Bioenergy Production Potential of Available Biomass Residue Resources in Ethiopia

Abstract

The study intends to present the bioenergy potential in Ethiopia using major sources of biomass generation. The study utilized data from secondary sources to generate the potential using the available biomass sources within the country. In order to determine the bioenergy potential, four residue biomass sources, including livestock manure, crop residues, forest residues, and municipal solid waste (MSW) from major cities, were considered. The Food and Agriculture Organization Corporate Statistical (FAOSTAT) Database as well as national and local reports were used to compile information on crops, forests, animals, and human populations. The potential of each source is estimated for 2020-21 as the base year. The total bioenergy potential of the country is estimated to be 2955 petajoule (PJ) per year, with 56.01% of it coming from forest residue, 28.29% from crop residue, 15.36% from livestock waste, and 0.33% from MSW. In addition, it is estimated that 819.7 terawatt hours (TWh) of electricity may be generated from all sources yearly. This is equivalent to around 8, 58, and 89 times Ethiopia’s total primary energy consumption, electricity production, and electricity net consumption in 2020, respectively. Results also demonstrated that the total potential (819.7 TWh·y−1) is roughly 56% greater than the forest residues’ potential alone (459 TWh·y−1). This implies that biomass resources might be crucial in assisting Ethiopia to fulfill its future energy needs. To fully realize the availability of biomass energy, the study suggests performing integrated development research, choosing the best feedstock and value chains for bioenergy, and creating a bioenergy database.
