Or. And I’m just spit balling here. Plant super long lived trees. Redwoods live for >200 years. Eucalyptus grow very quickly and might be a good option too.
I can do you one better. Plant those trees and when their growth (in terms of sequestered C02/year) start to plateau you cut them and either use them for construction or bury them in places where the conditions are right for coal formation. Since we understood the "coalification" process we can also manufacture such sites close to where said trees are planted.
In the latter case you bury the trees and forget them because accelerating coal synthesis is energy intensive, and so you can't really reuse that coal as it would be a net negative in our energy budget.
So you either are sequestering C02 and using it to create houses that will be around at least few decades (and in the process maybe also decrease the material cost of such constructions) or permanently sequester it in a way that only a few % of the sequestered C02 gets back into the atmosphere.
I can't find anymore the article that explains what I mentioned, but the issue is that is not economically profitable (is costs $$$ without generating a return with the current laws). However, I believe that if you account the damage climate change is doing around the world it is.
