Abstract
This deliverable was developed to identify best practices and forward-looking concepts that can accelerate the scale-up of sustainable aviation fuels (SAF) in Europe and beyond. The work combines evidence generated through literature reviews, techno-economic, environmental and social sustainability assessments developed in other work packages in the ICARUS project, sixteen in-depth stakeholder interviews, three international co-creation webinars, and a large multi-stakeholder workshop organized during the 34th European Biomass Conference & Exhibition (EUBCE 2026).
Together, these activities provide a comprehensive understanding of the opportunities, limitations, and future development needs of the three selected SAF value chains of ICARUS: biocrude oils to SAF, syngas to SAF, and alcohols to SAF. While the assessments provided quantitative and analytical insights, the extensive stakeholder engagement activities helped validate findings, identify practical deployment challenges, and capture lessons learned from industrial experience. Despite differences in geographical context, organizational background, and technological focus, a remarkable degree of convergence emerged across all stakeholder engagement activities. While each value chain presents its own technological characteristics and development needs, common themes appeared throughout the interviews, webinars, workshop discussions, as well as supporting assessments.
