Direct air capture (DAC) can provide an impactful, engineered approach to combat climate change by removing carbon dioxide (CO2) from the air. However, to meet climate goals, DAC needs to be scaled at a rapid rate. Current DAC approaches use engineered contactors filled with chemicals to repeatedly capture CO2 from the air and release high purity CO2 that can be stored or otherwise used.

Authors Justine Davids and Katherine Vaz Gomes Earth’s biosphere, unaided, cannot fix the climate problem that humans created and continue to disregard. Most climate stabilization scenarios require carbon dioxide removal (CDR): the world is waking up to the fact that reducing emissions is no longer sufficient and that we must simultaneously work to remove carbon dioxide (CO2) from the atmosphere. CDR is no longer a last resort, but an urgent necessity.
