ZeroAvia Builds Patent Portfolio for Hydrogen-electric Airliners
Start-up says it now holds 45 patents around its plans for hydrogen-electric powertrains
ATR72 regional airliner could be fitted with ZeroAvia's hydrogen-electric propulsion system.
The ATR72 is one of several regional airliners ZeroAvia intends to convert with its hydrogen-electric propulsion system.

ZeroAvia says it now holds 45 patents covering technology for the hydrogen-electric powertrains it intends to use to convert existing regional airliners. On July 17, the company reported it has more than 200 patent applications being processed by authorities in the U.S. and Europe.

One of the more prominent patents is No. 12,341,225 issued by the U.S. Patent and Trademark Office. This covered an integrated 2-megawatt-class hydrogen-electric ZA2000 engine that ZeroAvia is working to install on ATR and Dash 8 aircraft, seating between 40 and 80 passengers.
