Startup Graphyte is joining efforts to store biomass underground. Its technique is one of many that aims to use nature’s scraps to help the world decarbonize.
The algae farm thing is completely experimental, and not at all clear that it will work. Oceans contain a lot of scavengers, who would love to eat pretty much anything you release.
Deep in the sea it should not decompose, otherwise there wouldn’t be efforts to grow gigantic Alge farms and sink them to the bottom of the sea.

Thats why its important where its sunken and how deep it is.
And how it’s contained, and that you monitor it, both of which are hard in the ocean.
You would probably have to send down a submarine from time to time, but from energy levels its probably still more efficient than burying it.
