摘要： A plurality of carbonation plots are positioned in communication with atmospheric carbon dioxide to facilitate sequestration thereof via ambient weathering. The carbonation plots include a composition rich in metal oxides, which are positioned within the environment, such as on non-arable land, and exposed to the environment to react with carbon dioxide in the air and form metal carbonates. After about one year of exposure, the composition is recollected and calcined to produce a carbon dioxide stream and replenish the metal oxides, which can be redistributed in the carbonation plots to sequester additional carbon dioxide. The systems and methods of the present disclosure enable capture and redistribution of carbon dioxide for industrial-scale uses for very abundant quarry minerals and enable large-scale low-cost carbon capture projects for municipalities or corporations. CO2 removal from air via these methods and systems have a similar or lower cost than CO2 removal using DAC with synthetic sorbents or solvents.

摘要： Embodiments described herein relate to systems and methods of CO2 uptake. In one aspect, a method includes applying heat to a calciner to decompose a carbon-containing stream to a gas stream and a stream of a carbonation medium, the gas stream including CO2. The method further includes sequestering and/or utilizing the gas stream, feeding the stream of the carbonation medium to a carbonation station, contacting the carbonation medium with ambient air at the carbonation station, such that the carbonation medium adsorbs CO2 to form the carbon-containing stream, during the contacting, adding a water stream to the carbonation medium at intervals of about 30 minutes to about 72 hours, and feeding the carbon-containing stream to the calciner. In some embodiments, adding the water stream is via misting and/or spraying.
