CO2 Capture and Storage
Energetic Transition. Challenges and Outlooks

The measures described above can be supplemented by solutions aimed at capturing and storing a portion of the emitted CO₂. One option is to increase biomass production in previously fallow areas (carbon sinks). However, it is not always easy to determine and monitor the carbon footprint over time.

CO₂ capture and storage is applicable in cases of concentrated CO₂ emissions, such as those from a large-scale coal-fired power plant.

Figure4 shows a diagram of a CO₂ capture and storage process, which involves extracting CO₂ from flue gas—typically through solvent scrubbing—compressing the extracted CO₂, and transporting it to an underground storage site. The CO₂ can then be injected into the subsurface and stored permanently.
