Currently, the worldwide demand for fossil fuel is increasing rapidly while known resources are diminishing, particularly energy resources such as oil and natural gas. This situation, coupled with severe climate changes, has amplified the need for renewable energy alternatives. Biomass energy emerges as a promising solution owing to its availability and the technological advancements that support its efficient and low-emission utilization. In this context, coffee husk, a byproduct of coffee processing industries in Ethiopia, presents a viable opportunity for energy extraction through thermo-chemical conversion methods such as gasification. Notably, critical data regarding the thermo-chemical characteristics of coffee husk remains scarce in existing literature. This study aims to experimentally investigate the gasification of coffee husk in a bubbling fluidized bed gasifier, specifically focusing on performance parameters like tar content and gas composition. The results indicate that the tar produced during the gasification of coffee husk does not adversely affect the gasifier's operation, while the observed gas composition is favorable in comparison to wood pellets. Consequently, coffee husk is identified as a promising feedstock for fluidized bed gasification.
