Linde and Heidelberg Materials hosted a groundbreaking ceremony for their large-scale carbon capture and liquefaction plant in Lengfurt, Germany.
Christian Knell, General Manager of Heidelberg Materials Germany, and Andreas X. Müller, Managing Director of Linde Gas Germany, welcomed around 50 guests to this milestone event on the construction site at the Lengfurt cement plant.
Under the name “Capture-to-Use” (CAP2U), Heidelberg Materials and Linde have established a joint venture to build and operate a carbon capture and liquefaction plant, which is expected to go into operation in 2025. The plant will enable the captured CO₂ from cement production to be utilised as a valuable raw material for industrial applications. Due to its purity, the processed gas will be suitable for use in both the food and chemical industries. 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 CO₂ 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.
For the implementation of the project at the cement plant in Lengfurt, contributions of the joint venture will be supplemented by funding of around €15 million from the ‘Decarbonisation of Industry’ funding programme on behalf of the German Federal Ministry for Economic Affairs and Climate Action (BMWK).
