Embraer has announced plans to broaden its Energia future aircraft study to include larger aircraft, up to 50 seaters, driven by feedback from airline partners. The study, which initially focused on smaller aircraft, will now explore concepts for larger planes with three propulsion options: hybrid-electric, pure hydrogen, and dual-fuel hydrogen/gas turbines. The company anticipates that the hybrid-electric option will have lower CO2 emissions and expects the pure hydrogen concept to be viable by 2035. However, the dual-fuel concept, allowing the aircraft to run on both hydrogen and conventional jet fuel, presents the most significant development challenge and is not expected to enter service until at least 2038. Partnering with airlines, including Finnair and others, is crucial for understanding how these aircraft will be utilized in real operations. The collaboration with airlines will provide insights to inform the development of these concepts, ensuring they meet the industry's needs and demands.
