While airlines chase sustainable fuels and regulators talk carbon taxes, a young startup is quietly betting on something bolder: a 100% electric, regional aircraft that claims to use eleven times less energy than today’s planes.
A radical answer to regional flight emissions
The project comes from Eenuee, a start-up based near Lyon, founded in 2019 with a clear ambition: electrify short-haul regional aviation. Its first baby, called Gen-ee, is designed to carry 19 passengers up to 500 kilometres on a single charge.
That range targets the kind of short hops that still rely heavily on small turboprops: links between mid-sized cities, islands, mountain regions and remote areas where rail is slow or simply does not exist.
Gen-ee aims to offer regional flights with up to 11 times less energy consumption than conventional aircraft of similar capacity.
Crucially, the aircraft is being designed to operate from existing small airports, with no need for new runways or heavy infrastructure. That makes it attractive for local authorities with tight budgets, especially in regions where roads and rail lines are hard to build or upgrade.
Beyond batteries: a blended wing body
Gen-ee is not just “a normal plane with batteries”. Eenuee has opted for a blended wing body (BWB) design with what engineers call a “lifting fuselage”.
Seen from above, the aircraft looks like a wide flying wing rather than the classic tube-with-wings layout. Seen from the side, the fuselage itself has the shape of an airfoil, contributing lift alongside the wings.
Why the shape matters so much
This unusual geometry is central to the energy claims. Eenuee’s engineers say the BWB configuration offers a dramatic reduction in drag compared with conventional regional aircraft.
They report an aerodynamic efficiency, or lift-to-drag ratio, of about 25. For a 19-seater operating under EASA’s CS-23 category, that would put it well above typical designs in its class.
The aircraft’s wing-fuselage blend is designed to cut drag and lift efficiency to the point where less power is needed for the same mission.

There are trade-offs. A lifting fuselage means the transition between cabin and wings is smoother, but flight control becomes trickier. Instead of the traditional tail and elevator, Gen-ee would use elevons, similar to some military jets and flying wings. That places more burden on flight control software, testing and certification.
Electric propulsion and a lighter airframe
The second lever for cutting energy use is the propulsion chain. By relying on fully electric motors rather than combustion engines, Eenuee is targeting overall efficiency close to 90% from battery to propeller.
For comparison, thermal engines waste a large share of energy as heat. Electric motors are not perfect, but power electronics plus modern motors already operate at much higher efficiency levels than turboprops.
Weight: the hidden enemy
Weight is the other major battleground. Every extra kilogram is carried on every single flight for the entire life of the aircraft. Eenuee’s engineers are obsessed with grams.
To keep mass down, the team plans extensive use of carbon-fibre composites and high-performance aluminium. They have also chosen a non-pressurised cabin, which significantly simplifies the structure.
- Maximum take-off weight targeted: 5.6 tonnes
- CS-23 category limit: 8.6 tonnes
- Number of passengers: 19
- Target range: 500 km on batteries
By staying well below the weight ceiling for its certification category, Gen-ee should need less thrust, smaller batteries and therefore less energy per seat-kilometre.
From runway to river: a multisurface machine
One of the most unexpected features of the project is its amphibious ambition. On top of conventional runway operations, Eenuee is working on a version that can take off and land on water.
Instead of traditional floats, the aircraft would use hydrofoils: underwater wings that lift the fuselage out of the water at speed. Once the hull rises, drag drops sharply, making acceleration and take-off far easier.
Hydrofoils are intended to let the aircraft “fly” over water before it actually takes off, reducing drag in the same way as high-speed racing boats.
That concept, already used in sailing and powerboat racing, could open new markets for the aircraft:
| Region | Potential use case |
|---|---|
| Scandinavia | Lakes and fjords linking remote coastal towns |
| Canada | Water access to northern communities and mining sites |
| Southeast Asia | River and coastal hops between islands and riverside cities |
Unlike classic seaplanes with floats, which need heavy, specialised maintenance and operate only on water, Eenuee’s design is meant to switch between runway and water without modification. That versatility is central to their business pitch.
Charging, maintenance and what airports need to change
Eenuee insists that Gen-ee is being designed around existing aerodromes. That means no new runways, no major alterations to taxiways, and no exotic handling equipment.
The main new requirement is charging. The plan is to use systems conceptually similar to high-power fast chargers for electric cars, scaled to aircraft needs and integrated into airport operations.
On the ground, the list of needs is fairly classic:
- Basic passenger facilities for safe boarding and waiting
- One or more maintenance centres able to handle composite structures and electric systems
- Ground vehicles, potentially also electrified, to service the aircraft
For smaller regional airports seeking new routes without big capital projects, that kind of minimal upgrade path is attractive.
Certification hurdles and the 2029 target
Gen-ee is still at the development stage. Eenuee has just signed a strategic partnership with Duqueine Group, a composites specialist, to speed up work on the airframe.
The roadmap is ambitious. A first flight is targeted for 2029, with certification under EASA’s CS-23 rules. Between now and then, the team faces a dense schedule of risk analysis, simulation, and physical testing.
Scaled demonstrators before full size
To shake out problems early, the company is building flying demonstrators at reduced scale. Current test aircraft are at 1:7 scale, with a 1:4 model planned to address manufacturing and industrialisation questions.
Scaled demonstrators allow engineers to identify aerodynamic quirks and control issues while changes are still relatively cheap.
Certification work, including the Design Organisation Approval (DOA) process, is expected to start around 2027, giving regulators time to get comfortable with the novel design, electric systems and amphibious features.
Where this fits in the wider decarbonisation puzzle
Gen-ee does not exist in a vacuum. Aviation’s climate strategy currently leans heavily on sustainable aviation fuel (SAF), incremental efficiency gains and, in the longer term, hydrogen.
Battery-electric aircraft are constrained by energy density. Jet fuel still packs far more energy per kilogram than the best commercial batteries. That is why Eenuee focuses on short regional hops rather than long-haul flights.
At the same time, these short routes often have the highest emissions per passenger-kilometre, because aircraft spend more time in take-off and climb phases. Replacing them with highly efficient electric flights could shave off a noticeable share of emissions in regions with dense regional networks.
Key concepts worth unpacking
A few technical terms matter here:
- Blended wing body (BWB): an aircraft where wings and fuselage form a single, continuous lifting surface, reducing drag and potentially improving fuel or energy efficiency.
- Lift-to-drag ratio: a simple indicator of aerodynamic efficiency. Higher values mean the aircraft generates more lift for the same drag, so it can cruise with less power.
- CS-23: the European certification standard that covers small aircraft, typically up to 19 passengers. It defines safety, performance and design requirements.
For regional operators, the economic equation will be just as important as the technical story. If maintenance on a lighter composite structure and simple electric powertrain proves cheaper than turboprop overhauls and fuel, the lower energy use could translate directly into lower operating costs.
Scenarios run by industry analysts often suggest that electric regional aircraft could first take root on subsidised public-service routes in mountainous or sparsely populated areas. From there, they might extend to dense corridors where short flights compete with rail, especially if regulators tighten emissions constraints or increase taxes on jet fuel.
The risks are clear: battery technology may not progress as fast as expected, certification of a non-traditional airframe could be slower than planned, and market acceptance is not guaranteed. On the other hand, if Eenuee and similar projects manage to prove reliability and bring costs down, they could shift how regions think about connectivity, using electricity and water as strategic assets rather than constraints.
