A few centuries kicks the problem down the road a long way. If we successfully sequester enough carbon to prevent any horrific consequences of energy generation until, say, 2300, well, by 2300 people may well have plenty of additional options to deal with the carbon. Or at the least they'll probably be able to just once again sequester it through the same techniques. Or else global warming will be the least of humanity's problems in 2300.
