Vesta

About

Vesta (formerly Project Vesta) is a San Francisco-based Public Benefit Corporation developing “Coastal Carbon Capture,” an ocean alkalinity enhancement approach that places olivine sand in coastal waters. The company has conducted pilot deployments in Southampton, NY (2022, 500 cu yd) and Duck, NC (2024, 8,200 metric tons of olivine), the first standalone ocean-based CDR pilot permitted in the US.
