UK-based startup airline EcoJet has made a groundbreaking move by placing an order for 22 ZeroAvia hydrogen-electric ZA2000 engines, with the option for an additional 40 engines. These engines are designed for retrofitting to 40-80 seat regional turboprops, marking a significant step towards sustainable air travel. EcoJet, founded by Dale Vince, aims to pioneer net-zero, emission-free air travel, positioning itself as the world's first electric airline. The partnership between EcoJet and ZeroAvia signifies a commitment to revolutionizing aviation with a sustainable approach. The deposit schedule ensures that EcoJet secures early production slots for the powertrains post-certification. While EcoJet plans to launch services in late 2024 with conventionally powered aircraft, the subsequent retrofit with ZeroAvia's technology showcases a shift towards renewable power. ZeroAvia's founder, Val Miftakhov, praises EcoJet's vision and contribution to making renewable power a reality in the UK. This collaboration not only highlights the innovative strides in sustainable aviation but also emphasizes the joint effort to drive the future of emission-free air travel.
