This study did not consider what happens to carbon dioxide after it is captured but Jacobson suggests that most applications today, which are for industrial use, result in additional leakage of carbon dioxide back into the air. People propose that carbon capture could be useful in the future, even after we have stopped burning fossil fuels , to lower atmospheric carbon levels.
Even assuming these technologies run on renewables, Jacobson maintains that the smarter investment is in options that are currently disconnected from the fossil fuel industry, such as reforestation—a natural version of air capture—and other forms of climate change solutions focused on eliminating other sources of emissions and pollution.
These include reducing biomass burning, and reducing halogen, nitrous oxide and methane emissions. It delays action. In fact, carbon capture and direct air capture are always opportunity costs.

To change that reality, there must be economic costs to releasing carbon dioxide pollution into the atmosphere. Hence, even the best carbon capture technology will be useless if the world is not willing to put a price on carbon," Berend Smit , a Professor of Chemical and Biomolecular Engineering at the Department of Chemical and Biomolecular Engineering, at the University of California, Berkeley, tells CNBC by email.
His research focuses on finding the optimal material for carbon capture. In the meantime, scientists and researchers are working to make current carbon capture technologies better. Smit is also working on how to use a kind of sponge "with a strong affinity for carbon dioxide," he says. Once the material is saturated with CO2, we need to heat it, pure CO2 comes out, which we can then store.
The sponge is empty and we can start over again. Lackner has developed a free-standing device to take carbon dioxide out of the air. Fundamentally, it all comes down to money. Skip Navigation. Key Points. While trees and other plants can remove some carbon dioxide from the atmosphere, most climate change experts agree we can't plant enough, fast enough, to do the job alone.
Carbon capture technology has been around for decades, and is used to strip carbon out of factory emissions as well as remove carbon that's already in the air. But it's expensive, and until the cost of releasing carbon into the air rises, there's little economic incentive to use it. People tend to vegetables growing in a field as emission rises from cooling towers at a coal-fired power station in Tongling, Anhui province, China, on Wednesday, Jan.
