The Green Twin project is at the cutting edge of digital applications for carbon capture and shows a potential to be scaled-up. Currently, Innomissions applications have included modelling work as a supporting activity; in Green Twins, models take the center stage and experiments are the support. You will also hear about how the CapSim project tackles algorithmic and thermodynamic challenges associated with CO2 capture simulation, and how It seeks to overcome challenges related to acidic gases, speciation, reactions, and thermodynamics.
