Agree, carbon capture process is quite efficient now. I’m working on (pretty big) company doing Carbon Capture and Sequestration. The idea is to use empty oil&gaz reservoir to inject back carbon where it comes from. So there are several advantage:
The land is already messed up by former drilling platerform. No need to shave another forest to create a facility
No waste to handle, as the captured carbon is injected in the underground. We also study the possibility to inject other kind of waste, like domestic ones.
Simplified process as we can keep Co2 in gaz state to inject back in former natural gaz reservoir. Not even needed to extract carbon to solodify it.
Yes, trees are much more efficient and eco-friendly, but sometime we cannot just plant billions of trees. Whereas a CCS facility is relatively small compared to a whole forest.
I think as long as they throw a 10 lb bag of sugar down the hole before they start pumping then you don’t have to worry about it accidentally becoming a diet Coke.
Geological reservoirs are thousands metter depth and several dozen of km wide. Pressure is
a few MPa, and temperature hundreds of °C. Condition are so extrem that filling them with gaz barely change anything. Especially if they were already filled with gaz dozen years ago.
Furthemore, they are not big vacum like most people imagine. It’s more like giant spongy rock, like sand. It’s not a baloon you inflate or deflate.
CCS facilities are not in competition with forest. It’s a complementatry solution. If you manage to capture carbon next to poluting factories, you don’t spread Co2 on the atmosphere, waiting it to be captured by a forest the other side of the globe. And they can be powered by solar panels.

That seems like a disaster waiting to (re) happen, what’s your thoughts on that?
What do you mean ?
Carbonating a void underground seems like a bad plan. God help us if Mentos get down there.
And OP was talking about trees.
