(Hem­ming­st­edt, June 25, 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.
