Over the past decade, consumer preferences have significantly favored electric vehicles (EVs), with sales soaring to 18.5% of all new cars in the UK. This shift has been attributed to improved battery performance, expanded charging infrastructure, and the influence of EV racing like Formula E. With the impending ban on new fossil-fuel cars in the UK by 2035, attention has now turned to hydrogen as the next frontier. Extreme H, a new racing series set to debut in April 2025, will serve as a testbed for hydrogen technology in motorsport. Spearheaded by Alejandro Agag, the CEO of Extreme H and co-founder of Formula E, the championship aims to showcase the untapped potential of hydrogen as a sustainable energy source. The Pioneer 25, equipped with a 75kW hydrogen fuel-cell, promises thrilling performance with its 400kW output, 4.5-second acceleration from 0-100km/h, and a top speed of 200km/h. Teams will have the opportunity to customize bodywork, maintaining a balance between innovation and standardization. The transition to hydrogen racing has been well-received by industry figures like Jenson Button and Ian James, who see it as a positive step towards a greener future. Beyond the racing realm, Extreme H seeks to test and develop the hydrogen infrastructure, emphasizing hydrogen's potential for diverse applications. By venturing into Extreme H, the motorsport industry aims to not only demonstrate the viability of hydrogen but also foster a market for sustainable energy solutions.
