Method and systems for subsurface carbon capture

A method includes choosing a well site for Carbon Capture and Sequestration, preparing the well site for Carbon Capture and Sequestration, and hydraulic fracturing a target area in a formation using fracturing fluid containing a reactant proppant to form fractures in the target formation and to trap the reactant proppant in the fractures. The target formation is in communication with a well in the well site. Such methods also include injecting a volume of carbon dioxide into the fractures in the target formation, chemically reacting the volume of carbon dioxide with the reactant proppant, converting the volume of carbon dioxide into a carbonate, and storing the carbonate in the fractures in the target formation.
