Hydrogen-electric engines use hydrogen in fuel cells to generate electricity, which is then used to power electric motors to turn the aircraft’s propellers.
The only emission is low-temperature water vapor, with studies therefore estimating an up to 90% reduction in climate impact when compared with typical kerosene-fuelled flights.
As a first major target milestone, the companies aim to conduct an initial A-to-B flight demonstration between two airport locations in 2026.
As well as identifying the optimal airport pair, immediate workstreams will be working towards regulatory permits to fly and ensuring supply of liquid hydrogen fuel and putting in place the supporting infrastructure for aircraft fuelling.
With this collaboration, KLM and ZeroAvia are providing the evidence-base for adoption of cleaner flights on KLM’s network and the project will accelerate the development of concepts of operations for hydrogen aircraft across the EU.
James Peck, Chief Customer Officer, ZeroAvia, said: “The world’s largest airlines are diving in to explore hydrogen-electric as a potential solution with increasing seriousness. We can’t wait to work with KLM, being an airline with such rich history, as we look towards a clean future for the industry.”
Maarten Koopmans, Managing Director, KLM Cityhopper said: “KLM aims to be a front-runner in the journey towards a more sustainable future in aviation. That's why we actively support and encourage innovation to drive industry change. When it comes to the future of zero-emission flights, KLM supports various technologies and innovations simultaneously. Together with our sector partners, we are conducting research on electric, hydrogen, and hybrid-powered flights and exploring ways to expedite these advancements."
