Embraer has unveiled significant advancements in its sustainable aircraft program, Energia, at the Farnborough Airshow. Initially focused on 30-seater aircraft, the project now includes 50-seater models. Expanding beyond Hybrid Electric and Fuel Cell technologies, Embraer has introduced Hydrogen Gas Turbine/Dual Fuel (GT/DF) approaches.
The catalyst behind these innovations is Embraer’s Energia Advisory Group, comprised of industry leaders such as airlines, lessors, and suppliers. This group advises on various aspects, including new propulsion technologies, advanced aerodynamics, structural design, systems integration, noise reduction, and passenger comfort.
Arjan Meijer, President & CEO of Embraer’s Commercial Aviation division, emphasized the project’s evolution in response to technological advancements, infrastructure readiness, and regulatory changes. He anticipates the potential deployment of Energia concepts within the next decade. Meijer acknowledged the advisory group’s contributions, underscoring their insistence on feasibility across technical, economic, commercial, and infrastructure dimensions.
Key attributes of the new Energia concepts include advanced airframe design optimizing aerodynamics and structural integrity, alongside enhanced cabin comfort and reduced noise levels facilitated by rear propulsion. Hybrid-electric concepts feature a parallel hybrid electric powerplant integrating thermal engines with small electric engines for improved efficiency during takeoff and idle phases. Propulsion electrification is synchronized with more electric aircraft systems, incorporating a cost-efficient battery.
