System and method for permanent carbon dioxide sequestration in peridotite rocks

Abstract

The present invention provides a system and method to mineralize CO2 into peridotite rocks in a controlled and efficient manner removing carbon permanently from the atmosphere. Carbon dioxide sequestration into peridotite rocks happens naturally by means of natural weathering. However, this process is so slow and might take thousands of years to transform considerable amount of CO2 into carbonate rocks. The present invention, however, shortens the time of mineralization considerably in a controlled and quantifiable manner. This is typically done by injecting CO2 into peridotite rock formation and creating an efficient reaction pathways and conditions for the mineralization reaction to happen and therefore store CO2 by conversion into magnesite (MgCO3) and calcite (CaCO3).
