Abstract
Methods and systems related to valorizing carbon dioxide are disclosed. A disclosed system includes a reverse water gas shift (RWGS) reactor, a carbon dioxide source connection fluidly connecting a carbon dioxide source to the RWGS reactor, an electrolyzer having an anode area and a cathode area, and a carbon monoxide source connection fluidly connecting the RWGS reactor to the cathode area. The RWGS reactor is configured to generate, using a volume of carbon dioxide from the carbon dioxide source connection, a volume of carbon monoxide in a RWGS reaction. The electrolyzer is configured to generate, using the electrolyzer and a reduction of the volume of carbon monoxide from the carbon monoxide source connection and an oxidation of an oxidation substrate, a volume of generated chemicals including hydrocarbons, organic acids, alcohol, olefins, or N-rich organic compounds.
