Kairos@C combines three first-of-its-kind innovations, embedded across the project. It is also the first time that a cross-border CCS chain is deployed for hard-to-abate CO₂ emissions, especially in Europe. On top of this, several elements in the chain have never been performed on such an industrial scale, e.g. Air Liquide CryocapTM technology, the energy efficient CO₂ liquefaction and export terminal (ten times the capacity of the largest CO₂ liquefaction unit in operation today) and the liquid CO₂ vessels.
