There is a huge amount of talk about things like this or CarbFix which all seem secondary to the "capture CO2 at some generic capture point and pump it into a saline aquifer" approach which seems to be pretty scalable.

Even though the technology is on the shelf it's not being deployed largely because there is no financial incentive to do so... Yet the widespread use of this technology really needs to be happening now if we want any of these carbon capture things to happen.
