Abstract

The present invention relates to a method for producing a syngas mixture, comprising: removing CO₂ from air by exposing the air to a carbon depleted alkaline catholyte capturing solution, thereby obtaining a carbon enriched catholyte capturing solution comprising HCO₃^-; feeding the carbon enriched catholyte capturing solution comprising HCO₃^- to a catholyte compartment of an electrolyser which further comprises an anolyte compartment comprising an anolyte solution and a middle layer compartment provided between the catholyte compartment and the anolyte compartment and comprising a middle layer solution; electrolysing a first portion of the HCO₃^-, thereby forming a syngas mixture, and electrolysing the anolyte solution to produce protons (H⁺); migrating a second portion of the HCO₃^- from the catholyte compartment to the middle layer compartment, and migrating protons from the anolyte compartment to the middle layer compartment; acidifying the migrated HCO₃^- with the protons, thereby forming CO₂. The invention further relates to a system for performing such a method.
