United invests in zero-emission engines for regional aircraft
Through a new equity stake in ZeroAvia, a leading company focused on hydrogen-electric aviation solutions, United expects to buy up to 100 of the company's new zero-emission, 100% hydrogen-electric engines (ZA2000-RJ). The engine could be retrofit to existing United Express aircraft as early as 2028.
"Hydrogen-electric engines are one of the most promising paths to zero-emission air travel for smaller aircraft, and this investment will keep United out in front on this important emerging technology," said Scott Kirby, CEO of United. "United continues to look for opportunities to not only advance our own sustainability initiatives but also identify and help technologies and solutions that the entire industry can adopt."
Hydrogen-electric engines use electricity created by a chemical reaction in a fuel cell to power an electric motor instead of burning fossil fuel. Because no fuel is burned, there are no climate-harming emissions or carbon released into the atmosphere when the engines are operated.
New power sources
The ZA2000-RJ is expected to be used in pairs as a new power source for existing regional aircraft. Under the agreement with United Airlines Ventures, United will pursue a conditional purchase agreement for 50 ZeroAvia ZA2000-RJ engines, with an option for 50 more, enough for up to 50 twin-engine aircraft which would be operated by United Express partners once they are fully developed and certified by regulators as soon as 2028.
"This support by United, alongside our other forward-thinking partners, demonstrates the importance of hydrogen-electric propulsion in the future of sustainable flight," said Val Miftakhov, founder and CEO and of ZeroAvia. "The United Express routes powered by hydrogen-electric aircraft will be enabling large numbers of passengers to take zero-emission flights well within this decade."
ZeroAvia is accelerating the development of its ZA2000 engine and will soon begin ground tests of its ZA600 in a 19-seat aircraft, with the aim of entering commercial service with this smaller engine by 2024.
