A recent report from IEA Bioenergy Task 39 highlights the crucial role of advanced biofuels in reducing CO₂ emissions in the transport sector. The report, entitled “Monitoring the deployment of advanced biofuel demonstration facilities”, provides a comprehensive overview of the development and deployment of advanced biofuel facilities worldwide.
Key findings:
- Diversity of technologies: The most advanced technologies for biofuel production are hydrotreating of oils and fatty acids, fermentation to cellulosic ethanol, gasification followed by Fischer-Tropsch synthesis and fast pyrolysis. Hydrotreating in particular is the most commercially developed and plays a key role in the production of sustainable aviation fuels.
- Importance of raw materials: The availability of feedstock is essential for the upscaling of biofuels. Although oily residues such as used cooking oil are valuable, their limited availability is a challenge. Unlocking the potential of biomass residues, such as agricultural waste and forestry by-products, is therefore of great importance.
- Scaling challenges: Scaling up advanced biofuel production requires international collaboration and knowledge sharing. Demonstration and scale-up are crucial to reach the production volumes needed to meet global decarbonisation goals, especially in hard-to-electrify sectors such as aviation and heavy transport.
The report also highlights the advantages of advanced biofuels, such as the diversity of technologies and feedstocks, the possibility of integration into existing infrastructure and their high energy density. Demonstration, scale-up and capacity building are essential for successful commercialisation, supported by long-term policies and comprehensive strategies.
Positive developments include growing demand and production in emerging economies and the decline of fossil fuels in long-haul transport sectors. The full report is available on the website of IEA Bioenergy.
