Abstract: tBiomass is an important renewable energy source that holds large potential as feedstock for the produc-tion of different energy carriers in a context of sustainable development, peak oil and climate change.In developing countries, biomass already supplies the bulk of energy services and future use is expectedto increase with more efficient applications, such as the production of biogas and liquid biofuels forcooking, transportation and the generation of power. The aim of this study is to establish the amountof Ghana’s energy demand that can be satisfied by using the country’s crop residues, animal manure,logging residues and municipal waste. The study finds that the technical potential of bioenergy fromthese sources is 96 PJ in 2700 Mm3of biogas or 52 PJ in 2300 ML of cellulosic ethanol. The biogas poten-tial is sufficient to replace more than a quarter of Ghana’s present woodfuel use. If instead convertedto cellulosic ethanol, the estimated potential is seven times the estimated 336 ML of biofuels needed toachieve the projected 10% biofuels blends at the national level in 2020. Utilizing the calculated potentialsinvolves a large challenge in terms of infrastructure requirements, quantified to hundreds of thousandsof small-scale plants.
