The aviation industry is facing the urgent need to transition to zero-emission flights due to the sector's significant contribution to global CO₂ emissions. Europe, under the European Green Deal, aims to cut transport emissions by 90% by 2050, driving the development of hydrogen-powered aviation. The Overleaf project, led by Aciturri and supported by the EU, is at the forefront of this innovation. It focuses on revolutionizing hydrogen storage for aviation by enhancing capacity and efficiency while reducing weight and costs. The project's cutting-edge tank design, advanced manufacturing processes, and safety enhancements through leak detection technologies highlight its commitment to sustainable aviation. Collaborations with top institutions ensure the optimization of tank geometry and material composition for safe and efficient hydrogen storage. The project's impact extends to other industries like rail transportation and telecommunications through the development of high-performance materials and manufacturing techniques. Despite challenges like certification processes and infrastructure transformation, Europe's commitment to hydrogen-powered flight demonstrates a clear pathway to achieving its climate targets. Continued investment, innovation, and policy support are crucial for Europe to maintain its leadership in sustainable aviation and secure a zero-emission future in the skies.
