Biogas Plant is located in Busan, Korea and it has a facility to produce biogas through the anaerobic digestion of sewage sludge and food waste. But the generated biogas is recovered and used as fuel to increase the temperature in the digester and the rest is burned and dumped at the waste gas incinerator. In this study, we analyzed the performance of a biogas-fueled solid oxide fuel cell (SOFC) system, which is coupled with a Micro gas turbine (MGT) for a target biogas plant. The objective of this study is to clarify the relationship between the scale of a plant and the optimal size. The calculation results of the greenhouse gas emission due to power usage using biogas is decreased.
