels); and use of electric vehicles.

“…Diesel fuel's ability to self-ignite and natural gas' low rate of pollution are combined to create an intriguing power to pollution ratio. Numerous studies on the creation, fabrication, and modelling of dual-fuel engines have been published [10][11][12]. Different engine manufacturers have incorporated dual-fuel technology into a variety of products (cars, power plants) as a whole or as an added feature.…”

Studies from around the world show that engines using biofuel, LPG, and CNG emit fewer pollutants than those using conventional fuels. Experimental research has focused on a rapid compression and expansion machine (RCEM) that resembles a compression ignition (CI) engine. It uses dual direct injection fuel, diesel and propane (DP), with propane injection timing varying from 0 to 40 before top dead center (BTDC) and diesel injection timing remaining at 10 BTDC. The compression ratio was changed at points 17 and 19 by adjusting the RCEM connecting rod. A converge simulation program was used to run the simulation model, which was used to examine how the fire and inflow inside the chamber developed. The ANN method was used to predict pressure, temperature, power, TKE, and ITE data output based on propane energy fraction, compression ratio, and SOI of propane as input data parameters. It was noticed that the ANN prediction on experimental data has a higher accuracy compared to the simulation prediction. The R and MSE values were used to identify the accuracy of the prediction on output parameter data. ANN generalization capability is comparatively high when trained with large enough databases. The highest accuracy of prediction was produced on TKE, which had an MSE of 0.003715 and R value of 0.99981 from 287900 sample data. This shows that the ANN model is quite accurate in forecasting output experimental data.

In an attempt to address major causes of pollution from gas flaring and transportation, the Nigerian government introduced the use of CNG (compressed natural gas) as an alternative fuel for automobiles in 1997. However, progress has been very slow as the government has concentrated more on LNG (liquefied natural gas) exportation, LPG (liquefied petroleum gas), and gas to power projects. These projects have aided in reducing gas flaring, but pollution from transportation is still increasing. This article provides an extensive review of the benefits and recommendations to foster the use of CNG as an alternative fuel for automobiles in Nigeria. The use of CNG as an alternative fuel for automobiles in Nigeria has benefits ranging from reduction in pollution to an increase in productivity, efficiency, safety, and energy security. Thus, to encourage the use of CNG as automobile fuel in Nigeria, the government needs to develop a targeted carbon tax system, favourable market-based policies and natural gas transmission and distribution network; increase availability and access to CNG refuelling stations and public awareness; subsidise vehicle conversion expenses; begin with bi-fuel/dual-fuel automobiles; assign responsibilities; reform gas pricing; partner with automobile producers in Nigeria.
