The Automobile Club de l’Quest (ACO) recently announced plans to transition the MissionH24 H24EVO prototype from gaseous hydrogen to liquid hydrogen for competitive racing at the Hyvolution event in Paris. The decision to switch to liquid hydrogen is driven by its better suitability for competition demands, with the H24EVO set to demonstrate this advancement. Originally unveiled in 2023 and showcased at the 2024 24 Hours of Le Mans, the H24EVO was initially designed with two gaseous hydrogen tanks storing 7.8kg at 700 bar to fuel the 300kW Symbio fuel cell. The shift to liquid hydrogen is expected to allow storage of 11-14kg at -253°C, potentially extending the vehicle's endurance from 25-30 minutes to at least 40 minutes. The updated MissionH24 timeline includes electric motor bench testing starting in October, with a physical model expected by February 2026 and a targeted top speed of 340km/hr. The motorsports industry, valued at $5.11bn in 2022 and forecasted to grow to $7.47bn by 2028, is increasingly focusing on reducing emissions and embracing hydrogen for sustainability. Major events like Formula 1 (F1) and MotoGP are witnessing significant viewer interest, prompting a shift towards environmentally friendly practices. F1, for instance, is striving for Net Zero Carbon by 2030, with new engine regulations from 2026 emphasizing sustainable fuels. The partnership between FIA and ARAMCO highlights ongoing efforts to innovate and enhance environmental performance in motorsports.
