"Eric Matzner, who co-founded the nonprofit Project Vesta this year, intends to mine tons of a soft, crumbly green volcanic stone called olivine, grind it into pebbles and spread it on shorelines, coves and beaches, where the wave action will weather it down like a river sculpts gravel."

"This study suggests simultaneous multiple energy productions and CO2 storage can be realized by olivine weathering process when using a CO2-rich hydrothermal condition."

"Project Vesta is a project to remove carbon dioxide (CO2) from the atmosphere and oceans by accelerating the weathering of a type of rock called olivine. When olivine interacts with water and the CO2 dissolved in it, a chemical reaction (called weathering) occurs that creates a bicarbonate solution that marine animals like corals use in their shells. The CO2 remains locked in that form and eventually settles as sediment or turns to limestone rock on the sea floor."

"This study aimed to characterise how olivine can weather in seawater, to elucidate the role of secondary precipitation and to ascertain the efficiency in terms of molar CO₂ removal per mole of olivine dissolution. Geochemical thermodynamic equilibrium modelling was used, which considered both the variable mineralogical composition of olivine and the kinds of secondary precipitates that may be formed. The advantage is that such an approach is independent from local or regional factors as temperature, related kinetics, mineralogy, etc. The results show that the efficiency falls when secondary precipitates are formed."
