Dutch carrier KLM is making strides towards sustainable aviation by partnering with ZeroAvia, a sustainable aircraft firm, to conduct a test flight powered by liquid hydrogen fuel within the next two years. This innovative project aims to showcase the potential of hydrogen-electric engines in reducing emissions and advancing cleaner flight technology.
ZeroAvia’s ZA2000 hydrogen-electric engines will be utilized for the test flight, utilizing hydrogen in fuel cells to power electric motors that drive the propellers of large regional jets. The key highlight of this technology is the minimal emissions it produces, with only low-temperature water vapor being released during operation. A recent study by Clean Sky and McKinsey highlighted the significant environmental benefits of hydrogen-powered aviation, estimating reductions in climate impact ranging from 50 to 90 percent compared to traditional jet fuel.
KLM views this project as a crucial step towards adopting cleaner flights within its network. The airline plans to conduct an initial A-to-B flight demonstration between two airport locations in 2026, providing valuable insights and data to support the transition to more sustainable aviation practices. Key focus areas for the project include securing regulatory permits, ensuring a stable supply of liquid hydrogen fuel, and establishing the necessary infrastructure for aircraft fuelling.
The announcement of this partnership comes at a time when Amsterdam Schiphol Airport is trialling a new hydrogen-based facility to power aircraft on the ground, showcasing a broader industry shift towards sustainable aviation solutions. Additionally, ZeroAvia recently secured a significant $116 million investment in a 2023 funding round, underscoring the growing interest and support for hydrogen-electric technologies in the aviation sector.
Sergey Kiselev, Chief Business Officer at ZeroAvia, emphasized the increasing seriousness with which major airlines are exploring hydrogen-electric solutions as a viable pathway towards zero-emission flights. KLM Cityhopper’s Managing Director, Maarten Koopmans, echoed this sentiment by highlighting the airline’s commitment to researching and implementing various sustainable technologies, including electric, hydrogen, and hybrid-powered flights.
Overall, the collaboration between KLM and ZeroAvia represents a significant milestone in the journey towards greener aviation practices. By leveraging innovative technologies and partnerships, the aviation industry is paving the way for a more sustainable and environmentally conscious future of air travel.
