Petrobras Chooses Honeywell UOP Ethanol-to-Jet Tech for SAF Facility
Petrobras plans a large-scale Sustainable Aviation Fuel facility using Honeywell UOP’s Ethanol-to-Jet technology at REPLAN refinery in São Paulo, Brazil.

This article is based on an official press release from Honeywell.
On April 14, 2026, Honeywell announced that Brazilian state-owned energy corporation Petrobras has selected Honeywell UOP’s Ethanol-to-Jet (ETJ) process technology for a proposed Sustainable Aviation Fuel (SAF) facility. According to the official press release, the planned installation will be located at Petrobras’ REPLAN refinery in São Paulo, Brazil, marking the first large-scale ETJ initiative in Latin America.
Once approved and fully operational, the facility is projected to produce up to 10,000 barrels per day (bpd), equivalent to 420,000 gallons per day, of SAF. The project aims to leverage Brazil’s highly efficient and abundant ethanol industry, which primarily utilizes sugarcane and other agricultural byproducts, to meet the escalating domestic and global demand for low-carbon aviation fuels.
Project Details and Strategic Context
Scaling Up Ethanol-to-Jet Technology
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.”

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.”
, José Fernandes, President of Honeywell Latin America
AirPro News analysis
We observe that Petrobras is employing a highly pragmatic “all-of-the-above” strategy to mitigate supply chain risks. By investing simultaneously in co-processing, HEFA technology, Topsoe’s HydroFlex, and now Honeywell’s ETJ technology, Petrobras is hedging its bets across multiple feedstocks, including soy, tallow, corn oil, and ethanol. This diversification ensures resilience against agricultural yield fluctuations and commodity price spikes.
Furthermore, this ETJ project underscores Brazil’s potential to become the “Saudi Arabia of SAF.” The country already possesses the massive agricultural infrastructure required for ethanol production; by integrating Honeywell’s advanced processing technology, Brazil is effectively moving up the value chain to export high-margin, low-carbon aviation fuels just as the 2027 CORSIA regulatory clock runs out.

Syzygy Plasmonics and IFC Partner on SAF Projects in Latin America
Syzygy Plasmonics and IFC sign a framework to develop SAF projects in Latin America, starting with a 350,000-gallon facility in Uruguay.

Syzygy Plasmonics and the International Finance Corporation (IFC) announced a framework agreement on August 18, 2026, to develop a pipeline of SAF projects across Latin America, beginning with a commercial-scale facility in Uruguay.
The partnership, detailed in a press release issued by Syzygy Plasmonics, pairs the company’s proprietary light-driven reactor technology with the IFC’s technical and commercial advisory services. The initiative targets emerging markets by utilizing regional renewable energy and biogas feedstocks to produce lower-carbon alternatives to conventional jet fuel.
The NovaSAF-1 project in Uruguay
The first project under this framework is NovaSAF-1, located in Durazno, Uruguay. The facility is projected to produce an estimated 350,000 gallons of SAF annually. Syzygy Plasmonics has set a target year of 2028 for the commencement of commercial-scale operations and initial fuel deliveries from the site.
NovaSAF-1 will utilize biogas sourced from the nearby Estancias Del Lago powdered milk plant. This biogas will be combined with Uruguayan renewable electricity to produce synthetic paraffinic kerosene. The production process integrates Syzygy’s light-driven technology with Fischer-Tropsch technology licensed from Velocys to maximize fuel output. According to Syzygy Plasmonics, this process yields an estimated reduction in lifecycle greenhouse gas emissions of up to 90 percent compared with conventional jet fuel.
Commercial backing and offtake agreements
The IFC framework agreement follows established commercial commitments for the NovaSAF-1 facility. On January 20, 2026, global commodities group Trafigura signed a binding six-year offtake agreement to purchase the entire production volume from the Uruguayan plant. The agreement also includes an option for Trafigura to purchase additional volumes from future Syzygy projects.
Syzygy Plasmonics CEO Trevor Best described the commercial arrangements as a critical step toward commercial-scale impact and disrupting the SAF market. The IFC, a member of the World Bank Group, will provide advisory support to help scale these operations across the region.
“The transition to lower-carbon aviation will depend on technologies that are not only innovative, but commercially viable and scalable,” said Raphaël Eskinazi, IFC Regional Investment Manager for Manufacturing and Forests in Latin America and the Caribbean. “IFC’s role is to help bridge that transition: supporting pioneering projects that can mobilize private capital, demonstrate new business models and create pathways for broader market adoption across emerging economies.”
AirPro News analysis
We view the alignment of IFC advisory services, Trafigura’s guaranteed offtake, and Velocys’ established Fischer-Tropsch technology as a significant de-risking mechanism for Syzygy Plasmonics. Scaling novel SAF production methods, particularly those categorized as Renewable Fuels of Non-Biological Origin (RFNBO), typically faces steep financing hurdles. By securing a guaranteed buyer for 100 percent of the initial plant’s output before finalizing the IFC framework, Syzygy has demonstrated a clear path to revenue.
Latin America presents a highly favorable environment for RFNBO production. The region offers abundant agricultural waste for biogas and a growing grid of renewable electricity. If NovaSAF-1 meets its 2028 production targets, the framework agreement with the IFC positions Syzygy to replicate this model rapidly across other agricultural and renewable energy hubs in the Southern Hemisphere.

UK, Google and NATS Launch Contrail Avoidance Trial
Operation Blue Skies is a £5M, 30-month trial targeting contrail reduction across Shanwick oceanic airspace.

A consortium led by the UK government, Google, and air navigation service provider NATS has launched a £5 million, 30-month trial to mitigate aviation-induced warming contrails across the entire Shanwick oceanic airspace.
Announced on August 18, 2026, in a Google press release, “Operation Blue Skies” marks the commercial aviation industry’s first attempt to implement contrail avoidance at the scale of an entire flight corridor rather than on a per-airline basis. The initiative targets a phenomenon responsible for approximately one-third of the sector’s total climate impact.
Scaling AI for airspace-wide mitigation
The program will conduct two operational trials during the winters of 2026-2027 and 2027-2028. Testing will take place exclusively within the NATS-controlled Shanwick oceanic airspace, which encompasses the eastern half of the North Atlantic corridor. According to Google, this specific airspace accounts for roughly 5 percent of global contrail warming.
Google UK is participating on a pro-bono basis, providing a £1.4 million in-kind contribution that includes artificial intelligence research, engineering resources, and computing infrastructure. Google Technical Program Manager Paul Hodgson and Senior Program Manager Chaim Langermann described the initiative as “the world’s first state-backed trial to avoid contrails at the scale of an entire oceanic airspace.”
The broader consortium includes the UK Department for Transport (DfT), the Met Office, Contrails.org, Imperial College London, the University of Cambridge, and the Aerospace Technology Institute (ATI).
“We’re partnering with Google to back British experts and innovators to find practical ways to make flying cleaner. This is a world-first, and it is British ingenuity leading the way. By testing small tweaks to flight paths over the Atlantic, we can cut the vapour trails left behind by planes,” said UK Government Minister for Aviation, Maritime and Freight Keir Mather, according to reporting by Smart Cities World.
Transitioning from individual flights to systemic integration
Operation Blue Skies builds upon earlier research validating the use of AI-powered forecasts to predict and avoid contrail-forming regions. Google Research previously partnered with American Airlines, EUROCONTROL’s Maastricht Upper Area Control Centre (MUAC), and FlightKeys to demonstrate that contrail avoidance is scientifically and operationally viable for individual flights.
The new trial shifts the operational coordination to the air navigation service provider. By integrating predictive models directly into the airspace management level, NATS and its partners aim to evaluate how contrail mitigation impacts overall airspace capacity, controller workload, and flight efficiency across a high-density oceanic routing system.
AirPro News analysis
We view the shift from individual airline dispatch trials to an air navigation service provider-led model as a critical maturation in aviation sustainability efforts. If NATS can successfully integrate AI-driven contrail forecasting into the Shanwick oceanic clearance process without degrading airspace capacity or significantly increasing fuel burn, it could establish a blueprint for global air traffic management. The winter testing windows are particularly relevant, as atmospheric conditions during these months are highly conducive to persistent contrail formation over the North Atlantic. The results of this 30-month program will likely dictate whether regulators and service providers mandate contrail avoidance routing in the next decade.

ZeroAvia Leads HyPRIME Liquid Hydrogen Refuelling Project
ZeroAvia leads Project HyPRIME, backed by over £2 million in UK funding to test mobile LH2 refuelling at commercial airports.

ZeroAvia is leading a newly formed consortium to develop and test a mobile liquid hydrogen (LH2) refuelling vehicle at commercial airports in the United Kingdom, backed by over £2 million in government funding.
The initiative, known as Project HyPRIME (Hydrogen Propulsion Refuelling Infrastructure Mobile Ecosystem), was officially announced by the UK Department for Transport (DfT) and Innovate UK on July 23, 2026. ZeroAvia formally highlighted its leadership of the project on August 4, 2026. The consortium aims to demonstrate that hydrogen-electric aircraft can be refuelled within standard commercial turnaround times.
Advancing liquid hydrogen infrastructure
The HyPRIME consortium includes ZeroAvia as the lead partner, alongside ULEMCO Ltd, GeoPura Ltd, Bristol Airport Ltd, and Birmingham Airport Ltd. The group is tasked with designing, building, and testing a mobile refuelling system capable of supporting commercial hydrogen-electric aircraft operations.
A key technical objective of the project is the capture and utilization of “boil-off” hydrogen. Rather than venting this gas, the system will redirect it to fuel hydrogen-powered Ground Support Equipment (GSE), such as aircraft tugs, and on-site power generation units. The findings from these tests will inform future regulatory, safety, and infrastructure investment decisions for scaling LH2 fuel across the UK aviation sector.
Airport integration and sustainability targets
Testing and demonstrations for the mobile refuelling vehicle will take place in live commercial airport environments at Birmingham Airport (BHX) and Bristol Airport (BRS). Integrating cryogenic fuels into active aprons requires coordination with regulators, including the UK Civil Aviation Authority (CAA), to establish safe handling procedures.
Tom Denton, Head of Sustainability at Birmingham Airport, stated that hydrogen electric aircraft are progressing quickly and airports need to understand how the fuel can be safely and efficiently integrated into daily operations.
“HyPRIME gives us the opportunity to test procedures and build the knowledge required to support future zero emission flights from Birmingham. Taking part in this project helps us maintain the momentum we’ve built over the past few years and moves us that bit little closer to achieving our mission of running a lower carbon airport,” Denton said in a press release.
Birmingham Airport recently reported an 11% reduction in location-based greenhouse gas emissions for 2025/26 and has set a target year of 2033 to achieve net zero carbon emissions from its direct operations. Bristol Airport is also expanding its hydrogen footprint, having been announced on July 23, 2026, as a partner in the CHOSAN (Cryogenic Hydrogen Optimised Systems for AviatioN) project, which aims to deliver the first flight of a liquid hydrogen-powered aircraft from a UK commercial airport.
Government funding and strategic partnerships
Project HyPRIME is funded under the UK Government’s Zero Emission Flight Demonstrator Programme. According to Bristol Airport, the total funding pool for the program is £8 million. Reporting by BusinessGreen indicates that over £2 million of that total was specifically awarded to the HyPRIME initiative.
The announcement follows a series of strategic agreements for ZeroAvia in July 2026. On July 8, 2026, the company announced a collaboration with Marshall Aerospace to explore hydrogen-electric capabilities for military and defense platforms. On July 17, 2026, ZeroAvia and Safran forged a partnership to develop high-temperature hydrogen fuel cells for aviation applications.
AirPro News analysis
We view Project HyPRIME as a necessary step in bridging the gap between hydrogen aircraft development and practical airport operations. While powertrain technology has advanced rapidly, the logistical challenge of handling cryogenic liquid hydrogen on a busy commercial apron remains a significant hurdle. By testing boil-off capture for GSE, the consortium is addressing both safety and economic efficiency. Proving that LH2 can be managed within standard turnaround times without disrupting existing airport operations will be essential for securing regulatory approval and driving future infrastructure investments.
