There's been quite a bit of work on enhanced weathering (google the phrase). Even powered by coal and diesel, it's entirely feasible at global scale, provided we are willing to blanket a fairly large area of sea with rock flour.
Heirloom's approach, turn limestone into quicklime and then let the quicklime turn itself back into limestone, is different, and I don't know how the energy economics work out for it.

- diogenes4 3y agoThe ocean is a very large place, and much of the floor is nearly barren of life (compared to coastal waters anyway, and certainly in terms of biomass). Furthermore benthic storms already cause a great deal of turbulence on the bottom; i don't think problems are obvious. Granted, i have similar concerns about efficiency, but we need any wins we can find.
