IEA Bioenergy Task 39: Commercialising Conventional and Advanced Transport Biofuels from Biomass and Other Renewable Feedstocks (Working period 2022 - 2024)

The overall goal of Task 39 is to facilitate the commercialization of biogenic, sustainable, low-carbon transportation fuels. This includes conventional and advanced biofuels produced through various technological routes such as oleochemical, biochemical, thermochemical, and hybrid conversion technologies. The main goal is to accelerate the decarbonization of the transportation sector, with an increasing focus on long-distance transport, which is more difficult to electrify.

Short Description

Reducing greenhouse gas emissions from the transport sector is a goal of national and international climate and energy policy, but is particularly difficult to achieve compared to other sectors. Biofuels are already making a significant contribution here, immediately reducing emissions from the existing vehicle fleet. Developing technologies to produce advanced biofuels from biomass and residues should enable expanded production and increased GHG emission savings in the transportation sector.

Through a coordinated focus on technology and commercialization, sustainability, policy, markets, and implementation, Task 39 will support its member countries and other transportation biofuels stakeholders in their efforts to develop and deploy sustainable, low-carbon biofuels in the transportation sector. The focus will remain on the decarbonization of the long-distance transportation sector (i.e., shipping, aviation, rail, and trucking). As in previous years, the Task will conduct comparative technological assessments and life-cycle analyses, and monitor the development of policy measures used (with varying degrees of effectiveness) to increase the production and use of biofuels to decarbonize transportation. A new addition to the work program is the participation in an IEA Bioenergy Inter-Task-Project (ITP) on the production and use of green hydrogen. The Task participants bring their expertise and the results of projects from their countries to the Task 39 studies, thereby enabling high-quality results with little resources.

The goal of the national work is to collect and analyze scientifically robust information on the global technological and policy status of biofuels, engage Austrian stakeholders and their work in the development, and thereby contribute to the development of sustainable, socially and environmentally sound biofuel systems. The Austrian delegate acts as an interface between the Austrian stakeholders and the international network.

The main outcomes of the work will be the active exchange of information with the Austrian stakeholders, the input of results into the task work, the dissemination of task deliverables, a national workshop on biofuels and a publishable final report.
