Decarbonisation Technology August 2025 Issue

The pioneering demonstration plant is also aligned with decarbonisation commitments across Denmark. For example, the Danish Climate Act aims to reduce GHG emissions by 70% by 2030 compared to 1990 levels and to achieve net zero by 2050 (State of Green, 2025) . According to the Danish Climate Council’s 2025 Status Report, the nation is on track to achieve its 2O25 target (50% emissions reduction), marking an exceptional achievement (Klimaraadet, 2025) . This progress has been recognised by the World Economic Forum, which lists Denmark as one of Europe’s top performers in its Energy Transition Index (ETI), which tracks progress and preparedness for an ‘equitable, secure and sustainable energy future’ (WEF, 2024) . DLR’s Leuna chemical complex in Germany Topsoe has also been selected to deliver key technologies for the German Aerospace Center’s (DLR) SAF production demonstration plant, located at the Leuna Chemical Complex in Germany. Topsoe’s eREACT and hydroprocessing technologies will form a key part of DLR’s e-fuels Technology Platform Power-to-Liquid Fuels (TPP) and will be integrated with Sasol’s Low-Temperature Fischer-Tropsch (LTFT) technology. This is a significant milestone for Topsoe, as this TPP is set to become the world’s largest research facility for e-fuels production and the first to enable end-to-end demonstration and testing of fuels synthesised using electrical energy across the entire technology chain. Designed with a modular structure, the plan allows for flexible integration and evaluation of different processes technologies, making it an ideal proving ground for scaling innovations to industrial levels. Once commissioned – planned for Q4 2027 – the demonstration plant will produce 2,500 tons per year of e-fuels, mainly SAF, using renewable feedstock like biogenic CO₂ and green hydrogen. This project highlights the scalability and commercial potential of eREACT in enabling the transition to low-emission aviation fuel on an industrial scale. Global impact Despite strong progress in Denmark, globally, the energy transition is facing a critical

challenge of balancing energy security, affordability, and sustainability. Combined with continued growth in energy demand, driven by demographics, economic, and technological developments, it is essential to accelerate the deployment of technologies that allow energy- intensive industries to diversify their use of fuels and chemicals solutions and reduce their carbon emissions. The world is currently undergoing an energy transition, not a switch. There is a need to develop, scale, and deploy all available solutions to decarbonise every sector across all continents. In light of this, technology versatility is key, which is why eREACT is transformative. Using a single piece of equipment to produce multiple fuels (e-SAF, e-methanol, and blue hydrogen) ensures numerous end-use cases from just one infrastructure investment. Since each fuel also has more than one application, further advantages can be realised. e-SAF For example, e-SAF can be used as a low-carbon alternative to conventional jet fuel in passenger and cargo aviation, reducing emissions by up to 80% (IATA, 2025) . All SAF, including e-SAF supports long-haul and Figure 2 eREACT FrontFuel demonstration plant in Foulom, Denmark
