IEA Bioenergy Task 32 – Biomass Combustion

EU | September 2016 - March 2025

IEA Bioenergy Task 32 is an international forum for discussing and sharing knowledge on biomass combustion and cofiring. Representatives from Austria, Germany, Switzerland, the Netherlands, Norway, Sweden, Japan, Canada, and Denmark participate, and through the cooperation biannual meetings are held, typically along with a workshop on a technical subject.

The objective of the Danish participation is to communicate results from the Danish RD&D projects about biomass combustion and cofiring, as well as collecting knowledge from the activities in other countries and communicating these to the Danish network.

For the past three-year period, 2019-2021, Task 32 had the following areas of interest and projects scheduled

Small plants – stoves and boilers

  • Testing methods and real-life performances of wood pellet stoves
  • Technical guideline for design of low emission stoves
  • Internal workshop on national strategies for reducing emissions from residential and commercial wood combustion
  • Open workshop on improved combustion in stoves and small biomass boilers


  • High temperature heating for the industry – cooperation with other IEA Bioenergy tasks


  • Flexibility and integration – input for Task 44
  • Open workshop about experiences with dust combustion of pulverised non-woody solid biofuels
  • Open workshop about experiences with wood chip combustion in large scale CHP plants

Ea represents Denmark in Task 32

Denmark took over the leadership of Task 32 from the Netherlands for the period 2019-2021, and continues to lead the task in 2022-2024.

Ea Energy Analyses oversees this, with the Danish Energy Agency as the Operating Agent. Additionally, Ea Energy Analyses is the Danish representative in Task 32. This work is jointly financed by EUDP and Ea Energy Analyses and is a continuation of the work of the previous years.

We regularly send out a Danish newsletter on the work of the task. If you wish to receive this, please write an email to Morten Tony Hansen at Previous newsletters can be downloaded on this page.

Task 32 has its own website, which can be found here. It contains alle the reports of the group, as well as information about previous workshops.

Ea Energy Analyses studied the future of thermal biomass plants in the power systems as a part of Task 32 in 2018. The results of the study was presented in form of a Technical Report by IEA Bioenergy Task 32 and at the IEA Bioenergy conference in San Francisco November 2018. The report can be downloaded on this page.
