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.

We also consider the economic, political, social and environmental ramifications that will arise with the availability of an affordable air capture technology. It is our long-term goal to make the CNCE the intellectual leader in this new field of sustainable energy infrastructure design critical to achieving a carbon negative energy economy.

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.

Center for Negative Carbon Emissions — Research Program

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. We have demonstrated a moisture swing sorbent cycle for capturing carbon dioxide (CO2) from air. The sorbent, an anionic exchange resin, has been shown to absorb CO2 when it is dry, and to release it again when exposed to moisture. We aim to advance this technology as it applies to closing the carbon cycle with carbon recycling, reducing atmospheric concentration through CO2 disposal, and the economic and policy considerations from its availability. Our interdisciplinary research approach includes:
>> Demonstration and development of prototype technologies to close the carbon cycle and create net negative emissions
>> Advancement of fundamental sciences supporting this new technology base
>> Systems analysis and engineering studies of rapid transition to new energy infrastructures
>> Models of the underlying mechanisms within air capture technology
>> Study of the interactions of these new technologies with policy development and of the societal implications of these changes
>> Analysis to determine the optimal positioning of these technologies to best serve societal needs.

The Intergovernmental Panel on Climate Change (IPCC) asserts that limiting global warming to 1.5˚C could avert the most catastrophic effects of climate change. In its recent report, it laid out four means of achieving this —and all of them rely on removing carbon dioxide from the atmosphere. This is because even if we cut most of our carbon emissions down to zero, emissions from agriculture and air travel would be difficult to eliminate altogether. And since carbon dioxide that’s already in the atmosphere can affect climate for hundreds to thousands of years, the IPCC maintains that carbon dioxide removal (CDR) technologies will be critical to get rid of 100 to 1000 gigatonnes of CO2 this century.

How can carbon dioxide be removed? There are a variety of CDR strategies, all in different stages of development, and varying in cost, benefits and risks. CDR approaches that employ trees, plants and soil to absorb carbon have been used at large scale for decades; other strategies that rely more on technology are mostly at the demonstration or pilot stages. Each strategy has pros and cons.

NOTE: FrackCheckWV has multiple concerns that this Center is not based upon practical principles. Carbon dioxide removal costs are high, storage and transport are expensive, and ultimate uses are limited. We are convinced that fossil fuels need to be phased out in the near term, i. e. ASAP. DGN
