“…The use of animal manure for energy generation, and in particular as feedstock for anaerobic digestor technology, has received extensive coverage in both the research and review literature globally as well as in the sub-Saharan Africa (SSA) context. The vast majority of this research, however, is focussed on anaerobic digestor-process improvement [17], in particular on feedstock choices for increased biogas output [18][19][20], bioreactor design and diagnosis of bioreactor failures [21], impacts of private-public partnerships on biogas technology development [22], and socio-economic barriers to technology adoption [23,24]. In so doing, lab-scale successes and achievements are often misconstrued for on-the-ground implementation success whereas, in practicality, there is a disconnect between research and implementation [25].…”

Energy availability is a pivotal driver in fostering sustainable socio-economic development. However, sub-Saharan Africa (SSA) grapples with paradoxes headlined by abundant energy resources but with the world’s lowest access to clean energy index per capita. Faced with a lack of access to clean energy sources like electricity, rural areas in the majority of SSA countries almost exclusively depend on biomass-fuels, mostly fuelwood, leading to heightened respiratory health risks as well as environmental degradation and accelerated climate change. As an alternative, this review investigates the potential of animal manure as a sustainable energy resource for rural SSA households, emphasising its utilisation as a feedstock for biogas production using anaerobic digestor technology. Results show that despite the abundance of literature that reports on successes in lab-scale bioreactor optimisation, as well as successes in the initial rollout of biogas biodigester technology in SSA with the help of international collaborators, the actual uptake of biogas bioreactor technology by rural communities remains low, while installed bioreactors are experiencing high failure rates. Resultantly, rural SSA still lags significantly behind in the adoption of sustainable clean energy systems in comparison to rural communities in other regions. Among some of the hurdles identified as driving low technology assimilation are onerous policy requirements, low-level government involvement, high bioreactor-instalment costs, the lack of training and awareness, and water scarcity. Prospects for success lie in innovative technologies like the low-cost portable FlexiBiogas system and private–public partnerships, as well as flexible energy policy frameworks. Bridging the knowledge-implementation gap requires a holistic approach considering cultural, technological, and policy aspects.

Understanding the potential of biomass sources and their types, quality, and regional distribution is crucial for modern energy production. This study evaluates the biomethane energy potential of livestock waste from six different categories of livestock across all Ethiopian regions using livestock statistics (2020–21), standard procedures, publicly accessible data, and literature. To evaluate the bioenergy potentials, the amount of dry matter per head, collection efficiency, biogas yields of respective livestock waste, and the calorific value of biogas and biomethane were used. The total biomethane and corresponding bioenergy potential of livestock residues in Ethiopia are estimated to be 3,321 hm3 y-1 and 118,906 TJ y-1, respectively. The biomethane combustion in a combined heat and power system is expected to produce roughly 11.4 TWh y-1 of electricity and 13.9 TWh y-1 of thermal energy. The estimated electrical energy could supply 11%, 31%, and 81% of Ethiopia’s total primary energy consumption, production, and total electricity generated in Ethiopia in 2019, respectively. The finding demonstrates that biomethane-based energy production via anaerobic digestion based on livestock waste has the potential to meet a significant portion of Ethiopia’s current energy needs.
