Otto Aviation, which is developing a six-seat, piston-powered private aircraft, known as the Celera 500L, on Tuesday unveiled plans to create a zero-emissions version of the high-efficiency aircraft during  Green Innovations webcast organized by the International Civil Aviation Organization. The U.S. company expects the initial conventionally-powered version of the aircraft which features a curiously portly, but laminar-flow friendly fuselage to enter service in 2025.

“We’re pleased to announce the development of a zero-emissions version of the aircraft by 2027, using either battery-electric or Hydrogen power,” said David Bogue, the airframer’s chief technology officer, adding it is designing the single-engine pusher, which is powered by a 550-hp RED A03 diesel engine, with the ability be retrofit to a zero-emissions powertrain. “We’re designing the baseline aircraft to be compatible with either until the combination of performance and infrastructure clarifies which is preferable.”
