Adsorption-based direct air capture (DAC) of carbon dioxide, using chemisorbents like solid amines, has been widely recognized as a sustainable measure to contain atmospheric CO₂ concentrations. However, the productivity and economic viability of DAC have been compromised by the high energy consumption for regenerating the adsorbents. Here, the authors show that by synergistically harvesting water and carbon dioxide from the atmosphere, they can regenerate the unit using in situ vapor purge at low energy and capital cost.
