FAA Approval of Ampaire’s Hybrid-Electric Propulsion: A Leap Toward Sustainable Aviation

The aviation industry stands at a crossroads. With mounting pressure to reduce carbon emissions and operating costs, innovation in propulsion systems has become a necessity. Ampaire, a California-based aerospace company, has taken a significant step in this direction with the Federal Aviation Administration’s (FAA) approval of the G-1 Issue Paper for its AMP-H570 hybrid-electric propulsion system.

This regulatory milestone not only validates Ampaire’s technological approach but also sets a precedent for certifying hybrid-electric aircraft systems. The AMP-H570, designed to retrofit existing aircraft like the Cessna Caravan, aims to drastically reduce fuel consumption and emissions, offering a practical and scalable solution for regional air travel. This article explores the technical, regulatory, and market implications of this development and what it means for the future of aviation.

Understanding the AMP-H570 System and Certification Process

The Hybrid-Electric Architecture

The AMP-H570 propulsion system is built on a parallel hybrid-electric architecture. This configuration combines a conventional combustion engine with electric motors and a battery system, enabling performance optimization across various flight phases. During takeoff and climb, both the combustion engine and electric motors work in tandem to deliver maximum thrust. During cruise, the combustion engine takes over, while the battery recharges through a regenerative generator.

This system eliminates the need for ground-based charging infrastructure, a significant advantage in remote or underdeveloped regions. The design is modular and retrofit-ready, allowing operators to upgrade existing fleets without requiring extensive modifications or new ground support systems.

Notably, the AMP-H570 has demonstrated compatibility with 100% Sustainable Aviation Fuel (SAF) during ground tests, further enhancing its environmental credentials. The system’s integrated battery management and power electronics ensure seamless energy distribution and real-time optimization based on flight conditions.

“The FAA’s issuance of the G-1 Certification Basis for the AMP-H570 is a major step forward in commercializing hybrid electric propulsion,” Kevin Noertker, CEO, Ampaire

The FAA Certification Journey

The FAA’s certification process for a new propulsion system is rigorous and multi-staged. The G-1 Issue Paper, recently approved for the AMP-H570, establishes the certification basis, including airworthiness and environmental standards under 14 CFR Part 33. This is the foundational step in achieving Supplemental Type Certification (STC).

The next phase, the G-2 Issue Paper, will define the Means of Compliance—essentially how Ampaire will demonstrate that the system meets the required standards. This involves a combination of flight tests, simulations, and data analysis. Following that, the G-3 phase will address environmental considerations such as noise and emissions. The final step is obtaining the STC itself, which would allow for commercial deployment.

Ampaire is currently working closely with the FAA to finalize the G-2 phase and expects to complete testing and certification by the end of 2026. This timeline aligns with broader industry goals for reducing aviation emissions and transitioning to sustainable technologies.

Market Impact and Industry Implications

Economic and Environmental Advantages

The AMP-H570 system offers compelling economic benefits. By reducing fuel consumption by up to 70% and lowering maintenance costs, the system can cut overall operating expenses by 25–40%. These savings are particularly significant for regional airlines operating on thin margins.

In flight tests, Ampaire’s Eco Caravan—a modified Cessna Grand Caravan equipped with the AMP-H570—demonstrated more than double the fuel efficiency of conventional aircraft. When powered by SAF, emissions are nearly zero, aligning with international climate goals and regulatory frameworks.

These performance metrics make hybrid-electric aircraft a viable alternative for short-haul routes, where the economics of electric propulsion can be most effectively realized. The plug-and-play retrofit model also means faster deployment and lower upfront investment for operators.

Scaling the Hybrid-Electric Market

The hybrid-electric aircraft market is poised for exponential growth. Valued at approximately $1.1 billion in 2022, the market is projected to reach $12 billion by 2030. This growth is fueled by advancements in battery technology, increasing regulatory support, and rising demand for sustainable transportation options.

Ampaire’s strategic partnerships with organizations like Air France Industries KLM Engineering and Maintenance and Monte Air underscore its leadership in this space. Monte Air, for instance, has placed an order for up to 50 Eco Caravans, signaling strong commercial interest in the technology.

The U.S. Air Force has also funded research to integrate the AMP-H570 into the Beechcraft King Air platform, highlighting the system’s potential in military applications. This dual-use capability enhances the system’s market viability and opens new avenues for adoption.

“The most practical way to achieve an all-electric future is to jump-start the market with a partially-electric present,” Kevin Noertker, CEO, Ampaire

Challenges and Future Outlook

Despite the promising outlook, several challenges remain. The FAA’s certification process is comprehensive and resource-intensive. Any delays in the G-2 or G-3 phases could impact Ampaire’s deployment timeline. Additionally, the FAA has faced staffing shortages, which may further complicate the approval process.

On the production side, scaling up to meet demand will require robust supply chain management and manufacturing capabilities. Ampaire must also ensure that its systems maintain reliability and performance standards across different aircraft platforms and operating environments.

Nevertheless, the company’s modular design approach and focus on retrofitting existing aircraft provide a strategic advantage. By avoiding the complexities of clean-sheet aircraft development, Ampaire can bring its technology to market faster and with lower risk.

Conclusion: Bridging Today and Tomorrow in Aviation

The FAA’s approval of the certification basis for Ampaire’s AMP-H570 propulsion system marks a pivotal moment in the evolution of aviation. It validates a technology that offers immediate environmental and economic benefits while laying the groundwork for a more sustainable future.

As the industry strives toward net-zero emissions, hybrid-electric systems like the AMP-H570 offer a pragmatic and scalable solution. By bridging the gap between conventional and fully electric aircraft, Ampaire is not only advancing technology but also redefining what’s possible in regional and commercial aviation.

SABA Members Back Infinium eSAF Facility With Long-Term Deals

Google, McKinsey, and others sign binding SAFc agreements to support Infinium Energy’s 100,000 MT/year Texas eSAF project.

SABA Members Back Infinium eSAF Facility With Long-Term Deals

Corporate members of the Sustainable Aviation Buyers Alliance (SABA) have signed binding, multi-year agreements to purchase sustainable aviation fuel certificates (SAFc) from Infinium Energy’s planned electro-sustainable aviation fuel (eSAF) facility in Texas. The commitments, announced on September 22, 2026, are designed to provide the financial demand signals necessary for Infinium to reach a final investment decision on the project.

In a press release issued by SABA, the organization confirmed that American Airlines (AA) will serve as the physical offtaker for the fuel, managing logistics and delivery. The corporate buyers purchasing the associated certificates include AVEVA, Bain & Company, Google, and McKinsey & Company. The agreement marks the first time SABA’s procurement model has been utilized to directly drive new production capacity for scalable sustainable aviation fuel.

Project Atlas production and environmental targets

Infinium Energy was selected through a SABA procurement process earlier in 2026 to provide ultra-low carbon eSAF. The fuel is produced using waste carbon dioxide and renewable energy, distinguishing it from traditional biofuel pathways that rely on agricultural or waste feedstocks.

The planned Texas facility, designated Project Atlas, is expected to have an annual sustainable aviation fuel (SAF) production capacity of 100,000 metric tons. According to the alliance, the contracted volumes will support an expected greenhouse gas abatement of 212,000 metric tons of carbon dioxide equivalent (mtCO2e). SABA equates this emissions reduction to approximately 3,500 commercial flights between John F. Kennedy International Airport (JFK) and Los Angeles International Airport (LAX).

“We’re proud to partner with SABA members including AVEVA, Bain & Company, Google, McKinsey, and others, as well as American Airlines to bring Infinium Energy’s next world scale eSAF facility to life. Their commitment reflects a shared conviction that decarbonizing aviation requires real investment in next-generation supply,” said Robert Schuetzle, CEO of Infinium Energy.

Aggregating demand through book-and-claim

The transaction utilizes a book-and-claim model. Corporate buyers purchase the SAFc to claim the environmental benefits against their business travel emissions, while the physical fuel is delivered to partner airlines. This mechanism allows corporations to fund SAF production even when the physical fuel cannot be delivered directly to the airports their employees use.

American Airlines will manage the physical integration of the eSAF into the commercial aviation fuel supply chain. Jill Blickstein, Chief Sustainability Officer at American Airlines, stated that the corporate commitments broaden participation in the SAF market and demonstrate how customers can collaborate with airlines and fuel producers to advance decarbonization.

SABA, a joint initiative of the Environmental Defense Fund (EDF), the Center for Green Market Activation (GMA), and RMI, has aggregated $500 million in SAFc demand from 35 companies to date. Aviation currently accounts for approximately 2 to 3 percent of global greenhouse gas emissions.

“Novel technologies are critical to meeting future demand for sustainable aviation fuel, but they will not be operational in time without investments made today. This procurement demonstrates how aggregated, long-term demand can help take promising eSAF projects from idea to reality,” said Jon Creyts, CEO of RMI.

AirPro News analysis

We view this agreement as a critical structural step for the eSAF market. Power-to-Liquid (PtL) fuels like those planned for Project Atlas face a steep commercialization barrier. They are highly capital-intensive to build and currently produce fuel at a significant cost premium compared to both conventional Jet A and HEFA-based SAF derived from waste fats and oils.

Airlines operate on thin margins and generally cannot absorb the full green premium of eSAF alone. By unbundling the environmental attributes from the physical fuel, the SABA model allows highly capitalized corporate entities like Google and McKinsey & Company to absorb that premium. More importantly, signing binding, multi-year offtake agreements provides the revenue certainty that infrastructure lenders require before financing first-of-a-kind industrial facilities. If Project Atlas reaches a positive final investment decision based on these contracts, it will validate the book-and-claim model as a viable financing mechanism for next-generation aerospace infrastructure.

EU Exceeds 2025 SAF Mandate at 2.79 Percent Blend Rate

EASA reports EU airports hit 2.79% SAF blend in 2025, surpassing the 2% ReFuelEU mandate with 1.1M tonnes supplied.

Published

on

The European Union surpassed its initial Sustainable Aviation Fuel (SAF) mandate in 2025, with SAF accounting for 2.79 percent of all jet fuel supplied to EU airports during the first mandatory reporting year.

According to the 2026 ReFuelEU Aviation Annual Technical Report published by the European Union Aviation Safety Agency (EASA) on September 17, 2026, fuel suppliers delivered 1.1 million tonnes of SAF against a total aviation fuel supply of 39.3 million tonnes. The 2.79 percent blend rate comfortably exceeded the 2 percent minimum required by the ReFuelEU regulation for 2025. This uptake resulted in an estimated reduction of 3.77 million tonnes of CO2 equivalent greenhouse gas emissions.

“We are pleased to confirm that the SAF mandate under ReFuelEU Aviation was not only met but exceeded,” EASA Executive Director Florian Guillermet stated in the agency’s press release.

Compliance and distribution across European hubs

The EASA report indicates high compliance rates across the sector. Ninety-three percent of aircraft operators and 90 percent of fuel suppliers fulfilled their reporting obligations in 2025. EASA noted that noncompliance among aircraft operators was primarily limited to small business jet operators, nonscheduled carriers, and third-country operators that failed to respond to competent authorities.

SAF distribution reached 121 Airports across all 27 Member States, representing 79 percent of all Union airports. Uptake was heavily concentrated at major European hubs. Amsterdam Airport Schiphol (AMS) accounted for 29 percent of the tracked SAF supply, followed by Frankfurt Airport (FRA) at 8 percent and Paris Charles de Gaulle Airport (CDG) at 7 percent.

Supply chain dynamics and feedstock dependencies

While the headline blending figures demonstrate regulatory success, the technical report reveals a structural reliance on imported raw materials. Although 86 percent of the SAF supplied at EU airports was refined domestically within the European Union, 85 percent of the underlying feedstocks originated from outside the bloc.

The primary feedstock utilized was Used Cooking Oil (UCO) processed via the Hydroprocessed Esters and Fatty Acids (HEFA) pathway. Of the imported feedstocks, 61 percent originated from China, with additional volumes sourced from Malaysia and Indonesia. On the refining side, Neste’s Rotterdam facility alone produced 33 percent of all European SAF in 2025.

AirPro News analysis

The successful implementation of the 2 percent mandate in 2025 proves that the logistical framework for SAF distribution at major European hubs is functional. However, the heavy reliance on Asian Used Cooking Oil presents a long-term vulnerability for European aviation. As the ReFuelEU mandate scales to 6 percent in 2030, the Regulations will also introduce sub-mandates for synthetic aviation fuels (e-fuels). With approximately 50 synthetic fuel projects awaiting final investment decisions and no large-scale e-fuel facilities currently operational in Europe, we anticipate significant capital mobilization will be required over the next 36 months to prevent future supply bottlenecks and reduce dependency on imported biomass.

Montana Renewables Cuts SAF Expansion Cost to $137M

Calumet’s Montana Renewables targets 200M gallons of SAF annually by 2028 for $137M, down from a $1.2B plan.

Published

on

Calumet, Inc. and its subsidiary Montana Renewables, LLC announced a revised expansion plan on September 1, 2026, that will scale SAF production to 200 million gallons annually by 2028 for a fraction of the originally projected cost.

By repurposing existing refining equipment at the Great Falls, Montana facility, the company expects to complete the MaxSAF project with only $137 million in remaining capital. This abandons a previous $1.2 billion megaproject design. The pivot eliminates the need for third-party equity and minimizes debt while accelerating domestic sustainable aviation fuel (SAF) capacity.

Capital efficiency and Department of Energy funding

The original Phase 2 plan contemplated $1.2 billion in capital expenditure. The revised strategy captures 70 percent of the expected benefit for 15 percent of the cost. The financial restructuring involves an amended Loan Guarantee Agreement (LGA) with the U.S. Department of Energy (DOE).

The original LGA was executed in January 2025, with a $782 million first tranche funded in February 2025 to recapitalize Montana Renewables, LLC (MRL). Under the amended agreement, the company will make a final draw of $34 million. This is significantly lower than the original $658 million Phase 2 DOE funding limit.

Calumet CEO Todd Borgmann stated the Office of Energy Dominance Financing (EDF) supported the adjustment to the loan agreement.

“Our amended agreement with the DOE facilitates innovative technology and domestic energy security at a fraction of the original cost. EDF’s willingness to right-size the LGA reflects its ongoing support for Montana’s largest agricultural investment. We look forward to our continued collaboration with the DOE on the success of this project,” Borgmann said.

Borgmann credited the company’s engineering and operational teams for developing a project that maximizes output while drastically reducing the required capital investment.

Production timeline and capacity milestones

The Great Falls facility currently operates at a 60 million gallon SAF run-rate following a spring 2026 constraint removal. A scheduled turnaround in the fourth quarter of 2026 will tie in repurposed equipment from the adjacent Calumet Montana Refining facility.

Following the fourth-quarter integration, the company expects to exceed an 80 million gallon SAF run-rate by December 31, 2026. Production is projected to surpass 120 million gallons by spring 2027 and reach the 200 million gallon target by December 31, 2028.

Total renewable product sales, including renewable diesel and renewable gasoline, are targeted at 17,000 barrels per day by year-end 2028. This represents a 40 percent expansion. The expanded facility will consume 2 billion pounds of ranch- and farm-originated feedstocks annually.

AirPro News analysis

The revised MaxSAF expansion highlights a strategic shift in how producers approach SAF scaling. As noted by Aviation Week on September 2, 2026, the plan allows the largest US producer of SAF to more than triple its production capacity for barely 10 percent of the originally planned investment.

During Calumet’s second-quarter 2026 earnings call on August 7, 2026, the company confirmed that Montana Renewables completed performance testing of the newly installed MaxSAF catalyst, which met or exceeded expectations. By leveraging existing fossil-fuel infrastructure rather than pursuing multi-billion-dollar greenfield projects, producers can bring SAF to market faster and with significantly lower financial risk. This capital-efficient model may set a precedent for other refiners looking to enter or expand in the renewable fuels sector without diluting equity or taking on unsustainable debt.
