ZeroAvia secures funding to ‘power the next phase for the company’
Hydrogen-electric propulsion startup ZeroAvia has secured funding to ‘power the next phase for the company’ after investors provided financial support for the next two years of development.
The British-US technology firm announced in May 2025, that it was working towards raising $150 million in Series D funding to continue progression towards certification of its hydrogen-electric engines.
On December 22, 2025, ZeroAvia said that the latest round of investment had been led by Barclays Climate Ventures, Breakthrough Energy Ventures, Ecosystem Integrity Fund, Horizons Ventures, Summa Equity, and AP Ventures, with participation from the National Wealth Fund and the Scottish National Investment Bank.
“With additional investment secured, ZeroAvia has extended its cash runway for the next two years and will continue to fully industrialize its hydrogen power and propulsion technology for the aviation and defense markets,” said a spokesperson for ZeroAvia.
In September 2025, FlightGlobal reported that a delay to further funding could affect ongoing operations after the first quarter of 2026.
ZeroAviaThe support shown in this investment to power the next phase for the company is a great vote of confidence in the company’s technology and roadmap. With this latest financing we are able to progress at pace on the most immediate market opportunities – such as the SuperStack Flex – which will enable us to derisk later stages of our roadmap,” said Val Miftakhov, Founder and CEO, ZeroAvia.
As well as developing the full hydrogen-electric powertrains ZA600 and ZA2000, ZeroAvia is already supplying its SuperStack Flex modular fuel cell power generation system to the defense sector.
ZeroAvia is also in active customer discussions with eVTOL and fixed-wing commercial players in relation to deploying the system.
The SuperStack Flex is a core module of ZeroAvia’s ZA600, which is designed to power 10-20 seat commercial aircraft.
The developer has over 30 patents granted and more than 100 pending in hydrogen fuel cell systems, power electronics, and electric motor technology for aircraft.
