the C02 thus stored, what do we do with it? bubbles for the perrier?
The basic principle of this storage is as follows: let's send back the CO2 where it comes from.
Let me explain: unlike short cycles like the growth of wood for example (the CO2 emitted by burning wood is that captured by the tree during its growth), the CO2 cycle of fossil fuels is a cycle on several Tens of thousands or even millions of years.
In fact, the CO2 released by petroleum, coal and the like is that which has been captured by plants which, following pressure, heat and time, have been transformed into petroleum or coal.
The concern is that this CO2 captured over thousands of years is massively rejected in a few decades. This is where the rub is: the current vegetation is not capable of trapping the equivalent of thousands of years of CO2 capture by plants. Hence the idea of returning this CO2 where it comes from: underground. to make it ... nothing !!!
It's just that it isn't in the atmosphere.
Is it clearer like this ???
