Cost of direct air carbon capture to remain higher than hoped

ETH researchers concluded the cost of removing large quantities of CO2 from the air will fall in the medium term, but not as much as previously hoped.


ETH spin-off Climeworks operates a plant in Iceland that currently captures 4,000 tonnes of CO2 a year, at a cost per tonne of between 1,000 and 1,300 dollars. But how quickly can these costs come down as deployment increases?

ETH researchers have developed a new method that provides a more accurate estimate of the future cost of various DAC technologies. Rather than the oft-cited figure of 100 to 300 US dollars, the researchers suggest the costs are more likely to be between 230 and 540 dollars.
