What Will Drive Brazil’s Green Ammonia?

Brazil appears to have nearly everything required to become a major green ammonia producer: abundant renewable resources, a large agricultural economy, established ports and substantial domestic demand for nitrogen-based products. Yet these advantages do not point toward a single market. Brazil’s green ammonia development is being pulled in three directions—exports, fertilizer import substitution and broader green industrialization.

Understanding which force matters most requires separating announced project capacity from the demand most likely to support the first operating plants.

Brazil Starts with a Renewable Advantage

Brazil’s strongest advantage is its electricity system. According to the Brazilian Energy Balance 2026, renewable sources supplied 86.8% of the country’s electricity in 2025. Hydropower represented 51.2%, followed by wind at 14.9%, solar at 11.4% and biomass at 8.4%.

This combination is important for green ammonia. Hydropower can provide a relatively stable foundation, while wind and solar offer expanding supplies of low-carbon electricity. In the northeast, strong wind and solar resources support large coastal projects. In the south and southeast, hydropower, biomass and regional renewable generation can serve industrial and agricultural users.

A renewable electricity system does not automatically guarantee cheap hydrogen. Grid access, transmission constraints, PPA structures and hourly electricity availability still affect production costs. Nevertheless, Brazil begins with a stronger resource base than most potential green ammonia producers.

Exports Define the Headline Market

The largest announced projects are concentrated around ports such as Pecém in Ceará. These developments are designed to convert renewable electricity into hydrogen derivatives that can be stored and shipped to international markets.

Casa dos Ventos, Comerc and the TransHydrogen Alliance, for example, announced a Pecém project with up to 2.4 GW of electrolysis and potential production of approximately 2.2 million tonnes of green ammonia annually. Its first phase was proposed primarily for export to Europe through Rotterdam under a memorandum of understanding. The developers’ announcement illustrates why exports dominate Brazil’s announced capacity.

International demand can justify the scale required for dedicated renewable generation, transmission, storage tanks and port infrastructure. However, many export-oriented projects remain at the MoU, environmental licensing or engineering stage. Their size demonstrates ambition, but not necessarily which market will reach operation first.

Agriculture Provides the Clearest Demand

Brazil’s agricultural sector offers a more immediate domestic rationale. The country consumes around 40 million tonnes of fertilizers annually, while an EPE analysis estimated external dependence of 96.4% for nitrogen fertilizers and found that domestic production supplied only about 5% of internal nitrogen demand. This exposes farmers to international prices, exchange rates and logistics disruptions. EPE’s nitrogen fertilizer study identifies reducing this dependence as a strategic national concern.

The National Fertilizer Plan therefore aims to attract at least two additional nitrogen fertilizer producers and US$10 billion in private investment by 2030. Its official targets create a policy connection between hydrogen development and agricultural security.

Projects such as Atlas Agro’s proposed Uberaba facility reflect this logic. The plant is designed to use renewable electricity to produce green hydrogen, ammonia and ammonium nitrate for Brazilian farmers rather than for export. Atlas Agro states that the integrated operation would consume about 2.5 TWh of renewable electricity annually.

Agriculture is also compatible with smaller regional plants. Producing ammonia, ammonia solution or downstream fertilizers closer to inland users could reduce transport requirements and allow capacity to grow alongside confirmed local demand.

Green Industrialization Creates Wider Value

Green ammonia could also become part of a broader industrial strategy. Brazil has mining, steel, refining, chemical, biofuel and port industries that will need lower-carbon feedstocks and fuels. Ammonia can supply nitrogen for mining explosives, replace fossil-based hydrogen in industrial processes, support low-carbon fertilizers and serve as an input for synthetic fuels.

Brazil’s hydrogen law explicitly supports both domestic use and exports, while encouraging hydrogen derivatives that add value to national production. It also calls for the development of domestic equipment and supply chains. Law 14,948/2024 therefore frames hydrogen as an industrial policy instrument, not simply an export commodity.

This opportunity is broader than green ammonia alone. Brazil’s legal framework is technology-neutral and defines low-carbon hydrogen by lifecycle emissions, meaning renewable electrolysis must compete with biomass, biomethane and other qualifying pathways.

Three Drivers, Three Time Horizons

So what will drive Brazil’s green ammonia market?

Exports currently dominate announced capacity and will continue shaping large port-based projects. Agriculture provides the clearest near-term domestic demand because fertilizer imports create an existing economic and strategic problem. Green industrialization offers the greatest long-term value by connecting renewable energy with higher-value products, industrial jobs and lower-carbon supply chains.

Brazil’s green ammonia future is therefore unlikely to follow one route. Large export projects may establish global scale, while fertilizer plants—particularly regional and modular facilities—could provide the first repeatable domestic business models. In the longer term, the strongest market will emerge where all three drivers reinforce one another: renewable resources supporting local industry while also creating competitive products for international markets.
