"Scientists are taking a harder look at using carbon-capturing rocks to counteract climate change, but lots of uncertainties remain."

"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."
