Air capture technology is the collection of tools intended to manage and reduce the buildup of carbon dioxide (CO2) in the atmosphere. CO2 is the largest and most persistent heat-trapping gas and excess man made CO2 emissions can cause potentially catastrophic and irreversible damage to our earth systems. While natural forces will remove some of the CO2 that is emitted to the atmosphere, a large fraction of today’s emissions will linger for thousands of years.Learn More
In order to meet the challenge of transitioning to a carbon negative energy economy, the Center for Negative Carbon Emissions (CNCE) focuses on developing the next generation of carbon management technologies.Read more about our interdisciplinary research approaches.
The CNCE is directed by Dr. Klaus Lackner. His research interests include closing the carbon cycle by capturing carbon dioxide from the air, carbon sequestration, carbon foot-printing, innovative energy and infrastructure systems and their scaling properties, the role of automation, robotics and mass-manufacturing in downscaling infrastructure systems, and energy and environmental policy.CNCE Faculty & Staff
The Center for Negative Carbon Emissions (CNCE) is advancing carbon management technologies that can capture carbon dioxide directly from ambient air in an outdoor operating environment.
What are “negative carbon emissions”?
How does “carbon farming” work?
What do we do with excess carbon?
We’re not just aiming to bring carbon dioxide emissions down, we’re aiming to have negative carbon emissions — capturing more than we produce using our artificial “trees” and reusing it.
Take a look inside the CNCE as Dr. Lackner explains how carbon air capture technology works.
Like throwing trash into the street, each year we pump tons of carbon dioxide into the atmosphere. Our Center is developing technology poised to collect and reuse our carbon while cleaning the air.
The ASU Center for Negative Carbon Emissions with its commercial partner Silicon Kingdom Holdings Ltd., is testing a prototype technology that would remove carbon dioxide from the air through the use of “mechanical trees.” Widespread use of such a technology could help draw carbon dioxide out of the air and reduce global warming. The liquid CO2 collected by the tree can then be converted into a carbon neutral fuel or other useful chemical, or disposed of to cancel out present or past emissions. The specific design licensed to SKHL is an ASU innovation developed under SRP sponsorship. ASU and SKHL are the research and commercialization partners in this endeavor.
