Abstract

Methods and systems for enhancing rates of carbonation of peridotite both in situ and ex situ are disclosed. In some embodiments, the methods and systems include the following: fracturing a volume of peridotite; heating the volume of peridotite; injecting an adjustable flow of carbon dioxide into the volume of peridotite; injecting bicarbonate materials into the volume of peridotite; and forming carbonate with the volume of peridotite and the carbon dioxide in an exothermic reaction thereby generating a self-sustaining heat source, the heat source heating the volume of peridotite.
