ZeroAvia Secures Financing for Hydrogen Power Solutions in Aviation and Defense

ZeroAvia Secures New Financing Round

On December 22, 2025, ZeroAvia, the progressive leader in hydrogen-electric propulsion technologies, announced the completion of a significant round of financing. This funding round was notably led by Barclays Climate Ventures and supported by various investors, including Breakthrough Energy Ventures, Ecosystem Integrity Fund, Horizons Ventures, Summa Equity, AP Ventures, the National Wealth Fund, and the Scottish National Investment Bank.

This influx of capital is set to extend ZeroAvia's operational runway for the upcoming two years, enabling the company to advance its innovative hydrogen power and propulsion technologies specifically for the aviation and defense sectors. ZeroAvia has already established a foothold in the defense industry by supplying its versatile SuperStack Flex modular fuel cell power generation system, essential for evolving the capabilities of unmanned aerial vehicles (UAVs).

The SuperStack Flex is a game changer in the power generation landscape, as it offers both electric propulsion and superior electrical power generation on board, boasting greater power density than traditional battery systems. It aims to deliver numerous advantages, such as lower thermal and noise signatures, reduced maintenance costs, increased reliability, and, most importantly, zero emissions. Moreover, it enhances the operational endurance of aircraft.

A noteworthy milestone for ZeroAvia occurred in November when they received Design Organisation Approval from the UK Civil Aviation Authority (CAA). This enables the company to prepare for the regulatory approval of its pioneering fuel cell systems destined for aviation applications.

In addition to serving as a stand-alone power solution across diverse defense and civil sectors, the SuperStack Flex is a central element of ZeroAvia's ambitious ZA600 hydrogen-electric powertrain, intended for commercial aircraft accommodating 10 to 20 passengers. Following extensive flight tests on a prototype, ZeroAvia has secured hundreds of engine orders from airline customers, including an inaugural customer. The company is also positioned to roll out 15 aircraft in Norway as part of its near-term deployment strategy.

Val Miftakhov, the Founder and CEO of ZeroAvia, expressed excitement about the investment, stating that this endorsement enhances confidence in the company's technology and future roadmap. He emphasized that this recent financial backing would propel the company forward in tapping immediate market opportunities, particularly with the SuperStack Flex, which is crucial for mitigating risks associated with future developments.

ZeroAvia is at the forefront of transforming aviation by pioneering hydrogen-electric propulsion technologies designed to offer lower costs, diminished emissions, elevated energy independence, and improved connectivity. The company is not only working on the hydrogen-electric engines aimed at existing aircraft segments but is also supplying essential components for innovative electric air transport applications. Their focus includes battery hybrid engines and UAV technologies such as eVTOL designs and hybrid rotorcraft.

Moreover, ambitious plans are underway as ZeroAvia prepares to submit its first full hydrogen-electric engine for certification, which will cater to aircraft designed for up to 20 seats. Bigger ambitions lie ahead, including plans for powertrains suitable for 40 to 80-seat aircraft, further solidifying ZeroAvia's commitment to leading the evolution in clean aviation.
