Natural Gas as a Pillar of Brazil’s Energy Security: Insights from Gas Week 2026

A comprehensive panel discussion on the impact of Brazil's Capacity Reserve Auction (LRCAP) on the natural gas market, recorded on the second day of the Gas Week 2026, organized by Eixos, highlighted the pivotal role of natural gas in the nation's energy matrix. With 90 projects and 15 GW of gas thermal plants contracted, the panel brought together key players including Eneva, Petrobras, Origem Energia, Cocal, and ED, alongside regulators EPE and ANP, to debate critical issues such as tariffs, LNG, storage, biomethane, and the future steps for the post-auction gas market.

Brazil’s recent capacity reserve auction has solidified the role of natural gas as a critical pillar for the country’s energy security, with major industry players securing key contracts to provide dispatchable power to a grid increasingly reliant on intermittent renewable sources.

The auction, held in March and conducted by ANEEL, MME, and CCEE, successfully contracted 18.97 GW of capacity — primarily from gas-fired thermal plants. The projects represent R$ 64.5 billion in total investments with delivery dates ranging from 2026 to 2031. The auction achieved a 5.52% discount, resulting in estimated savings of R$ 33.64 billion.

The results were the focus of intense discussion at the Gas Week 2026 conference in Brasília, where executives and regulators analyzed the long-term impacts on the nation’s energy and gas markets.

Eneva and Petrobras Secure Dominance

Eneva, the largest private natural gas producer in Brazil, emerged as a protagonist in the auction. Despite legal challenges and scrutiny from the Federal Audit Court (TCU), Executive Director of Marketing, Sales and New Business at Eneva, Marcelo Lopes, expressed confidence in the process.

"The auction was not designed to favor specific agents, but to contract the energy security the system needs," Marcelo stated during a panel. He noted that national energy planners (EPE) and the grid operator (ONS) have signaled the need for dispatchable power since 2021.

State-run oil giant Petrobras also secured significant re-contracting for its existing thermal fleet. Leonardo Santos Ferreira, a Petrobras Gas and Energy Marketing Manager, highlighted that the new contracts provide the fixed revenue necessary for infrastructure investments, with a renewed focus on "operational flexibility." This allows plants to be dispatched up to twice a day to balance the grid.

Market Volatility and New Frontiers

The auction is expected to transform the Brazilian gas market by treating gas as a "flexibility fuel." Flávia Barros, director of Origem Energia, noted that the intermittent demand from thermal plants would likely increase short-term price volatility, creating both risks and opportunities for traders.

"The winners in the post-auction market will be those capable of coordinating infrastructure and operating in a regionally fragmented environment," Flávia said, highlighting Origem’s strategy of integrating upstream production with strategic gas storage.

In a first for Brazil’s capacity auctions, Cocal successfully negotiated thermal projects powered by biomethane, signaling a shift toward replacing fossil fuels with renewable gas in the industrial and power sectors.

Regulatory and Infrastructure Outlook

The National Petroleum Agency (ANP) estimates that the auction results could lead to the contracting of 49 million cubic meters of gas per day. Pietro Mendes, an ANP director, emphasized that this volume is crucial for maintaining the financial health of the gas transport system and could help lower transport tariffs in the long run.

Heloisa Borges, Director at the Energy Research Office (EPE), concluded that the Brazilian gas industry has reached a level of maturity capable of delivering diversified solutions, including LNG, domestic gas, and pipeline imports.

"We saw a robust industry capable of responding to the different needs of various actors," Borges said, pointing to the upcoming Integrated National Infrastructure Plan as the next step in supporting Brazil's growing gas production.

BNDES Approves R$384.9 Million to Boost Brazil’s Biomethane Infrastructure and Green Logistics

Brazil's National Bank for Economic and Social Development (BNDES) has approved two significant financing packages which total R$384.9 million ($74.5 million) for the development of biomethane infrastructure and the decarbonization of the logistics sector in Brazil. The projects will establish a green corridor system in São Paulo and create a new biomethane production facility in the state of Goiás.

The BNDES approved R$140 million for TransJordano a road transport company to implement a green corridor in São Paulo state. The project will use the funds to purchase 100 biomethane-powered trucks and build three biomethane fueling stations which will be located in Sumaré and Cubatão and Ribeirão Preto. The project financing will be funded through R$98 million from the Climate Fund (Fundo Clima) and R$42 million from the BNDES Machinery and Services line which together fund 92% of the total project costs. The biomethane stations will use Ultragaz as their fuel supplier while also permitting access to other transport companies.

Aloizio Mercadante, President of BNDES, declared that the project supports President Lula's energy transition policy because it provides sustainable cargo transport solutions to Brazil. "With this project, developed in São Paulo, we will see a reduction in the emission of 6.5 tons of equivalent CO2 in the first year of operation just with the biomethane-fueled fleet," Mercadante said.

João Bessa, President of TransJordano, showed how the company makes decarbonization its main priority. "This is an investment that goes beyond operations – it's a real commitment to the decarbonization of road transport and the future of the country," Bessa commented.

BNDES also approved R$244.9 million in funding to bp bioenergy for building a biomethane plant which will be located in Edéia, Goiás, next to the Usina Tropical mill. The financing package consists of R$193.4 million which comes from the Climate Fund and R$51.4 million which comes from Finem. The plant will generate 67,000 cubic meters of daily biomethane through biodigestion of vinasse which is produced during sugarcane ethanol production. The project has a total investment of R$275.8 million and is scheduled to finish development by 2027 while generating 300 employment opportunities through direct and indirect work.

Andres Guevara de la Vega, CEO of bp bioenergy, expressed enthusiasm for the project. "This project brings together technology, circularity, and strategic partnerships to transform an ethanol co-product into a new source of renewable energy," he noted. Ultragaz will distribute the biomethane which this unit generates.

TransJordano established its operations in 1998 and currently runs its business from Paulínia in São Paulo to provide sensitive cargo transport services which include fuels and chemical derivatives across the entire country. The company operates with more than 1,000 employees and maintains a fleet that exceeds 1,500 vehicles.

Ultragaz has been providing energy solutions to more than 11 million households and 57000 businesses since its establishment 88 years ago which now operates in 22 Brazilian states and the Federal District. The company operates as a subsidiary of Ultrapar, which stands as one of Brazil's most extensive business conglomerates.

bp bioenergy runs 11 operational facilities throughout five Brazilian regions while serving as a leading ethanol producer who creates substantial quantities of vinasse.

Brazil's Biomethane Boom: A Green Energy Revolution on the Horizon

Brazil is about to make major progress in its green energy transition because the biomethane industry will draw investments that reach R$348 billion which equals US$68 billion and will build production facilities that exceed current capacity by more than 100 times. The Brazilian Association of Biogas (Abiogás) made this ambitious estimate which shows that Brazil can turn organic waste into renewable energy resources because of its extensive organic waste resources.

A new regulatory system drives this expanding sector forward through its implementation of a resolution approved by the National Energy Policy Council (CNPE) which serves as its foundation. The regulation requires natural gas producers and importers to achieve emissions reductions of 0.5 percent through their biomethane usage in operational activities. Maria Clara Pontelli who works as a technical and regulatory analyst at Abiogás considers this target to be essential for the mission of her organization.

According to Pontelli, the new measures are vital because technical studies from Abiogás determined that the existing 0.25% target did not reflect current biomethane development in Brazilian industry. She explained that the 0.5% target better represents industry operations because it can be achieved with current resources and ongoing projects. The industry considers this regulatory progress to be an important achievement because it proves that Brazil has reached a stage where biomethane production has become established and it delivers clear economic signals which will attract future investments.

The policy establishes the Certificate of Origin Guarantee for Biomethane (CGOB) which will help create financial value for the environmental benefits associated with biomethane. This allows for the separation of the biomethane molecule's commercialization from its environmental attribute, broadening market reach and attracting diverse demand profiles, from industrial consumers to companies seeking to decarbonize their supply chains.

Overcoming Infrastructure Hurdles

The industry operations show great potential but face multiple difficulties that primarily stem from infrastructure needs. Biomethane production in Brazil operates as a decentralized system which establishes production sites near agro-industrial facilities and agricultural land and urban waste disposal points throughout the country. The natural gas pipeline system in Brazil only extends to coastal areas which creates difficulties for moving biomethane through the country.

"The situation requires new logistical models which include CNG truck road transport and decentralized consumption systems that work near production facilities," Pontelli explained. The CGOB will enable the organization to address a historical problem because it provides a dedicated tool which allows the assessment of biomethane's environmental value for fair competition with fossil fuels.

Current Landscape and Future Projections

Currently, Brazil boasts 19 ANP-authorized plants producing and commercializing biomethane, with a combined installed capacity exceeding 1.19 million cubic meters per day (Mm³/d). This figure doesn't include numerous units producing biomethane for self-consumption, particularly in rural and agro-industrial areas, suggesting the actual production volume is higher.

The growth trajectory is robust. The ANP reports 44 plants in the authorization process, projected to add approximately 1.77 Mm³/d by 2028. Looking further ahead, Abiogás estimates Brazil could reach 8 Mm³/d by 2032, with around 200 plants in operation. The theoretical potential, considering all organic waste, could even reach 120 Mm³/d.

Investments are expected to follow this growth, with the R$348 billion figure reflecting the long-term potential. The 0.5% target is crucial in reducing demand risk, making projects more bankable and aligning them with decarbonization strategies.

Key Projects and Financing

Biomethane production projects are predominantly concentrated in landfills, utilizing biogas for energy recovery, and in agro-industrial waste, particularly from the sugar-energy sector and animal waste. The sugar-energy sector, especially in the Southeast region, is anticipated to drive much of the future growth.

Financing for these projects is increasingly available, with the new regulatory target expected to further boost interest. Brazil's financial landscape offers a wide array of instruments, including the Climate Fund, Finame Low Carbon, Finem, RenovAgro, Inovagro, and Prodecoop, operated by the BNDES, alongside support from Finep and regional development banks.

Technological Advancements and Global Ambitions

Manuela Caiate, President of the Board of Directors at MDC Energia, highlighted the role of technology in the sector's evolution. "The possibility of always seeking the best technology, nationalizing equipment, has always been a concern, always seeking cost efficiency and, obviously, safety in the production process," Caiate noted. She also pointed to advancements in biomethane purification technologies and the increasing availability of gas-powered trucks and buses, which can run on both natural gas and biomethane.

Brazil is also looking beyond its borders, exploring the potential for biomethane exports, particularly in the maritime sector. Discussions within the International Maritime Organization (IMO) about low-carbon fuels for shipping present a significant opportunity. Caiate emphasized the efforts to position biomethane in this global market, working with associations in the US, Europe, and Canada.

"This creates a biomethane market more akin to a global commodity, integrating this market," Caiate stated, acknowledging it's a long-term plan. The country's commitment to sustainable fuels was also evident at COP30, where Brazilian entities advocated for a significant increase in renewable fuel production by 2035.

While the transition away from fossil fuels will be a gradual process, Brazil, with its 90% renewable electricity matrix, is focusing on decarbonizing other energy sectors. Biomethane, alongside ethanol and biodiesel, is seen as a crucial component of a diversified biofuel mix that will drive the country's energy transition, especially given the climate of insecurity produced by the war between the US and Iran and the closure of the Strait of Hormuz. The recent regulatory developments and the vast untapped potential position Brazil as a key player in the global biomethane landscape, offering a compelling model for circular economy and sustainable development.

From Trash to Fuel: Orizon (ORVR3) Unveils Massive Biomethane Project Serving 2.5 Million Brazilians

Brazilian waste management company Orizon dedicated a new biomethane plant at its Ecoparque Jaboatão facility located in Greater Recife Pernambuco through a financial commitment of 258 million reais which equals 51.6 million dollars. The facility transforms organic waste into biomethane which the company then supplies through its pipeline system to serve residential and industrial customers.

The plant began its construction process during May 2024 and finished building work by December 2025. The facility operates at a daily renewable gas output capacity of 108.000 cubic meters. Orizon CEO Milton Pilão reported that the company currently produces between 70.000 and 80.000 cubic meters of gas but plans to increase this output to 130000 cubic meters within one year and 150.000 cubic meters after two years.

The project handles 3.500 tons of waste material every day because it serves 2.5 million residents from Recife and adjacent municipalities. According to Priscila Krause who serves as Pernambuco's Vice-Governor and attended the inauguration ceremony Copergás will receive 5 of its entire gas distribution total from the biomethane which will be injected into the Copergás network. Copergás allocated 25 million reais to develop its pipeline system connecting to the Orizon facility.

Pilão also announced plans for three additional biomethane plants in Brazil's Northeast, specifically in Maceió (Alagoas), Aracaju (Sergipe), and João Pessoa (Paraíba), where Orizon operates landfills. Each of these future plants is estimated to require an investment of around 150 million reais, totaling approximately 450 million reais ($90 million), and are expected to become operational within the next two years.

The Ecoparque Jaboatão, which has been operating as a landfill for many years, received financing for the biomethane plant from Banco do Nordeste (BNB). The facility holds authorization from the National Agency of Petroleum, Natural Gas and Biofuels (ANP) to produce and commercialize biomethane since 2025. The ecopark spans 1.1 million square meters, receives over 550 trucks daily, and features Latin America's largest Mechanized Sorting Unit (UTM) and a 28.5 MW thermoelectric plant that converts biogas into electricity.

Orizon establishes itself as a major waste management company which operates 18 ecoparks throughout 12 Brazilian states to create waste valorization solutions that produce biomethane, biogas, recyclables, organic fertilizers, and carbon credits. Pilão explained that the "fuel of the future" laws which require natural gas pipelines to contain 10% biomethane create a market demand for biofuels which need governmental backing.

Renato Dutra, National Secretary of Oil, Natural Gas and Biofuels, representing Minister of Mines and Energy Alexandre Silveira, explained that the market would control how fast biomethane became more widely used. Orizon plans to develop liquefaction systems which will enable them to provide service to customers who lack access to their current gas pipeline system as part of their strategy to extend biomethane distribution across the entire country.

Brazil’s Major Cities Pivot to Biomethane to Decarbonize Public Transport

Brazilian municipalities are accelerating the adoption of biomethane-powered buses as a strategic alternative to diesel, citing lower costs and easier infrastructure integration compared to electric vehicle (EV) programs.

In Londrina, the Municipal Transit and Urbanization Company (CMTU) launched a 30-day trial of a 100% biomethane-powered bus on nine urban routes. The vehicle, a Marcopolo Volare Fly 10, will be tested for performance, fuel autonomy, and passenger comfort. Mayor Tiago Amaral noted that the initiative aligns with a broader plan to transform urban waste into fuel, creating a circular economy that benefits both the environment and local industry.

"We are starting a study to transform waste into gas," Amaral said. "It is better for nature and provides a cheaper fuel for our fleets and industries."

The shift comes as city officials face mounting pressure from volatile global diesel prices and the technical hurdles of electrification. In São Paulo, South America’s largest metropolis, Mayor Ricardo Nunes indicated that biomethane is now a key pillar of the city's decarbonization goals. The move follows significant delays in the city’s electric bus rollout, which has been hampered by a lack of charging infrastructure and disputes with power utility Enel.

According to city estimates, replacing diesel with biomethane could halve the annual R$3 billion (approx. $530 million) operating costs of São Paulo’s bus fleet. The city plans to leverage biomethane produced at local landfills, such as the East Waste Treatment Center (CTL), which processes 7,000 tons of household waste daily.

Industry experts argue that biomethane offers a more immediate solution than electricity. Marcelo Mendonça, Technical-Commercial Director at the Brazilian Association of Piped Gas Distributors (Abegás), pointed out that over 90% of São Paulo’s bus garages are already within one kilometer of existing gas distribution networks.

"The gas infrastructure is already there to allow for immediate use," Mendonça said.

In the state of Goiás, the capital Goiânia has embarked on an even more ambitious "New Metropolitan Public Transport Network" (Nova RMTC). The program aims to deploy 500 biomethane buses by the end of next year, with an initial investment of R$569.2 million ($100 million) shared between state and local governments. While biomethane vehicles have roughly 10% less autonomy than diesel counterparts, the fuel is approximately 15% cheaper per unit, and the acquisition cost of the buses is three times lower than that of electric models.

To support the transition, the Goiás state government has implemented tax incentives, including ICMS tax credits of up to 90% for biomethane producers and distributors, further cementing the fuel's role in Brazil's energy transition.

Summary of Key Developments:

• Londrina: 30-day trial of biomethane buses on nine routes; focus on waste-to-energy circular economy.
• São Paulo: Biomethane adopted as a pragmatic alternative to stalled electric bus expansion; potential to cut fleet costs by 50%.
• Goiânia: Goal of 500 biomethane buses by late 2025; R$569 million investment supported by state tax incentives.
• Environmental Impact: Biomethane reduces CO2 emissions by up to 95% and nitrogen oxide (NOx) by 85% compared to diesel.

Brazil Bets Big on Biomethane: Atvos Plans 7 New Plants to Slash Diesel Use by 88%

Brazilian energy company Atvos announced ambitious plans to construct seven new biomethane production plants across the country, which will enable the company to expand its renewable fuel portfolio while decreasing diesel consumption. The initiative shows Brazil's increasing dedication to energy transition which occurs during unpredictable international market conditions.

The first of these facilities, located in Mato Grosso do Sul, has already commenced industrial operations. The facility will create about 28 million cubic meters of biomethane during each harvest period by processing sugarcane waste. Atvos will use this renewable fuel to operate its own fleet which aims to achieve 100 percent diesel replacement for all operations within the next few years. Atvos will achieve production capabilities of 137 million cubic meters through the seven plants, which will result in more than 88 percent reduction of diesel emissions.

Governor Eduardo Riedel of Mato Grosso do Sul highlighted the project's alignment with the state's decarbonization and sustainable development strategies. Secretary Jaime Verruck emphasized biomethane's importance to the state's bioenergy policy and its 2030 carbon-neutral target. The project involved an investment exceeding R$350 million in Nova Alvorada do Sul, which serves as a critical milestone for diversifying the state's energy sources while boosting the competitiveness of its sugar-energy industry.

The Brazilian agricultural sector undergoes its second major advancement after biomethane expansion. The global cotton market is experiencing pressure from commodity price fluctuations which result in higher demand for less expensive synthetic fibers. An executive from Abra stated that global logistics systems face operational disruptions because the Strait of Hormuz remains blocked which adds to production expenses and creates medium-term price declines for cotton.

The results from commodity markets displayed different performance patterns. Chicago corn prices increased by 0.4% to reach $4.70 per bushel for the May contract because of rising oil prices. The price of corn has increased by 8.26% during the last month. The New York exchange experienced a 0.7% decline in raw sugar prices while cocoa registered a 0.3% increase. The rising oil prices will shift Brazilian sugarcane production toward ethanol production which will decrease global sugar availability. Brazil will produce approximately 4 billion liters more of ethanol during the 2026/2027 harvest which will create a new record for the country which holds the title of largest sugarcane producer: 36,66 billion liters.

The National Monetary Council approved a R$7.4 billion allocation for FUNCAF in 2026 which will support coffee supply chain processes from cultivation to commercialization and damaged crop recovery. The national budget already includes this funding. A court in Paraná confirmed its earlier decision which prevents Bela Agrícola from merging its R$2.2 billion unsecured debts into one extrajudicial recovery plan. The Chinese-controlled group needs to modify its approach.

Biomethane: Production and Applications

Biomethane (also referred to as renewable natural gas or RNG) is a sustainable, high-energy biofuel derived from the purification of biogas. Chemically nearly identical to conventional natural gas, it consists primarily of methane (CH₄) with a concentration typically exceeding 90–95%. As a renewable energy source, biomethane plays a pivotal role in the global transition toward a circular economy and the decarbonization of energy matrices, particularly in sectors such as heavy transportation and industrial manufacturing.

Production Process

The generation of biomethane is a multi-stage industrial process that begins with the production of raw biogas and concludes with advanced refining techniques.

Anaerobic Digestion

The primary source of biomethane is biogas, which is produced through the anaerobic digestion (decomposition in the absence of oxygen) of organic matter. Common feedstocks include:

• Agricultural Residues: Livestock manure and crop remains;
• Urban Waste: Organic fractions of municipal solid waste and sewage sludge;
• Industrial Byproducts: Waste from food and beverage processing.

This decomposition typically occurs in controlled environments known as biodigesters or naturally within sanitary landfills. Raw biogas generally contains 50–70% methane, with the remainder being carbon dioxide (CO₂) and trace amounts of nitrogen, hydrogen sulfide (H₂S), and moisture.

Purification and Upgrading

To transform biogas into biomethane, it must undergo a process known as upgrading. This involves three critical removal steps:

1. Desulfurization: The removal of hydrogen sulfide (H₂S) to prevent corrosion of metallic components and engines.
2. Dehumidification: The elimination of moisture (water vapor) to ensure stable combustion and prevent internal freezing or corrosion.
3. CO₂ Separation: The extraction of carbon dioxide to increase the energy density (calorific value) of the gas.

Various technologies are employed for CO₂ separation, including membrane separation, water scrubbing, and pressure swing adsorption (PSA). Once the methane concentration meets regulatory standards — such as those set by the National Agency of Petroleum, Natural Gas and Biofuels (ANP) in Brazil — the gas is classified as biomethane.

Economic and Environmental Significance

Biomethane is distinguished from other renewables by its interchangeability with fossil-derived natural gas. This allows it to utilize existing infrastructure, such as pipelines and Compressed Natural Gas (CNG) vehicles, without requiring specialized modifications.

Environmental Impact

By capturing methane — a potent greenhouse gas — from organic waste that would otherwise decompose in the open, biomethane production significantly reduces atmospheric pollution. When used as a substitute for diesel or gasoline, it can reduce greenhouse gas emissions by up to 99%. Furthermore, the byproduct of the digestion process, known as digestate, serves as a high-quality organic fertilizer, closing the nutrient loop in agricultural systems.

Energy Security and Circular Economy

Unlike fossil fuels, biomethane is produced locally from domestic waste streams, shielding national economies from international oil price volatility and exchange rate fluctuations. It embodies the principles of the circular economy by transforming an environmental liability (waste) into a strategic energy asset.

Market Outlook and Challenges

The adoption of biomethane is accelerating globally, supported by legislative frameworks such as "Future Fuel" mandates that require major gas importers and producers to integrate renewable molecules into their portfolios. However, several challenges persist:

• Complexity and Scale: Biomethane plants require higher capital investment (CAPEX) and operational expertise compared to simple electricity generation from biogas;
• Regulatory Compliance: Meeting stringent purity standards for injection into national grids requires continuous monitoring and sophisticated instrumentation, such as online chromatographs;
• Contractual Rigidity: Due to the necessity of constant supply for industrial clients, "take-or-pay" or "delivery-or-pay" contracts are common, increasing the legal and financial complexity for project developers.

As technology matures and carbon markets expand, biomethane is expected to remain a cornerstone of sustainable development, providing a versatile bridge to a low-carbon future.

Brazil’s First-Ever Biomethane Plant Powered by Pig Waste Is Set to Transform the Energy Sector

Brazil is set to inaugurate Latin America's first biomethane plant certified by the ANP (National Agency of Petroleum, Natural Gas and Biofuels) that uses swine waste. The facility, developed by H2A Bioenergia in partnership with Copercampos, will be launched on March 26 in Campos Novos, Santa Catarina, with an investment of R$ 65 million (approximately 13 million USD).

This certification allows for the formal commercialization of biomethane, ensures production traceability, and enables long-term contracts. The plant utilizes technologies such as CSTR biodigesters and membrane purification systems, achieving purity levels exceeding 96% — (Continuous Stirred Tank Reactor) is a type of chemical and industrial reactor where reactants flow continuously into a stirred tank and products exit simultaneously and it is characterized by perfect mixing, resulting in a uniform composition and constant temperature throughout its volume.

The plant will operate in the regulated biofuels market and will have the capacity to produce 16,000 m³ of biomethane, 23,000 m³ of biogas, and 12 tons of food-grade CO₂ daily. The project anticipates additional revenue through decarbonization credits under RenovaBio and carbon credits.

According to Adilson Teixeira Lima, CEO of H2A Bioenergia, the goal is to create replicable projects in agro-industrial dense areas. Data from ABiogas indicates that Brazil could produce over 80 billion m³ of biomethane annually from organic waste, primarily from the agricultural sector.

Biomethane is seen as a viable alternative for heavy transport and industry, offering a 96% reduction in greenhouse gas emissions in the regulated market. Heavy vehicles account for more than half of greenhouse gas emissions, despite representing only 5% of the total fleet. The energy transition process is slow, and solutions that work elsewhere may not be suitable for Brazil, with no single path to decarbonization.

Biomethane is considered the most viable solution for decarbonizing truck and bus fleets and can be produced from various sources. It has the potential for exponential growth in production and supply, creating jobs and income, and replacing diesel and LPG. Being derived from organic waste, it has a renewable carbon cycle and reduces greenhouse gas emissions by up to 90% compared to B15 diesel, depending on biomass origin and process efficiency. Brazil's encouragement of biofuels as a solution could help meet environmental targets sustainably, pave a sovereign path for economic growth, wealth creation, and global leadership in clean, renewable energy for mobility.

Comgás (CGAS5) Opens Call for Biomethane Plants as Brazil Eyes Major Gas Market Expansion

The Brazilian gas distributor Comgás announced that it has opened its public proposal period for connecting biomethane plants to its distribution network. 

Comgás will accept commercial proposals until March 30 for businesses that want to connect their biomethane plants to its distribution system. 

The public call was launched by the concessionaire located in São Paulo after Arsesp established the interconnection rules which determine how biomethane plants must connect to distribution networks. The agency also established aTusd-Verde distribution tariff system which allows producers to access a dedicated distribution rate. 

Comgás will present Arsesp with a business plan for plant interconnections in São Paulo state which they will complete by the end of June this year. 

The Usina Costa Pinto plant in Piracicaba and the Paulínia landfill currently maintain active connections to the Comgás distribution network. These two plants together supply the Comgás network with around 300.000 cubic meters of biomethane every day. 

The Brazilian Association of Biogas and Biomethane ABIOGÁS reports that Brazil produces 2 million cubic meters of daily biomethane. The organization ABIOGÁS believes that Brazil can raise its current output to 8 million cubic meters per day by the start of the next decade. Brazil has the ability to reach a production capacity of 120 million cubic meters per day by 2040 through appropriate investment strategies.

If this scenario materializes, Brazil could not only meet its domestic market demand but also export biomethane. This would allow the country to replace all currently imported Liquefied Petroleum Gas (LPG) in less than two decades and reduce diesel purchases by approximately 70% if biomethane is properly introduced into the transport sector, especially for heavy vehicles such as trucks and buses.

A study titled "Structuring Initiatives and Challenges to Boost Low-Carbon Mobility in Brazil by 2040," (Iniciativas e Desafios Estruturantes para impulsionar a mobilidade de baixo carbono no Brasil até 2040) conducted by LCA Consultores at the request of the MBCBrasil Institute, identifies biomethane as a key component in the decarbonization of heavy transport in Brazil, potentially leading to a new economic surge for the country.

Edge and Orizon Open Brazil’s Largest Biomethane Facility to Supply Industry and Transport

The biomethane plant, which Edge and Orizon opened last Saturday, serves as the company's largest facility and helps Brazil reach its energy transition goals while producing sustainable fuel. The facility, which operates in Paulínia, São Paulo state, located in southeastern Brazil, achieves a daily output of 225,000 cubic meters (m³/day), which supports the fuel needs of more than 1,000 urban buses.

The OneBio plant operates within an Ecopark that Edge (51%) and Orizon Valorização de Resíduos (49%) established as a joint project. The plant generates biomethane through its biogas treatment process, which extracts gas from urban solid waste streams. The plant operates its gas distribution system through existing pipeline connections while Edge manages its sales operations. Unilever has established a biomethane provision contract with Edge to support decarbonization efforts at its soap production facility located in Valinhos, São Paulo.

São Paulo leads Brazil in biomethane production, accounting for approximately half of the national capacity with nine operational units. The state currently has a production capacity of around 700,000 m³/day and expects to exceed 800,000 m³/day by December 2026, with a potential of 6.4 million m³/day.

The state expansion of natural gas and biomethane vehicle adoption proceeds through three policies which include environmental licensing simplification, natural gas and biomethane vehicle tax exemptions, and the "Conecta Biometano SP" platform. A 2025 regulation by ARSESP facilitates plant interconnection to the gas network, with costs covered by suppliers, aligning with the State Climate Change Policy (PEMC) and State Energy Plan (PEE 2050).

Biomethane functions as an industrial material which substitutes natural gas for two purposes. The FIESP study indicates that over 80% of São Paulo's biomethane potential lies in the sugar-energy sector which processes vinasse and filter cake and bagasse and straw.

Grupo Marquise in Ceará plans to spend R$100 million which equals $20 million USD for a new project that will create biomethane through solid waste processing at their Aquiraz landfill site. The GNR Fortaleza plant in Caucaia operates as the biggest facility of its type in North and Northeast regions because it produces 110000 m³ of output daily through its collaboration between Marquise Ambiental and Ecometano.

Cummins Brasil has begun field testing its B6.7N Otto cycle engine which represents the company's first medium engine designed for urban use that operates on natural gas and biomethane. This initiative supports Cummins' global "Destination Zero" strategy and provides an urban transport solution which operates more quietly and efficiently while meeting Euro VI and Proconve P8 standards through its dedicated system for continuous performance improvement.

From Landfills to Legislation: The Expansion of Brazil’s Biomethane Market

Brazil’s biomethane industry is gaining momentum as pioneering production projects converge with a new regulatory framework designed to expand the market and attract investment.

One of the sector’s landmark initiatives is located at the Dois Arcos sanitary landfill in São Pedro da Aldeia, Rio de Janeiro state. Operational since 2014, the facility became the first landfill in Brazil authorized to commercialize biomethane, receiving regulatory approval in 2017 from ANP, the National Agency of Petroleum, Natural Gas and Biofuels. Initially designed to produce around 16,000 cubic meters of biomethane per day, the plant has increased capacity to 18,480 m³/day through operational efficiency gains.

The landfill receives roughly 900 tons of municipal waste per day from eight municipalities, generating biogas through the anaerobic decomposition of organic material. The gas is captured through a network of more than 300 wells, about half of which remain active. Technicians continuously monitor methane concentrations and pressure levels to maximize gas recovery.

A key innovation at the site is its hybrid system, which allows biogas to be directed either to biomethane upgrading or to electricity generation. Higher-quality methane streams are routed to the biomethane plant, while lower-grade gas is used to produce power.

Beyond production, Brazil is also developing a regulatory ecosystem to support the biomethane market. Certification company, the Instituto Totum, founded in 2004, operates as a third-party agent providing verification, validation and certification services in various sectors, including biomethane.

A major regulatory milestone is the Fuel of the Future Law, whose discussions began in 2024 and which aims to expand biomethane use through the creation of the Biomethane Origin Guarantee Certificate (CGOB). The certificate separates the physical biomethane molecule from its environmental attribute, allowing producers to sell the fuel locally while trading the environmental credit independently. This mechanism is seen as particularly important in Brazil, where transporting biomethane over long distances can be logistically challenging.

The CGOB differs from the existing Gasc certification program, which primarily serves the voluntary market for biogas and biomethane. While Gasc uses a simpler purchasing process and measures gas in calorific value (millions of BTUs), CGOB focuses on biomethane that meets national fuel standards and measures volumes in cubic meters. The new system also requires buyers to participate directly in the registration and retirement of certificates, reflecting its more regulated structure.

Industry participants expect the new framework to stimulate investment and encourage biomethane production across the country. As the market expands, certification firms such as Toton are preparing to operate within the new system, ensuring transparency and preventing double counting between certification schemes while offering producers greater flexibility in how they commercialize their biomethane and associated environmental attributes.

The biomethane sector in Brazil is now poised for significant growth, driven by new policies aimed at increasing the share of renewable natural gas in the energy matrix. 

Although biomethane has been blended in places like Ceará into the gas network since 2018, the current production from 11 plants (840,000 m³/day) is minimal compared to Brazil's natural gas demand, which is 61 million m³/day. 

The main consumers include thermoelectric power plants, industrial users, and residential networks. The sector is expected to experience significant growth after 2026, when the Future Fuel Act will require gas distributors to blend biomethane with natural gas, starting at 1% this year and reaching 10% by 2035, with the goal of reducing fossil fuel consumption and greenhouse gas emissions.

Thus, under Brazil’s new regulatory framework, demand for biomethane is expected to rise sharply. Petrobras alone may require around 700,000 cubic meters of biomethane per day to comfortably meet its mandated blending quota, an amount that is nearly equal to the country’s current total biomethane production capacity.

Other distributors are also increasing their use of the renewable gas. São Paulo-based distributor Comgás already injects about 71,000 cubic meters of biomethane per day into its network, primarily supplied by a project in the city of Piracicaba. The company is now pursuing additional supply agreements as it prepares to expand biomethane use under the new regulations.

Brazil's Green Leap: Volare Launches Biomethane & Natural Gas Microbus for Sustainable Public Transport

The launch of the Volare Fly 10 GV microbus which operates on compressed natural gas and biomethane establishes a new sustainable mobility system in Brazil according to public transport specialists. The vehicle which Marcopolo S.A. (POMO3, POMO4), a Brazilian bus, coach and rail manufacturer produces at its São Cristóvão facility in Caxias do Sul, in the state of Rio Grande do Sul, represents multiple years of financial support for Brazilian engineering while providing an environmentally friendly option to replace diesel buses that still meet operational demands and flexible usage needs.

The microbus operates with an FPT Industrial N60 CNG engine which belongs to the Iveco Group and produces 200 horsepower together with 750 Nm of torque. The engine serves as a dedicated gas engine because it was not converted from diesel while delivering quieter operation and less need for maintenance and extending oil change intervals beyond standard diesel engine specifications.

The Volare Fly 10 GV can operate between 250 and 400 kilometers because its range depends on how people use it and the quality of the gas. The gas storage system of the vehicle has a capacity of 490 liters which it distributes across its four cylinders to provide enough operating time for urban and school and charter transport services. The vehicle has a gross vehicle weight of 10,700 kg and can carry up to 24 passengers in urban configurations or up to 54 students in school transport versions.

The microbus offers its main benefit because it uses biomethane as a sustainable fuel which comes from purified biogas that originates from the breakdown of organic material that includes agricultural waste and sewage and landfill waste. Biomethane power systems achieve substantial emission reductions because they produce 96 percent less particulate matter and 84 percent fewer greenhouse gases than diesel systems.

The vehicle features refueling speeds which match diesel bus refueling speeds and it contains certified high-pressure cylinders which have a 20-year operational lifespan because they adhere to strict safety requirements.

Volare, part of the Marcopolo Group and a leader in Brazil’s microbus segment for over 27 years, developed the Fly 10 GV after four years of testing and refinement. The company advocates this model as a bridging technology which connects traditional diesel buses with complete electric bus systems because it enables organizations to decrease emissions immediately without needing to construct new infrastructure.

The launch comes as Brazil expands its biomethane production capacity and seeks to integrate renewable fuels into its transportation sector. The Volare Fly 10 GV enables operators to use CNG and biomethane interchangeably which results in operational flexibility and lower carbon emissions and decreased fuel expenses and enhanced air quality.

The executives from the industry stated that their tested model has obtained positive results across different regions which included areas that have existing natural gas systems. The Brazilian microbus will operate urban transit systems and school transport programs while it will also serve charter fleets to support the country's development of renewable fuel-based transportation solutions.

The introduction of the Volare Fly 10 GV signals Brazil's increasing commitment to developing sustainable transportation solutions through the use of biomethane as a core element of its energy transition process.

Brazil and Biomethane: Renewable Gas Gains Strategic Ground as Minas Gerais Advances Regulation and Industry Scales Up

Brazil's biomethane industry is poised for significant growth, driven by increasing decarbonization pressures and recent regulatory advancements, particularly in the state of Minas Gerais. The renewable gas, produced from organic waste, is emerging as a strategic asset in the country's industrial decarbonization efforts, offering a pragmatic solution for sectors heavily reliant on fossil natural gas.

Biomethane's compatibility with existing gas infrastructure presents a decisive advantage for hard-to-electrify industries such as ceramics, glass, food processing, paper, and chemicals, allowing them to cut emissions without immediate equipment replacement.

Several factors are accelerating the biomethane market in Brazil, including growing pressure for decarbonization targets, rising demand for circular economy solutions, energy security concerns, and the volatility and higher costs of fossil gas. Unlike other clean energy alternatives, biomethane can often be injected directly into existing gas grids, reducing transition costs and operational disruption.

Brazil possesses significant structural advantages for biomethane production, combining large-scale agribusiness, a robust sugarcane industry, extensive urban waste generation, and an expanding gas market. Feedstocks like vinasse, filter cake from sugar-energy operations, livestock waste, industrial effluents, and municipal solid waste offer substantial technical potential, though current production remains below estimated capacity.

Despite a growing pipeline of projects, the sector faces challenges, including limited connection to gas distribution networks in some producing regions, high upgrading and purification costs for small-scale plants, and the need for long-term supply contracts to ensure price predictability. Regulatory fragmentation at the state level also poses a hurdle, risking isolated development rather than systemic scale.

A major step forward occurred on February 9, 2026, with the publication of Decree No. 49,172 by the Minas Gerais government. This regulation establishes operational guidelines for biogas, biomethane, and low-carbon hydrogen policies, alongside rules for sharing and integrating gas infrastructure. The decree implements State Laws 24,396/2023 and 24,940/2024, providing clearer frameworks for licensing, commercialization, certification, environmental standards, and economic incentives.

Minas Gerais currently boasts 453 million Nm³ per year of installed biogas capacity across 359 operational facilities, representing approximately 10% of national production. In 2025, the state inaugurated its first biomethane plant, operated by Zeg Biogás in Tupaciguara, with an investment of BRL 78.6 million. Two additional biomethane units are under authorization in Sabará, with a combined capacity of 108,000 Nm³ per day.

The decree also advances low-carbon hydrogen policy, detailing technical standards, certification mechanisms, and economic incentives to expand hydrogen's role in heavy industry, mobility, and energy storage.

Industrial investment is also expanding. MAT, a Brazilian manufacturer of gas cylinders and trailers, reported record revenues exceeding BRL 30 million last year from compression systems and accessories. Approximately 70% of the equipment sold in 2025 was for biomethane compression, storage, and transport. According to data from the International Center for Renewable Energy (CIBiogás), Brazil had 79 biomethane plants in 2025 (54 operational, 25 under implementation), with biomethane supply expanding 107% during the year.

MAT is now considering local production of compressors, currently imported from Italy, which could facilitate financing through Brazil’s Finame machinery credit program.

Biomethane's appeal in Brazil rests on three strategic pillars: immediate emissions reductions using available technology, valorization of environmental liabilities through waste recovery, and lower operational disruption compared to alternative decarbonization pathways. If infrastructure gaps and regulatory harmonization challenges are addressed, Brazil could become a global leader in renewable gas production. The market's maturation speed will be crucial, but the convergence of industrial competitiveness, circular economy, and energy transition suggests that renewable gas is moving to the core of Brazil’s low-carbon strategy.

Brazil Expands Biomethane Trucks as Renewable Gas Production Surges

Brazil is rapidly expanding its biomethane-powered heavy-duty vehicle fleet and production capacity, positioning the renewable gas as a key component in its energy transition and transport decarbonization strategy.

Biomethane output in São Paulo state alone is projected to surge by 50% in 2026 with the launch of seven new biogas plants, according to industry projections. This expansion is bolstering Brazil's renewable natural gas (RNG) infrastructure and aims to reduce reliance on diesel in freight transportation.

Swedish manufacturer Scania, an early entrant, is now facing competition from Chinese automaker JAC Motors, which is introducing new gas-powered heavy trucks. Brazilian logistics firm Green Cargo plans to deploy between 150 and 200 biomethane trucks over the next 12 months, partnering with major corporations including JBS, Suzano, Veracel, and Eldorado for vehicle validation.

Volkswagen Caminhões e Ônibus is also contributing, with its new Constellation Biomethane model joining the fleet of EcoUrbis, a São Paulo waste management concessionaire. The vehicle, customized for solid waste collection, can cut CO2 emissions by up to 90% compared to diesel models, the manufacturer stated.

In a significant investment, Brazilian engine maker MWM and Vamos Group, a leading truck and machinery rental company, are jointly investing 150 million Brazilian reais ($30 million) in a project to convert diesel trucks to operate on biogas. Vamos plans to deliver the first 100 converted units to Rio de Janeiro's municipal sanitation company, Comlurb, in the first quarter.

Experts highlight biomethane's strategic role in energy security, as it is domestically produced from local waste streams, offering stability against geopolitical factors affecting fossil natural gas. Academic research is focusing on upgrading biogas to biomethane and integrating plants into circular bio-refineries, further supporting technological development and sustainability standards.

Strategic Benefits of Biomethane

• Energy Security: Biomethane is domestically produced from local waste, reducing dependence on imports and geopolitical factors
• Economic Impact: Stabilizes energy prices, supports rural development, and creates qualified jobs
• Environmental: Reduces nitrate pollution, minimizes odors, and provides biofertilizer from digestate

Scale Considerations: Medium-sized biomethane plants offer the optimal balance between efficiency and environmental management. Small plants in small cities sometimes lack technical expertise or lack of qualified professionals in Brazil, while very large facilities face logistical challenges.

Transportation Applications: Biomethane trucks reduce greenhouse gas emissions while maintaining performance comparable to diesel vehicles. When produced at scale, biomethane can be price-competitive with fossil natural gas.

Brazil's Strategy

As Brazil expands biomethane production, renewable gas is becoming central to the country's decarbonization strategy, connecting waste management, energy independence, and sustainable freight transport.
