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.
Unless and until emissions are reduced to a tiny minuscule fraction of current ones, carbon capture will not do even one iota to help with global warming.
