Green Ammonia: A Practical Path to Cleaner Energy

Green Ammonia: A Practical Path to Cleaner Energy

Green ammonia is gaining traction. It offers a way to store and transport hydrogen without the risks and inefficiencies of compressed gas. It supports decarbonization in shipping, power generation, and fertilizer production.

Here’s what you need to know.

What is Green Ammonia?

• Green ammonia is produced by combining nitrogen with hydrogen obtained through water electrolysis powered by renewable energy sources (such as wind or solar).
• Conventional ammonia production typically uses hydrogen derived from natural gas or other fossil fuels, which releases significant amounts of CO₂ during the process.
• Green ammonia eliminates these CO₂ emissions at the production stage, making it a sustainable alternative for industries like agriculture and shipping that rely heavily on ammonia.

Why it matters?

Ammonia is easier to store and transport than hydrogen. It’s already traded globally. Infrastructure exists. That makes green ammonia a strong candidate for scaling clean energy.

Process and Benefits

Since ammonia is a liquid at -33 °C and hydrogen needs -253°C or high-pressure tanks, ammonia is considered much less volatile and easier to handle. Existing pipelines, ships, and terminals can be adapted.

Green Ammonia Applications

Green ammonia supports sectors that are hard to electrify:

• Shipping: Ammonia-fueled engines are in development
• Power: Ammonia can be co-fired in coal plants to reduce emissions
• Fertilizer: Green ammonia replaces fossil-based ammonia in agriculture

What are the Challenges of Green Ammonia?

Green ammonia presents several technical and economic challenges that slow adoption. Its toxicity is a serious concern. Exposure can cause respiratory damage and chemical burns, so handling and transport require strict safety protocols and specialized equipment. Cost is another major barrier. Producing hydrogen through electrolysis powered by renewables is still expensive, making green ammonia less competitive than fossil-based alternatives. 

Converting ammonia back into hydrogen consumes energy and adds complexity, which limits its use in some applications. Scaling production is difficult. Most current projects are small or experimental, and moving to commercial scale demands significant investment, regulatory clarity, and long-term demand signals. Infrastructure gaps add to the problem. Existing facilities need upgrades to safely store, move, and use ammonia at scale.

Market Outlook for Green Ammonia

Despite the hurdles, momentum is building. IRENA estimates green ammonia could supply 45 percent of global ammonia demand by 2050, which translates to over 200 million tonnes annually. More than 100 projects are in development, with Australia, Chile, and Saudi Arabia leading in capacity. 

Governments are also backing the shift. The EU includes ammonia in its hydrogen strategy, Japan is testing ammonia co-firing in coal plants, and both India and the US offer tax credits and subsidies to support production. 

Demand from the shipping sector is also rising. The International Maritime Organization’s net-zero target for 2050 is pushing operators to explore ammonia as a marine fuel. Investment is shifting as well. Major energy companies and fertilizer producers are entering the market, forming joint ventures and public-private partnerships to accelerate deployment and reduce costs.

How Celeros Flow Technology Supports This

• Our pumps and valves handle ammonia safely and reliably
