British driver Andy Green, the man who once broke the sound barrier in a car, is returning to Utah's Bonneville Salt Flats this week. He intends to attempt a new land speed record using a hydrogen-powered vehicle to showcase the fuel's potential.
From Supersonic Jets to the 350 mph Diesel Milestone
Andy Green's racing history is defined by extreme velocity and technological milestones. In 1997, he famously traveled faster than the speed of sound, setting an outright land speed record of 763.035 mph in a jet-powered vehicle. Those runs in Nevada's Black Rock Desert were so powerful they produced sonic booms felt in the nearby town of Gerlach.
Two decades after that supersonic feat,Green set another significant mark at the Bonneville Salt Flats. As the report states , he reached 350.092 mph in a diesel-powered car. This upcoming attempt represents a pivot from traditional fossil fuels toward hydrogen, marking a new chappter in his storied career as a former Royal Air Force fighter pilot.
The 1,600 Horsepower JCB Hydromax Challenge
The vehicle at the center of this attempt is the JCB Hydromax, a 32-foot-long, bright yellow machine designed by the British construction manufacturer JCB. The car's slim, pencil-like shape houses two hydrogen internal combustion engines. These engines, adapted from JCB's heavy construction machinery, produce a combined 1,600 horsepower by igniting pressurized hydrogen gas with air.
JCB has invested more than $134 million into this high-speed project to demonstrate the utility of hydrogen. JCB Chair Anthony Bamford has argued that hydrogen may be better suited for the heavy demands of industrial sectors than electric power. This project serves as a high-profile laboratory for that specific industrial thesis .
Targeting the 341.3 mph Electric Vehicle Benchmark
Green is not merely looking to beat his own diesel record; he is aiming to shatter multiple existing categories. The report notes that Green intends to clear the world record for hydrogen internal combustion engines, which currently stands at 185.5 mph. He is also targeting the electric vehicle land speed record of 341.3 mph.
While practice runs last week saw the Hydromax reach a top speed of 368.347 mph, the official attempt must meet strict criteria.. To earn the record,the run must be conducted on Tuesday in the presence of the Fédération Internationale de l’Automobile (FIA), the international governing body for motor sports.
Safety Concerns Over High-Pressure Gas and Hydrogen Sourcing
Despite the technological optimism, the project faces significant hurdles regarding safety and environmental purity.. Hydrogen combustion engines present unique risks due to the high pressure and flammability of the gas. Green has spent months training to manage these risks, including mastering the deployment of a parachute to slow the car on the low-friction salt crust.
There is also the question of how "green" this speed attempt truly is. While JCB has secured a deal to use hydrogen produced via renewable energy, the majority of the world's hydrogen is still derived from fossil fuels. Furthermore, as the source highlights, the team remains uncertain about what the absolute peak speed will be during Tuesday's official run.
