Basalt covers most of the oceanic floor and about 10% of the continents.

“The largest storage potential lies offshore, where theoretically all CO2 from burning of fossil fuel carbon
could be stored with long-term advantages for safe and secure CO2 storage in the mid-ocean ridges.“

Iceland is the largest landmass above sea level at the mid-ocean ridges, mostly (~90%) made of young
and fractured basaltic rocks
