OLYMPUS carbon capture project
OLYMPUS is a flagship project in Holcim’s European decarbonization roadmap. It will lead to the development of storage capacity in southern Europe. It uses a highly innovative technology combination that merges OxyCalciner & Cryocap™ Oxy.
With a target operational date of 2028, the project aims to capture and store 1 million tons of CO₂ annually. In 2023, the project was selected for a grant from the EU Innovation Fund.

The technology behind the project
The combination of OxyCalciner & Cryocap™ Oxy is a novel technology that will enable low capture variable cost. Through this project, Holcim will transform the Milaki cement plant into a net carbon removal site.
It uses OxyCalciner technology to capture CO₂ from the flue gas of the Milaki cement plant. The captured CO₂ will then be transported to the Cryocap plant to be liquefied and stored.
The Cryocap™ Oxy technology by Air Liquide captures and purifies CO₂ from flue gas through oxycombustion processes. It has a CO₂ capture rate of 98%. This technology can manage impurities, particularly high levels of nitrogen oxides, to ensure the quality and safety of the captured CO₂.
With our innovative OLYMPUS project, we are contributing to the decarbonization of our industry, leading the way towards a net-zero future in Greece and Europe.
