The kelp elevator example caught my attention because oceans are so large ( operations wouldn't be competing for land), the US Navy is the most funded branch, and the resulting cattle feed emits less methane. It's less of a permanent sequester and more of a resource loop modification. CO2 is a useful resource in this context (even though there is much talk about limiting meat consumption, which could limit the market). There are additional examples in the article, but they have more to do with deflecting sunlight. In this case, could we still have lots of atmospheric CO2 (to be used as a resource) while still reducing temperatures and regenerating white ice?
