A process for methanation comprising a first region for flowing a stream over a solid oxide electrolysis cell. In this first region the stream consists of CO2, H2, and H2O, the stream is converted into a first conversion stream, and the solid oxide electrolysis cell is enhanced with a methanation catalyst. The process also has a removal region connected to the first region wherein the removal region is able to flow the first conversion stream away from the solid oxide electrolysis cell.
