Following the Paris Agreement there is a global need for new technologies to reduce carbon emissions. Capture and storage of CO2 is a key technology in this respect. The International Energy Agency (IEA) estimates that the amount of CO2 captured will increase from about 40 Mt per year today to 5.6 Gt in 2050. The most suitable CO2 capture technology depends on process parameters such as the CO2 concentration, impurities, and other site-specific factors. Currently, for processes emitting high volumes of CO2 but at low CO2 concentration, no suitable CO2 capture technologies are commercially available. In addition, the cost of CO2 capture will need to be reduced from today?s level to be a competitive emission reducing alternative. To address these needs, researchers at the Norwegian University of Life Science (NMBU) have developed and patented Carbon Capture in Molten Salts (CCMS). CCMS captures CO2 in a molten salt mixture. The mixture is produced from abundant, non-toxic raw materials, with low levels of degradation thereby reducing costs. The CCMS process can also benefit in energy recovery. This capture process has fast reactions and a high absorption capacity. This makes it highly suitable for use in the metal producing industries, which is one of Norway's largest export industries. The technology has the potential to be commercially competitive compared to existing capture methods, particularly for flue gases with low CO2 concentration. The project will deliver results in three areas 1) Identification of the right market segment and industries, 2) Technoeconomic analysis and the pre-design for a prototype and 3) Preparation for further development and commercialization, including securing involvement of an industrial partner for the prototype and pilot construction. This project can trigger the establishment of a new company, further investments, and eventually commercial sales.
