The European aviation sector is at the forefront of the decarbonization challenge, with a particular focus on transitioning to zero-emission flights by 2050. This ambitious goal is vital, considering the aviation sector's significant contribution to global CO₂ emissions. To address this, the sector is turning to hydrogen-powered aircraft as a key solution. However, utilizing hydrogen as a fuel in aviation comes with its own set of challenges, including the need for innovative storage solutions due to hydrogen's unique properties. The Overleaf project, supported by European funds, is dedicated to overcoming these obstacles by improving hydrogen storage technology. Through collaborative efforts, researchers are developing new tank designs and leak detection systems to ensure the safety and efficiency of using hydrogen as fuel. These innovations not only have the potential to revolutionize aviation but also to benefit other industries such as rail transportation and telecommunications. Experts emphasize the importance of European institutions taking a proactive role in promoting hydrogen technology in aviation. Clear incentives, regulations, and financial mechanisms are essential to accelerate the transition towards e-kerosene and hydrogen. By fostering a supportive environment for green fuel startups and encouraging collaboration with established oil companies, the aviation sector can move closer to achieving its environmental targets while driving economic growth and job creation. While the path to zero-emission flights may be challenging, the advancements in hydrogen technology offer promising solutions. By pushing the boundaries of innovation and collaboration, Europe's aviation sector is poised to lead the way towards a greener and more sustainable future.
