FUEL-UP aims at transforming 100% biogenic waste into advanced biofuels to enable the green transition and the decarbonisation of the aviation and the marine transport sectors. FUEL-UP will provide solutions to make a paradigm shift towards the production of renewable sustainable aviation and marine fuels by producing stabilized deoxygenated pyrolysis oils from pyrolysis oils derived from 100% biogenic feedstock that can be subsequently processed towards a fully hydrotreated oil in a refinery. The project will, therefore, validate, at demo scale, a route to produce sustainable liquid biofuels from lignocellulosic streams with 45-50% aviation fuel, 30-35% in the marine diesel range and 20% heavy naphtha at TRL-7.
