The hydrogen-powered Irizar i6S Efficient Hydrogen coach has made history by completing a record-setting round trip between Ormaiztegi and Briançon in the French Alps, covering a total distance of 2,500 kilometers. This journey not only demonstrated the operational capability of the coach but also set a new benchmark for the longest distance traveled by a hydrogen bus in Europe. Passing through various cities in the Pyrenees and Provence, the coach overcame an elevation gain of over 1,400 meters, showcasing its performance in different terrains. With a range of 900 kilometers and quick refuelling stops of less than 20 minutes, the Irizar i6S Efficient Hydrogen could revolutionize long-distance travel if supported by suitable hydrogen infrastructure. Irizar's commitment to sustainable mobility is evident through the development of this hydrogen-electric coach, which has sparked significant interest in the potential of hydrogen as a clean alternative to fossil fuels. The company's readiness for series production of the coach and its emphasis on European partnerships highlight a promising future for clean technology adoption in the transportation sector. With the success of this journey, Irizar aims to lead the way in promoting clean technologies and sustainable mobility solutions for a greener future.
