A consortium of 15 companies including Neste have successfully concluded a joint ‘E-Fuel research project’ in which high temperature electrolysis (SOEC), carbon capture, and hydrocarbon synthesis technologies were demonstrated and production of synthetic e-fuels was also accelerated.

Espoo/Finland – Renewable hydrogen produced by green electricity and carbon capture and utilization (CCU) play an important role in combating climate change. Low-emission e-fuels produced using these technologies are particularly suitable for segments that are difficult to electrify, such as aviation and marine. The joint E-Fuel research project demonstrating high temperature electrolysis (SOEC), carbon capture, and hydrocarbon synthesis technologies has now come to its successful end. During the three-year project, the development of synthetic e-fuels towards commercial scale production was accelerated.

The E-fuel research project that has been funded by Business Finland and consortium partners and coordinated by VTT is part of the Neste Veturi ecosystem. The project consortium of 15 partners covered all parties in the value chain from CO2 capture to green hydrogen and fuel production, logistics, as well as users of the transportation fuels in aviation and road and marine transport.

The project successfully generated hundreds of kilograms of synthetic hydrocarbons intended for the production of novel sustainable transportation fuel. The hydrocarbons were refined by Neste mainly into carbon neutral synthetic e-diesel, which was tested on a diesel-powered tractor in late 2023. During the project, technologies of the consortium companies were developed further, and the produced diesel burned more cleanly than fossil and renewable diesels in the current market. E-fuels can be considered carbon-neutral, as they are produced using captured CO2 emissions and renewable hydrogen, effectively offsetting the carbon dioxide released during combustion in an engine.

“The research and development of Power-to-X technologies is one of our key focus areas. E-fuels offer a way to expand the carbon-neutral transport fuel pool beyond biomass-based renewable fuels to replace fossil fuels. In the aviation sector, specifically, where the constraints of battery range and weight pose challenges, the development of sustainable electric aviation fuels suitable for current aircraft and distribution infrastructure plays an important role in reducing the use of fossil fuels. It has been our pleasure to participate in the E-Fuel project, the results of which create a good foundation for continuing the development work,” says Dietmar Huber, Vice President of Innovation Business Platform Power-to-X at Neste.

“I’m happy about the very successful results of the project. VTT together with industrial partners developed further technologies for green hydrogen production, CO2 capture and e-fuels synthesis and finally we successfully demonstrated the integration of these process parts and the production of e-fuels. Furthermore, we were able to demonstrate the high quality of the produced paraffinic e-fuel with low emissions in the field test. We also gathered and developed valuable information on the profitability and sustainability of e-fuels production,” says VTT Research Professor Juha Lehtonen, responsible leader of the project.
