IEA IETS Task 11: Industry-based Biorefineries Towards Sustainability (Working Period 2024-2026)

In the IEA IETS Task 11, international efforts are being coordinated to advance technologies for industrial biorefineries aimed at comprehensive decarbonization, specifically targeting net-zero or even negative greenhouse gas emissions. Building on previous project phases, the following objectives have been defined for the Austrian contribution:

• Objective 1: Expanding the network and strengthening communication within the national and international consortium
• Objective 2: Developing an overview of the state of research on net-zero or negative emissions in biorefineries, focusing on:
  - Emerging biorefinery technologies
  - Bio-CCU/CCS technologies and concepts
  - Case studies and evaluation methods.
• Objective 3: Disseminating insights to support technological advancements and their implementation.

These efforts are integrated into the international research initiative as Subtask 2 "Technology Pathways towards Negative and/or Net-Zero Emission Biorefineries". An expert network of partners from research and industry is leveraged to bring together a broad range of approaches and findings to identify potential synergies and disseminate key insights. Emphasis is placed on highly energy-efficient, innovative technologies for process management in biorefineries, as well as on strategies for carbon capture and utilization (CCU) and carbon storage (CCS) from biogenic sources, supported by specific case studies and evaluations.

As a central outcome of this project period, the compendium "Pathways Towards Net-Zero/Negative Emission Biorefineries" will be developed and systematically expanded to consolidate insights from both international and Austrian activities, making them accessible to users.
