Deep dives
The Role of Direct Air Capture in Sustainable Aviation
Direct air capture (DAC) technology is emerging as a vital component for achieving sustainable aviation, especially in addressing hard-to-abate emissions. This technology captures CO2 directly from the atmosphere and is crucial for offsetting emissions produced by the aviation sector. A significant part of the conversation is centered around the integration of DAC with sustainable aviation fuels (SAF), where captured CO2 can serve as a feedstock combined with hydrogen to create cleaner fuels. This synergistic relationship suggests that both DAC and SAF are necessary for the aviation industry to reach its climate targets, allowing the airlines to claim a more comprehensive net-zero status.
