Developing countries, including Ghana, face challenges ensuring access to clean and reliable cooking fuels technologies. Traditional biomass sources mainly used in most developing countries for contribute deforestation indoor air pollution, necessitating a shift towards environmentally friendly alternatives. The study's primary objective is evaluate the economic viability of using solar PV-based green hydrogen as sustainable fuel Ghana. study adopted well-established equations investigate performance proposed system. findings revealed that levelized cost discounted cash flow approach about 89 %, 155 190 % more than electricity, liquefied petroleum gas (LPG), charcoal. This implies produced not cost-competitive compared LPG, charcoal, electricity. However, with sufficient capital subsidies lower upfront costs, analysis suggests could become an attractive alternative fuel. In addition, switching from firewood yields highest carbon dioxide (CO2) emissions savings across cities analysed. Likewise, replacing charcoal also offers substantial CO2 savings, though firewood. Correspondingly, LPG produces growing body knowledge on energy solutions, offering practical insights policymakers, researchers, industry stakeholders seeking promote adoption economies.
