摘　　要：With the lowest power access rate in the world(51.4%),Sub-Saharan Africa is experiencing a severe energy crisis.Many of the region’s countries report access rates of less than 20%.Even though Sub-Saharan Africa has the lowest global greenhouse gas emissions,the region still suffers from climate change,especially extreme droughts.Efforts to tackle these issues by implementing a macro-grid system that integrates natural gas and renewable energy resources have not been successful in reducing the adverse environmental effects and energy poverty.This study highlights research on the technological approaches used in hybrid hydrogen/natural gas in heavy-duty dual-fuel power plants,their benefits and drawbacks,and their economic viability.The goal of this is to suggest an improved and more reliable hub energy system for Sub-Saharan Africa.While all countries in Sub-Saharan Africa utilize natural gas plants,only 17%are involved in hydrogen production,and none have implemented hybrid methods for electrical energy generation.Studies using experimental and numerical analyses have shown that adding hydrogen to natural gas plants increases overall efficiency and lowers CO_(2) emissions.Furthermore,this research introduces an energy hub approach that incorporates carbon capture and power-to-X technologies,potentially improving efficiency by 42%.These strategies not only support environmental sustainability but also provide economic advantages by decreasing operational and financial losses in power plants.The results reveal a new pathway for the region’s transition to sustainable energy:identifying key locations for the technological and economic viability of hybrid hydrogen/natural gas power plants in Sub-Saharan Africa.
