While it's probably worth doing, it is a high-tech process subject to all the problems associated which are many. A low tech approach would be biochar.

It may be better to take carbon from biomass instead of atmospheric gas, IDK.

A high-tech approach to biochar would be Cool Planet. Whelp, it looks like Cool Planet was acquired by National Carbon Technologies last June.
