British driver Andy Green set a new world land-speed record for hydrogen-powered vehicles on Tuesday [3].
The achievement serves as a high-profile demonstration of the performance potential of hydrogen internal-combustion engines. By pushing the technology to extreme speeds, the project aims to prove that hydrogen is a viable alternative for high-performance power plants.
Green, a 64-year-old retired Royal Air Force pilot, conducted the run at the Bonneville Salt Flats in Utah [1, 2]. The vehicle reached a speed of 653.908 kilometres per hour, which is 406.320 miles per hour [4].
The car is powered by a system delivering a combined 1,600 horsepower [5]. This power allowed the vehicle to maintain stability while accelerating across the salt flats. The run establishes a new benchmark for the specific vehicle category of hydrogen-powered cars [3, 4].
Green described the intensity of the experience during the record attempt. "The ground comes at you very, very quickly," Green said [6].
The project focused on utilizing hydrogen in an internal-combustion format rather than relying solely on fuel cells. This distinction is critical for engineers studying how hydrogen can be integrated into existing engine architectures to reduce carbon emissions without sacrificing power.
Green noted the significance of the milestone for the future of sustainable fuel. "We’ve shown that hydrogen can power a vehicle to break the sound barrier and set a new record," Green said [7].
“"The ground comes at you very, very quickly."”
This record shifts the conversation around hydrogen from purely efficient city commuting to high-output performance. By achieving over 400 mph, the project demonstrates that hydrogen internal-combustion engines can handle extreme thermal and mechanical stress, potentially accelerating the adoption of hydrogen in heavy industry and high-performance transport where battery weight is a limiting factor.
