The aviation industry in Europe is facing a critical juncture as efforts intensify to decarbonize the skies. With aviation contributing significantly to global CO2 emissions, the urgency to transition to zero-emission flight has never been more pressing. The European Green Deal's ambitious target of reducing transport emissions by 90% by 2050 has pushed hydrogen-powered aviation to the forefront of innovation. At the center of this shift is the Overleaf project, an EU-funded initiative addressing the challenge of hydrogen storage for aviation. The Overleaf project, led by Aciturri, aims to develop advanced hydrogen storage solutions that increase capacity, reduce weight, and minimize costs. Through cutting-edge tank designs and innovative manufacturing processes like additive manufacturing and automated fibre placement, Overleaf is working to make hydrogen a viable and accessible fuel for aviation, supporting Europe's climate goals. Safety measures, including hydrogen leak detection systems and advanced inspection techniques, are crucial to ensuring the reliability of hydrogen storage. The project is not only revolutionizing hydrogen storage for aviation but also has broader applications in other sectors such as rail transportation and telecommunications. By collaborating with leading institutions and focusing on safety and efficiency, Overleaf is driving sustainable aviation innovation in Europe. Despite challenges like certification processes and infrastructure transformation, Europe's commitment to hydrogen-powered flight underlines its leadership in sustainable aviation and its potential to be a global frontrunner in green technology.
