CO2Crete – alternative storage of CO2, a complement to geol. storage

The cement industry, and other businesses, plan to capture and store their CO₂ emissions to reach their climate goals. Geological storage of CO₂ in Sweden is not possible within the next few years and the captured CO₂ therefore needs to be transported long distances for storage in other countries. Although, other options for permanent storage of CO₂ exists: carbonation. The CO2Crete project aims to develop a technical infrastructure and methodology for evaluating the potential for CO₂ storage in mineral residues from the mining, metal, and construction industry as well as for alkali-rich materials.

The goal of the project is to develop a list of potential carbon sinks on land and also investigate whether the storage (carbonation) in mineral materials can create new products (SCMs) that partially can replace cement in concrete. The CO2Crete project will also investigate possibilities for upscaling through evaluation and validation of different methods for carbonation, based on facts. In this way, the results of the CO2Crete project will help companies to be able to make the right decisions for investments and to contribute to a more circular economy.

The project is carried out with support from the Swedish Agency for Economic and Regional Growth and the EU from the Just Transition Fund. The support relates to the National Programme for the Just Transition Fund 2021–2027. The Just Transition Fund is an EU fund that focuses on the industries and counties with very high carbon emissions. The fund aims to reduce emissions and tackle the challenges associated with the transition.
