Energy outlooks for Africa feature increased use of fossil fuels. However, they widely ignore that a transition from traditional to modern bioenergy can support the increasing commercial energy demand and offer a high level of flexibility and dispatchability. We use energy statistics, resource assessments and demand analysis to show how switching traditional biomass use to more sustainable technologies could practically eliminate unsustainable fuelwood use. Furthermore, mobilising agricultural and forestry residue for commercial use could grow a sustainable biomass industry and offset Africa's projected expansion of fossil fuels. The assessment focuses on feedstocks and potential energy conversion options for selected and most promising bioenergy pathways in Sub-Saharan Africa's growing and economically relevant industries: cement, agricultural processing, livestock, and horticulture. Examples of specific applications are given to support the high-level resource assessment and demand balances in these sectors. Our results indicate that 3317 PJ bioenergy could be utilised in Sub-Saharan Africa. Even with the calculated gap between biomass availability and biomass demand of 5559 PJ in future energy scenarios, bioenergy can contribute to sustainable energy supply and access in SSA. The sustainability mapping highlighted that bioenergy could deliver integral social and economic impacts because of the close integration with agriculture as the main livelihood supporting sector in SSA. Sustainability frameworks and governance structures must consider bioenergy beyond its cost and clean energy potential to maximise positive trade-offs. • Residue-based bioenergy has potential for scaling up modern energy services in Africa. • Modern bioenergy can enable industries to prosper without compromising sustainability. • Industrial use of bioenergy can offset projected expansion of fossil fuels in Africa. • Bioenergy can deliver sustainability benefits beyond energy access and decarbonisation.
