WebFeb 19, 2024 · As natural rock weathering absorbs around 0.3% of global fossil fuel emissions, enhanced weathering can provide a boost to remove even more CO2 from … Enhanced weathering is a process that aims to accelerate the natural weathering by spreading finely ground silicate rock, such as basalt, onto surfaces which speeds up chemical reactions between rocks, water, and air. It also removes carbon dioxide (CO2) from the atmosphere, permanently storing it in solid … See more Enhanced weathering has been proposed for both terrestrial and ocean-based carbon sequestration. Ocean methods are being tested by the non-profit organization Project Vesta to see if they are environmentally … See more Weathering is the natural process of rocks and minerals dissolving to the action of water, ice, acids, salts, plants, animals, and temperature … See more To overcome the limitations of solution saturation and to use natural comminution of sand particles from wave energy, silicate minerals may be applied to coastal environments, although the higher pH of seawater may substantially decrease the rate of dissolution, … See more In a 2024 techno-economical analysis, the cost of utilizing this method on cropland was estimated at US$80–180 per tonne of CO2. This is comparable with other methods of … See more Enhanced weathering was initially used to refer specifically to the spreading of crushed silicate minerals on the land surface. Biological activity in soils has been shown to … See more The enhanced dissolution and carbonation of silicates ('mineral carbonation') was first proposed by Seifritz, and developed initially by Lackner … See more Where abundant electric surplus electricity is available, the electrolytic dissolution of silicate minerals has been proposed and experimentally shown. The process resembles the … See more
