4 SUSTAINABILITY REPORT ENVIRONMENTAL MATTERS

The emergence of disruptive low-carbon/decarbonised technologies – electric aviation, hydrogen aviation – is both a tremendous opportunity for a successful environmental transition in the aviation sector and a challenge for the entire value chain. Aware that the capacity for innovation and partnership work are essential to meet this challenge, in 2024 Groupe ADP continued the collaborative work begun in 2021. In 2024, this resulted in: u participation as an active member in the European alliance AZEA (Alliance for Zero Emission Aviation), which aims to prepare the aviation ecosystem for the entry into service of aircraft powered by hydrogen and electricity. Groupe ADP contributes to the various working groups by sharing its expertise in airport development and safety; u continuation of pre-feasibility studies on the structuring of a hydrogen logistics chain serving Paris airports. In 2021, Groupe ADP, Airbus and Air Liquide jointly conducted studies aimed at characterising the volumes of hydrogen required and the challenges of integrating hydrogen infrastructure at the airports in the Paris region. In 2023, Groupe ADP undertook studies on the operation and infrastructure of the upstream value chain, outside the airport, in order to qualify the possibility of transporting electricity for hydrogen production at airports or hydrogen directly in gaseous form; u in October 2023, a new step was taken with GRTgaz to focus on the conditions for transporting hydrogen gas to Paris-Charles de Gaulle and Paris-Orly airports, with a view to liquefying and storing it before distributing it to aircraft (https://presse.groupeadp.fr/partenariatgrtgaz/). The initial results of these studies, which was unveiled in autumn 2024 at the Meaux meetings, mean that we can be reasonably confident that we will be able to transport hydrogen in gaseous form to Paris airports in the required quantities. Several possible transport corridors have been identified. These pre-feasibility studies on the integration of hydrogen infrastructure and equipment at our airports will need to be supplemented by hazard studies. In this respect, Groupe ADP is contributing to a number of pioneering initiatives aimed at characterising the hydrogen risk: u Groupe ADP's contribution to the completion of the hazard study, led by France Hydrogen, as part of the revision of section No. 4715 of the Regulation of Installations Classified for the Protection of the Environment (ICPE). The purpose of this study is to create, in collaboration with the Directorate- General for Risk Prevention (DGPR), a registration order for hydrogen uses requiring 1 to 5 tonnes of storage; u the signing of partnerships with low-carbon regional and general aviation manufacturers, in particular Zero Avia and Universal Hydrogen, in order to study the methods of integrating these aircraft at our airports; u participation in consortia managing co-financed R&T projects. For example, since 2023, Groupe ADP has been contributing to the OPS H2 project, co-financed by the DGAC through the CORAC programme, which aims to characterise all the risks related to the operations of hydrogen aircraft and associated infrastructure in airports.

Since 2024, Groupe ADP has also played an active part in the ALRIGH2T project co-financed by the European Commission as part of the Horizon Europe call for projects. ALRIGH2T aims to offer demonstration solutions for the integration of two aircraft featuring technological breakthroughs at European airports; u the creation, in June 2023, of an alliance between Groupe ADP and six leaders in decarbonised regional aviation (Pipistrel, Universal Hydrogen, ZeroAvia, Beyond Aero, VoltAero and Daher) to accelerate the arrival by 2030 of aircraft with 2 to 100 seats with electric or hydrogen propulsion at its airfields and at Paris Le Bourget, Paris-Orly and Paris-Charles de Gaulle airports (https://presse.groupeadp.fr/strongle-groupe-adp-sallie avec-les-leaders-de-laviation-regionale-decarbonee-pour accelerer-la-transition-environnementale-du-secteurstrong- 24197/?lang=en). The actions undertaken since 2022 are continuing apace, including: u Groupe ADP's investment in the Hy24 fund, a benchmark fund in the hydrogen field, which is deploying €2 billion over ten years to accelerate the hydrogen economy (investment in specialised hydrogen companies and projects); u as part of the Memorandum of Understanding signed in 2024 between Embraer, EVE and Groupe ADP, the installation of a hydrogen infrastructure will be studied at Paris-Le Bourget airport to support the operations of the Energia family of aircraft, which is expected to comprise two models of 19- and 30-seater aircraft, with hybrid electric and hydrogen-electric propulsion. In addition, a five-year memorandum of understanding was also signed in 2024 between Groupe ADP, Dassault Aviation and DFS aimed at strengthening their decarbonisation action at Paris-Le Bourget Airport in a number of areas including: u the use of electrical equipment for all ground operations (refuelling, taxiing, towing, etc.); u the use of geothermal energy to power airport buildings and hangars.
