CO2 to C2 value chain. Electrocatalytic conversion of CO2 to oxalic acid (direct or via formic acid or the corresponding salts) and value chain which can derive from the further reduction of oxalic acid. The graph indicates the approximated market size and product value, with the bubble size corresponding to market value (27,6 M$/y for product 5, ethylene glycol). Reproduced with permission from ref.
