# Carbon Mineralization. #### Carbon Mineralization Overview:. Carbon management can be achieved by permanently storing captured carbon in natural systems or other resources via carbon mineralization processes. Natural resources for carbon mineralization which are highly reactive with CO2 include natural brines and mafic/ultramafic rocks and minerals. The Carbon Mineralization Program is dedicated to developing resource assessments for carbon management focusing on:. Projects in the Carbon Mineralization Program support the resource assessments by:. | Carbon Mineralization Project Landing Pages | |. | Resource Assessment of Industrial Wastes for CO2 Mineralization | **University of North Dakota** |. | Subsurface Carbon Mineralization Resources in Hawaiian Basalt | **University of Hawaii** |. | Resource Assessment of Geological Formations and Mine Waste for Carbon Dioxide Mineralization in the US Mid-Atlantic | **Virginia Polytechnic Institute and State University** |. | Subsurface Mafic and Ultramafic Rock Mapping and Analysis for Carbon Mineralization in the United States (Submap-CO2) | **University of Texas at Austin** |.

## Heliyon. # Review article A review of carbon mineralization mechanism during geological CO2 storage. https://doi.org/10.1016/j.heliyon.2023.e23135Get rights and content. The CO2 trap mechanisms during carbon capture and storage (CCS) are classified into structural, residual, solution, and mineral traps. The latter is considered as the most permanent and stable storage mechanism as the injected CO2 is stored in solid form by the carbon mineralization. In this study, the carbon mineralization process in geological CO2 storage in basalt, sandstone, carbonate, and shale are reviewed. In addition, relevant studies related to the carbon mineralization mechanisms, and suggestions for future research directions are proposed. The carbon mineralization is defined as the conversion of CO2 into stable carbon minerals by reacting with divalent cations such as Ca2+, Mg2+, or Fe2+. Rock properties such as permeability, porosity, and rock strength can be altered by the carbon mineralization. Since changes of the properties are directly related to injectivity, storage capacity, and stability during the geological CO2 storage, the carbon mineralization mechanism should be considered for an optimal CCS design.

For example, CO2 can be stored in concrete, known as ex-situ mineralization, in a matter of hours or injected underground for geologic carbon storage, known as in-situ mineralization, where the process occurs within a few years. Different approaches for scaling carbon mineralization include enhanced oil recovery, carbon utilization, and rock weathering, each with its own method, process, and growth opportunity. **Ex-situ:** Carbon-mineralized alternatives to traditional building materials can avoid damaging practices such as quarrying and can use hazardous waste materials from other industrial processes as inputs (e.g., fly ash or steel slag), reducing the potential for harm to local communities and the environment. For example, while in-situ mineralization methods can store carbon durably in underground rock formations, there are concerns about potential leakage at injection sites and from CO2 transportation pipelines. In the design sector, landscape architects can lower a project’s carbon footprint by specifying ‘rock dust,’ a low-cost, surficial form of carbon mineralization that can replace synthetic fertilizers, enhance soil health, and store CO2.

While there are already ways to store carbon this way— enhanced oil recovery (EOR), for example, involves injecting liquid carbonate deep into sedimentary rock formations—mineralization technologies put CO2 through a chemical reaction by which it becomes a mineral within igneous or metamorphic rock. Some naturally occurring minerals, like olivine or basalt, absorb carbon upon exposure. Underground mineralization transforms liquid carbonate into rocks like basalt, olivine, and other types of ultramific rocks by injecting it deep underground, where it reacts with the existing rock to change form. Above ground mineralization, also known as Enhanced mineralization, is a carbon removal technology by which weathering, or the exposure of carbon dioxide to crushed basalt or olivine, is sped up via industrial processes in order to sequester carbon. Scientists are currently developing methods of enhanced mineralization for carbon sequestration using ground-up basalt and olivine that can be added to soil or even the ocean, where it would absorb carbon dioxide.

Engineered carbon mineralization emulates and accelerates natural rock weathering, whereby calcium (Ca) and magnesium (Mg) silicate minerals react with carbon dioxide dissolved in water to form calcium and magnesium carbonate minerals that are stable on geologic timescales. *Ex situ* carbon mineralization can be done with silicate rocks and even alkaline industrial byproducts.4 Calcium and magnesium are found in many other materials that are often considered the 'wastes' of industrial processes: mining wastes, steel slag, air pollution control residue, fly ash, and many other industrial wastes are abundant in magnesium and/or calcium and can be used as feedstocks for *ex situ* mineralization processes. At the Clean Energy Conversions Lab, we research carbon mineralization as a method of carbon storage in two projects: the first project loops Mg and Ca oxides that are highly reactive with CO2 to conduct direct air capture;5 the second leaches calcium and magnesium from mining wastes from carbonates.6 Our research into carbon mineralization extends beyond the lab as we consider how economics, mapping, life cycle assessments, and US policy can help deploy carbon mineralization on a broad scale.
