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.

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.

Lufthansa Airlines (LH) has secured revalidation under the European Union’s Eco-Management and Audit Scheme (EMAS) for the 2025 reporting year, while Lufthansa City Airlines and Lufthansa Aviation GmbH achieved the environmental certification for the first time.

In a press release issued on August 6, 2026, the Lufthansa Group announced the certifications, confirming the operators are implementing measurable environmental measures across flight operations and ground processes. The EMAS system is a voluntary European Union (EU) instrument that fully incorporates the requirements of the ISO 14001 international environmental management standard.

Operational efficiency and fuel savings

The validation process evaluated the airlines’ progress in reducing their environmental footprint. According to the company, the 2026 Environmental Statement emphasizes operational fuel efficiency. The report details how specific measures implemented from the flight planning stage through to landing result in measurable kerosene savings.

Broader climate technology initiatives

The EMAS validations follow several recent environmental technology initiatives across the Lufthansa Group. On July 30, 2026, the company announced it is testing a next-generation “AeroSHARK” surface film on a Lufthansa City Airlines Airbus aircraft. The film is designed to reduce aerodynamic drag and lower fuel consumption.

Earlier in the year, on May 20, 2026, the group expanded its climate protection portfolio to include Direct Air Carbon Capture and Storage (DACCS) technologies. This initiative involves partnerships with aerospace manufacturer Airbus and climate technology company Climeworks to filter carbon dioxide directly from ambient air.

The addition of Lufthansa City Airlines to the EMAS registry indicates that the Lufthansa Group is prioritizing environmental compliance for its newer subsidiaries from their inception. Because EMAS requires public environmental reporting and continuous performance improvement beyond standard ISO 14001 compliance, maintaining this validation requires sustained capital investment in fuel-saving technologies like the AeroSHARK film and DACCS partnerships. We expect European operators to increasingly leverage voluntary frameworks like EMAS to demonstrate regulatory readiness ahead of stricter EU aviation emissions mandates.

Indian urban air mobility startup Sarla Aviation has adopted the Siemens Xcelerator software portfolio to accelerate the design and certification of its next-generation electric vertical take-off and landing (eVTOL) aircraft.

Announced in a press release on August 5, 2026, the partnership integrates Siemens Digital Industries Software into Sarla Aviation’s development pipeline. The integration aims to streamline the complex engineering and regulatory validation processes required for aerospace Certification, supporting the startup’s target of launching commercial air taxi operations in Bengaluru by 2028.

Digital integration for aerospace certification

Sarla Aviation will utilize multiple components of the Siemens Xcelerator portfolio, including Designcenter, Simcenter, Capital, Polarion, and Teamcenter. By implementing a comprehensive digital thread, the manufacturer intends to reduce physical design iterations through early-stage simulation and improve engineering collaboration across its teams.

A primary driver for the software adoption is the stringent regulatory environment for new aircraft. The Siemens toolset is specifically designed to support complex traceability, verification, and validation processes, including compliance with the DO-178C standard for airborne software certification.

“By adopting a comprehensive digital thread using the Siemens Xcelerator portfolio, companies like Sarla Aviation are able to help accelerate development, improve collaboration and support certification processes for next-generation aircraft,” said Mathew Thomas, Vice President and Managing Director for India at Siemens Digital Industries Software.

Advancing India’s urban air mobility ecosystem

The software partnership follows a series of technical and financial milestones for the Bengaluru-based startup. In July 2026, Sarla Aviation successfully completed flight tests of Sylla, its electric eVTOL technology demonstrator. The company reported that the testing validated integrated aircraft systems and controlled hover capabilities for what it describes as India’s largest and heaviest eVTOL demonstrator.

Financial backing for the development program expanded earlier in the year. In April 2026, IndiGo Ventures, the corporate venture arm of Indian airline IndiGo, made a strategic ₹100 million (approximately US$1.2 million) investment in Sarla Aviation. While IndiGo noted the investment does not signal a near-term entry into eVTOL operations, it positions the airline to explore India’s future air mobility ecosystem.

Sarla Aviation Co-Founder & CTO Rakesh Gaonkar stated that working with Siemens supports the company’s ability to innovate faster. He noted the ambition is to make electric air mobility accessible at scale while maintaining high standards of safety and performance.
