Green ammonia manufacturing requires equipment for water electrolysis, air separation, and ammonia synthesis. Key components include alkaline or other types of electrolyzers to produce green hydrogen from water and renewable electricity, a nitrogen generator (often using Pressure-Swing-Adsorption ) to separate nitrogen from the air, and a synthesis converter that uses a process like Haber-Bosch to combine hydrogen and nitrogen into ammonia. Other equipment includes water purifiers, compressors, and storage tanks .
