Topsoe to supply ammonia technology for First Ammonia’s Texas green ammonia project

In August 2026, Topsoe signed an agreement with First Ammonia to supply its dynamic ammonia synthesis technology for a green ammonia production facility in Victoria, Texas. The project represents another step toward establishing commercial-scale green ammonia production in the United States. The planned facility is set to produce green ammonia using green hydrogen generated through electrolysis powered by renewable electricity.

The ammonia is expected to serve both US and international markets. Financial close for the project is expected later in 2026, while commercial operations are targeted to begin in 2029. Joel H. Moser, CEO of First Ammonia, said the company is continuing its partnership with Topsoe to support the development of a green ammonia industry in the US and globally.

Under the agreement, Topsoe will also provide its dynamic ammonia synthesis technology, which is designed specifically to address the operational requirements of green ammonia plants. Unlike conventional ammonia production systems, green ammonia facilities can experience fluctuations in renewable power generation. Therefore, production flexibility is a critical aspect for maintaining efficient and reliable operations.

Topsoe’s technology allows the ammonia synthesis loop to ramp production from 10% to 100% within 30 minutes. Similarly, operators can reduce production at a comparable rate. This flexibility enables the system to respond quickly to changes in renewable electricity availability while maintaining safe and stable operations.

Impact on the Chemical Market

The project will use green hydrogen that is produced through electrolysis powered by renewable electricity. The facility is being developed to supply green ammonia to both US and international markets. The technology can ramp ammonia production from 10 percent to 100 percent, or reduce it at a similar rate, within 30 minutes, enabling the synthesis loop to operate safely, reliably and efficiently despite changes in available power.

The Victoria project is part of First Ammonia’s broader strategy to develop modular, commercial-scale green ammonia plants powered by renewable energy. The company is targeting project sites worldwide with access to low-cost renewable energy and/or government incentives. First Ammonia aims to develop, own and operate production facilities across five continents, with engineering and project development operations in Houston and Copenhagen. Green ammonia is also being increasingly positioned as a potential decarbonization option for agriculture, chemicals, power generation and energy storage, as well as transportation and renewable-energy-based fuels.

Impact on the Green Ammonia Market

The global green ammonia market size is calculated at USD 885.83 billion in 2025 and is predicted to increase from USD 1,473.31 billion in 2026 to approximately USD 86,268.30 billion by 2034, growing at a CAGR of 66.32% from 2025 to 2035.

According to Precedence Research, the market at the global level is gaining rapid expansion as industries across the globe adopt carbon-neutral technologies and renewable energy in other applications. Green ammonia, produced by electrolyzing water with renewable energy sources such as wind and solar, is now being identified as a key solution for reducing carbon emissions in other applications. Increasing applications in fertilizers, marine fuels, and energy storage are driving demand and fast-tracking production efficiency initiatives by governments; policy incentives and technology are increasing social and global productivity, making GNH3 an important part of the global transition to renewable energy generation & storage.

Supportive policies and financial support for green hydrogen and ammonia production are encouraging investment, and therefore, accelerating technology adoption and infrastructure development in countries around the world. Innovations in electrolysis or the coupling of renewable energy supply to production are lowering amortized costs and eventually making green ammonia more cost-competitive with conventional ammonia. Green ammonia's potential as a hydrogen carrier and energy storage medium is supporting its wave of interest in energy transition plans and policies, particularly in countries and regions likely to be exporting.

Impact on the Green Hydrogen Market

The global green hydrogen market size is calculated at USD 12.31 billion in 2025 and is predicted to increase from USD 17.28 billion in 2026 to approximately USD 231.32 billion by 2035, expanding at a CAGR of 34.09% from 2026 to 2035.

According to Precedence Research, market growth is driven by global government initiatives to reduce carbon emissions and advancements in green hydrogen production technology. The green hydrogen market is a rapidly expanding industry focused on producing hydrogen fuel with zero emissions. This is achieved through the electrolysis of water using renewable energy sources like solar and wind. Green hydrogen is a clean energy source that emits only water vapor, leaving no residues in the air, unlike coal and oil.

Another major factor that is contributing to the growth of the green hydrogen market is the decreasing cost of production. As the costs of renewable energy continue to fall, the expenses associated with green hydrogen production through electrolysis are also projected to decline. Furthermore, growing economies of scale in green hydrogen production can help drive down costs, making it more competitive with traditional fossil fuels. Increasing government initiatives and subsidies aimed at achieving net-zero emissions, along with growing investments in renewable hydrogen production infrastructure, are also helping to accelerate market expansion. Active research and development, coupled with technological advancements, are fostering innovative and efficient solutions in green hydrogen production, driving industry trends.
