In addition to renewable electricity, the main renewable fuel production technologies available today include:
▪ the esterification/transesterification of biomass with an oil and fat content and/or residual and
waste materials for the production of FAME,
▪ the hydrotreatment of biomass with an oil and fat content or residual and waste materials for the
production of paraffinic fuel substitutes for diesel (HVO or HEFA) and kerosene (HEFA-SPK)
▪ the alcoholic fermentation of biomass with a sugar and starch content for the production of
bioethanol
▪ the anaerobic fermentation (digestion) of agricultural biomass, waste and residuals, and animal
excrements for the production of biomethane.
These technologies compete in part for the same resources. In particular, as production capacities of HVO/HEFA fuels increase, pressure on FAME plants will grow. Other technologies (e.g., fermentation of lignocellulosic biomass to bioethanol) already have a high level of technological maturity and are to some extent already available on a regional basis; however, they have not yet been fully able to establish
themselves on the market. Development is currently focusing on purely electricity-based technologies (power-to-X, e-fuels) and electricity- and biomass-based hybrid technologies (SynBioPTX). In principle, different approaches are conceivable here. While there is support for biobased pathways using PTX technology (for example, by incorporating electrolytically produced hydrogen in HEFA processes and
synthesis/refinery processes), concepts for using biogenic carbon (e.g., via biogenic carbon dioxide from bioethanol and biomethane plants) in PTX processes are also receiving attention. Which of these options will establish themselves on the market depends not only on regional conditions, but also to a large extent on the general conditions and price developments of renewable energies in the transport sector.
