ZeroAvia, a pioneer in hydrogen propulsion, has secured a Small Business Innovation Research grant from the Air Force Research Laboratory for a feasibility study to integrate hydrogen propulsion in a Cessna Caravan. The Air Force unit AFWERX is focusing on key research questions in the Department of the Air Force, with hydrogen power for autonomous aircraft being a primary area of interest. The grant aims to explore the benefits of hydrogen power, such as its low temperature signature and noise levels, which can reduce detectability, particularly crucial for defense applications. Additionally, the ability to produce hydrogen aviation fuel on-site using water and electric power is highlighted as a strategic advantage for forward operating environments. Val Miftakhov, the CEO of ZeroAvia, views this grant as a significant step in the exploration of hydrogen fuel cell technology in heavy unmanned aircraft, emphasizing the potential for cost reduction, enhanced capabilities, and reduced risks in fuel supply. This collaboration with the U.S. Air Force signals a positive outlook for the future of hydrogen propulsion in the aviation sector.
