Ammonia has been known for more than 200 years. The production of significant quantities of ammonia using the cyanamide process did not occur until the early 20th century. Ammonia production is a vital industrial process that involves the synthesis of ammonia (NH₃) from its elemental components: nitrogen (N₂) and hydrogen (H₂). This process is primarily conducted using the Haber-Bosch process, named after its inventors Fritz Haber and Carl Bosch. 

In ammonia production, hydrogen serves as a crucial feedstock. An alkaline hydrogen electrolyzer is utilized in ammonia production for its ability to generate hydrogen efficiently through the electrolysis of water. This process involves splitting water molecules into hydrogen and oxygen using an alkaline electrolyte (typically potassium hydroxide) and electricity. This hydrogen can then be purified and used directly to synthesize ammonia.

Electrolyzers are favored in ammonia production due to their efficiency, reliability, and relative simplicity compared to other electrolysis technologies. They operate at lower temperatures and do not require expensive materials, making them cost-effective for large-scale hydrogen production in ammonia synthesis.
