Green Ammonia: An Overview

What is Green Ammonia?
Green ammonia is ammonia (NH₃) that is produced using renewable energy sources rather than fossil fuels. Traditional ammonia production relies heavily on natural gas through the Haber-Bosch process, which emits significant amounts of CO₂. In contrast, green ammonia is synthesized using hydrogen derived from water electrolysis powered by renewable energy (like wind, solar, or hydro) and nitrogen from the air. This makes the process virtually carbon-free.

Why is Green Ammonia Important?
Green ammonia is gaining attention as a potential key player in the global transition to sustainable energy and agriculture. Here’s why:

• Decarbonization: It offers a pathway to reduce emissions in agriculture (as a fertilizer), industrial processes, and heavy transport sectors.
• Energy Storage & Transport: Ammonia can store hydrogen energy in a stable, dense form, making it easier to transport and use as a fuel.
• Maritime Fuel: It is being explored as a low-carbon fuel for ships, offering a cleaner alternative to conventional marine fuels.

Production Process

1. Electrolysis: Water is split into hydrogen and oxygen using electricity from renewable sources.
2. Air Separation: Nitrogen is extracted from the air.
3. Synthesis: Hydrogen and nitrogen are combined using a modified Haber-Bosch process under high pressure and temperature to form ammonia.
