Long-term storage of CO₂
Since 2011, a project for the capture and storage of CO₂ (CCS – Carbon Capture and Storage) in the cement industry has been running at the Heidelberg Materials subsidiary Norcem in Brevik, Norway. The Norwegian government is expected to make a decision in October 2020 regarding financial support for implementing this project, which will involve the capture of 400,000 tonnes of CO₂ a year. According to the planned schedule, the CO₂ emissions captured as part of the project will be transported to an underground storage site below the North Sea from 2024.
At the Heidelberg Materials plant in Edmonton/Alberta, Canada, the organization Emissions Reduction Alberta (ERA) is providing 1.4 million Canadian dollars for a feasibility study for an industrial-scale project for the capture and storage of CO₂ (CCS – Carbon Capture and Storage). The study comprises technical designs, cost estimates, and a comprehensive profitability analysis. In the next step, detailed FEED studies will be carried out.
CCS Slite, Sweden
In our Slite plant on the Swedish island of Gotland, the world’s first climate-neutral cement plant is to be developed until 2030. The installation at the Slite plant will be scaled to capture up to 1.8 million tonnes of CO₂ annually, which corresponds to the plant’s total emissions. Additionally, the use of bio-based fuels in the cement production at Slite will be increased. A feasibility study is currently addressing questions of technology selection, environmental impact, legal aspects, financing, logistics and energy supply. According to the plans, the captured CO₂ is to be transported to a permanent storage site under the North Sea.
