In the IEA Bioenergy Tasks 22 the objectives were:
· to conduct analysis of bioenergy systems to support
organisations working with products and services related
· to build and maintain a network for R&D organisations
· to disseminate data on biomass conversion technologies.
The IEA Bioenergy techno-economic resources have been
maintained and improved since original studies in 1982.
State-of-the-art, performance, and feasibility analysis
of biomass to
· (heat and) electricity (CHP)
· liquid, gaseous, and solid fuel systems
· chemicals from biomass
have been carried out.
Technical and economic feasibility studies were carried
out for several biomass power and fuel conversion
technologies in Austria, Canada, Finland, Sweden and the
United States during 1998-1999. Brazil was also a
participant in the task. The core technologies analysed
· a flue gas condensing system for increased heat
production integrated to a biomass boiler
· the production of slow release fertilizers from fast
· small-scale steam boiler power plant compared to new
· fast pyrolysis liquid production for district heat
production within a city, and
· small modular biomass power systems.
Performance (mass and energy balances) of systems are
determined rigorously, and the economic assessment will
be carried out with companies supplying or planning to
use these systems. The companies, whose technologies or
sites are considered, have been selected by the funding
agencies in the countries participating in this task.
The participants have found the results of the first one
and half years valuable, and have agreed to continue the
task during the year 2000. Additional cases will be
analysed during year 2000. The collaboration has proved
to be a cost effective way to generate necessary
techno-economic base data to be used in supporting
decision making in R&D.
