Carbonation is a solidification/stabilization process. The availability of a carbon dioxide (CO2) fixation technology would serve as insurance in case global warming causes severe restrictions on CO2 emissions. In order to prevent rapid climate change, it will be necessary to stabilize CO2 as carbonate by the carbonation process. Carbonation of the widely occurring mineral olivine (Mg2SiO4) converts CO2 into an environmentally benign mineral magnesite (MgCO3).
