IEA Bioenergy Task 33: Gasification of Biomass and Waste (Working Period 2019 - 2021)

The main aim of IEA Bioenergy Task 33 is the international as well as national information exchange and networking on thermochemical gasification of biomass and waste. The focus is on exchange of information regarding R&D programmes in area of biomass and waste materials gasification, commercial facilities and the marketing chance for gasification facilities to identify and avoid technical and non-technical hurdles.

Short Description

Austria is since 1978 member of the Bioenergy Implementing Agreement of the IEA. The aim of Task 33 „ Gasification of Biomass and Waste" is to exchange information on the utilization of product gases from thermal biomass gasification to produce heat, electricity, chemicals and fuels. Especially the information exchange about R&D programs in the area of biomass gasification, about commercial plants and about possible markets is taken into account, to remove technical and non-technical barriers for the market introduction of biomass gasification.

As everything in the world, also the Task activities were influenced by pandemic Covid-19. Nevertheless, the information exchange was kept and enabled, the Task meetings were online and instead of workshops, webinars were organized.

In addition to meetings and workshops, IEA Bioenergy Task 33 works on different topics regarding the gasification, those themes are handeled in frame of special Task projects.

The aim of each special Task project is a publication, which informs about the gasification, operational practice, status and developments. The topics for special Task projects are chosen based on actual situation as well as important topics regarding the gasification implementation (e.g. circular economy), as well as potential cooperation with other Tasks.

During the last triennium, following special Task projects were finished and on the Task 33 website published:

  1. Status report on gasification of biomass and waste – Research special
  2. Gasification applications in existing infrastructures for production of sustainable value-added products
  3. Emerging gasification technologies for waste and biomass

The website of IEA Bioenergy Task 33, which is managed by BOKU Vienna, is the most important tool for the information dissemination. On the national level, the attention is given to exchange of information regarding national employment of gasification.

For the stakeholders from Austria, Germany and Swiss, two International conferences on applications of gasification were organized in 2019 and 2021 (because of Covid in online version). The aim of the conference is to offer a platform for networking and exchange of information. The conference is organized especially for appliers of gasification technologies, thus also the presentation language is German.

The Austrian stakeholders were as usual, twice per year informed about the Task activities through a newsletter in German language, as well through the IEA Bioenergy newsletter. Additionally, BOKU is in close contact with other Austrian research institutions (BEST, TU Wien, MCI, JKU,...) and companies.

In the last triennium following issues were worked out:

  • 6 Task meetings were organized, where each member country presented the national status of gasification in form of ppt (update)
  • Each triennium, the written Country report had been published on the website.
  • Studies were carried out, as well special Task projects, Task meetings and webinars
  • Task website and database were updated regularly
  • IEA Bioenergy international and national newsletter
