How to make green ammonia ?
The production of green ammonia is based on renewable energy + water + air, and the core process is as follows:
- Water electrolysis for hydrogen: Renewable electricity—such as solar or wind power—drives electrolyzers to split water and produce green hydrogen (H₂).
- Air separation for nitrogen: Nitrogen (N₂) is extracted from the air.
- Green ammonia synthesis: Green hydrogen and nitrogen undergo the Haber–Bosch reaction under catalyst, high-temperature, and high-pressure conditions to synthesize green ammonia (NH₃).
Key feature: The production process does not rely on fossil energy and achieves zero carbon emissions.

How does green ammonia benefit society ?
-
Accelerating global decarbonization: By replacing conventional ammonia and fossil fuels, green ammonia can significantly reduce CO₂ emissions and support the achievement of carbon-neutrality goals.
Enhancing food security: As a key raw material for fertilizer production, green ammonia reduces agriculture's dependence on natural gas and provides a more stable foundation for the global food supply chain.
Easing energy shortages: Green ammonia can serve as an energy carrier for storage and transportation, becoming an important "green fuel" for international energy trade.
Promoting economic growth and employment: The green ammonia value chain (renewable energy, electrolyzers, ammonia synthesis equipment, storage and transportation systems, etc.) stimulates job creation, drives local economic development, and supports social stability and sustainable growth.
How is green ammonia used as fuel ?
Green ammonia can be utilized directly for power generation. It can be combusted in gas turbines or internal combustion engines, co-fired with conventional fuels, or cracked to produce hydrogen for fuel cells. As a carbon-free energy carrier, it enables stable electricity generation, long-duration energy storage, and reliable power supply for remote or off-grid regions.

What is the difference between ammonia and green ammonia?
Conventional ammonia (gray ammonia):
- Hydrogen is produced from fossil fuels such as natural gas or coal.
- The production process generates large amounts of CO₂ and is a major source of industrial carbon emissions.
Green ammonia:
- Hydrogen comes from water electrolysis powered by renewable energy such as wind or solar power.
- The production process results in virtually no carbon emissions and is recognized globally as a low-carbon nitrogen product.
Essential difference: They share the same uses, but differ fundamentally in carbon-emission sources and environmental impact—the environmental value is completely different.
Is there a market for green ammonia?
According to Mordor Intelligence, global green ammonia production is expected to reach 270,000 tons in 2025, and grow to 5.41 million tons by 2030, with a compound annual growth rate (CAGR) as high as 97%.
What is green ammonia fertilizer?
The chemical composition of green ammonia is the same as that of conventional ammonia-based fertilizers (such as anhydrous ammonia, ammonium nitrate, and urea, all of which are made from ammonia). However, its production process uses renewable energy and green hydrogen, which significantly reduces CO₂ emissions during manufacturing. In other words, "green ammonia fertilizers" refer to ammonia-based fertilizers produced with zero-carbon ammonia.
Significance: They can help agriculture reduce emissions from the upstream supply side. (However, issues such as nitrogen loss and N₂O emissions during field application still require proper management.)
Is green ammonia toxic?
Chemical toxicity is the same as conventional ammonia:
Green ammonia is still chemically NH₃. It is irritating and strongly corrosive/irritating to the respiratory tract, eyes, and skin. Inhaling high concentrations can cause severe respiratory damage or even death. It is also toxic to water bodies (harmful to aquatic organisms). Therefore, safety procedures for handling, transporting, and storing green ammonia are exactly the same as for conventional ammonia and are extremely important.
Green ammonia ≠ harmless ammonia — it is simply ammonia produced with zero-carbon processes.
Green ammonia vs Blue ammonia price
Green Ammonia: Costs are mainly determined by renewable electricity prices, electrolyzer efficiency, and plant scale.
Blue Ammonia: Produced via conventional fossil-fuel routes combined with carbon capture (CCS). Its cost depends on natural gas prices and the carbon-capture rate.
For example:
Based on current quotations from KAPSOM, green ammonia is priced at approximately USD 600–800 per ton.
Northwest Europe prices rise 4% to $676/mt; Asia edges lower
Blue ammonia FOB US Gulf reported at a minimum of $400–$600/mt
Japan–Korea Ammonia Price assessed at $435–$475/mt CFR
(subject to fluctuations in natural gas and CCS costs)
