CO₂ capture, utilization and storage

We assess existing and planned processes in terms of their CO₂ emissions. In doing so, we examine possibilities for avoiding, reducing, utilizing, and storing emissions in the long term, and evaluate established, commercially available, and developing alternative technologies for long-term economic use by our customers. For CO₂ emissions that are technically or economically difficult or impossible to avoid, we develop potential extraction points, purification processes, transport and utilization routes. For the utilization of CO₂ (CCU), we develop processes for extraction from industrial, biogenic or atmospheric (DAC) gas streams.

Process-related emissions cannot always be avoided using alternative technologies. For such emissions that are difficult to avoid, we develop utilization concepts together with our customers. One example of this is CO₂-binding building materials, which bind CO₂ in mineral form through carbonation processes. To this end, we examine concrete and cement additives in our laboratory and develop them further together with our partners.

With proper management of a suitable geological storage site, CO₂ can be permanently isolated from the atmosphere. Thanks to our geotechnical expertise, we know the requirements for optimal operation and can help you determine a location and its storage potential. Our experts will accompany you from the initial feasibility study and borehole planning to CO₂ injection and monitoring.

Safety is particularly important to us. With our measurements of rock impermeability and our numerical solutions for CO₂ transport and storage, we support you in identifying and minimizing risks and develop concepts for monitoring the geological storage site and storage well - for greater safety and cost-effectiveness.

The mineralization of CO₂ is considered a particularly safe storage method, as the CO₂ is no longer in gaseous form but as a solid. To optimize the storage process, we provide data on mineralization rates and capacities of suitable storage rocks, which we have obtained through experimental laboratory work and geochemical modeling. We adapt our flexible test setups individually to project requirements and are thus able to realistically simulate a wide range of in-situ and ex-situ mineralization processes.
