ZeroAvia has expanded its clean propulsion system development with the acquisition of nine new patents, bringing the total to 45 granted rights in electric propulsion technologies and hydrogen engines for aviation. The patented innovations include an integrated hydrogen electric motor designed for aircraft models such as ATR and Dash 8 as part of the ZA2000 system, aiming to provide zero-emission, energy-dense propulsion for 40- to 80-seat aircraft. Additionally, advancements in HTPEM fuel cells, thermal management, cryogenic systems, and catalysts have been protected by patents, enhancing the performance and durability of hydrogen propulsion systems. Notably, one system allows for the reuse of heat generated during hydrogen fueling to power other electrical systems, improving energy efficiency during ground operations. ZeroAvia's focus on hydrogen aviation technologies, supported by a strong intellectual property portfolio, demonstrates its commitment to technological leadership in the commercial engine market, enabling applications like hybrid aircraft, eVTOL, and unmanned vehicles. With manufacturers like Airbus and Boeing advancing hydrogen-compatible airframes, ZeroAvia's propulsion system patents play a crucial role in maintaining technological independence and leadership in the aviation industry.
