The MissionH24 H24EVO prototype is transitioning from gaseous to liquid hydrogen storage as it approaches its final design freeze later this year. This change is part of the MissionH24 project, driven by the Automobile Club de l’Ouest (ACO), to showcase hydrogen-powered prototypes in motorsport at Le Mans and in the FIA WEC by the end of the decade. The ruleset for manufacturers to compete with hydrogen prototypes is currently being developed in collaboration with interested parties, without a specific date for its public disclosure. The H24EVO, presented at Le Mans last June, will now store 11 to 14kg of liquid hydrogen at -253 degrees Celcius in insulated tanks, extending its driving range to “at least” 40 minutes. To align with the FIA’s focus on liquid hydrogen, the car’s top speed target has been raised to 211.3 mph, aiming to match GT3 performance levels. ACO President Pierre Fillon highlighted the importance of this shift towards liquid hydrogen at the recent ‘Hyvolution Paris’ exhibition, emphasizing the goal of zero CO2 emissions in motor racing. The timeline for the H24EVO includes a design freeze in May 2025, bench testing in October, final assembly in February 2026, and track testing in April of the same year, paving the way for its competitive debut.
