Workshop: Development of torrefaction technologies and impacts on global bioenergy use and international bioenergy trade

28. January 2011
Stadthalle Graz
Graz, AT

The workshop is an integral part of the "Central European Biomass Conference 2011" and will give a comprehensive overview of fundamentals of torrefaction, the main advantages of and the challenges in producing torrefied biomass.

Organizer

  • IEA Bioenergy Task 32: "Biomass Combustion and Co-firing"
  • IEA Bioenergy Task 40: "Sustainable International Bioenergy Trade"

Content Description

Torrefaction is an interesting pre-treatment technology for biomass before pelletisation and/or combustion. It is a thermo-chemical process for the upgrading of biomass that is usually run at temperatures ranging from 200 to more than 300°C under the exclusion of oxygen and at ambient pressure.

This workshop will give a comprehensive overview of fundamentals of torrefaction, the main advantages of and the challenges in producing torrefied biomass. Ongoing R&D activities will be shown, demonstration plants under construction or already in operation will be presented and the latest state-of-science in torrefaction will be discussed.

A major focus of the workshop will also be put on logistic aspects of torrefied biomass and the possible impacts on global international bioenergy trade. International biomass trade of e.g. wood pellets, ethanol or biodiesel has been growing strongly in the past decade, but is still relatively small compared to other commodities. While the technical biomass potential would in theory allow for much larger quantities to be utilized, in practice the use is hampered by a geographical mismatch of supply and demand, and associated high logistical costs. Torrefaction is a pre-treatment technology that may help to overcome this barrier as it might enable the use of so-far unutilized biomass potentials, and may thus play a pivotal role for the future growth of bioenergy trade.
