Heidelberg Materials and Linde have established a joint venture under the name “Capture-to-Use” (CAP2U) to build and operate a state-of-the-art carbon dioxide capture and liquefaction plant. The carbon capture and utilisation (CCU) facility in the cement industry is scheduled to start operations in 2025 at Heidelberg Materials’ Lengfurt plant in Germany. The facility will enable the captured CO₂ from cement production to be reused as a valuable raw material in manufacturing applications. The planned volume of purified and liquefied CO₂ is around 70,000 tonnes per year.
The plant is being designed and built by Linde Engineering. Based on an amine scrubbing system specially developed for flue gases, the carbon dioxide will be separated directly from part of the exhaust gas stream from the cement clinker kiln. Equipment for purification and liquefaction, tanks for intermediate storage of the product, and loading facilities are also part of the project scope.
Linde brings its expertise in forward-looking, gas-based environmental technologies that allow customers around the world to increase their productivity while reducing their environmental footprint.
Heidelberg Materials has already successfully tested CO2 capture based on amine scrubbing technology on an extended laboratory scale at its Norwegian cement plant in Brevik.
