• Herein a non‐precious transition‐metal catalyst system for the selective synthesis of dialkoxymethane ethers from carbon dioxide and molecular hydrogen is presented. The development of a tailored catalyst system based on cobalt salts in combination with selected Triphos ligands and acidic co‐catalysts enabled a synthetic pathway, avoiding the oxidation of methanol to attain the formaldehyde level of the central CH2 unit. This unprecedented productivity based on the molecular cobalt catalyst is the first example of a non‐precious transition‐metal system for this transformation utilizing renewable carbon dioxide sources. Stand by me: Dialkoxymethane and oxymethylene ethers are becoming increasingly important as fuel or fuel additives. A non‐precious‐metal based catalytic system opens a sustainable synthetic pathway to these liquid energy carriers via the combined utilization of bio‐based feedstocks and CO2 as carbon sources together with “green hydrogen” from water electrolysis (“bio‐hybrid fuels”).
