Sea level rise and coastal erosion threatens our cities, communities, and valuable coastal infrastructure. The oceans are our largest carbon sink and naturally absorb CO2 and convert it into rock over millennia, but the rapid increase in atmospheric CO2 due to industrial activity has led to ocean acidification.
Vesta dramatically accelerates the ancient natural process of rock weathering for permanent CDR and shoreline protection. The company spreads olivine, an abundant natural mineral, in coastal areas. As olivine interacts with seawater, it generates alkalinity in the form of bicarbonate (baking soda). By integrating olivine sand into shoreline protection projects, Vesta can harness free wave energy to accelerate the carbon dioxide capture process and de-acidify the ocean. The process captures 20x more carbon dioxide than the extraction and transportation of the olivine emits. Deploying olivine on just 0.25% of global shelf seas could remove 1B tonnes of CO2 from the atmosphere.
