Embraer has been periodically presenting updates on research into its “Energia” family of sustainable aircraft, and at Farnborough it was no different.
Among the announcements by the Brazilian company is the inclusion of Hydrogen Gas Turbine/Dual Fuel (GT/DF) propulsion technology.
The concepts previously studied are the hybrid-electric, with state-of-the-art thermal engines and a small electric motor used to maximize efficiency during takeoff and taxiing, and the fuel cell, which eliminates pollutant emissions.

Embraer is also evaluating new technologies in the design of cleaner fuselages and wings without the so-called “propwash”, which consists of installing propellers on the tail of the aircraft. In addition, new possibilities for structural and systems integration projects are being studied.
Regarding the new type of propulsion, Embraer stated that it consists of the use of liquid hydrogen (cryogenic) and kerosene or SAF to extend range and reserve.
The most relevant new feature, however, is the increase in the passenger capacity of Energia aircraft, which can now reach 50 seats.
According to the manufacturer, this was a conclusion of the Energia Advisory Group, which periodically brings together a group of partners that includes airlines, lessors, suppliers and other aviation experts.
An environmentally friendly aircraft with 50 seats is in line with other projects of this type and that enhance its application on denser routes, in addition to making it an alternative to turboprops such as the ATR.
There is still no clear forecast for the development of the Energia family, but Embraer estimates that this could occur by 2045.
