Airbus, Rolls-Royce and Siemens are to develop hybrid electric engine plane technology as part of a push towards cleaner aviation.
The E-Fan X programme will first put an electric engine with three jet engines on a BAe 146 aircraft.
The firms want to fly a demonstrator version of the plane by 2020, with a commercial application by 2025.
Firms are racing to develop electric engines for planes after pressure from the EU to cut aviation pollution.
