Naples, 11 December 2025 – The ALRIGH2T General Assembly, the European project dedicated to the development of liquid hydrogen (LH₂) refuelling technologies for aviation, successfully concluded with strong participation. The meeting took place in Naples from 9 to 11 December and was hosted by project partner ATENA – Distretto Alta Tecnologia Energia Ambiente. Leading experts and project activity managers gathered to review the current state of progress and define the roadmap for the coming months.
The meeting brought together representatives of the 20 project partners from seven European countries and Israel, including companies, research institutes and universities involved in the project coordinated by ENEA. The shared objective remains the development and demonstration of innovative solutions for the safe and efficient refuelling of aircraft and ground vehicles with liquid hydrogen, contributing to the decarbonisation of the aviation sector and the transition towards zero-emission aviation (alrigh2t.eu).
During the sessions, the various Work Packages presented progress across key activities: from the development of refuelling technologies (both direct refuelling and tank exchange), to the definition of operational procedures, as well as technical, environmental, safety and regulatory aspects. The consortium also explored upcoming demonstration activities, which will include real-world tests at major European airports, among them Milan Malpensa and a reference airport in Paris, with the goal of achieving an advanced Technology Readiness Level (TRL) by the end of the project.
A particularly significant moment of the three-day meeting was the HAZID (Hazard Identification) session, focused on the identification and preliminary assessment of risks associated with hydrogen refuelling technologies. The workshop involved technical experts and project partners in a systematic analysis of potential risk scenarios, laying the groundwork for the development of mitigation strategies and for the subsequent phases of detailed design and solution validation.
The ALRIGH2T project (Airport-Level DemonstRatIon of Ground refuelling of Liquid Hydrogen for Aviation), funded under the Horizon Europe programme with a budget of approximately €10 million, aims to transform liquid hydrogen refuelling at airports by developing cutting-edge technologies, operational protocols, digital twin models and scalable, sustainable processes. This commitment represents a key pillar of the European strategy for the decarbonisation of aviation and for strengthening the role of airports as strategic hubs within the hydrogen economy.
