ZeroAvia has used Dash 8 aircraft as a testbed for the ZA2000 hydrogen-electric propulsion system it intends to use to convert 70-seat CRJ700 regional jets for customers including American Airlines.

American Airlines has agreed to purchase 100 of ZeroAvia’s hydrogen-electric engines to convert 70-seat Bombardier CRJ700 regional jets. The conditional sales agreement was announced by the companies on July 2.

ZeroAvia, which is developing the 2-megawatt ZA2000 powertrain for aircraft seating up to 90 passengers, is also aiming to introduce the 600-kilowatt ZA600 engines for 20-seat regional aircraft. The company, which in April opened a manufacturing site for components near Seattle, has said the first ZA600 units will be installed under supplemental type certificates (STC) in 2025, with the larger units to follow in 2027.
