Air travel is an important supplement to other means of regional transportation and in some regions the only viable solution. However, the regional transport market is highly competitive, and air travel must demonstrate that it can compete with hi-speed trains, cars or coaches. One major issue is the perception of the high CO2 and greenhouse gas (GHG) emissions by planes for these short journeys. Hybridization of the propulsion system enables combining the technical components benefits, thereby achieving an overall efficiency improvement. It is a concept well understood by the general public, due to the hybridization of automobiles, and can bring a real impact on the reduction of GHG emissions.

While enabling rather than limiting new sources of energy in aviation, an ambitious path to reduction of greenhouse gases and the pathway to a cleaner and greener aviation for regional flights is built upon three pillars:
•    Electric hybridization
•    An ultra-efficient turboprop thermal engine
•    100% SAF compatibility
