During Paris 2024, a network of ten hydrogen refueling stations enabled Air Liquide to supply renewable hydrogen to fuel 500 Toyota Mirai vehicles and 5 buses transporting guests and athletes, covering a total distance of over 1 million kilometers. Additionally, 360 kg of renewable hydrogen powered electro-hydrogen generators at competition venues to support the cell phone network during specific events. The Paralympic Games' opening ceremony featured a hydrogen-fueled vehicle, highlighting the importance of clean energy. Air Liquide's collaborative efforts with partners like Toyota and the exceptional commitment of its employees played a crucial role in promoting hydrogen as a sustainable energy solution. The success of this initiative not only benefited the Paris 2024 event but also showcased the potential for hydrogen to contribute to the region's long-term sustainability beyond the games.
