This project project combines fundamental and applied research, and experiments and modelling in a unique way: from fundamental material-activity relations and insights into the reaction pathways during DAC with potassium-carbonate-based sorbents, over kinetic models, to heat and mass transport assessment and material shaping at the application scale. By understanding all these factors we aim to develop, together with our industrial partner Shell, new robust sorbent materials which can capture CO2 from air.
