Abstract In this project is studied a combined system that utilizes biomass to produce both electricity and methanol. A xed-bed gasier working on atmospheric pressure based on a existing unit at Gasication Group, MEK, DTU is used to produce the syngas. The power system is composed by a Solid Oxyde fuel cell (SOFC) working at 800C and a gas turbine (GT) using the remaining heat value of the FC exhaust. For the methanol production the syngas is compressed to 150 bar with a two-stage intercooled compressor.Heat for district heating (DH) is also produced. The eciency calculated for power production is 42,7%, and for mehtanol production 55%. The aim is to understand if a system capable of producing electricity when there is high demand, and methanol when the electricity price is low, is economical advantageous. The economic analysis done for both Danish and Italian markets shows that this is not realized. The results show anyway that a combined SOFC/GT system based on a gasier can be a promising technology.
