Green Taxi Aerospace will fit electric motors to airliner landing gear and charge these with power from APUs.

Green Taxi Aerospace says it expects to secure the first supplemental type certificates in 2027 for hybrid-electric technology that reduces emissions from airliners taxiing to and from airport gates. At the Future Aero Festival in Amsterdam earlier this month, the U.S. start-up’s CEO and founder David Valaert said it is now working with Delta Airlines and Embraer to fit the system to E175 regional jets.

The Green Taxi system uses power from APUs to charge electric motors fitted in the aircraft’s main landing gear. The company says that by avoiding the need to taxi with power from the main engines, this approach can reduce fuel burn for short-haul flights by between 5% and 20%.
