Switching to hydrogen-electric propulsion systems will provide operators with:

Zero-emission flight and fuel

Tackling 95% of climate change impact: clean hydrogen in fuel cells generating electricity to power electric motors

Lower and more stable fuel costs

Green hydrogen cost set to be lower than jet kerosene and SAF; fuel cell systems offer more energy efficient use of fuel

Significantly lower maintenance cost

ZeroAvia’s hydrogen-electric powertrain promises significant extension of flight hours between major servicing events

Reduced noise and air pollution

Removing the noise and exhaust of combustion engines to reduce disruption and air quality impacts on communities close to airports

Our Products

We are working with operators to extend the life of existing fleet via retrofit programs or bring new hydrogen-electric aircraft into service via our line-fit agreements with OEMs.

We are focused on three key product offerings initially

SuperStack Flex

A scalable, lightweight, aerospace-grade hydrogen fuel cell system to support propulsion, APU and mission systems power.
