KODECO NET ZERO project

The KOdeCO net zero project aims to make Holcim’s Koromačno plant the first to produce net-zero cement in Croatia and the Mediterranean. It will establish a first-of-its-kind, end-to-end carbon capture and storage value chain between the plant and storage under the Mediterranean. 

Adopting a highly scalable technology, the project uses renewable electricity, which enables 20% electricity savings, higher efficiency, circularity of condensate and reduced water consumption. 

With a vision for the Koromačno plant to be net-zero by 2030, the project aims to capture and store around 366,000 tons of CO₂ per year. The project’s decarbonization efforts led to it being selected for an EU Innovation Fund grant in 2023 as well as the Just Transition Fund.

The project will capture CO₂ through absorption end-of-pipe technology. It will use Air Liquide’s Cryocap™ FG non-intrusive carbon capture and liquefaction technology, which is adapted to the direct capture of clinker production flue gas. 

The Koromačno plant will provide intermediate storage to prepare liquefied CO₂ to be loaded onto vessels and then permanently stored under the Mediterranean. 

The project will also integrate first-of-their-kind water treatment and desalination plants to further decrease Koromačno’s environmental footprint with the aim of becoming a zero fresh water usage site.
