To be clear: carbon capture like this is a tiny and expensive part of what needs doing over the next few years
It’s getting a lot of support and publicity in large part because it’s backed by the oil industry, which is trying to create social permission for continued extraction and burning on a much larger scale than the removal.
What if excess solar was used for it instead?
What if we used that energy in a more efficient way to directly prevent CO2 emissions? That will result in x times more CO2 saved with the same resources.
Not sure how efficient CCS tech currently is, but it will be far from efficient.
Oh we’re playing the what if game? What if this technology becomes super efficient and is better than your imaginary technology? Check mate.
It is like optimizing recuperation in a car. You are still driving around in a car, the basic issue is still there. There a far better solutions. That is not a “what if” question.
