Ecojet Airlines, a climate-friendly UK regional start-up founded by green energy entrepreneur Dale Vince, has decided to delay the launch of its services until early 2025 to ensure long-term success and sustainability. The airline, headquartered in Edinburgh, aims to differentiate itself from previous regional start-ups by prioritizing sustainability in both environmental and business aspects. Ecojet has applied for an air operator's certificate and is working on establishing its IATA designation and callsigns. Despite facing challenges, the company is determined to build a stable and reliable airline in the UK aviation market. The recent departure of the chief operating officer has not deterred Ecojet's commitment to its vision. Ecojet's plans also include the conversion of its fleet to use hydrogen fuel cell powertrains from ZeroAvia, with the aim of conducting its first commercial flights with green hydrogen in 2026. The company has ordered engines suitable for its aircraft and is optimistic about the accelerating development of hydrogen technology. Additionally, Ecojet has relocated to a new office near Edinburgh airport to accommodate its growth plan. Furthermore, there has been a change in the company's shareholding structure, with Dale Vince acquiring a significant number of shares. The collaboration with ZeroAvia, investment in hydrogen technology, and strategic business decisions reflect Ecojet's positive outlook towards building a climate-friendly airline in the UK market.
