More efficient CO₂ capture from cement factories

More cost-effective CO₂ capture

For several years, the Research Council and Gassnova have collaborated with actors from other countries through the ACT platform. This has resulted in several good international projects. One of the projects is called AC²OCEM, where leading research environments from several countries have studied how oxyfuel technology can provide more cost-effective CO₂ capture from cement factories.

The project was led by the University of Stuttgart and has had partners from Norway, Germany, France, Helles and Switzerland. From the Norwegian side, SINTEF and NTNU have played key roles.

Oxyfuel technology means that combustion processes take place with pure oxygen instead of pure air. This will provide a simpler process for CO₂ capture.

Oxyfuel for cement factories

In the ACT²OCEM project, the use of oxyfuel for cement factories has been studied. Pilot-scale experiments have been carried out and this is combined with numerical modeling and simulation to describe how components in a cement factory can be designed to optimize CO₂ capture.

The results from the project show that oxyfuel can be an alternative in the future for cement factories. Techno-economic analyzes and life cycle analyzes from AC²OCEM will be important tools for the design of CO₂ capture facilities for cement factories.

More details about the project are available from the project’s website and the Research Council’s project bank.
