Vesta

Vesta is the company in An "antacid" to fight climate change that placed more than 8,000 metric tons of olivine on the sea floor near Duck, North Carolina, to test Olivine Carbon Removal and Ocean Alkalinity Enhancement.

The source treats Vesta as a field-demonstration case rather than proof that the method is ready. Vesta estimates the Duck project could remove and store about 5,000 tons of CO2 after project emissions, but the episode keeps that estimate inside unresolved questions about monitoring, scale, speed, marine-life impact, and coastal-restoration use.
