IEA Bioenergy

The IEA Bioenergy is an organisation founded in 1978 by the International Energy Agency (IEA) with the aim of improving international cooperation and the exchange of information on bioenergy research. Members of the IEA Bioenergy working groups are scientists from OECD and non-OECD countries. In accordance with the current research focus areas in the field of bioenergy research, the IEA Bioenergy consists of various working groups (tasks) with work programmes of three years each. The thematic orientation of the working groups is coordinated by a steering committee (ExCo). In the triennium 2019 - 2021, the IEA Bioenergy comprises 11 tasks, in which about 200 people from different international institutes, universities and economic agencies work together. The DBFZ is currently represented with several scientists in five working groups (Tasks) of the IEA Bioenergy. Further information is available at:

Task 40 has published a paper with the collaboration of DBFZ colleagues Malgorzata Borchers, Alena Hahn and Daniela Thrän: "Deployment of BECCS/U value chains. Technological pathways, policy options and business models".

An introduction to the report was given on 16.06.2020 as a web seminar, which can be viewed at the following link:


A Task 34 brochure was published in August 2020: Direct Thermochemical Liquefaction of biomass - Characteristics, processes and technologies.

Based on current discussions, the IEA Bioenergy has prepared a short document that presents the most important facts about the use of forest biomass for climate protection.


Since Monday, 20.07.2020 there is a summary and extended report of the workshop "Roles of bioenergy technologies in energy system pathways towards a WB2/SDG world", available which took place on 25.11.2019 in Berlin.

The report and workshop was co-organized by Daniela Thrän. The workshop took place in the context of the Intertask project "The Role of Bioenergy in a WB2/SDG world", in which several tasks of the IEA Bioenergy work together.

A written version on the topic: "Drivers for Successful and Sustainable Biogas Projects": International Perspectives Report of a symposium held on March 26, 2020 is available from Task 37.​​​​

The Biofuture Platform, a multi-stakeholder initiative from twenty countries to take action against climate change and support sustainable development goals by promoting international coordination of a sustainable low-carbon bio-economy, announced the introduction of a set of voluntary principles.


Task 39 has published a Newsletter May 2020, in which Franziska Müller-Langer (DBFZ), Nicolaus Dahmen (KIT) and Gabriel Costa de Paiva (DBFZ) have written an article worth reading: "Biofuels Production and Consumption in Germany: Status, Advances and Challenges".

Task 37 - "Energy from Biogas"

Task 37 is an international working group dealing with the anaerobic digestion (AD) of biomass feedstocks, including agricultural residues (e.g. fertilisers and crop residues), energy crops, organically rich wastewater, the organic fraction of municipal waste (OFMSW) and organic industrial waste. The main interests are the production of biogas for direct use for heat and electricity, the upgrading of biogas to biomethane, the use of biogas/biomethane for electricity grid balancing and high quality digestate that can be used as organic fertiliser. Task 37 deals with the entire biogas production chain, from the collection and pre-treatment of raw materials, through biogas upgrading and the use of bio-fertiliser, to the sustainability of the process chain.

Task 39 - "Commercialising Conventional and Advanced Transport Biofuels from Biomass and Other Renewable Feedstocks"

Task 39 is a group of international experts working on the commercialisation of sustainable biofuels for transport. Bioenergy and biofuels are important components within the green energy portfolio of a country. While there are many renewable energy options for heat and power generation, biofuels are currently the only way to replace liquid fossil fuels such as gasoline, diesel and aviation fuels.

Task 40 - "Deployment of biobased value chains"

The IEA Bioenergy Task 40 (known in the triennium 2016-2018 as "Sustainable biomass markets and international bioenergy trade to support the biobased economy") was established in December 2003 under the Bioenergy Implementing Agreement of the International Energy Agency with the aim of supporting the development of sustainable international markets and international trade in biomass. With the current triennium 2019-2021 this focus has been extended. The focus of Task 40 is on the development and design of efficient and sustainable value chains to support the increased use of biomass for energy, but also for bio-based products, chemicals and materials, taking into account the food and feed markets, in a regional, national and international context. Topics such as bio-economy, new regional bio-energy markets, BECCS/U and renewable gases play an essential role in this context.

Task 44 - "Flexible Bioenergy and System Integration"

The task is based on the work done in IEA Bioenergy Task 41 special projects during 2016-17: Project 5: Bio-CCUS in climate change mitigation and extended use of biomass raw material, Project 6: Bioenergy in balancing the grid & providing storage options and Project 7: Bioenergy RES hybrids. As a common conclusion from these projects, bioenergy has some unique properties that can address many of the problems related to the rapid transition to a low-carbon energy system.

Task 45 - "Climate and sustainability effects of bioenergy within the broader bioeconomy"

Task 45 is a new working group within the IEA Bioenergy with its first triennium of activities in 2019-2021 with the aim of identifying and addressing critical issues related to climate and other sustainability effects of bioenergy and bio-based products and systems. The goal is to promote the sound development of bioenergy as an integral part of the overall bio-economy.
