The carbon dioxide (CO2) footprint of the construction industry is currently still significant. Holcim is playing a leading role in the climate-friendly transformation. The goal is ‘net zero companies’, that is, climate neutrality, which is to become a reality by 2050 - with mandatory, clearly defined scientifically founded goals. The best example of this is the cross-sector partnership WESTKÜSTE100 that was formed in Schleswig-Holstein at the beginning of 2019. The aim is to produce green hydrogen from offshore wind energy and to use the waste heat generated in the process. The hydrogen is then to be used for the production of climate-friendly fuels and fed into gas networks - some of it will also be used directly in the refinery process.
Once the Federal Ministry of Economics had approved the project, it commenced in August 2020. The total amount of funding is around €36.5 million. Since then, various large and small sub-projects have been running in the WESTKÜSTE100 real-life laboratory. The sub-project OXYFUEL100 was successfully completed in mid-April 2021. At the Lägerdorf cement plant, two comprehensive studies were carried out under the direction of Holcim to prepare investments for the conversion to an oxyfuel process (technology partners thyssenkrupp Industrial Solutions and Linde). In addition to the oxyfuel process, the technical and economic feasibility of the downstream CO2 extraction, processing and forwarding was examined. The results of the feasibility study from the real laboratory are extremely positive.
