Jan 29, 2024 · Enhanced weathering (EW) involves spreading finely ground rock particles, often silicate rocks like basalt, to increase the rate of weathering and facilitate carbon dioxide removal. It is a type of geoengineering (learn …
Enhanced weathering - Wikipedia
Enhanced weathering, also termed ocean alkalinity enhancement when proposed for carbon credit systems, 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 carbonate minerals or ocean alkalinity. The latter also slows ocean acidification.
