American Airlines is at the forefront of efforts to decarbonize aviation by exploring the potential of hydrogen as a low-carbon fuel source. Hydrogen, when produced using renewable electricity, offers the promise of significantly reducing emissions in the aviation sector. The airline is actively involved in catalyzing the development of hydrogen-electric propulsion technology, partnering with companies like ZeroAvia to advance hydrogen-powered regional jets. These endeavors include retrofitting existing aircraft with zero-emissions hydrogen-electric powertrains that utilize green hydrogen, generated through electrolysis and stored near airports. While hydrogen holds great promise, challenges such as the need for significant investments, infrastructure development, regulatory approvals, and cost competitiveness need to be addressed for its widespread adoption in aviation. American Airlines is also engaged in collaborations with other industry leaders like Boeing and NASA to drive forward other next-generation aircraft technologies aimed at reducing emissions and increasing sustainability. In July 2024, American Airlines announced a conditional purchase agreement for 100 hydrogen-electric engines from ZeroAvia, marking a significant step towards incorporating hydrogen propulsion in its regional jet aircraft. These initiatives reflect American Airlines' commitment to advancing innovative solutions for a more sustainable aviation industry, ensuring a greener future for air travel.
