On August 6, 2026, American Airlines and Infinium completed the first commercial passenger flight powered by electro sustainable aviation fuel (eSAF), marking the initial delivery of a non-biobased sustainable aviation fuel to a United States commercial airport. The flight operated from Corpus Christi International Airport (CRP) to Dallas Fort Worth International Airport (DFW).

In a joint press release issued on August 6, the companies confirmed that the eSAF was produced at Infinium’s Pathfinder facility in Corpus Christi, Texas. The operation demonstrates the real-world compatibility of next-generation, drop-in synthetic fuels with existing aviation supply chains and aircraft engines. The fuel was blended with conventional JetA aviation fuel and tested to meet ASTM International specifications, certifying its use without requiring modifications to current fueling infrastructure or aircraft.

Scaling synthetic fuel production

Infinium has been operating its Pathfinder facility since 2023, functioning as the first commercial-scale power-to-liquids eFuels production site globally. The facility utilizes waste carbon and renewable energy to produce scalable, drop-in synthetic fuels. According to Infinium, its eSAF can deliver an estimated reduction in lifecycle greenhouse gas (GHG) emissions of over 90 percent compared to conventional petroleum-based jet fuel.

“Since 2023, we have been producing scalable, drop-in eDiesel and eNaphtha at our Pathfinder facility from waste carbon and renewable energy for use in commercial trucks and plastics processing,” said Infinium CEO Robert Schuetzle in the press release.

American Airlines CEO Robert Isom emphasized the necessity of transitioning these technologies from the investment phase to operational reality. Isom stated that scaling sustainable aviation fuel (SAF) production at lower prices is essential for reducing emissions, strengthening long-term competitiveness, and maintaining the connectivity that passengers rely on.

Corporate partnerships and future offtake agreements

The August 6 flight serves as a precursor to larger commercial agreements between the two companies. American Airlines holds an existing offtake agreement for commercial volumes of eSAF from Infinium’s upcoming Project Roadrunner facility, which is currently under construction. Production and deliveries from Project Roadrunner are expected to begin in 2027.

The expansion of Infinium’s production capacity is supported by significant financial partnerships. Project Roadrunner is financed by Breakthrough Energy Catalyst and Brookfield Asset Management, with nonrecourse project debt provided by HSBC.

The American Airlines offtake agreement is partially supported by a separate arrangement with Citi, designed to enable Scope 3 emissions reductions from employee travel. Edward Skyler, Head of Enterprise Services and Public Affairs at Citi, noted that the first-of-its-kind flight represents a critical step for lower-carbon aviation, adding that the financial institution looks forward to efforts aimed at scaling SAF production.

The successful deployment of eSAF on a commercial passenger flight represents a technical milestone for the aviation industry, which has historically relied on biobased feedstocks like used cooking oil or agricultural waste for SAF production. Because biobased feedstocks face inherent scalability and land-use constraints, power-to-liquid synthetic fuels offer a theoretically limitless production pathway, provided there is sufficient access to renewable electricity and captured carbon. We view the involvement of major financial institutions like Citi, Brookfield, and HSBC as a strong indicator that capital markets are beginning to validate the commercial viability of eFuels. The primary hurdle remains the unit cost of production. The transition from the Pathfinder facility’s initial output to the larger-scale Project Roadrunner in 2027 will be a critical test of whether eSAF can achieve the price parity necessary for widespread airline adoption.

On June 29, 2026, KBR announced its selection by Keppel Ltd. and Aster Chemicals and Energy to provide technology licensing and Front-End Engineering Design (FEED) services for a proposed 100,000-ton-per-year SAF (SAF) facility on Jurong Island, Singapore.

The planned facility is envisioned as Asia’s first commercial-scale ethanol-to-jet (EtJ) SAF plant. According to the KBR press release, the project will utilize the company’s PureSAF technology to produce a 100% drop-in jet fuel, supporting Singapore’s national mandate to increase sustainability usage across the aviation sector.

PureSAF technology and project scope

The Jurong Island facility will leverage PureSAF, a technology originally developed by Swedish Biofuels AB and engineered for commercial-scale production by KBR, which holds the exclusive global license. The process is designed to convert ethanol into aviation fuel that requires no blending with conventional Jet A or Jet A-1 before use.

In a statement accompanying the announcement, KBR President and CEO Stuart Bradie highlighted the system’s flexibility.

“KBR’s PureSAF is a feedstock-flexible, bankable technology that is designed to deliver a 100% drop in jet fuel, ready to power aircraft without blending. We are constantly innovating our SAF solution to make it compatible with feedstock availability in different regions and to enable the aviation industry to transition to low-carbon jet fuel with a cost-optimized approach.”

The FEED study will determine the technical configuration and project capital expenditure required for the facility. The development remains subject to regulatory approvals and a final investment decision (FID) by the project partners.

Aligning with Singapore’s aviation mandates

The selection of KBR follows a January 28, 2026, agreement between Keppel’s Infrastructure Division and Aster to jointly assess the development of the Jurong Island site. Aster operates as a joint venture between Indonesian petrochemical company Chandra Asri and Swiss commodities trader Glencore.

The proposed 100,000-ton annual production capacity aligns directly with targets set by the Civil Aviation Authority of Singapore (CAAS). Starting in 2026, the CAAS mandates a 1% SAF uplift for all departing flights from the country, with a stated goal of increasing that requirement to between 3% and 5% by 2030.

Alongside the SAF plant contract, KBR and Keppel signed a Memorandum of Intent to collaborate on broader energy transition initiatives. The companies plan to explore technologies related to waste-to-energy, plastic recycling, biofuels, and artificial intelligence-driven digitalization.

We view the progression of the Jurong Island project to the FEED stage as a critical indicator of the Asia-Pacific region’s readiness to scale SAF production. While North America and Europe have led early SAF capacity investments, Singapore’s firm regulatory mandate provides the demand certainty required to underwrite commercial-scale facilities in Southeast Asia. The choice of an ethanol-to-jet pathway is particularly notable, as it allows operators to bypass the constrained supply of fats, oils, and greases that limit hydroprocessed esters and fatty acids (HEFA) production volumes. The project’s ultimate realization hinges on the upcoming final investment decision, which will test the commercial viability of the EtJ process in the current economic environment.

A coalition of environmental and industry non-governmental organizations is urging the European Commission to end the European Union Emissions Trading System exemption for international flights, a move proponents estimate could generate €130 billion in carbon market revenues between 2027 and 2035.

In a campaign coordinated by the SASHA Coalition, groups including Opportunity Green, Transport & Environment, and Carbon Market Watch are targeting the upcoming legislative revision of the European Union Emissions Trading System (EU ETS) scheduled for July 2026. The coalition argues that integrating extra-EEA flights into the carbon pricing mechanism is necessary to fund clean aviation technologies, specifically electro-Sustainable Aviation Fuel (eSAF) and Direct Air Capture (DAC) infrastructure.

The financial and environmental cost of the exemption

The European Union initially included aviation in the ETS on January 1, 2012, but introduced a stop-the-clock mechanism exempting extra-EEA flights following international pressure. According to a policy briefing from the SASHA Coalition, this exemption left an estimated 1.1 billion tonnes of carbon dioxide emissions unregulated between 2012 and 2023. The coalition calculates this resulted in €26 billion in uncollected carbon market revenues during that period.

If the exemption is maintained after its scheduled expiration in 2027, the coalition projects that 1.3 billion tonnes of carbon dioxide emissions will go unregulated through 2035. A full-scope ETS could generate an estimated €14 billion in annual revenue for European Union member states by 2030.

Industry perspectives on carbon pricing and CORSIA

The debate centers on the effectiveness of the United Nations Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). The European Commission is required to assess by mid-2026 whether CORSIA delivers sufficient environmental ambition. Environmental groups argue the UN scheme is structurally unfit because it relies on offsetting rather than absolute emissions reduction and targets only emissions above a high baseline. Conversely, Airlines and industry groups have historically opposed extending the EU ETS to international flights, citing concerns over market distortions, potential violations of international law, and competitive disadvantages for European hubs.

Clean technology providers argue that a strong regulatory framework is required to drive investment. During a June 9, 2026 roundtable event at the European Parliament convened by the SASHA Coalition, NEG8 Carbon Head of Business Development Dr. David Mulrooney emphasized the necessity of the ETS for commercial strategy.

“To answer your question directly: the EU ETS is foundational to our commercial strategy. NEG8 supplies atmospheric CO2 capture. The stronger and more consistent the carbon price signal, the stronger the investment case for the infrastructure we sell into. ETS is not a policy backdrop for us. It is the market mechanism our business is built on,” Mulrooney stated.

Mulrooney advocated for directing ETS revenue into DAC and eSAF to drive down costs, similar to historical cost curves for solar power and batteries. Member of the European Parliament Cynthia Ní Mhurchú also spoke at the event, noting that regulatory certainty is critical for future planning.

The July 2026 review of the EU ETS represents a critical juncture for European aviation policy. We observe that the European Commission is caught between two competing pressures: the mandate to meet aggressive decarbonization targets and the risk of triggering international trade disputes if it unilaterally prices emissions on extra-EEA flights. The SASHA Coalition focus on revenue generation for eSAF and DAC is a strategic pivot, framing the ETS not just as a punitive tax but as a necessary funding mechanism for the aviation industry transition. Overcoming airline opposition to overlapping carbon pricing regimes will require the Commission to clearly articulate how the EU ETS and CORSIA can coexist without creating prohibitive administrative and financial burdens for operators.
