IEA IETS Task 11: Industrial Biorefineries (Working period 2022-2024)

Biorefineries producing a portfolio of biobased products or bioenergy are the backbone of the growing bioeconomy. IEA IETS Task 11 aims to minimize greenhouse gas emissions to net zero along different biorefinery pathways. Tools and methodologies for increasing energy efficiency and the use of renewable energies are to be summarized and disseminated to relevant target groups.

Short Description

The main objective of IEA IETS Task 11 is to aim for widespread decarbonization of and by industrial biorefineries to achieve net zero or negative greenhouse gas emissions. Within this objective the following sub-goals will be pursued:

  • Objective 1: Establish a network and communication within the national and international consortium.
  • Objective 2: Elaboration of the state of research and research questions on negative/net-zero emissions in biorefineries to give an overview on
    - emerging technologies
    - tools and methodologies
    - biorefinery light-house projects
  • Objective 3: Dissemination of results to increase visibility.

The content of the Austrian activities relates specifically to the leadership and associated knowledge transfer within Subtask 6: Technology Pathways towards Negative and/or Net-Zero Emission Biorefineries. In an extensive network of research and industry, the current research landscape of technological pathways towards negative/net-zero emissions in biorefineries will be reviewed. In addition, existing tools and methodologies for increasing energy efficiency and renewable energy use are summarized. To demonstrate that opportunities for net-zero/negative emissions in industrial biorefineries are feasible, as well as to ensure and improve knowledge transfer, specific case studies (conceptual and demonstrated) in at least three different industrial sectors will be summarized.

As a result, a compendium entitled "Net-Zero/Negative Emission Pathways for Biorefineries" will be available at the end to provide an overview of the national and international research landscape.
