American Airlines has entered a significant partnership with ZeroAvia by signing a conditional purchase agreement for 100 hydrogen-electric engines, indicating a move towards sustainable aviation. This strategic move involves powering regional jet aircraft with zero inflight emissions, apart from water vapor, setting the stage for a low-carbon future in commercial aviation. The airline's increased investment in ZeroAvia through participation in the company's Series C financing round demonstrates a continued dedication to innovative and sustainable aviation technologies. ZeroAvia, a pioneer in developing hydrogen-electric engines for commercial aircraft, is advancing prototype testing for a 20-seat plane and working on engines for larger aircraft like the Bombardier CRJ700. American Airlines' CEO, Robert Isom, underscores the significance of investing in alternative propulsion technologies to achieve a net-zero greenhouse gas emissions target by 2050. The airline's commitment to sustainability is further reflected in its fleet renewal efforts, sustainability investments, and partnerships for low-carbon sustainable aviation fuel and carbon removal processes. ZeroAvia's hydrogen-electric engines operate by using hydrogen in fuel cells to produce electricity for electric motors, resulting in low-temperature water vapor emissions, offering a cleaner alternative to traditional jet fuel. This technological innovation not only promotes environmental sustainability but also potentially offers cost savings. Val Miftakhov, the CEO of ZeroAvia, praises American Airlines' support for driving innovation in clean aircraft propulsion and expresses optimism in achieving a clean future for flight. The collaboration between American Airlines and ZeroAvia marks a positive step towards revolutionizing the aviation industry with sustainable and eco-friendly practices.
