Dutch carrier KLM has partnered with hydrogen-electric powertrain developer ZeroAvia to push forward advancements in aviation. The collaboration includes plans for a large turboprop trial flight in 2026 utilizing the ZA2000 powertrain. ZeroAvia, supported by Airbus, is seeking design certification for its ZA600 powertrain to power small regional aircraft, while also developing the ZA2000 for larger turboprops. The partners aim to showcase the sustainability benefits of hydrogen-electric flights, with potential climate impact reductions of up to 90% compared to traditional flights. Efforts are underway to secure regulatory permits, ensure a supply of liquid hydrogen fuel, and establish infrastructure for aircraft fueling, with a focus on advancing hydrogen-electric operations in the European Union. ZeroAvia's timeline includes certification of the ZA600 in 2025 and the ZA2000 in 2027, followed by exploring a regional jet variant. KLM and ZeroAvia's joint efforts signal a positive outlook towards the adoption of hydrogen-electric aircraft in commercial aviation, with a strong emphasis on innovation, sustainability, and technology.
