Mineral Carbonation

Mineral carbonation is an innovative approach in the realm of carbon capture and storage (CCS) technologies, offering a promising avenue for mitigating the impact of anthropogenic carbon dioxide (CO2) emissions on climate change. This process leverages the Earth's natural carbon cycle, where over geological timescales; CO2 reacts with certain metal oxides or silicate minerals to form solid carbonates. In contemporary applications, researchers are actively exploring mineral carbonation as a means to permanently sequester CO2 emissions from industrial processes and power plants. The fundamental reaction involves the combination of CO2 with minerals such as serpentine, olivine, or basalt. This union leads to the creation of stable carbonates, essentially transforming gaseous CO2 into a solid state. This conversion not only removes CO2 from the atmosphere but also contributes to the long-term storage of this greenhouse gas. The choice of minerals is crucial, and on-going research is focused on identifying optimal candidates that facilitate efficient and economically viable mineral carbonation. The potential of mineral carbonation lies in its capacity to provide a scalable and sustainable solution for carbon capture and storage. As efforts intensify to address climate change, enhancing the efficiency of this process is a primary objective. Researchers are exploring methods to accelerate the mineral carbonation reaction, optimize mineral sources, and streamline the overall sequestration process. Successful developments in these areas could position mineral carbonation as a robust tool in the global fight against rising CO2 levels and climate change, contributing significantly to a more sustainable and environmentally conscious future.
