The invention relates to a method for producing ammonia (1), wherein a carbon-containing energy carrier flow (2) and an oxygen flow (3) from an oxygen-producing assembly (4) are fed to a synthesis gas reactor assembly (5) for obtaining a synthesis gas flow (6) with hydrogen and carbon oxides, wherein the synthesis gas flow (6) is fed to an adsorption device (7) for separating the synthesis gas flow (6) into a hydrogen flow (8), which comprises hydrogen, and a purge flow (9), and wherein the hydrogen flow (8) and a nitrogen flow (10) are fed to an ammonia reactor assembly (11) and converted into ammonia (1) there. The method is characterized in that the purge flow (9) is fed to a recovery device (12), which obtains a hydrogen-containing recovery flow (13) from the purge flow (9) and discharges a waste gas flow (14) therefrom, and that the hydrogen of the recovery flow (13) is at least partly fed to the ammonia reactor assembly (11) for conversion into ammonia (1). The invention also relates to a corresponding system for the production of ammonia (1).
