Can we develop a fully electric helicopter?
Cell energy density evolution scenarios
Lithium-sulfur batteries commercialize,
offering gravimetric cell energy density
of up to ~2,510 Wh/kg, pushing base
case CAGR levels by 2.5%
Targets from Innolith are met
with prior cell density growth
rates of 7% CAGR (2020-2025)
and their batteries are
commercialized at scale
Traditional Lithium-ion
batteries continue to progress
up to 350 Wh/kg and solid-
state batteries are scaled
- Best case
- Base case
Even after density develops sufficiently, there will be a 5+ year delay for
wider adoption (certification, production timeline, adaption for aviation usage)
Good confidence,
current investment
focus mainly driven by
automotive industry
Low confidence,
enabling technologies
still in early stage and
any investments for
industrialization could
probably not be driven
by automotive industry
Note: LHS: Assumes that targets from Tesla, QuantumScape, Innolith etc. will be met and that solid state batteries commercialize; RHS: Assumes all else equal; 1) Next to battery cell density, battery degradation
improvement critical is to secure sufficient energy capture;
Source: Expert interviews
Battery cells energy density is the main hurdle to achieve full electric flight
2030+ evolution remains uncertain due to lower automotive investment appetite

Trade-off between Range and Payload generates different operating scenarios

Long Light Single Helicopter* Range & Payload: Full Electric vs Turbine
Increase in Battery capacity

Take Off
Power

Key Evidences
Payload reduction in favour of
Battery Capacity allows to
increase flight Range
Power needed to take off requires
a minimum battery size to allow
the Helicopter to take-off
Despite battery density expected
growth, Full Electric Helicopter
does not guarantee the same
Payload and Range as of a
Turbine HC

The Hybrid Helicopter
Why add electric propulsion?
• New operational scenarios
(e.g., congested hostile areas)
• Mitigate operational risks
• Simplify training procedures
• Improve public acceptance
• Higher efficiency propulsion
 lower operating cost
• Lower CO2 output
 environmental benefits
