Project's main objectives:

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.

Sub-objectives are:

  • 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)
