Her objective will be to lead ZeroAvia as it commercialises its products and continues to advance its hydrogen-electric propulsion technology.
The company remains focused on accelerating the development and certification of hydrogen-electric propulsion systems designed for aviation.
Ourmières-Widener also underlined the broader potential of the technology for aerospace and defence applications, stressing the importance of collaboration in bringing the transition forward.
“Hydrogen-electric propulsion has the potential to transform aerospace and defense applications, and collaboration is essential to accelerating that transition,” she said.
