Geochemical Carbon Sequestration

Geochemical Carbon Sequestration is an innovative process aimed at mitigating the effects of climate change by capturing and storing atmospheric carbon dioxide (CO₂) in geological formations. This method leverages natural chemical reactions between CO₂ and minerals, such as silicates and carbonates, to form stable, solid carbonates. By converting gaseous CO₂ into solid minerals, this approach ensures long-term storage and minimizes the risk of carbon release back into the atmosphere.

Key techniques in geochemical carbon sequestration include mineral carbonation and enhanced weathering. Mineral carbonation involves the direct reaction of CO₂ with naturally occurring minerals, often in subsurface reservoirs, to form stable carbonates like calcite and magnesite. Enhanced weathering, on the other hand, accelerates natural rock weathering processes where CO₂ reacts with minerals on the Earth's surface, also resulting in stable carbonates.

Geochemical Carbon Sequestration offers a promising pathway to reduce greenhouse gas concentrations effectively. As an integral part of comprehensive climate mitigation strategies, it complements other approaches such as biological and technological carbon capture systems, playing a critical role in achieving global climate targets and fostering a more sustainable future.
