Carbon capture and storage (CCS) is considered to be one of the options to mitigate climate change by reducing the amount of carbon dioxide (CO2) emissions released to the atmosphere. After injection of CO2 into an appropriate storage formation, the fraction retained depends on a combination of physical and geochemical trapping mechanisms. Following the Intergovernmental Panel on Climate Change (IPCC 2005) this session provides a forum for the discussion of the questions:
- What are the physical and chemical processes happening to CO2 in the subsurface?
- What information do we have on these processes?
- Can we monitor CO2 once it is injected and if, how reliable is it?
- What monitoring techniques are available for leaking CO2?
- Is it possible to predict the long-term storage of CO2 in geological reservoirs?

Further, contributions presenting results from national and international R&D projects, fundamental and conceptual studies, and pilot and large scale projects according to CO2 storage in geological systems are invited.
