Cargo delivery HE endurance

Electric battery replacement and new designs
When batteries tap out, Stralis systems keep going with hydrogen-electric long-range endurance with large payloads for high-volume commercial use cases.
Stralis–HE
A hydrogen-electric fuel cell system designed for endurance
Aviation is electrifying, but batteries alone are limited. Our scalable hydrogen-electric system integrates a fuel cell, liquid hydrogen tanks, and electric motors for UAVs and aircraft. Our technology is 6x lighter than the current state of the art, enabling up to 30x longer flights and a greater payload than battery-electric.

Aviation is electrifying but batteries alone are limited
Batteries limit payload and range. Existing fuel cells extend range but still constrain payload. Stralis hydrogen-electric propulsion unlocks long-range flight with large payloads for high-volume commercial use cases.
Aircraft developers
Fixed wing electric and eVTOL
Our hydrogen-electric propulsion system can upgrade battery-electric aircraft, replace conventional engines, and be integrated into new aircraft designs.
