In the case of in-situ mineralization processes there is no product per se , and in most prior ex-situ CCS suggest either return CO2 mineral to environment, e.g., deposited in the oceans. Neither of these approaches have any economic driver and rely on carbon credits for income . In some cases, where MgCO3 is formed it is proposed to use the product in the building industry. Any economically viable mineralization process should make a product with a greater value than the reagents used.
