1 International workshop Torrefaction of biomass Introduction Jaap Koppejan Task leader, IEA Bioenergy Task 32: Biomass Combustion and Cofiring Martin Junginger Task leader, IEA Bioenergy Task 40: Sustainable International Bioenergy Trade Daniella Thrän Coordinator, SECTOR project Organised by Task 32: Biomass Combustion and Cofiring Task 40: Sustainable International Bioenergy Trade wwww.sector-project.eu

2 Torrefaction is like roasting coffee. Heating biomass to C in absence of oxygen Drying + removal of part of the volatiles roasting

3 Claims made. Brittle instead of tenacious Hydrophobic instead of hydrophyllic More energy dense And therefore Cheaper in logistics Unlocking remote biomass resources Lower capex of plant modifications for cofiring

4 Main technical challenges? flexibility in producing different product qualities, product quality control, heat integration, flexibility in using different input materials process emissions, process upscaling

5 Other open questions water uptake (seasonal aspects) dust & HSE (co)-milling capacities of auxiliary equipment reactivity and ignition behavior combustion heat release and flame impingement effect on boiler efficiency and carbon on ash slagging, fouling, corrosion effect on emissions and flue gas cleaning ash quality
