2nd World Conference and Exhibition on Biomass for Energy, Industry and Climate Protection

Workshop 4: 

Biomass cofiring - Current trends and future Challenges

Chairpersons: Sjaak van Loo, Bill Livingston

Cofiring biomass with coal is becoming increasingly popular around the globe for various reasons. It is often found to be a relatively low-cost measure for large-scale renewable energy generation. Depending on the specifications of biofuels to be cofired, various configurations exist, varying from directly mixing biofuel with coal and joint firing, pre-gasification and parallel firing. However, there are several barriers that hinder actual implementation, such as uncertainty about the legal and political environment, liberalization of the energy sector, as well as uncertainties about long term fuel supplies at low costs. Another issue is the utilization of fly-ashes, which is often not allowed if the ash is partly from biomass origin
