You're right, there seems to be iron rich deep sea currents in some places that could be good opportunities for upwelling, especially if you had a carbon neutral way to do it.
There is also emerging technology for nitrogen fixing that could work - Electrocatalytic Nitrogen Reduction.
All this being said, if the goal is carbon sequestration building a viable business is going to be next to impossible.
The easiest way would be to use your renewable energy to pull bicarbonate out of the ocean directly with electrolysis, reverse-osmosis, whatever magic tech the wizards in MIT are cooking up.
Only then you've got the problem of what to do with it all once you've got it on hand.

- chr1 2y agoCarbon sequestration is merely a side effect, the main goal is to have a wavebreaker and a park and a place to grow fruits, for a floating city. To bring nutrient rich water up and to generate energy in the process temperature difference between surface and deep water can be used [1]. So if this kind of tree is created, living on open sea can become cheaper and more pleasant than even living on a beach.

- the_sleaze_ 2y agoOk, I was misunderstanding. Ocean thermal energy conversion - I hadn't heard of this, this is awesome.
