Systematic Literature Review of Hydrogen Production Technologies, Feedstocks and Pathways, and Its Prospects in Sub-Saharan Africa
摘要
This study aims to address the data gaps hindering the development of a hydrogen market in sub-Saharan Africa (SSA) by conducting a systematic literature review on hydrogen production technologies, feedstocks, and pathways. Through analysis, practical avenues for further research and development of hydrogen production in the region are identified, considering financial and environmental factors. After systematically screening four (4) databases (Google Scholar, Scopus, Science Direct and Springer) following the PRISMA Protocol, 62 articles meeting all inclusion criteria underwent full review and quantitative analysis. Results indicate that 80% of articles identified steam methane reforming (SMR) of natural gas as economically viable but environmentally polluting. Meanwhile, 60% favoured water electrolysis with renewable energy and 13% preferred biomass-derived hydrogen as the most environmentally friendly hydrogen production method. Given SSA's abundant solar and biomass resources, and taking environmental friendliness as a key parameter, the authors recommend exploring solar-powered electrolysis and biomass gasification for hydrogen production in the region. Additionally, developing regional and national hydrogen development strategies is crucial to outlining a roadmap, setting deployment targets, and engaging key stakeholders. These findings provide policymakers and investors with updated data on hydrogen technology, guiding future hydrogen initiatives in sub-Saharan Africa.
