Hot potassium carbonate

Hot potassium carbonate, HPC, is a method used to remove carbon dioxide from gas mixtures, also referred to as carbon scrubbing. The inorganic compound potassium carbonate is mixed with a gas mixture and the liquid absorbs carbon dioxide through chemical processes. The technology is a post-combustion capture process and is a form of chemical absorption.
HPC can be used for carbon capture and storage as well as carbon capture and utilization. The technology is planned to be used on full scale on a heat plant in Stockholm from 2025.
