ZeroAvia has announced that they have been granted nine new patents key to the development of large hydrogen aviation, expanding the company’s IP portfolio, with 45 patents granted to date.
On Thursday (July 17, 2025), ZeroAvia announced that they have been awarded nine new patents this year so far, with many critical to the company’s roadmap for scaling hydrogen-electric engines for large regional aircraft. To date, the company has been granted a total of 45 patents related to hydrogen and electric aviation systems, with nearly 250 applications still being processed by the United States Patent and Trademark Office (USPTO).
In Thursday’s announcement, ZeroAvia’s Founder and CEO, Val Miftakhov, said
“Recent patents filed and granted around hydrogen aviation give a window into an accelerating field of innovation. As we see the large airframe manufacturers beginning to compete on technologies for hydrogen aircraft, there is a big opportunity for companies pioneering hydrogen propulsion systems. These are the inventions that will deliver truly clean, more affordable and highly efficient commercial air travel.”
USPTO patent number 12,341,225 covers an integrated hydrogen-electric engine and is key to the development of a modular multi-MW hydrogen-electric engine for ATR and Dash 8 families of aircraft. The design concept relates to ZeroAvia’s ZA2000 engine for 40-80 seat regional turboprops and jets, with advanced and novel integration concepts creating a tightly packaged, power-dense zero-emission aircraft engine. UK patent office GB2614450 covers novel coatings for aluminum bipolar plates for high temperature PEM (HTPEM) fuel cell systems, allowing the higher temperature operation with lightweight metals, while overcoming material degradation challenges.
Other patents cover critical innovations in cryogenic management systems, thermal management for fuel cell systems, and fuel cell catalysts using platinum nanoparticles. One relates to a refueling system for hydrogen fuel cell-powered aircraft that enables both efficient refueling, and employs a thermoelectric generator to leverage the heat from the refueling process to provide electricity for other aircraft systems. ZeroAvia’s patent portfolio now includes coverage across all key subsystems of the engine and aspects of aircraft integration. The company now boasts one of the most advanced IP portfolios in hydrogen-electric aviation powertrain technology.
ZeroAvia is a leader in the transition to a clean future of aviation by developing electric propulsion technologies for aviation, which will deliver lower costs and emissions, reduced noise, energy independence, and increased connectivity. The company is developing hydrogen-electric fuel cell-powered engines for existing commercial aircraft, and also supplying hydrogen and electric propulsion component technologies for new electric air transport applications. ZeroAvia has submitted their first full engine for up to 20 seat airplanes for certification, and is working on a larger powertrain for 40–80 seat aircraft, with significant flight test and regulatory milestones achieved with the U.S. FAA and UK CAA.
