Direct Air Capture, or DAC, represents a significant shift in our approach to managing carbon dioxide emissions. Unlike traditional carbon capture and storage, CCS, that targets point sources of emissions like factories or power plants, DAC can be set up anywhere, it doesn’t need to be in the same place or even at the same time as emissions are occurring.
The flexibility be able to suck carbon out of the air anywhere is nice, but that flexibility comes at a big cost in terms of both money and energy use.
In this video we dive into the world of DAC: how the technology works, who’s doing it and the controversial role of DAC in our mission to combat climate change.
