American Airlines has announced its investment in ZeroAvia, a leader in hydrogen-electric, zero-emission aviation. In addition to the investment, a memorandum of understanding provides American the opportunity to order up to 100 engines from ZeroAvia’s hydrogen-electric powertrain development program. The engines are intended to power regional jet aircraft with zero emissions.ZeroAvia is working to achieve certain type certifications of its innovative propulsion technology that will pave the way for the engines to be incorporated into the regional jet market in the future. The ZA2000-RJ powertrain is anticipated to enable passengers to fly in zero-emission regional jets as early as the late 2020s.ZeroAvia is a leader in zero-emission aviation, focused on hydrogen-electric aviation solutions to address a variety of markets, initially targeting a 300-mile range in 9–19 seat aircraft by 2024, and up to 700-mile range in 40–80 seat aircraft by 2026. Based in the UK and USA, ZeroAvia has already secured experimental certificates for its two-prototype aircraft from the CAA and FAA, passed significant flight test milestones, secured a number of key partnerships with major aircraft OEMs and major global airlines, and is on track for commercial operations in 2024. The company’s expanding UK operations are supported by grants from UK’s Aerospace Technology Institute and Innovate UK, and ZeroAvia is part of the UK Government’s Jet Zero Council.
