CO2 transport, injection and storage – WP2

WP2 focuses on CO2 storage and on the transport-storage interface. As can be seen from the below table, the work will utilize a wide variety of first-class research infrastructure. As illustrated below, the WP is characterized by a strong collaboration with the ultimate goal to de-risk CO2 storage. To this end, WP2 will

  • Develop an accurate property model for CO2-brine in the presence of impurities.
  • Mature and validate tools for the safe, efficient and cost-effective design and operation of CO2 pipelines and injection wells.
  • Perform petrophysical chemical analyses for the characterization and selection of storage sites in Switzerland.
  • Design and perform decameter-scale experiments at the Mt Terri research rock laboratory to un-derstand the role of CO2 injection in modifying fault/fracture permeability through seismic and/or aseismic reactivation.
  • Reduce uncertainties in injection, storage and monitoring of CO2 produced by NG reforming for H2 production
