Air Capture
Direct capture of CO2 from ambient air.
|
Essentially all my work on air capture is now wrapped up in Carbon Engineering www.carbonengineering.com a startup company commercializing air capture technology. I do not maintain a separate academic effort on air capture. The pace of engineering development within Carbon Engineering is rapid and we will only occasionally publish in the academic literature.
