Mineral CO2 sequestration by environmental biotechnological processes.
CO2 sequestration may be an avenue to mitigate climate change. CO2 sequestration by mineral carbonation can be achieved by the reaction of CO2 with alkaline silicates. Here, we evaluate how alkaline silicate mineral-based CO2 sequestration can be achieved using environmental biotechnological processes. Several biotechnological processes rely on the sequence of (i) an acid-producing reaction suc...
متن کاملSequestration of Martian CO2 by mineral carbonation
Carbonation is the water-mediated replacement of silicate minerals, such as olivine, by carbonate, and is commonplace in the Earth's crust. This reaction can remove significant quantities of CO2 from the atmosphere and store it over geological timescales. Here we present the first direct evidence for CO2 sequestration and storage on Mars by mineral carbonation. Electron beam imaging and analysi...
متن کاملCO2 Mineral Sequestration Studies in US
Carbon sequestration by reacting naturally occurring Mg and Ca containing minerals with CO2 to form carbonates has many unique advantages. Most notably is the fact that carbonates have a lower energy state than CO2, which is why mineral carbonation is thermodynamically favorable and occurs naturally (e.g., the weathering of rock over geologic time periods). Secondly, the raw materials such as m...
متن کاملDeveloping a Mechanistic Understanding of Lamellar Hydroxide Mineral Carbonation Reaction Processes to Reduce CO2 Mineral Sequestration Process Cost
The potential environmental effects of increasing atmospheric CO2 levels are of major worldwide concern. One alternative for managing CO2 emissions is carbon sequestration: the capture and secure confinement of CO2 before it is emitted to the atmosphere. Successful technologies must be environmentally benign, permanent, economically viable, safe and effective. As a result, their timely developm...
متن کاملUse of Forced Mineral Trapping for Sequestration of CO2
Among the options being considered to help mitigate anthropogenic CO2 emissions is carbon sequestration in depleted oil or gas wells, coal seams, and deep underground saline formations. One of the uncertainties that must be addressed with respect to geologic sequestration is the long-term risk associated with storage of large quantities of CO2 in the subsurface. Rapid release of CO2 could occur...
