Nowadays, both governments and scientists agree with the fact that carbon dioxide (CO₂) is an important greenhouse gas impacting global warming. Undoubtedly, in order to mitigate substantial climate change, CO₂ emissions from anthropogenic activities have to be reduced as much as possible.
This can only be achieved by a combination of measures, as efficient use of energy and the development and implementation of energy-saving technologies.

Besides this, carbon dioxide capture and storage (CCS) is considered to be a viable option to capture CO₂ emissions on a short to intermediate time scale from power plants. It could facilitate the transition from the fossil fuel era towards an era of sustainable energy usage.

CCS involves, capture of CO₂ from flue gas of power plants and its long-term storage in appropriate geological formations. Suitable storage locations are depleted oil and gas reservoirs and saline aquifers, i.e. deep porous strata filled with groundwater that is too saline for consumption or agricultural use.

Worldwide, numerous research projects are investigating the feasibility and potential risks of CCS. Large-scale CO₂ injection tests are presently conducted in Algeria, Australia, Canada and Norway.
