The goal of Task 1 within the entire project was the assessment of the deployment potential of RFNBOs and RCFs over the period from 2020 to 2050 in the EU transport sector. All relevant transport sub-sectors and modalities are considered: road transport, maritime and inland shipping, aviation, and railway. Furthermore, the competition for RFNBOs and RCFs between the transport sectors and other sectors and applications of RFNBOs is considered. A central result is the potential gross final consumption of RFNBOs and RCFs that would count towards the RES target in the transport sector. In addition, the needed resources and the arising costs for this deployment as well as the impacts on greenhouse gas emissions and local environments are analyzed. Finally, barriers to the deployment and options to overcome these are outlined.enAir transportEnergy consumptionEnvironmental protectionMaritime transportNatural gasRail transportReduction of gas emissionsRenewable energyRoad transportSubstitute fuelTransport infrastructurereport
