  For fast-tracking climate change response, green hydrogen is key for
achieving greenhouse gas neutral energy systems. Especially Sub-Saharan Africa
can benefit from it enabling an increased access to clean energy through
utilizing its beneficial conditions for renewable energies. However, developing
green hydrogen strategies for Sub-Saharan Africa requires highly detailed and
consistent information ranging from technical, environmental, economic, and
social dimensions, which is currently lacking in literature. Therefore, this
paper provides a comprehensive novel approach embedding the required range of
disciplines to analyze green hydrogen cost-potentials in Sub-Saharan Africa.
This approach stretches from a dedicated land eligibility based on local
preferences, a location specific renewable energy simulation, locally derived
sustainable groundwater limitations under climate change, an optimization of
local hydrogen energy systems, and a socio-economic indicator-based impact
analysis. The capability of the approach is shown for case study regions in
Sub-Saharan Africa highlighting the need for a unified, interdisciplinary
approach.
