Renewable hydrogen economy outlook in Africa

Hydrogen presents an opportunity for Africa to not only decarbonise its own energy use and enable clean access all, but also export renewable energy. This paper developed a framework assessing resources hydrogen production provides new critical analysis as how what role can play in the complex African landscape. The regional solar, wind, CSP, bio potential ranges from 366 1311 Gt/year, 162 1782 463 2738 0.03 0.06 Gt/year respectively. water availability sensitivity results showed that shortages some countries be abated by importing regions with high resources. A techno-economic comparative indicated voltage direct current (HVDC) system most cost-effective transportation overall costs per kg of 0.038 $/kg, followed pipeline 0.084 seawater desalination 0.1 liquified tank truck 0.12 compressed 0.16 liquefied ammonia 0.38 0.60 0.77 $/kg. quantified significance economies scale due cost effectiveness systems such when is scaled up. Decentralization favorable under constraints, e.g., will more effective below 800 km 1400 lower investment operation costs. • has solar PV, CSP biomass production.
