Artificial CO2 sequestering

Artificial CO₂ sequestering is the set of techniques used to capture and sequester CO₂.

Principle behind artificial CO₂ sequestering.

These techniques consist in extracting the CO₂ contained in fuels using various processes, concentrating this carbon dioxide (pure compressed gas, liquefied gas, carbonic snow or carbonates...) then storing it in order to isolate it from the atmosphere.

Different techniques for storing CO₂

Currently, there are three CO2 storing methods:

• geological storage;
• oceanic storage (Dense plume, Droplet plume techniques…) ;
• inert mineral storage.

Attempts to stimulate natural carbon sinks by geo-engineering are also being tested (ocean fertilisation).
