In the heart of West Africa, a quiet revolution is brewing, one that could reshape the region’s energy landscape and position it as a key player in the global green hydrogen market. A recent study published in the journal ‘Vodík’ (translated from Czech as ‘Hydrogen’) sheds light on the techno-economic feasibility of green hydrogen production in five West African countries: Ghana, Nigeria, Mali, Niger, and Senegal. The research, led by Kokoutse Gawou from the Department of Materials Science and Bioengineering at Nagaoka University of Technology in Japan, offers a compelling narrative of opportunity and challenge.
Green hydrogen, produced by splitting water into hydrogen and oxygen using renewable energy, is gaining traction as a clean energy solution. With abundant solar resources and a pressing need to reduce carbon emissions, West Africa is uniquely positioned to harness this opportunity. “Green hydrogen offers a pathway to achieve multiple Sustainable Development Goals,” Gawou explains. “It’s not just about mitigating climate change; it’s about fostering economic development and energy access.”
The study evaluates the region’s solar energy potential, hydrogen production capacities, and economic viability using metrics like the Levelised Cost of Hydrogen (LCOH) and Net Present Value (NPV). The results are promising, with substantial annual hydrogen production potential and LCOH values competitive with global benchmarks. This is particularly significant in the context of the European Union’s Carbon Border Adjustment Mechanism (CBAM), which aims to reduce carbon leakage by imposing costs on carbon-intensive goods.
However, the path is not without obstacles. High initial capital costs, policy and regulatory gaps, limited technical capacity, and water resource constraints pose significant challenges. “We need targeted strategies to address these barriers,” Gawou emphasizes. “This includes strengthening policy frameworks, fostering international partnerships, enhancing regional infrastructure integration, and investing in capacity-building initiatives.”
The commercial implications for the energy sector are profound. Green hydrogen could diversify energy mixes, reduce dependency on fossil fuels, and create new economic opportunities. It could also position West Africa as a key player in the global green hydrogen market, attracting investment and fostering regional cooperation.
As the world grapples with the urgent need to transition to clean energy, this research offers a roadmap for West Africa to leverage its natural resources and strategic position. It’s a story of potential, of challenges overcome, and of a region poised to make a significant impact on the global stage. The journey is just beginning, but the destination is clear: a greener, more sustainable future powered by green hydrogen.
