Integration of thermochemical water splitting with CO₂ direct air capture.

ABSTRACT: Renewable production of fuels and chemicals from direct air capture (DAC) of CO₂ is a highly desired goal. Here, we report the integration of the DAC of CO₂ with the thermochemical splitting of water to produce CO₂, H₂, O₂, and electricity. The produced CO₂ and H₂ can be converted to value-added chemicals via existing technologies. The integrated process uses thermal solar energy as the only energy input and has the potential to provide the dual benefits of combating anthropogenic climate change while creating renewable chemicals. A sodium-manganese-carbonate (Mn-Na-CO₂) thermochemical water-splitting cycle that simultaneously drives renewable H₂ production and DAC of CO₂ is demons
