The Africa’s Extraordinary Green Hydrogen Potential study, conducted by the African Union, European Investment Bank, and International Solar Alliance, highlights the immense possibilities of green hydrogen in Africa. By leveraging the continent's solar energy potential, green hydrogen production could lead to substantial economic benefits, emission reductions, and advancements in various sectors. The study projects a €1-trillion investment opportunity and the avoidance of 500 million tonnes of CO2 emissions annually through green hydrogen production. Creating 50Mt of green hydrogen yearly not only stimulates the economy but also facilitates decarbonisation of industries, enhances energy access, and generates job opportunities. The article delves into the applications of hydrogen in different sectors across Africa. In transportation, hydrogen fuel cells offer a cleaner alternative for heavy-duty vehicles, public transport, and private cars, contributing to reduced air pollution and climate change mitigation. The power generation sector can benefit from hydrogen in energy storage, grid balancing, and clean electricity production. Industries like mining and manufacturing can transition to more sustainable practices by incorporating hydrogen in their processes, thus reducing emissions and enhancing energy efficiency. Moreover, hydrogen plays a crucial role in rural electrification efforts, providing off-grid communities with a reliable and sustainable energy source through microgrids. Africa's potential as a hydrogen exporter is also highlighted, with green hydrogen being a valuable commodity for ammonia production and clean energy export. However, realizing these benefits requires overcoming challenges. The study emphasizes the importance of national planning, pilot projects, and market partnerships to scale up green hydrogen production in Africa. By addressing these challenges and capitalizing on the diverse applications of hydrogen, Africa can unlock its green hydrogen potential for sustainable development and economic growth.
