The Assesment for CO₂ Sequestration Potential by Magnesium silicate Minerals in Turkey: Cases of Orhaneli-Bursa and Divrigi-Sivas Regions

Abstract

This paper examines the CO 2 sequestration potential of magnesium silicate minerals in Turkey for two example cases, the Orhaneli-Bursa and Divrigi-Sivas regions. The distribution and properties of the silicate mineral deposits are provided and the quantities of CO 2 that can be sequestered in these deposits is estimated. The silicate minerals in the Orhaneli and Divrigi deposits provide significant CO 2 sequestration capacity. Assuming 100% mineral carbonation efficiency, approximately 2.4 million tons/year of olivine and 6.5 million tons/year of serpentine would be required to sequester the CO 2 released by the power plants investigated in this study. Although more detailed studies are needed, it is concluded that this approach has potential given Turkey's large dunite (olivine) and serpentine reserves. Furthermore, the proximity of these deposits and active open-pit mines to thermal power plants emitting CO 2 facilitate the utilization of mineral carbonation.
