CO2 as a C1 feedstock is receiving increasing attention, but it typically exists in dilute or impure streams. The capture and conversion of CO2 to fuels or chemicals using carbon-neutral energy mitigates carbon emissions when CO2 is captured from point sources and results in net or negative carbon emissions when CO2 is obtained by direct air capture. Additionally, CO2 capture and conversion steps are typically viewed as separate processes that optimize either capture and concentration or catalytic conversions of pure streams of CO2.
