- The CCU facility will capture and liquefy 70,000 tonnes of CO₂ annually.
- Operations are scheduled to start in 2025 at the Lengfurt plant in Germany.
- The project receives €15 million from the German Federal Ministry for Economic Affairs and Climate Action.
- Linde will market the majority of the captured CO₂, with some used for new recycling technologies.
Project Overview
Heidelberg Materials and Linde have formed a joint venture named "Capture-to-Use" (CAP2U) to build and operate a carbon dioxide capture and liquefaction plant. This facility, the first of its kind in the cement industry, will be located at Heidelberg Materials' Lengfurt plant in Germany and is set to begin operations in 2025. The plant will capture and purify around 70,000 tonnes of CO₂ annually from cement production for reuse in various manufacturing applications.
CO₂ Utilization
The majority of the captured CO₂ will be marketed by Linde, with applications in the food and chemical industries, such as carbonated mineral water. A smaller portion will be used by Heidelberg Materials to advance new CO₂ recycling and recarbonation technologies.
Funding and Support
The project is supported by €15 million in funding from the Decarbonisation of Industry program, under the German Federal Ministry for Economic Affairs and Climate Action (BMWK). This funding underscores the importance the German government places on innovative carbon capture and utilization solutions.
Technological Implementation
Linde Engineering, a leader in CO₂ facilities, will design and build the plant. The facility will use an amine scrubbing system to separate CO₂ directly from the exhaust gas stream of the cement clinker kiln. The project will also include equipment for purification and liquefaction, as well as storage tanks and loading facilities.
Previous Experience
Heidelberg Materials has previously tested CO₂ capture using amine scrubbing technology at its Norwegian cement plant in Brevik from 2012 to 2016. Linde brings expertise in gas-based environmental technologies, enhancing productivity while reducing environmental impact.
