“…In addition, DAC productivity and energy demand is affected by ambient temperature and relative humidity, which differ by time and location. [67][68][69] The current study is limited in that regard as it is based on nominal annual average productivity and energy demand in test locations. In the BCS, DAC experiences a major capex reduction and energy efficiency gain by 2030.…”

“…Recently, additional research efforts have been devoted to DAC at cold temperatures to promote the application of DAC across a wider geographical expanse. 15,[42][43][44] In practical DAC units, it is essential to ensure a low pressure drop in the DAC unit to reduce the energy consumption in moving the ambient air and reduce the associated operating costs. [45][46][47][48][49][50][51] Therefore, it is crucial to select an appropriate contactor conguration that can lead to a minimal pressure drop.…”

Direct air capture (DAC) is a sustainable technology to alleviate the greenhouse effect and a reliable pathway to acquire inexhaustible CO2 for the production of costly chemicals and energy products. Current DAC technologies with amine‐related sorbents rely on chemisorption, while they consume intensive energy for CO2 release and sorbent regeneration by heating. Developing new DAC processes with weak, reversible adsorption can substantially reduce the regeneration energies. Herein, the design of CO2 breathing paper (CBP) is demonstrated toward spontaneous CO2 extraction from ambient air and solar‐driven regeneration. The CBP is fabricated by coupling 2‐ethyl‐4‐methylimidazole to carbon nanotube paper on the basis of density functional theory calculations. At ambient conditions, CBP spontaneously captures atmospheric CO2 with a capacity of 0.14–1.75 mmol g–1 at 0–35 °C through non‐covalent electrostatic interaction. Upon exposure to sunlight, all adsorbed CO2 can be released and converted to concentrated gas for storage. Attractively, the efficiency of solar‐driven CO2 release is much higher than the traditional temperature‐swing method owing to the IR sensitivity of CO2. Besides the reversibility, the mild conditions also ensure the durability of CBP. These findings suggest that the CBP is a promising candidate for cost‐effective DAC.
