CCS - CO2 capture utilization and storage

CCS (Carbon Capture and Storage) is a growing field of research with the purpose of significantly reducing CO2 emission and potentially create negative emission. The technology development is intended for small, medium, and large industry. CO2 is extracted from exhaust gas (e.g. combustion), industrial gas (biogas, natural gas, syngas etc.) or an air type system (direct air capture, fermentation). It is transported in pipes and potentially used in products (e.g. biofuels) or stored underground e.g. in old gas reservoir, aquifers etc.

CO2 Capture

Our capture initiative has several focus areas: 1. lab measurements of chemical properties like CO2 solubility, density, viscosity, surface tension, heat of absorption, reaction rate kinetics using a wetted wall, and solid precipitation from liquid solvents. The activity of supported by 2. thermodynamic modelling using the extended UNIQUAC model and CPA. The software is available to the CERE consortium and to researchers. The same modules are also available as Aspen Plus user models. 3. DTU CERE is continuously developing a rate based model called the CAPCO2 model which is available through Excel and Aspen Plus. 4. Process simulation in Aspen Plus and standalone software with the aim of process optimization, energy reduction, and efficiency increase 5. The work is validated by our 10m packed absorber pilot. 6. New innovative applications like enzymes, gas hydrates, ionic liquids etc.

CO2 transport

CO2 is transported by ship, truck, or in pipelines. This entails a possible corrosion risk. We focus on the experimental electrochemistry, e.g. cyclic voltammetry, linear polarization resistance and weight loss measurements at both low and high pressure. Flexile risers are polymer pipes which are used in reservoir management to transport gas. The pipe is permeable to CO2. The measurement of high pressure diffusion and corrosion of CO2 in the riser casing is one of our activities. The complex mixture of CO2, H2O, and gas impurities are simulated using equations of state such as CPA and SAFT for polymer systems.

CO2 utilization

By using CO2 in products, it is not emitted into the atmosphere, whereby emissions are reduced. Our activities focus on the extraction of valuable products, polymerization, and the complex chemistry of molecular interaction. This is modelled using the CPA equation of state.

CO2 storage

CO2 can be permanently removed from the atmosphere by storing it underground. Our activities focus on: 1. High pressure fluid properties between CO2, brine, and rock. This includes 1. Equilibrium data (vapour and solid) and physical-chemical properties and dissolution of carbonates. 2. Enhanced Oil Recovery (EOR) by core flooding and CT scanning chemicals. 3. Rock mechanics. 4 Storage of CO2 as hydrates by swapping CO2 with methane in naturally occurring hydrates.
