Mineral Carbonation

Mineral carbonation, whether occurring naturally or through engineered processes, represents a significant avenue for addressing the escalating challenge of carbon dioxide (CO2) emissions. The natural variant of this phenomenon unfolds over geological epochs as rocks weather and react with atmospheric CO2, forming stable carbonates. In the realm of contemporary environmental science and engineering, researchers are actively investigating artificial or accelerated mineral carbonation as a viable method for carbon capture and storage (CCS). This innovative approach involves capturing CO2 either from industrial emissions or directly from the atmosphere and then engaging it in a chemical dance with specific minerals. The ensuing reaction results in the formation of stable carbonate compounds, effectively transforming gaseous carbon into a secure, solid state. The appeal of mineral carbonation lies in its potential for long-term carbon storage within geological formations, contributing to the global effort to mitigate climate change. Despite its promise, the widespread adoption of mineral carbonation faces hurdles. The availability of suitable minerals, the substantial energy demands associated with the reaction, and the economic viability of large-scale implementation are challenges that necessitate thorough consideration and innovative solutions. Nevertheless, as the urgency to address climate change intensifies, mineral carbonation emerges as a hopeful contender in the arsenal of carbon capture and storage strategies.
