The present paper reports on a demonstration project supported by the THERMIE program of the European Commission and by the VLIET program of the Flemish Government. A CHP gas turbine plant fueled by product gas from a biomass fluidized bed gasifier has been constructed. The demonstration scale is 500 kWe for production of power and heat for the university campus district heating. At the present stage 150 kW power has been delivered to the grid. Problems encountered and results achieved during the first startups of the power plant will be discussed. In the future some natural gas topping combustion will be included to overcome the temperature limitation of materials used in the metallic high temperature air heater. Water injection in this air heater will be included to enhance power output and to allow flexible power to heat ratios. The target commercial scale is 2 to 5 Mwe using atmospheric gasification and external firing through a high temperature metallic heater.
