The proposed facility at the REPLAN (Paulínia) refinery remains in the project development phase and is pending a Final Investment Decision (FID) before construction can commence. By utilizing Honeywell UOP’s ETJ process, Petrobras intends to convert low-carbon ethanol into aviation fuel. Brazil is currently the world’s second-largest ethanol producer, accounting for nearly a quarter of global production, and its sugarcane-derived ethanol carries an extremely low carbon intensity (CI) score.
In the company press release, Honeywell leadership emphasized the strategic importance of utilizing regional agricultural strengths to scale renewable fuels.
“Honeywell has a long history of providing innovative process technologies and technical expertise to reduce the cost to produce renewable fuels and help customers leverage new feedstock options. With Honeywell’s ethanol-to-jet process technology, Petrobras is positioned to deliver low-carbon energy solutions leveraging abundant agricultural byproducts to create fuel, helping meet global demand.”
, Ken West, President and CEO of Honeywell Process Technology
Petrobras’ Broader SAF Strategy
This ETJ project represents a core component of Petrobras’ aggressive 2026-2030 Business Plan. According to the provided research data, the state-owned company is committing a $1.5 billion investment in biorefining, targeting 44,000 bpd of dedicated clean fuel capacity by 2030. Petrobras has been rapidly diversifying its SAF production pathways over the past few years.
In 2024, Petrobras licensed Honeywell UOP’s HEFA (Hydroprocessed Esters and Fatty Acids) technology to produce SAF and renewable diesel at the Presidente Bernardes Refinery (RPBC) using soybean oil and beef tallow. Furthermore, in December 2025, the company delivered its first commercial batch of co-processed SAF from its Duque de Caxias Refinery (Reduc), and in February 2026, it selected Topsoe’s HydroFlex technology for a massive waste and vegetable oil feedstock project at the Boaventura Energy Complex.
Industry and Regulatory Drivers
Meeting the 2027 Mandates
The push for scalable SAF production in Brazil is heavily driven by strict regulatory deadlines. Starting in 2027, airlines operating in Brazil must utilize SAF to comply with the United Nations’ ICAO CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation) mandates for international flights, alongside Brazil’s domestic “Future Fuel Law.”
To support this transition, the Brazilian government announced a $1.1 billion (6 billion reais) investment in 2024 through BNDES and Finep to bolster local SAF production. Honeywell executives noted that these factors perfectly position the region for rapid growth.
“Brazil has the scale, feedstock and technology partners needed to become a global powerhouse in sustainable aviation fuel. This project is a major milestone for the region and demonstrates how strategic collaboration can accelerate Brazil’s role in the energy transition.”

Infinium’s Project Atlas Selected for Sustainable Aviation Fuel Supply
Infinium’s Project Atlas chosen by SABA to supply sustainable aviation fuel certificates with American Airlines handling delivery and logistics.
This article is based on an official press release from Infinium.
In a significant step for the sustainable aviation fuel (SAF) market, Infinium and the Sustainable Aviation Buyers Alliance (SABA) have announced that Infinium’s Project Atlas was selected to supply SAF certificates under SABA’s next-generation procurement initiative. According to the official press release, the proposal was submitted jointly with American Airlines, which will take delivery of the physical fuel and manage logistics.
The agreement aims to accelerate the deployment of high-integrity, next-generation fuel pathways by converting corporate demand into long-term, bankable supply agreements. By securing these offtake contracts, developers like Infinium can better support project financing and scale their operations to meet the aviation industry’s growing decarbonization targets.
Project Atlas and eSAF Production Targets
Project Atlas is an electrofuel (eSAF) development project by Infinium Energy. The company stated in its release that the facility has a planned capacity of approximately 100,000 metric tons per annum (MTPA) and targets a 95 percent reduction in carbon intensity compared to traditional fossil jet fuel. This new facility builds upon the company’s previous commercial deployment efforts, specifically Project Pathfinder in Corpus Christi and Project Roadrunner in Pecos.
In addition to supplying SABA’s corporate buyers, Infinium noted that Project Atlas will produce EU-compliant RFNBO (Renewable Fuels of Non-Biological Origin) eSAF. This positions the project to serve the European market, where the ReFuelEU Aviation regulation mandates a 2 percent SAF blending requirement that began in 2025, scaling up to 20 percent by 2035. A dedicated sub-mandate for synthetic eSAF is also slated to take effect in 2030.
“Being selected for this SABA offtake agreement is pivotal for Project Atlas,” said Robert Schuetzle, CEO of Infinium, in the press release. “The agreement reflects growing commercial demand for next-generation power-to-liquid fuels and supports the continued development of new domestic production capacity.”
The “Book and Claim” Model
SABA’s procurement strategy relies on a “book and claim” model. According to the announcement, corporate customers purchase sustainable aviation fuel certificates (SAFc) to invest in SAF and claim the associated environmental benefits against their Scope 3 emissions. Meanwhile, the physical fuel is delivered to an aircraft operator, in this case, American Airlines.
American Airlines will serve as the physical user of the eSAF, marking its second eSAF agreement with Infinium. The airline’s participation enables the allocation of emissions reductions to SABA’s corporate members without requiring the fuel to be loaded onto the specific flights those corporate employees take.
“We believe voluntary corporate demand can be a catalytic spark to help new SAF production facilities get off the ground,” said Kim Carnahan, CEO of the Center for Green Market Activation and head of the SABA secretariat, in the company statement.
Jill Blickstein, Vice President of Sustainability at American Airlines, added in the release that working with Infinium helps accelerate the development of SAF technologies that have the potential to reach commercial scale at lower prices.
AirPro News analysis
We note that the selection of Project Atlas highlights a critical mechanism in the modern SAF economy: decoupling the environmental attributes of sustainable fuels from their physical delivery. For power-to-liquid eSAF pathways, which are highly scalable but currently capital-intensive, securing long-term, binding offtake agreements is often the final hurdle before reaching a Final Investment Decision (FID).
By aggregating corporate demand through SABA, which launched this specific procurement round in May 2025, buyers provide the financial certainty needed to build new plants. With initial production at Project Atlas expected by 2029, this deal underscores how corporate sustainability budgets are increasingly being leveraged to underwrite the physical infrastructure required for aviation’s energy transition.
Frequently Asked Questions
What is eSAF?
Electro-sustainable aviation fuel (eSAF) is a type of synthetic fuel produced using renewable energy and captured carbon dioxide. Infinium’s process converts waste CO₂ and renewable power into a drop-in aviation fuel that is compatible with existing aircraft engines and fueling infrastructure.
How does the book and claim system work for SAF?
The book and claim system allows companies to purchase the environmental benefits of SAF (the “claim”) via certificates, even if the physical fuel (the “book”) is used by a different operator. This enables corporate buyers to reduce their reported climate emissions while funding the production of sustainable fuels.
