Brazil’s Small-Scale Green Ammonia Future

Brazil’s green ammonia ambitions are usually measured in gigawatts and millions of tonnes. Large projects at Pecém and other ports may eventually position the country as an international supplier. They are not, however, the only way for a green ammonia market to begin.

Smaller plants can address a different problem: supplying ammonia and nitrogen products closer to Brazilian farms and industrial users. Rather than waiting for export infrastructure and global offtake to mature, distributed projects can establish local demand, operating experience and regulatory confidence.

Small Plants Deserve a Place

A small green ammonia plant is unlikely to match the production cost of a fully utilized world-scale fossil ammonia complex. Its value must therefore be measured differently.

A regional plant can reduce the distance between production and consumption, avoid some port and inland distribution requirements and produce a form of nitrogen better suited to a specific user. It can also begin with a confirmed local demand base and expand in modules, limiting the capital committed before the market is proven.

This model is particularly relevant in Brazil because renewable resources and industrial demand are geographically dispersed. The best location for exporting ammonia from a port is not necessarily the best location for supplying an agricultural cooperative, mine or chemical plant hundreds of kilometres inland.

Agriculture Is the Natural Starting Point

Agriculture provides the strongest case for early deployment. EPE estimates that Brazil consumes around 40 million tonnes of fertilizers annually and depends on imports for approximately 96.4% of its nitrogen fertilizer requirements. Domestic production has supplied only about 5% of nitrogen demand. EPE’s fertilizer analysis also identifies freight as one of the variables affecting the economics of imported ammonia and urea.

This creates opportunities beyond simply producing commodity anhydrous ammonia. A regional plant could supply ammonia solution, liquid nitrogen fertilizer or feedstock for another locally manufactured product. Production can be aligned with the actual demand of nearby farms, distributors or cooperatives.

Rio Grande do Sul is beginning to test this model. BeGreen’s Passo Fundo project is designed for approximately 2,000 tonnes of green ammonia per year, while the Tio Hugo project has a licensed upper capacity of about 4,360 tonnes per year. Both have obtained Preliminary Environmental Licences.

As of July 2026, the developer was still completing the Installation Licence process, with construction not yet confirmed. The latest reported status means these are not operating references, but they are the clearest evidence that Brazil’s small-scale opportunity has moved beyond general discussion.

A Local Partnership Model Is Emerging

The Passo Fundo project also suggests how distributed green ammonia may be developed.

Its structure brings together BeGreen, the University of Passo Fundo, the municipal government and Japanese engineering and investment group OC Global. The city’s support includes provisions related to water infrastructure and access roads, while the university provides land, research cooperation and workforce development. OC Global has invested in the local project company. The company’s disclosure presents the plant as an on-site production and sales model rather than an export facility.

This combination addresses several early-stage barriers at once: financing, local acceptance, technical capacity, infrastructure and demand development. For first projects, such partnerships may be as important as electrolyser efficiency or ammonia synthesis technology.

Opportunities Beyond Fertilizer

Agriculture is the most visible starting point, but not the limit.

Mining regions could eventually use locally produced ammonia as feedstock for ammonium nitrate explosives. Refineries and chemical plants could replace part of their conventional hydrogen or ammonia consumption without immediately converting an entire facility. Ports could begin with ammonia fuel demonstrations for harbour vessels, while renewable energy developers could use small plants to test flexible operation and Power-to-X integration.

These applications are less mature than agricultural projects, so they should initially be linked to a specific user rather than built for an undefined future market. Industrial clusters such as the Port of Açu are already assessing green ammonia, e-methanol, e-SAF, fertilizers, chemicals and low-carbon steel within a shared infrastructure platform. Açu’s development strategy illustrates how ammonia may ultimately connect several value chains.

What Makes a Small Plant Competitive

Small-scale green ammonia will not succeed simply because renewable electricity is available. A viable project needs several conditions:

• a long-term local offtaker
• predictable renewable power rather than occasional curtailed electricity
• a product specification matched to the end user
• manageable water, storage and transport requirements
• modular expansion instead of oversized initial capacity
• Brazilian engineering, safety and environmental compliance
• local operating and maintenance capability

The strongest projects will compare the delivered cost and service value of the final nitrogen product—not only the plant-gate cost of ammonia.

A South American Pioneer

Brazil has the renewable electricity, agricultural demand, industrial base and policy interest required to lead a distributed green ammonia market in South America. The remaining step is to turn the first licensed plants into reliable operating references.

KAPSOM sees a practical role for standardized modular systems from 100 to 5,000 tonnes per year in this transition. Demonstration units can support research and industrial trials, while 2,000–5,000-tonne plants can serve defined agricultural or industrial demand.

Brazil’s green ammonia future may still include million-tonne export facilities. But its most influential first projects could be much smaller—producing locally, serving real users and creating a model that can be repeated across the country and eventually across South America.
