It's been a few years since I've studied carbon sequestration as well. It was for my geologic thermodynamics class. And you're close, it's calcite (calcium carbonate, CaCO3), either that or you're correct, lol.

In the article, they discussed capturing exhaust, but they also talked about pulling the carbon gasses directly from the atmosphere. That's the part I'm most skeptical about.

We gotta make ot work somehow, though. Even if we 100% stopped production of greenhouse gasses today we're still looming on the edge of climate disaster with the CO2 already in the atmosphere. The normal biological and geological processes that sequester CO2 move too slowly to save us.

We gotta scale that shit up.

I agree that we are facing the greatest crisis that humanity has ever faced, and we're sprinting towards that cliff.

I'm all for investing into large scale production of technology that pulls carbon gasses from the air. I just want to be sure this technology works as advertised and results in a net negative of atmospheric carbon. The last time we need to do is scale up something that doesn't work.

There's a lot we can do to mitigate the upcoming climate crisis, but most of the biggest impacts we can make (such as reducing carbon emissions) gas a lot of resistance. I'm not very optimistic that humanity as we know it will survive past this great filter.
