The European aviation sector is facing the challenge of transitioning to zero-emission to meet the environmental goals set by the European Green Deal. Hydrogen-powered aircraft are at the forefront of this revolution, offering a solution to reduce CO2 emissions significantly. However, storing hydrogen for aviation presents unique challenges due to its low volumetric energy density, requiring new lightweight tanks and distribution systems to ensure safety and efficiency. The Overleaf project, led by Emma Celeste Lope Retuerto, aims to tackle these challenges with innovative tank designs and leak detection sensors. The project has made significant progress in tank development and leakage prevention, paving the way for practical solutions within a few years. This initiative not only benefits the aviation industry but also has the potential to drive advancements in other sectors such as rail transportation and telecommunications. European institutions, including the EU, are called upon to establish a comprehensive framework of incentives and rules to support the adoption of hydrogen in aviation. Krisztina Hencz from Transport & Environment emphasizes the importance of creating a supportive industrial strategy that promotes e-kerosene and hydrogen, urging governments to seize the opportunity for decarbonization and job creation. The involvement of big oil companies in supporting start-ups in the green fuels market is highlighted as crucial for the success of these initiatives. While challenges lie ahead, the potential for achieving the environmental targets of the Green Deal in the aviation sector through hydrogen-powered aircraft remains promising.
