Sound-barrier pioneer shifts to hydrogen for new Bonneville bid

Andy Green, the only person to break the sound barrier in a car, returns to the Bonneville Salt Flats with a hydrogen-powered JCB Hydromax aiming to beat the 350.092 mph diesel land-speed record and set hydrogen and electric LSR marks; he recently reached 368 mph in practice, with the official FIA validation expected during the attempt. The project showcases hydrogen as a potential clean-energy option, though green hydrogen currently accounts for a small share of production, and safety remains a priority.
