    I imagine that suddenly all the co2 stored as gas underground could suddenly come out and being odorless, kills the whole neighboring town

      Natural gas is also odorless and able to displace oxygen so I don’t see how it being CO2 underground instead of natural gas changes anything from a risk perspective. Maybe because the molecules are smaller and thus more prone to leaks? I’m admittedly way out of my depth here.

        Methane is lighter than air and goes up while co2 is heavier than oxygen and stays down. I don’t know maybe in case of some disaster where water leaks in the well and then pushes out the co2

        I wouldn’t want to live nearby in both cases anyway

      I mean, all that methane coming out would probably be at least as bad, and the cavity had previously been filled with methane.

      It’ll be a cavern deep under a lot of rock. If it can contain methane for zillions of years, I imagine that it can contain carbon dioxide.
