Techno-Economic Feasibility of Animal Waste for Electricity Generation: A Case Study of Tunisia

Climate change is the most urgent challenge of the 21st century and requires immediate action. Tunisia, like many other countries, is committed to decarbonizing its energy mix under the Paris Agreement, mainly by integrating 35% installed renewable energy capacity into the energy mix by 2030 with 100 MW from biomass. This paper aims to map animal manure potential in Tunisia and assess the highest possible electricity production with overall cost estimation. A model is developed using OSeMOSYS to evaluate the techno-economic feasibility of implementing manure-based biogas plants in Tunisia. The model results show that an electricity production of 450 GWh/year can be achieved by 2030 while allowing approximately 1489 KTons of manure to be processed. The lowest LCOE across all regions is 0.14 USD/kWh.
