Abstract
The removal of fuel subsidies in Nigeria has heightened energy and transportation costs, intensifying
inflationary pressures and economic instability. To address this, adopting alternative fuels particularly
Compressed Natural Gas (CNG) and Compressed Biomethane Gas (CBG) offers a pathway toward
energy diversification and resilience. This review systematically synthesizes academic and technical
literature, including 45 studies published between 2010 and 2024, to assess the safety, environmental,
economic, and energy security implications of transitioning from petroleum fuels to CNG and CBG.
Findings reveal that while CBG provides superior environmental benefits and long-term
sustainability, CNG remains more cost-effective for short-term implementation. The study identifies
policy, infrastructure, and technological gaps limiting adoption and concludes with targeted
recommendations to guide Nigeria’s sustainable energy transition strategy
Description
The adoption of Compressed Natural Gas (CNG) and Compressed Biomethane Gas (CBG) as
alternative energy carriers in the energy and transportation sectors has garnered increasing scholarly
and industrial interest globally, driven by their potential for improved fuel availability, costeffectiveness, enhanced energy efficiency, and significant reductions in pollutant emissions (1-2).
Both CNG and CBG are compressed gaseous fuels utilized in internal combustion engines, offering
distinct environmental and performance advantages compared to conventional gasoline and diesel
fuels. CNG, primarily composed of methane with minor fractions of other hydrocarbons (3), is
typically sourced from subterranean natural gas reserves or as a byproduct of petroleum extraction,
requiring compression to high pressures (200-250 bar) for efficient storage and transportation
