1. A process for production of high purity CO, comprising the steps of:
providing a first CO2 gas with a purity above 90% to a device comprising at least one Solid Oxide Electrolysis Cell and comprising a gas separation unit; providing a current to at least one Solid Oxide Electrolysis Cell and producing a second gas comprising CO in said Solid Oxide Electrolysis cell by means of CO2 electrolysis providing said second gas to the output gas separation unit; and operating said gas separation unit at temperatures between 0° C.-50° C., and thereby producing a third output gas comprising CO with a purity above 90%.
