Mare Group Spa has received approval from the European Commission for the Cryostar project, aimed at developing an innovative certification methodology for cryogenic tanks for liquid hydrogen in commercial aircraft. This project, with a duration of 24 months, is part of the Horizon Europe Clean Aviation Joint Undertaking program and focuses on tackling the challenge of safely storing liquid hydrogen on board aircraft during the aerospace energy transition. The activities, which will be fully financed by non-repayable grants, amount to EUR 5.1 million, with a significant share allocated to Mare Group. The goal is to integrate these novel tanks into the rear fuselage of commercial aircraft to ensure they are leak-tight, impact-resistant, and compliant with future regulatory standards. Mare Group, a key industrial partner in the project, will be responsible for developing and validating structural systems and containment devices to ensure the tank's integrity during emergency scenarios. This will be achieved through extensive full-scale testing, advanced numerical simulations, and collaboration with aviation authorities. The Cryostar consortium is a collaborative effort involving five universities, research centers, and eight high-tech companies. This multidisciplinary approach aims to leverage engineering, academic, and regulatory expertise at the continental level to address the challenges of liquid hydrogen storage in aviation. Overall, the approval of the Cryostar project signifies a positive step towards enhancing the safety and efficiency of liquid hydrogen storage in future commercial aircraft, offering a promising solution for the aerospace industry.
