Offshore Volcano Holds Potential for Massive Carbon Storage
An extinct offshore volcano in Portugal could potentially store 1.2-8.6 gigatons of carbon dioxide, representing 24-125 years of the country’s industrial emissions, according to a new study. The method involves ‘in situ mineral carbonation,’ where CO2 reacts with specific rock elements to create new, safely stored minerals. This efficient and quick method could pave the way for using other offshore volcanoes globally for carbon capture and storage.
