Permanent CO2 removal through enhanced weathering

Silicate is the first enhanced weathering company to leverage the massive carbon removal potential of limestone. Weathering reactions between carbonic acid and minerals create bicarbonate, a stable form of inorganic carbon. When transported to the ocean, bicarbonate has a residence time of 80,000 years, constituting a carbon sink on climate relevant timescales. However, quantifying carbon removal by these reactions is complex, and an accurate, precise, internally consistent approach for measurement is integral to scaling enhanced weathering. Silicate measures carbon dioxide removal across solid, liquid, and gaseous phases by conducting soil sampling, soil water sampling, and soil-air gas flux testing. This video details our work in Wexford, Ireland, since 2021 to measure carbon dioxide removal through limestone enhanced weathering. Directed and filmed: ‪@DeclanColfer‬
