- For the first time, large quantities of synthetic diesel and gasoline fuel have been produced from renewable energy.
- The technology for producing the reFuels products has been refined and further developed and their carbon and energy efficiency significantly increased.
- In addition, the developed fuels were tested in vehicles with today's combustion engines. A haulage company in southern Germany drove over a million test kilometers with a fleet of different types of trucks using the reFuels fuel.
- In order to enable larger-scale production and the market launch of reFuels, a concept for a demonstration plant on a refinery scale was developed.
- Finally, the quotas for blending into conventional fossil fuels were increased to 100 percent, resulting in a "reFuels pure fuel".
- All relevant factors, from production processes to costs and product properties through to environmental influences, were evaluated holistically for the first time.
- Discussion events and workshops were held to inform all interest groups, from industry to trade associations, politics, NGOS and consumers, thus involving them in the research process.

Can renewable fuels - so-called reFuels - become a game changer in the fight against climate change? And how can they be produced efficiently and cost-effectively? The Karlsruhe Institute of Technology (KIT) has been researching this for several years together with partners from industry, politics and science. In 2019, the research initiative "reFuels - Rethinking Fuels" was created under the umbrella of the Strategy Dialogue Automotive Industry of the State of Baden-Württemberg (SDA). For two and a half years, research was conducted along the entire value chain: from energy suppliers and fuel production to suppliers and system development through to engine and vehicle manufacturers. In the multimedia story "refuels - rethinking fuels" below, we have recounted the content and results of the project. And the work continues in the follow-up project reFuels and the platform project InnoFuels.

Two in one: "reFuels" and "InnoFuels" projects 
Building on the reFuels results, the InnoFuels project was launched in February 2023: The platform project , which is funded by the German government, is working on the prerequisites for the rapid ramp-up of the production of renewable fuels. The aim is to network the many national and European research projects on the topic. The collaboration is intended to help accelerate the production of larger quantities of electricity-based liquid fuels and advanced biofuels. Click on the photo gallery below to find out more about the two projects.
The bioliq® project at KIT, which was completed at the end of last year, demonstrated early on how residual biomass such as straw can be converted into synthetic fuel - a technological milestone that is also highly relevant for current projects such as InnoFuels or Refinnieries for Future (Ref4FU). 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 ®.

Ein neuer Fachbericht des Plattformprojekts InnoFuels fasst zusammen, wie sich paraffinischer Diesel – insbesondere HVO – auf die Partikelmassen- und Partikelanzahl-Emissionen von Dieselmotoren auswirkt. Dabei werden sowohl die innermotorischen Emissionen als auch die Wirkung von Abgasnachbehandlungssystemen berücksichtigt. Das Papier liefert wichtige Erkenntnisse zu Motor- und Nachbehandlungsemissionen und kann somit Flottenbetreiber, Hersteller und Politik dabei unterstützen, den seit Mitte 2024 offiziell zugelassenen Kraftstoff als klimafreundliche Option sinnvoll und verantwortungsvoll einzusetzen.
Zum Paper
A workshop held in mid-February as part of the InnoFuels follow-up project focused on scenarios for the market ramp-up of e-fuels in road transportation. The 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.
