Political Economy of Green Hydrogen Rollout: A Global Perspective
Dec 2021
Publication
The present paper dwells on the role of green hydrogen in the transition towards climateneutral economies and reviews the central challenges for its emancipation as an economically viable source of energy. The study shows that countries with a substantial share of renewables in the energy mix advanced natural gas pipeline infrastructure and an advanced level of technological and economic development have a comparative advantage for the wider utilization of hydrogen in their national energy systems. The central conclusion this review paper is that a green hydrogen rollout in the developed and oil-exporting developing and emerging countries is not a risk for the rest of the world in terms of the increasing technological disparities and conservation of underdevelopment and concomitant socio-economic problems of the Global South. The targets anchored in Paris Agreement but even more in the EU Green Deal and the European Hydrogen Strategy will necessitate a substantial rollout of RESs in developing countries and especially in the countries of the African Union because of the prioritization of the African continent within the energy cooperation frameworks of the EU Green Deal and the EU Hydrogen Strategy. Hence the green hydrogen rollout will bridge the energy transition between Europe and Africa on the one hand and climate and development targets on the other.
Evaluating the Economic Viability of Decentralised Solar PV-based Green Hydrogen for Cooking in Ghana
Jul 2024
Publication
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.
