Green ammonia provides a sustainable alternative, offering the same benefits for crop production without the associated carbon emissions.
• Energy Storage and Transport: Green ammonia has the potential to revolutionize energy storage and transport. Unlike hydrogen, which requires expensive and complex infrastructure for storage and distribution, ammonia can be easily liquefied and stored at relatively low pressures. This makes it an ideal candidate for storing excess renewable energy and transporting it over long distances.
• Fuel for Shipping and Heavy Industry: The maritime and heavy industrial sectors are some of the most challenging to decarbonize due to their reliance on high-density energy sources. Green ammonia can serve as a carbon-neutral fuel for ships, replacing bunker fuel and reducing the sector's carbon footprint. Additionally, it can be used in industries such as steel and cement production, where electrification is difficult and alternative fuels are needed.

Production of Green Ammonia

Green ammonia production relies on renewable energy to power the electrolysis of water, which produces hydrogen. This hydrogen is then combined with nitrogen extracted from the air to produce ammonia. The key difference between green ammonia and traditional ammonia lies in the energy source used for hydrogen production—green ammonia uses renewable energy, while traditional ammonia relies on fossil fuels.

• Electrolysis: The first step in producing green ammonia is electrolysis, where water is split into hydrogen and oxygen using an electric current. When this electricity is sourced from renewable energy, the hydrogen produced is considered green. Electrolysis is a well-established technology, and advancements in this field are driving down costs and increasing efficiency.
• Ammonia Synthesis: Once green hydrogen is produced, it is combined with nitrogen from the air to form ammonia (NH3) through the Haber-Bosch process. Although the process itself remains the same, the use of green hydrogen ensures that the entire production chain is carbon-neutral.
• Renewable Energy Sources: The scalability of green ammonia production depends largely on the availability and cost of renewable energy. Wind, solar, and hydropower are the primary sources of energy for green ammonia production. As the cost of renewable energy continues to decline, green ammonia is becoming more economically viable.
