Geological storage of CO2 in the subsurface can give an important contribution in reducing the global climate changes. In order to do that, the Norwegian research community has to develop four entirely new techniques and methods. This short article gives an overview of what type of research NGI is involved on the CO2 front.
The percentage of the greenhouse gas CO2 in the atmosphere has increased radically during the last 100 years. This development is about to create global climate changes. Storing CO2 in the subsurface can give an important contribution to reduce the emission of CO2 into the atmosphere and therefore contribute to a solution of the climate problems. There is a technological race taking place to develop the needed technology and methods for the time being in the following areas:
- CO2 must be trapped and cleaned from exhaust gasses effectively and economically
- Suitable storage sites must be located/discovered and characterised
- Safe techniques must be developed for the injection of the CO2 into the target reservoir
- Methodsv must be developed to monitor the behavior of CO2 in the reservoir and subsurface
