Methods and systems related to the field of carbon capture and utilization are disclosed. Disclosed electrolysis reactors can have a cathode area having a cathode output and a cathode input for an input fluid and an anode area having an anode input and an anode output. The carbon input fluid contains carbon dioxide. The cathode area reduces an oxygen-containing species into hydroxide ions and reacts them with the carbon dioxide to form anions containing carbon. The anode area oxidizes one or more oxidizable species to generate a protonating species. The electrolysis reactors can have a third output for a carbon output fluid. The electrolysis reactors can begin to produce carbon dioxide from the anions containing carbon and the protonating species in response to a potential of less than 1.23 V applied across the cathode terminal and the anode terminal.
