- The CCU facility will capture and liquefy 70,000 tonnes of CO₂ annually.
- Operations are set to begin in 2025 at the Lengfurt plant.
- The project receives €15 million from the BMWK funding program.
- Captured CO₂ will be used in food and chemical industries.
Project Overview
Heidelberg Materials and Linde have formed a joint venture named "Capture-to-Use" (CAP2U) to establish 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 expected to commence operations in 2025. The plant aims to capture and reuse approximately 70,000 tonnes of CO₂ annually from cement production.
CO₂ Utilization
The majority of the captured CO₂ will be marketed by Linde, with applications in the food and chemical industries due to its high purity. A smaller portion will be utilized by Heidelberg Materials to advance CO₂ recycling and recarbonation technologies. This initiative is part of a broader strategy to reduce carbon footprints and explore sustainable uses for CO₂.
Funding and Support
The project is supported by a €15 million grant from the Decarbonisation of Industry funding program, under the German Federal Ministry for Economic Affairs and Climate Action (BMWK). This funding underscores the importance of the project in the context of Germany's climate goals.
Technical Implementation
Linde Engineering is responsible for designing and building the facility, leveraging its expertise in CO₂ technologies. The plant will use an amine scrubbing system to separate CO₂ from the exhaust gas stream of the cement clinker kiln. The project includes equipment for purification, liquefaction, and storage, as well as loading facilities for the processed CO₂.
Background and Expertise
Heidelberg Materials has previously tested CO₂ capture technology at its Brevik plant in Norway. Linde contributes its experience in gas-based environmental technologies, aiming to enhance productivity while minimizing environmental impact.
