Switching to hydrogen-electric propulsion systems will enable:

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

Partners

We are working with some of the leading airframe manufacturers on enabling zero-emission flights
