Process for the co-production of methanol and ammonia in parallel comprising the steps of (a) providing a hydrocarbon feed stock; (b) preparing a separate hydrogen stream and a separate oxygen stream by electrolysis of water; (c) preparing a separate oxygen stream and a separate nitrogen stream by separation of air; (d) introducing at least part of the separate oxygen stream from step (b) and at least part of the separate oxygen from step (c) into an autothermal reformer; (e) in the autothermal reformer autothermal reforming the hydrocarbon feed stock from step (a) to a methanol synthesis gas comprising hydrogen and carbon oxides; (f) converting the methanol synthesis gas to raw methanol in a methanol synthesis stage; and in parallel (g) introducing the at least part of the separate hydrogen stream from step (b) and the separate nitrogen stream from step (c) into an ammonia synthesis loop and converting the nitrogen and hydrogen stream to ammonia.
