Assessment of Mineral Potential for Carbonation of CO2 in Saudi Arabia
A. Sahin1, A. Shaikh1, and M. Bashammakh1
Burning of large quantities of fossil fuels since the beginning of industrial revolution has increased concentration of CO2 in the atmosphere. This has resulted in significant adverse effects on the global climate as widely reported in the literature. Global warming, melting of polar ice-sheets and irregular weather patterns are all attributed to the CO2 concentration in the atmosphere. To save our planet from possible environmental disaster, a significant amount of reduction in CO2.emissions has been proposed through the capture and storage of CO2. Commonly considered techniques such as the storage of CO2 in depleted reservoirs and injecting it into producing reservoirs to enhance oil recovery have significant limitations in terms of their safety, cost and monitoring. Moreover, the amount of CO2 to be injected in such cases is rather limited, compared to that emitted to the atmosphere (28.5 Gt of CO2 in 2010). Therefore, the use of other techniques such as carbonation has been proposed.
