Abstract
A system level modelling study on two combined heat and power (CHP) systems both based on biomass gasification. One system converts the product gas in a solid oxide fuel cell (SOFC) and the other in a combined SOFC and micro gas turbine (MGT) arrangement. An electrochemical model of the SOFC has been developed and calibrated against published data from Topsoe Fuel Cells A/S (TOFC) and Risø National
Laboratory. The modelled gasifier is based on an up scaled version of the demonstrated low tar gasifier, Viking, situated at the Technical University of Denmark. The MGT
utilizes the unconverted syngas from the SOFC to produce more power as well as pressurizing the SOFC bettering the electrical efficiency compared to operation with the SOFC alone - from η_el=36.4% to η_el=50.3%.
