Life Cycle Assessment of a CCU process: CO2 Capture and Mineralisation by Serpentine

Global Warming and the problems it bring are becoming increasingly concerning and possess huge challenges for the future if we do not take the necessary actions. Reaching the climate targets of the Paris Agreement necessitates the implementation of Carbon Dioxide Removal methods. Storage option after capturing has its own challenges about financial sustainability as it is not a commercial product by its own and require funding to ensure its occurrence as it is not being sold. However, Carbon Capture and Utilization (CCU) has a potential in terms of generating revenue by its own. CCU methods except mineralization of CO2 lack the permanent storability, namely, non-reversibility function, which is required for being a Carbon Dioxide Removal method. Therefore, Mineralization of CO2 by Serpentine, or in another words, Carbonation of Serpentine, is a CO2 utilization option where the CO2 can be trapped in the mineral permanently inside the product MgCO3. While all the captured CO2 is used in the production of MgCO3, Silica is also generated and utilized as the secondary product.
