Characterization of Qatar’s surface carbonates for CO2 capture and thermochemical energy storage

Energy Storage in Earth-Abundant Dolomite Minerals

“…However, the CSP plants do have the potential to operate at higher temperature (>600 • C) if an alternative to molten salt is found [7]. A recent publication by Konstantinos Kakosimos et al [8] studied the characterization of surface carbonates obtained from various regions of the Qatar peninsula and have shown promising potential for applications in CO 2 capture and thermochemical energy storage. According to this report, dolomites have higher performance in terms of CO 2 sorption and storage capacity when compared to calcite, CaCO 3 [9][10][11].…”

“…An intergovernmental panel on climate change (IPCC) report [25] on reduction of greenhouse gases (GHG) emissions indicated they could be lowered by adhering to two stringent processes: (i) by sequestering and capturing atmospheric CO 2 or in coal power plants as produced CO 2 and (ii) developing thermochemical energy storage systems using earth-abundant materials. Based on such high-level recommendations, our project addresses the fundamental and applied aspects of calcium-magnesium carbonates [CaMg(CO 3 ) 2 ] or dolomites which have previously been shown to have potential in thermal energy storage applications [8,12,[18][19][20][21][22]. The present study is the first examination of the thermochemical energy storage feasibility in high-dolomite phosphatic pebbles obtained from the Florida Industrial and Phosphate Research (FIPR) Institute that are quite abundant in Central Florida's phosphate mining sites.…”
