This sums it up pretty well

Literally all ideas about carbon capture are quickly revealed to be cynical greenwashing if you think about one simple thing: how much CO2 do we need to store to offset global emissions?

The answer is that we need to store almost 40B tonnes of CO2, or around 10B tonnes of C if we break that down, every year. That's something on the order of 1500 great pyramids of Giza (which weighs 6M tonnes) worth of carbon every year.
