Abstract: A method of making a hydraulic fracturing slurry can include contacting an aqueous solution comprising calcium ions with a carbon dioxide source producing a carbonated aqueous solution. Substrate particles can be submerged in the carbonated aqueous solution to produce a calcium carbonate coated proppant wherein the carbon dioxide is sequestered in the calcium carbonate. The calcium coated proppant can be combined with hydraulic fracturing fluid to produce a hydraulic fracturing slurry. Alternatively, the calcium carbonate coated proppant can be combined with silica sand to produce a proppant composition used in a hydraulic fracturing slurry.
