Do you have any links on research on that? Serious question.

Yes.

For example:

Peter Kelemen has written a lot of papers on this topic.

Here is a more recent paper that I wrote together with Peter and others currently in review:

https://eartharxiv.org/repository/view/9651/

This is more about the mechanics of how the rock breaks to allow fluids to move around.

And here is another paper currently in review that we coauthored about how we know there’s gas moving in the system and therefore hydrogen is being produced:

Tbh I have no idea why we didn’t submit these to arXiv instead of these other preprint servers.

Someone proposed to make giant beaches of malachite and let the sea break the rocks. Malachite has two -OH that can be replaced by a CO3= and so capture the CO2.

I can't find a good link now, but at least it's the only method I know where it's not obvious that requires a huge amount of energy that makes the whole process net negative.
