Assessment of the Technical and Economic Performances of Biofuels, E-Fuels and E-Biofuels Processes

Short Introductive summary

In a context of energy transition, where the necessary electrification of applications will not be able to replace the entire demand for carbonaceous molecules, it is crucial that their production is decoupled from fossil carbon extraction. If it makes sense to use electricity for road mobility, especially for short distances, liquid or gaseous fuels should be more appropriate for longer distances, especially for aviation and shipping. Similarly, the replacement of liquid fuels in aviation by other fuels (gas, electricity) seems highly unlikely. For this reason, we need a focus and an overview of the performance of processes for the production of synthetic biofuels, synthetic e-biofuels or synthetic e-fuels. This study was designed to provide a clear view of the different existing conversion routes, their characteristics and performance. It was necessary to capitalise on the work done in the past. This study has provided new technical and economic assessment results for a wide range of thermochemical conversion processes for renewable carbon (more than 130 case studies).
