The invention relates to a method and plant for producing hydrogen comprising an electrochlorination unit (10) and a water electrolysis unit (11). In the electrochlorination unit (10), seawater (12) or brine is electrolyzed to produce a liquid hypochlorite stream and an oxygen-polluted hydrogen gas stream. The hydrogen gas is separated from the liquid phase in a degasser vessel (18). High-purity hydrogen produced in the water electrolysis unit (11) from demineralized water (22) is divided into two portions, one portion (37) being mixed with the oxygen-polluted hydrogen in the degasser vessel (18) to form a non-flammable mixed gas, and the other portion (38) being supplied to an ejector (50) for compressing and further concentrating the mixed hydrogen. Optionally, residual oxygen is removed in a DE-OXO unit (54).
