Storing CO2 into a depleted gas field is likely to last a lot more than a few decades. Hint: for how long did the natural gas stay in there? There are CO2 sinks which, given no emissions, can reduce CO2 concentration back to pre-industrial levels in a few centuries. Then it won't matter as much (if at all) when increased quantities of CO2 are released from their storage.
