Biochar is also alkaline. Why not dump it in the sea? Then we get a two-fer: capturing carbon and de-acidifying the ocean.

Plenty of empty tankers leaving US shores, I'm sure the captains wouldn't mind having a heavier ship, and it shouldn't hurt the fuel efficiency much at all. But, mechanically, how to empty it into the sea? Put conveyers on deck and dump it over the side as you go?

Or pump it in and out as a slurry. That's typically the most convenient way to handle granular solids.
