Deep dives
The Importance of Direct Air Capture
Direct air capture (DAC) is seen as a critical technology in the fight against climate change, pulling carbon dioxide from the atmosphere to offset ongoing emissions. This method aims to help achieve net-zero emissions by 2050, as outlined by the Paris Climate Agreement, while addressing the reality that fossil fuels may still be used beyond that point. The current technologies for DAC face significant hurdles, including the need for substantial energy to operate and the requirement for safe transportation and storage of the captured carbon. Despite early successful prototypes, commercial implementation of DAC is limited, highlighting both the potential and the challenges that remain in large-scale deployment.
