Subsurface CO2 storage – Critical Elements and Superior Strategy
Project name: SUbsurface CO2 storage – Critical Elements and Superior Strategy
Project coordinator: Christian Michelsen Institute (CMI)
Project partners: 8 Norwegian research institutes, 5 industrial partners, numerous international partners
Local (CGB) investigator(s): Laila J. Reigstad, Andrew K. Sweetman (Associate Professor II at CGB and NIVA researcher), PhD student Karin Landschulze and first-semester CGB masters student, Camilla Bøe
Project's main objectives:
To provide a sound scientific base for CO2 injection, storage and monitoring, to fill gaps in strategic knowledge, and provide a system for learning and development of new competency.
- To improve our understanding and ability to quantify reactions and flow in storages
- To develop advanced modelling tools for multiphase flow and reaction
- To investigate the integrity of sealing materials, and test their retention capacity
- To improve the understanding and develop new models for the relation between flow and geomechanical response
- To improve the understanding and develop new models for geochemical-geomechanical interaction
- To improve the understanding and modelling tools for flow and reaction in faults and fractures
- To test, calibrate and develop new monitoring techniques
- To improve the understanding of shallow marine processes and the ecological impact of CO2 exposure, and develop marine monitoring methods
- To reduce risk and uncertainties in sub-surface CO2 storage
- To facilitate extensive and high quality education for CO2 storage
CGB researchers are involved with Work Package 5 (WP5): the marine component
This activity will address issues regarding CO2 seeps through the seabed from below in terms of (i) knowledge gaps on processes in the upper sediment /benthic boundary layer; (ii) ecological impact from CO2 exposure; (iii) monitoring technologies. This will be achieved through innovative research, coupling lab-, mesocosm and in-situ studies with theory and simulation modelling, and thereby setting the framework of ad-hoc monitoring programs.
Four highly cross-disciplinary core tasks are identified.
- Effects of CO2 leakage on the subsurface biosphere
- Interaction and processes between shallow sediments and the water column
- Consequences of leakage on marine benthic ecosystems
- Monitoring (Marine)
