Carbon dioxide removal does already exist, but only at the tiniest of scales. We're talking a few thousand tons a year. But what might a future where we're successfully capturing billions of tons of carbon dioxide from the air each year, actually look like? After all, those are scales carbon capture needs to be operating at if it's truly to play a part of the solution to climate change. But it is not without challenges.
Where would all this CO2 be stored? What might the carbon capture machines look like? And how are we going to get this whole carbon capturing business off the ground in the first place?
We explore these and other questions in this third episode in our four-part series looking at Carbon Dioxide Removal.
