(Hemmingstedt, April 7, 2021) The carbon dioxide (CO₂) footprint of the construction industry is currently still significant. Holcim is taking a leadership role in the climate-friendly transformation. The goal is “net zero company”, i.e. cabon neutrality by 2050 – with mandatory, clearly defined scientifically based targets. The best example of this is the cross-sector partnership WESTKÜSTE100 already formed in Schleswig-Holstein at the beginning of 2019. The goal is to produce green hydrogen from offshore wind energy and to use the waste heat generated in the process. The hydrogen will then be used for the production of climate-friendly fuels and fed into gas grids – some of it will also be used directly in the refinery process.
After receiving funding approval from the German Federal Ministry of Economics and Technology, the project started in August 2020 with a total funding amount of around 36.5 million euros. Since then, various larger and smaller sub-projects have been running in the real-world laboratory WESTKÜSTE100. In mid-April 2021, the sub-project OXYFUEL100 was successfully completed. At the Lägerdorf cement plant, two comprehensive studies
were carried out under the leadership of Holcim to prepare investments for the conversion to an oxyfuel process (technical partners thyssenkrupp Industrial Solutions and Linde). In addition to the oxyfuel process, the technical and economic feasibility of downstream CO₂ extraction, treatment and transmission was also examined. The results of the feasibility study from the real-world laboratory are extremely positive. They provide Holcim with necessary information for upcoming investments.
