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.

Industry Context and Market Demand

AirPro News analysis

At AirPro News, we observe that the pilot training market serves as the ideal launchpad for the broader adoption of electric aviation. Training flights typically last around one hour, which aligns perfectly with the current energy density limitations of modern battery technology. Furthermore, flight schools operate on notoriously tight margins. Transitioning from internal combustion engines, which require frequent, expensive maintenance and costly aviation fuel, to electric motors drastically lowers the total cost of ownership.

However, the most significant barrier in this sector remains the certification hurdle. The aviation industry is highly regulated, and while many startups can successfully fly experimental electric planes, engineering a battery system that regulators like EASA and the FAA will approve is the primary bottleneck. Regulators require strict adherence to safety standards, particularly regarding thermal runaway containment and system redundancy. H55’s delivery of “conforming certifiable” modules is a massive differentiator, indicating that the company is successfully navigating this complex regulatory gauntlet and moving the industry closer to standardized electric flight.

This article is based on an official press release from Doroni Aerospace.

Doroni Aerospace has officially unveiled the showroom engineering model of its H1-X personal electric vertical takeoff and landing (eVTOL) aircraft. The reveal took place during the company’s “Soul of the Sky” event on March 26, 2026, at its headquarters in Dania Beach, Florida, where guests were given an exclusive first look at the hardware and its accompanying software ecosystem.

According to the company’s official press release, this unveiling represents a critical milestone in its mission to bring personal aerial mobility to the consumer market. Alongside the physical aircraft, Doroni introduced SOUL AI™, a proprietary Digital Co-Pilot Operating System designed to make personal flight highly intuitive for everyday users.

With initial deliveries targeted for 2028, the H1-X is engineered to fit inside a standard two-car garage and operate without the need for specialized aviation infrastructure. Local officials also recognized the milestone, with Dania Beach Mayor Joyce L. Davis issuing a proclamation designating March 26 as “Doroni Aerospace Day.”

The H1-X eVTOL: Technical Specifications

Design and Performance

Based on company specifications released during the event, the H1-X is a two-seater personal aircraft that prioritizes efficiency and ease of use. The eVTOL boasts an estimated range of up to 100 miles on a single charge. It is designed to reach a cruise speed of 95 mph and a top speed of 120 mph.

To support daily commuting, the aircraft utilizes swappable battery packs that are compatible with standard electric vehicle (EV) chargers, allowing for a full charge in 20 to 25 minutes. The vehicle has an empty weight of 1,850 lbs and supports a maximum payload capacity of 500 lbs. Because it is capable of vertical takeoff and landing, the H1-X requires no runway and can be operated directly from a standard residential driveway.

Safety and Propulsion

The H1-X features a patented tandem wing configuration paired with an electric ducted fan propulsion system. Lift is generated by eight vertical electric motors, while forward flight is powered by two rear-mounted pusher propellers.

Safety remains a focal point of the design. The ducted fans enclose the spinning blades, a feature the company notes will significantly reduce noise and protect bystanders on the ground. Additional safety measures include redundant flight control systems, advanced anti-collision sensors, and a built-in whole-aircraft ballistic parachute.

Introducing SOUL AI™ Digital Co-Pilot

Lowering the Barrier to Entry

A major highlight of the “Soul of the Sky” event was the introduction of SOUL AI™, Doroni’s proprietary onboard operating system. The software acts as an intelligent human-machine interface (HMI) designed to lower the barrier to entry for new pilots.

According to the company, the system is built on three core pillars: Protection, Guidance, and Experience. It functions as a “360-degree guardian” using environmental sensors, provides real-time navigation and weather updates via secured connections, and replaces the traditional aviation cockpit with a modern, intuitive interface.

Doroni Aerospace CEO and Founder Doron Merdinger emphasized that the technology is meant to seamlessly integrate with the user. Speaking on the software’s design philosophy, Merdinger stated:

“We aim to make this vehicle feel less like a machine you have to manage and more like a natural extension of you.”

Certification and Market Strategy

Regulatory Pathway

Founded in 2016, Doroni Aerospace handles its engineering, testing, and production in-house at its South Florida facilities. In December 2023, the company achieved a significant regulatory milestone by receiving a Special Airworthiness Certification from the FAA, permitting manned flight testing in U.S. airspace.

Moving forward, Doroni plans to certify the H1-X as a Light Sport Aircraft (LSA) under the FAA’s proposed Modernization of Special Airworthiness Certification (MOSAIC) rules. This pathway would make the aircraft accessible to consumers with standard pilot training. As of mid-2025, the company reported securing over 500 pre-orders for the H1-X.

AirPro News analysis

We note that Doroni’s strict focus on the direct-to-consumer market differentiates it significantly from the broader Advanced Air Mobility (AAM) industry. While major players like Joby Aviation and Archer Aviation are currently dominating the sector by developing commercial “air taxi” services, Doroni is treating the eVTOL more like a personal luxury EV. By designing an aircraft that charges on standard EV infrastructure and fits in a residential garage, the company effectively bypasses the need for specialized “vertiports”, currently a major logistical and financial hurdle for the commercial air taxi industry. Furthermore, the enclosed ducted fan design, while historically complex to engineer, is a vital component for neighborhood safety and noise reduction, making the concept of driveway takeoffs a realistic possibility.

Frequently Asked Questions (FAQ)

When will the Doroni H1-X be available to consumers?

According to the company’s current timeline, initial deliveries of the H1-X are slated for 2028.

Do I need a commercial pilot’s license to fly the H1-X?

No. Doroni Aerospace plans to certify the H1-X as a Light Sport Aircraft (LSA) under the FAA’s proposed MOSAIC rules, which would allow consumers to operate the vehicle with standard pilot training rather than a commercial license.
