**HOLBORN Employs Topsoe Technology for German Renewable Fuels Complex**
In a groundbreaking move to reduce emissions and boost the production of sustainable fuels, HOLBORN Europa Raffinerie GmbH has selected Topsoe AS to supply cutting-edge technology for its proposed renewable fuels complex in Hamburg, Germany. The new facility, set to commence operations in early 2027, will be integrated within HOLBORN’s existing 5-million tonne/year refinery, bringing the company closer to its ambitious energy transition goals.
As part of the mid-August contract, Topsoe will license its proprietary Hydroflex technology. This innovative solution will enable the processing of waste and residue feedstocks into sustainable aviation fuel (SAF) and renewable diesel, meeting all global specifications for these fuels. The Hydroflex technology is particularly vital for HOLBORN, as it allows the conversion of various organic fats, oils, and greases into drop-in renewable jet fuel and diesel, thereby addressing the specific feedstock requirements of the project.
HOLBORN’s selection of Hydroflex aligns with its broader strategy to reduce emissions and enhance the supply of sustainable fuels like renewable diesel and SAF. This initiative is also in line with the European Union’s Renewable Energy Directive (RED III), which aims to increase the use of renewable energy sources in the region.
The planned hydrotreated vegetable oil (HVO) complex, designed to produce 220,000 tonnes per year of high-quality HVO—or green diesel—and SAF, will utilize biomass-based waste and residue feedstocks sourced from the agribusiness sector. This project represents a significant step in HOLBORN’s long-term transformation process, which focuses on replacing crude oil with alternative raw materials and embracing renewable and circular solutions.
Additionally, HOLBORN has partnered with Maire SPA’s Rome-based subsidiaries—KT-Kinetics Technology SPA and NextChem SPA—for engineering, procurement, and construction services. This collaboration includes the development of a pretreatment unit for
