WebTerrestrial enhanced weathering, the spreading of ultramafic silicate rock flour to enhance natural weathering rates, has been suggested as part of a strategy to reduce global atmospheric CO2 levels. We budget potential CO2 sequestration against associated CO2 emissions to assess the net CO2 removal of terrestrial enhanced weathering. We … Web15 Feb 2024 · Using constraints for atmospheric vapor-transport over continents and terrestrial weathering fluxes, we find that the emergence of widespread transpiration and associated inland vapor recycling... Weathering is the natural process of rocks and minerals dissolving to the action of water, ice, acids, salts, plants, animals, and temperature changes. It is mechanical (breaking up rock—also called physical weathering or disaggregation) and chemical (changing the chemical compounds in the rocks). Biological … See more 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. … 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, … 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 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 has been proposed for both terrestrial and ocean-based carbon sequestration. Ocean methods are being tested by the … See more Enhanced weathering was initially used to refer specifically to the spreading of crushed silicate minerals on the land surface.
