Ecojet Airlines, based in Edinburgh, has postponed its launch to 2025 and disclosed plans to utilize ATR72-600 aircraft for its operations. Initially targeted for early 2024, the delay aims to ensure a comprehensive and successful launch, with CEO Brent Smith emphasizing the importance of getting it right. The company's vision includes a significant reduction in CO2 emissions, with intentions to introduce green hydrogen technology. Ecojet has applied for an air operator's certificate from the UK Civil Aviation Authority and anticipates acquiring IATA designation and callsigns soon. Furthermore, the airline plans to incorporate hydrogen-electric engines from ZeroAvia, particularly in DHC-6 Twin Otters, with hopes to start utilizing green hydrogen by 2026. The partnership with ZeroAvia involves procuring ZA2000 powertrains for ATRs, with a focus on sustainable aviation solutions. Despite the delay, Ecojet's strategic decisions reflect a positive sentiment towards innovation and environmental consciousness in the aviation industry. The involvement of investors like AMG Ventures and the company's commitment to implementing green technology signify a promising future for Ecojet Airlines in the sustainable aviation sector.
