With sustainability finally coming around to be the centre stage of aviation discussions, it is no surprise that airlines and aircraft OEM are now taking it upon themselves to own the sustainability agenda. While aircraft have become more ‘sustainable’ over time, with lesser fuel consumption, the next generation of aircraft is expected to work on cleaner fuels altogether (SAF) or alternate sources of power, such as hydrogen or electricity.

In September 2020, Airbus was the first to step up and reveal their bets on the future with the proposed zero-emission commercial aircraft concept called “Zero-E”, exploring hydrogen as a future fuel. They doubled down on it in September 2021, with a full two days of panel discussions to further their vision. Airbus is confident of bringing these concepts to life commercially by 2035. Boeing so far is betting the house on developments in the space of Sustainable Aviation Fuel (SAF) to take the mantle of cleaner aviation.

Now, Brazilian aircraft manufacturer, Embraer, has entered the space. In a webcast hosted a few hours ago, Embraer has unveiled four aircraft concepts that intend to use clean energy for its propulsion. These are all concepts at the moment, and again, have to be explored further to make viable aircraft that could enter into service after 2030.

Introducing Embraer’s Energia aircraft

Embraer has named their new aircraft family Energia and focuses on the regional aviation segment with this new family of aircraft. The Energia concept family would feature between 9 and 50 seats. Since these are all concept aircraft, there will be a lot of work before they take to the skies, but we have to be excited for them for now.

We see our role as a developer of novel technologies to help the industry achieve its sustainability targets. There’s no easy or single solution in getting to net zero. New technologies and their supporting infrastructure will come online over time. We’re working right now to refine the first airplane concepts, the ones that can start reducing emissions sooner rather than later. Small aircraft are ideal on which to test and prove new propulsion technologies so that they can be scaled up to larger aircraft. That’s why our Energia family is such an important platform.

The Energia Aircraft Concepts

Energia Electric (E9-HE)                      

Energia Electric intends to explore full-electric propulsion with aft contra-rotating propellers. The aircraft would be a 9-seater and offer zero Carbon dioxide emissions. Embraer expects the technology readiness for this aircraft to be in 2035.   

We will see a big transformation in our industry towards a more sustainable aviation. With 50 years’ experience in developing, certifying and supporting regional aircraft, Embraer is in a unique position to make viable the introduction of new disruptive green technologies.

Bottomline

Embraer is the second major OEM to enter sustainable aviation discussion. They have revealed their Energia aircraft concepts, which are focused on exploring electric and hydrogen propulsion. Early days, so we have to see how far Embraer gets with these technologies. For the benefit of the environment, though, I hope they do. We will find out in roughly a decade anyways.

What do you think of Embraer’s new sustainable aircraft concepts?
