🚨NEW STUDY🚨

🌋 A recent study by @Olenellus & @GambixPT published in @geosociety found that “an extinct #volcano off the shore of Portugal could store as much as 1.2-8.6 gigatons of CO2, the equivalent of 24-125yrs of the country’s industrial emissions.”

“Doing so would rely on a method known as in situ mineral #carbonization, which works when the CO2 taken from the air is pumped deep underground.”

“Once in the bowels of this extinct volcano, calcium, magnesium, and iron react to the incoming carbon dioxide to form calcite, dolomite, and magnesite, trapping the CO2 forever in a rocky prison.”

“Doing it in the Fontanelas volcano, 60 miles off the coast of Portugal presents several advantages:
1️⃣ The mountainous structure of the volcano would make drilling into it easy relative to other in situ mineral #carbonization drilling projects.”

2️⃣ “Volcanic #basalt tends to contain high percentages of iron, magnesium, and calcium.”

3️⃣ “It’s near at hand to the shore and doesn’t take up any land space in the country.”

The joint American-Portuguese team of scientists publishing for the @geosociety also found that “the rocks of the Fontanelas volcano contained high levels of #carbonates—indicating that the processes of in situ #carbonization were already occurring naturally.”

Furthermore, “the rocks dredged up were 40% porous, meaning a high amount of space exists for the #injection of CO2.”

The authors suggest that “there are likely other undersea volcanoes that countries could use as CO2 landfills.”
