Brazil is emerging as a promising destination for green hydrogen development, supported by abundant renewable electricity, expanding industrial demand, and growing investment in low-carbon energy infrastructure. The country's combination of hydropower, solar, and wind resources provides a strong foundation for producing hydrogen through electrolysis while supporting applications across fertilizers, ammonia, refining, steel, chemicals, mobility, and energy exports.

According to MarkNtel Advisors, the Brazil green hydrogen industry was valued at USD 145 million in 2025 and is projected to reach USD 184 million in 2026 and USD 1.615 billion by 2032, registering a CAGR of 43.3% during 2026–2032. The Brazil green hydrogen industry is projected to reach USD 1.615 billion by 2032, with alkaline electrolysis accounting for 58% of the industry in 2026 and fertilizers & ammonia representing nearly 46% of demand.

Renewable Electricity Creates a Strong Foundation

Green hydrogen production depends on renewable electricity to power electrolyzers that split water into hydrogen and oxygen. Brazil has a significant advantage because its electricity system already has a high share of renewable generation. The MarkNtel Advisors assessment notes that renewable sources represented approximately 80% of Brazil's electricity generation in 2024.

This renewable-energy base can support hydrogen projects seeking low-carbon electricity while reducing dependence on fossil-based power. Brazil's large-scale hydroelectric assets, combined with rapidly expanding solar and wind capacity, provide developers with multiple pathways for sourcing renewable electricity.

The International Energy Agency highlights Brazil's extensive renewable-energy resources and their importance to the country's evolving energy system. IEA's Brazil energy profile provides broader context on the country's electricity mix and renewable-energy development.

Government Policy Strengthens Hydrogen Development

Brazil has established a dedicated policy framework for low-carbon hydrogen. Law No. 14,948/2024 created the legal framework for low-emission hydrogen, established the National Low-Carbon Hydrogen Policy, and introduced incentives for developing the industry.

The framework also defines renewable hydrogen and establishes regulatory responsibilities for production activities. Brazil's government has subsequently continued building institutional mechanisms to support hydrogen development and industrial decarbonization.

The Brazilian Ministry of Mines and Energy's low-carbon hydrogen framework identifies hydrogen as an important element of energy transition and industrial decarbonization, particularly for sectors where direct electrification can be challenging.

Alkaline Electrolysis Leads Technology Deployment

Alkaline electrolysis accounted for approximately 58% of Brazil's green hydrogen industry in 2026, according to MarkNtel Advisors. Its established commercial maturity and scalability make it an important technology for the country's early industrial-scale projects.

Brazil's first industrial-scale green hydrogen initiatives are helping establish practical experience with electrolyzer operation, renewable-power integration, hydrogen processing, and downstream applications. As additional projects advance, other technologies such as PEM, SOEC, and AEM electrolysis could gain greater relevance depending on project requirements.

Technology selection will increasingly depend on factors including electricity availability, operating flexibility, system efficiency, capital costs, and project scale.

Fertilizers and Ammonia Create Immediate Demand

Fertilizers and ammonia represented approximately 46% of Brazil's green hydrogen industry in 2026, making the segment the leading end-use category. This reflects the fundamental role of hydrogen in ammonia production and Brazil's large agricultural sector.

Domestic low-carbon ammonia production could also help address the country's substantial dependence on imported fertilizers. Green hydrogen can replace conventional hydrogen feedstocks in ammonia manufacturing, providing a potential pathway for reducing the carbon intensity of fertilizer production.

The Brazilian Ministry of Agriculture and Livestock provides extensive information on the country's fertilizer supply and agricultural input requirements. Brazil's Ministry of Agriculture provides official context for the strategic importance of fertilizer availability to the country's agricultural economy.

Industrial Decarbonization Expands Applications

Beyond fertilizers, green hydrogen can support decarbonization in industries where direct electrification is difficult. Refineries can use low-carbon hydrogen for hydrotreatment and other processes, while steelmakers can potentially use hydrogen-based reduction technologies to reduce dependence on carbon-intensive production routes.

Chemicals, heavy industry, mobility, and power generation represent additional application areas. The Brazilian government has identified low-carbon hydrogen as relevant to industrial sectors including fertilizers, refineries, steelmaking, metallurgy, cement, glass, and mining.

The legal framework also provides a foundation for developing domestic hydrogen production while supporting broader industrial transformation.

Gigawatt-Scale Projects Are Emerging

Brazil is moving from pilot initiatives toward larger hydrogen developments. According to MarkNtel Advisors, hydrogen-related projects account for 27.9 GW of grid-connection requests submitted to the National Interconnected System through 2038, indicating a substantial project pipeline.

The Pecém Industrial and Port Complex in Ceará is becoming an important hydrogen hub, combining renewable power, hydrogen production, industrial users, and export infrastructure. The development of integrated hubs can reduce logistical barriers by locating hydrogen production close to industrial consumers and ports.

The World Bank has also supported Ceará's green hydrogen strategy, highlighting the importance of infrastructure development in establishing a competitive hydrogen ecosystem.

Water Availability Requires Careful Planning

Electrolysis requires purified water, creating an important infrastructure consideration for large-scale projects. This is particularly relevant for hydrogen hubs located in coastal areas where freshwater resources may face competing agricultural, municipal, and industrial demands.

Desalination can provide an alternative source of process water for coastal projects. Integrating desalination with renewable electricity and electrolysis could allow developers to reduce pressure on freshwater resources while maintaining reliable hydrogen production.

The International Renewable Energy Agency has examined water requirements associated with hydrogen production and the infrastructure considerations involved in developing renewable hydrogen systems. IRENA's green hydrogen resources provide additional context on production technologies and related infrastructure.

Export Potential Adds Long-Term Opportunity

Brazil's geographic position and access to Atlantic shipping routes create opportunities to supply hydrogen-derived products to international markets. Green ammonia can be particularly relevant because it is easier to transport using established maritime infrastructure than pure hydrogen.

Export-oriented hubs could therefore connect Brazil's renewable resources with international demand for lower-carbon fuels, chemicals, fertilizers, and industrial feedstocks.

Outlook for Brazil's Green Hydrogen Industry

Brazil's green hydrogen industry is developing around renewable electricity, industrial decarbonization, fertilizer production, large-scale projects, and export opportunities. Alkaline electrolysis currently leads deployment, while fertilizers and ammonia provide an established source of demand.

Future expansion will depend on project financing, renewable-power costs, electrolyzer technology, water availability, infrastructure, certification, and international offtake agreements. With strong renewable resources and an increasingly defined policy framework, Brazil is positioned to become an important participant in the global low-carbon hydrogen economy.
