What is the Green Ammonia?

Green ammonia is a sustainable form of ammonia produced by combining nitrogen extracted from the air with green hydrogen generated through water electrolysis powered entirely by renewable energy sources such as solar, wind, or hydropower. Unlike conventional ammonia, which relies on fossil fuels and emits significant carbon dioxide during production, green ammonia is manufactured with little to no greenhouse gas emissions. It serves as an environmentally friendly energy carrier, hydrogen storage medium, and industrial feedstock for applications including fertilizers, power generation, marine fuel, transportation, refrigeration, and chemical manufacturing, supporting global decarbonization and clean energy transition efforts.

Use Cases

• Power Generation: Green ammonia is increasingly used as a low-carbon fuel for co-firing and dedicated combustion in thermal power plants to reduce greenhouse gas emissions while utilizing existing power generation infrastructure. Japanese utilities are investing in ammonia-compatible turbines and combustion technologies to support the country's decarbonization roadmap and improve energy security through diversified fuel sources.
• Transportation: The transportation sector is adopting green ammonia as a clean marine fuel and hydrogen carrier for long-distance energy transport. Its high energy density and established storage infrastructure make it suitable for shipping, heavy-duty vehicles, and future hydrogen distribution networks, supporting Japan's efforts to develop sustainable mobility solutions.
• Fertilizer Production: Green ammonia serves as a sustainable alternative to conventionally produced ammonia in fertilizer manufacturing. Its adoption enables fertilizer producers to significantly reduce carbon emissions while maintaining production efficiency. Increasing demand for environmentally responsible agricultural inputs is encouraging investments in low-carbon ammonia production technologies.
• Refrigeration and Industrial Applications: Green ammonia is widely utilized as a natural refrigerant in industrial cooling systems and as a feedstock in chemical manufacturing. Industries are increasingly replacing conventionally produced ammonia with green alternatives to meet sustainability targets, comply with environmental regulations, and reduce lifecycle carbon emissions across manufacturing operations.
