Algae or hemp. Hemp stores 85% of the carbon in its roots, so you can use the rest of the plant. Just collect the roots and compress them to a density that will NOT float and dump the root cubes into the Mariana Trench. That carbon will be trapped for a few tens to hundreds of millions of years. Also one acre of hemp pulls 10 times more carbon out of the air that one acre of trees does per harvest, and you can harvest the hemp 4 times a year as opposed to once every 60 years.
Or throw them into a strip mine or oil well seal it up. Not like we don't have a ton of giant holes in our ground after a century of fossil fuel extraction.
I would be worried about seepage into and out of those holes, but I suppose it is unlikely to turn into something toxic...
Yeah, algae has problems with sensibility to temp and bacteria and so on. And my duvet cover out of hemp thermo-regulates itself, no sweat.
