I mean, what could go wrong?
/sarcasm
I guess a release of a bleep-ton of CO2 all at once.

I though this was a storage approach involving diffusion without a hard boundary, not a pressure dome like natural gas storage. No?
So it would just seep out?

Not that big sudden CO2 burps are harmless.
This one springs to mind https://en.wikipedia.org/wiki/...
The design of the degassing system is one of the coolest engineering ideas I've seen in ages.
The reduction in the CO2 concentration is powered by the CO2 concentration itself.
