The bioliq® project at KIT demonstrated early on how residual biomass such as straw can be converted into synthetic fuel - a technological milestone that is also highly relevant for the InnoFuels platform project. The process chain comprises the shredding and drying of residual biomass, its thermochemical conversion via fast pyrolysis, the central gasification and purification of the synthesis gas and the subsequent chemical fuel synthesis. And all of this on an industrial scale. In this interview, project manager Prof. Nicolaus Dahmen looks back on the most important stages, challenges and successes of bioliq ®.

A new technical report from ISP Road&Rail summarizes how paraffinic diesel - especially HVO - affects the particle mass and particle number emissions of diesel engines. Both internal engine emissions and the effect of exhaust gas aftertreatment systems are taken into account. The paper provides important findings on engine and aftertreatment emissions and can thus support fleet operators, manufacturers and politicians in using the fuel, which has been officially approved since mid-2024, sensibly and responsibly as a climate-friendly option.

At a workshop in mid-February, the focus this time was on scenarios for the market ramp-up of e-fuels in road transportation. Our project partner, Frontier Economics, had analyzed and evaluated studies from several institutes in detail on behalf of an association. The results provide valuable insights into the expected price development of a fuel mix of fossil and green gasoline and diesel in the coming decades - a crucial basis for planning the market ramp-up. The subsequent discussion based on the diverse experiences of the InnoFuels partners once again provided new impetus.
