I feel like that’s just sensationalism to get more media attention. The existing clay is formed by tectonic activity over a long period of time and using lots of energy (ie the earth’s core moving tectonic plates). Any artificial manufacturing effort would require similar energy input and it’s highly likely it requires more energy to create the clay artificially than it was to burn whatever amount of carbon gets sequestered (just guessing based on thermodynamics). So I don’t see how this clay helps us. It might be more efficient to create new clay than our existing recapture techniques although I would be skeptical.
