How can CO2 from industrial flue gases be transformed from a waste product into a valuable raw material? That is the central ambition of IKKA-TECH, which will demonstrate a new technology that permanently captures CO2 by converting it into high-purity calcium carbonate – a material widely used in products such as paints, plastics, paper and construction materials.
The technology is based on natural geological processes inspired by the unique mineral formations found in Ikka Fjord, Greenland, where CO2 is naturally bound over time into stable minerals. IKKA-TECH translates this natural process into an industrial solution that both reduces CO2 emissions and creates a valuable new product.
The project will establish a pilot plant on the island of Fur, directly connected to an industrial flue gas source. Here, the technology will be demonstrated under realistic operating conditions, providing evidence that CO2 can be captured and mineralised efficiently at industrial scale. The objective is to pave the way for a commercial solution that enables companies not only to reduce their carbon footprint but also to create value from the CO2 they emit.
For the Climate Foundation, IKKA-TECH exemplifies the type of project that can accelerate the green transition through collaboration between research, technology development and industry. The project helps move a promising technology from development to demonstration while strengthening the emergence of new green value chains and business opportunities.
IKKA-TECH is carried out through a broad partnership of companies and research institutions with support from Innovation Fund Denmark.
