Evaluating the Economic Viability of Decentralised Solar PV-based Green Hydrogen for Cooking in Ghana

Abstract

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