Published

on

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.

American Airlines Completes First eSAF Commercial Flight

American Airlines and Infinium completed the first commercial passenger flight on electro sustainable aviation fuel on August 6, 2026.

Published

on

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.

AirPro News analysis

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.
