ZeroAvia and KLM to demonstrate Hydrogen-Electric flight with ZA2000 engines, targeting 90% climate impact reduction.
ZeroAvia and KLM Royal Dutch Airlines announced their collaboration on a demonstration flight using ZeroAvia’s ZA2000 hydrogen-electric engines for large regional turboprops. These hydrogen-electric engines utilize hydrogen in fuel cells to generate electricity, which powers electric motors to turn the aircraft’s propellers. The only emission produced is low-temperature water vapor. Consequently, studies estimate a climate impact reduction of up to 90% compared to typical kerosene-fueled flights.
James Peck, Chief Customer Officer of 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.”
As a key milestone, the companies plan to conduct an initial A-to-B flight demonstration between two airport locations in 2026. They will first identify the optimal airport pair. Additionally, immediate efforts will focus on securing regulatory permits for the flight, ensuring a supply of liquid hydrogen fuel, and establishing the necessary infrastructure for aircraft fueling. Through this collaboration, KLM and ZeroAvia aim to provide evidence supporting the adoption of cleaner flights within KLM’s network. Moreover, this demonstration project will expedite the development of hydrogen aircraft operations concepts across the EU.
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.”

Having conducted extensive testing, ZeroAvia’s ZA600 engine prototype was tested aboard a Dornier 228 aircraft at its UK base. Moreover, the company performed advanced ground tests in the US and UK. These tests focused on essential technologies for the ZA2000 system, including cryogenic LH2 tanks and high-temperature PEM fuel cells. Additionally, the ZA2000 system is designed to support regional turboprop aircraft like the ATR72 and Dash 8 400, accommodating up to 80 passengers.
Q. – What technology does the ZA2000 engine use?
A. – Hydrogen in fuel cells to generate electricity.
Q. – What is the estimated climate impact reduction of the ZA2000?
A. – Up to 90%.
