Green ammonia market to hit $6.5 billion by 2031

Allied Market Research projects the global green ammonia market will surge from $0.02 billion in 2021 to $6.5 billion by 2031, driven by decarbonization rules, renewable hydrogen investment and new uses in power, transport and industry. Europe led the market in 2021, while Asia-Pacific is forecast to grow the fastest.

Why it matters: - Green ammonia is moving from a niche concept to a scaled clean-energy market. - The forecast points to a major commercial opportunity for hydrogen, shipping, power generation and industrial users. - The market’s growth rate signals how quickly low-carbon fuels are being pulled into energy transition plans.

What happened: - Allied Market Research said the global green ammonia market was valued at $0.02 billion in 2021. - The market is projected to reach $6.5 billion by 2031. - The forecast implies an 80.1% CAGR from 2022 to 2031. - Europe led the market in 2021, contributing nearly two-fifths of total revenue. - The report was published July 6, 2026. - Download the sample pages of the research overview.

The details: - Stronger environmental rules and rising concerns about carbon emissions are key growth drivers. - Government support for decarbonization is also fueling demand. - Green ammonia is gaining use in power generation, transportation and industrial processes. - Rising investment in renewable hydrogen production is expanding the addressable market. - The report identifies maritime fuel as a major emerging opportunity. - Shipping companies are seeking low-carbon fuels, and green ammonia is positioned as a zero-carbon alternative. - High capital costs remain a major barrier. - Infrastructure buildout adds to the cost burden. - Technology deployment and scalability remain unresolved challenges.

Between the lines: - The market outlook reflects a shift from policy ambition to early industrialization. - Europe’s lead suggests the strongest early demand is still coming from regions with the most aggressive climate policy. - The fastest growth in Asia-Pacific points to where future project development may accelerate as hydrogen infrastructure expands.

What’s next: - The Alkaline Water Electrolysis segment is expected to keep the largest share through 2031. - That technology held more than three-fifths of the global market in 2021. - Solid Oxide Electrolysis is projected to post the fastest growth, with an 81.3% CAGR. - The report also covers Proton Exchange Membrane technology. - Power generation remained the leading application in 2021, with nearly two-fifths of the market. - The “Others” application segment is expected to grow the fastest, at an 81.2% CAGR. - Asia-Pacific is forecast to post the fastest regional CAGR at 81.1%. - Growth in the region is tied to renewable energy projects, hydrogen infrastructure and clean-fuel policy support. - The report also includes North America and LAMEA. - Major companies profiled include Siemens AG, NEL ASA, ThyssenKrupp, ITM Power, CF Industries Holdings, Ballard Power Systems, AMMPower, FuelPositive, Haldor Topsoe, Uniper, Hyport Duqm, Enapter, Starfire Energy, Engie, BASF SE, Yara International, Hiringa Energy and Queensland Nitrates. - These companies are pursuing partnerships, capacity expansions, product innovation and new projects.

The bottom line: - Green ammonia is still a small market today, but policy support and clean-fuel demand are setting up explosive growth over the next decade.
