Technology Review: Carbon-Capturing Rock
Basically, when tectonic plates bump into each other they crinkle and wrinkle and separate and otherwise open up the crust of the earth. New rock layers that were underground get exposed to the air. That rock (Peridotite) is pretty good at carbon sequestration as it converts carbon dioxide in the air into calcium and magnesium carbonate.
They think the can speed up the sequestration process by heating up the rock, fracturing it, and drilling it. They could then pump carbon dioxide from power plants directly into the rock.
It sounds interesting. Good find Michaelangelica.
