Cost-benefit analysis of using hydrogen energy in african aviation industry

Hydrogen has proven to be a suitable alternative fuel for reducing the climate impact of aviation. This paper focuses on the cost-benefit study of the use of hydrogen energy in the African aviation industry. It discusses the cost-benefit of using hydrogen turbines and hydrogen fuel cells in Africa from 2024 to 2100. It uses the Global Warming Potential (GWP) method to convert CH4 and N2O into CO2-equivalent to predict emissions from African airlines. In addition, this paper also calculates the number of subsidies for hydrogen energy use in African aviation under ten scenarios from 2024 to 2100. The result shows that 2100 hydrogen energy can reduce African aviation emissions by 415.6 million tons to 735.4 million tons of CO2-equivalent. It is worth noting that no matter what the scenario is, the African aviation industry will use hydrogen turbines only when the carbon trading price is more significant than 0.24 times the price difference between hydrogen energy and aviation kerosene. And for hydrogen fuel cells, this value is 0.213 times.
