The project focuses on the utilization of solar thermal and electric energy to power the thermo-chemical conversion of carbon-based waste streams including residual biomass and municipal wastes (forest residues, kraft lignin, agro-biomass, used wood, etc.) for the production of Sustainable Aviation Fuels (SAF). The project will study options to reduce the European dependence on biomass imports for SAF production, enable the pro-cessing of mainly domestic carbon-based wastes and ensure stability and security of energy supply. The target is to build the world’s first energy system consisted of an innovative pilot-scale fast pyrolysis continuous reactor with groundbreaking conversion efficiency, heated by concentrated solar power, and supplied by clean hydrogen from a state-of-the-art electrolyzer powered by photovoltaic solar power. The developed system will have a high upscaling potential, excellent global efficiency, ultralow environmental impact, and the highest security. The pilot scale reactor will bring significant cost reductions (CAPEX and OPEX/toe) in aviation fuels production, increase conversion efficiency and highly reduce the environmental impact in the fuel production stage. The developed SAF will be investigated and characterised with respect to thermo-physical, mechanical and storage behavior, as well as with respect to its combustion performance to ensure excellent compatibility of produced SAF with the current fleet of aircrafts.
