ZeroAvia secures a $3.25 million grant from the California Energy Commission for the development of a groundbreaking mobile liquid hydrogen refueling truck. Positioned for heavy-duty applications, this innovation aims to revolutionize aviation and maritime industries. With operations launching at Livermore Municipal Airport, ZeroAvia's project accelerates the viability of liquid hydrogen-fueled aircraft, emphasizing energy efficiency, cost-effectiveness, and rapid refueling.


In a significant stride towards sustainable aviation, ZeroAvia has been awarded a $3.25 million grant by the California Energy Commission (CEC) to pioneer the development of a unique mobile liquid hydrogen (LH2) refueling truck. This trailblazing project targets heavy-duty applications, particularly in the realms of aviation and maritime, marking a crucial step towards zero-emission transport solutions.

Commencing its operations at Livermore Municipal Airport, ZeroAvia is set to embark on the design, construction, and demonstration of a 10,000-liter mobile LH2 refueler. The ambitious goal is to achieve refueling times comparable to traditional jet fuel, ensuring hydrogen-powered aircraft meet stringent turnaround windows, especially in regional transport scenarios.

Beyond the quest for speed, the LH2 refueler is engineered to enhance energy efficiency in LH2 applications. Notably, it aims to minimize hydrogen boil-off to an impressive less than 0.1% per day, contributing to the sustainability of hydrogen-powered aviation.

ZeroAvia's broader vision revolves around utilizing hydrogen fuel cell propulsion to address the environmental impact of aviation. By 2025, the company plans to support passenger and cargo flights with its first hydrogen-electric engines, specifically the ZA600 model designed for 9-19 seat aircraft utilizing gaseous hydrogen storage.

To extend the application of hydrogen engines to larger commercial aircraft and enable longer ranges, ZeroAvia is delving into cryogenic liquid hydrogen. The development of the larger ZA2000 engine family, with successful high-power ground tests conducted earlier, is a pivotal step. Collaborative projects, such as the Dash-8-400 76-seat aircraft with Alaska Airlines, underscore the company's commitment to larger aircraft, targeting a 2027 launch with up to 1 ton of LH2 storage onboard for a 700 nautical mile range.

The CEC-funded initiative not only propels advancements in liquid hydrogen-fueled aircraft but also holds promise for broader applications in road freight and maritime. Beyond the environmental benefits, the project aligns with California's commitment to reducing greenhouse gas emissions, presenting new economic opportunities.

Val Miftakhov, Founder & CEO of ZeroAvia, emphasizes the urgency of advancing clean engine technology in response to the climate emergency. The mobile LH2 refueler project stands as a crucial component in optimizing refueling technologies, essential for the widespread adoption of clean and sustainable transportation solutions.

Jonah Steinbuck, Director of the Energy Research and Development Division at the CEC, highlights the project's potential to reduce greenhouse gas emissions in the challenging aviation sector and across the broader transport segment. The technology's promise extends beyond environmental benefits, holding the potential to create economic opportunities in California and beyond.

Pete Sandhu, CEO of Five Rivers Aviation, applauds the partnership with ZeroAvia, acknowledging the pioneering research and development that aligns with Livermore's capabilities as a hub for clean and quiet aviation technologies. The collaboration positions airports as multi-modal hubs for hydrogen-fueled transport, fostering compatibility with surrounding communities.

As ZeroAvia expands its operations to Livermore, the company adds another milestone to its journey, leveraging California's forward-thinking approach to renewable energy infrastructure and green transportation. With a strong focus on certifying its first zero-emission engines, ZeroAvia is poised to make California a potential hub for the adoption of hydrogen-electric flights.


ZeroAvia's venture into developing a mobile liquid hydrogen refueling truck signifies a crucial leap towards sustainable aviation. The CEC-funded project not only accelerates the adoption of liquid hydrogen-fueled aircraft but also holds the potential to revolutionize transportation beyond aviation. ZeroAvia's commitment to advancing clean engine technology aligns with the imperative of addressing the climate emergency, setting the stage for a cleaner and more sustainable future in heavy-duty transportation.
