Carbon dioxide removal does already exist, but only at the tiniest of scales. But what could a future where we're successfully capturing billions of tons of carbon dioxide from the air each year, actually look like? Where would all the 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? We explore these and other questions in this 3rd episode in our series looking at Carbon Dioxide Removal. (Pictured: an artist's illustration from the Canadian company Carbon Engineering depicting what a future carbon capture installation might look like)
