Our Legacy


H55 IS THE TECHNOLOGICAL SPIN-OFF OF SOLAR IMPULSE

Solar Impulse was the first electric airplane to have flown around the world,
propelled only by solar energy.

A pioneering journey paving the way for sustainable aviation.

With 2 electric airplanes, Solar Impulse’s clean propulsion and battery
technologies, successfully flew 46’000 km, in 550 flying hours, achieving 14 FAI
world records including the longest solo-flight (André Borschberg). All with
clean technologies.

Our Technology


ELECTRIC PROPULSION SYSTEM (EPS)

H55’s EPS is composed of the Energy Storage System (ESS) which includes battery
packs, battery management systems, and all interfaces, as well as the Electric
Power Unit (EPU) with a motor and a motor controller.

H55 EPS is the pulse of electric aviation and has already been integrated and
flown within 4 different types of aircraft. Meeting all certification
requirements, H55’s technology has demonstrated its efficiency and reliability
in real flight conditions.

H55 global customers are comprised of OEMs, component manufacturers and
operators. The modularity of the systems allows for integration in different
types of aircraft configurations including fixed wing applications, for both
existing and new designs (in the CS23 and CS25 certification categories), as
well as for new aviation designs featuring high power distributed electric
propulsion systems.

CURRENT PROJECTS

Accelerating our ability in bringing certified aircraft to the market is
realized through the modularity of H55 solutions, our recognized ability in
customizing our technology in a cost and time efficient manner, and supporting
customers on airplane integration and certification

The adaptability of H55 solutions fits well into multiple aircraft designs
covering the transformation of existing airplanes through STC programs,
electrifying new and existing designs for commuters, STOL and eVTOL aircrafts.



De Havilland Dash-8 - Commuter Aircraft


PRATT & WHITNEY CANADA

H55 has been selected to develop the Energy Storage System (ESS) for an electric
hybrid 49 seat flight demonstrator De-havilland Dash 8 aircraft.

An important step toward carbon-neutral regional air mobility, the hybrid
aircraft is aiming for a 30% improvement in fuel efficiency and an equivalent
reduction in CO₂ emissions compared to today’s most advanced turbo propulsion
engines
