For the first time, says engineering firm Alset Global, a hydrogen-powered car has undertaken a zero-emissions lap of an international motor race. An Aston Martin Rapide S racecar used Alset's hybrid hydrogen system on May 19-20 at the 41st ADAC Zurich Nürburgring 24-Hour race in Germany. It consists of a hydrogen fuel supply system, tank, and proprietary internal-combustion engine management system. The company says its hybrid hydrogen technology performed faultlessly throughout the race, and could find its way into a series-production vehicle within a couple of years. In the race, the car reached top speeds of about 160 mph (257 km/h) on pure hydrogen. Hydrogen was supplied by Linde via its TrailH2-gas mobile refueling truck. It was stored at 350 bar (5076 psi), and a full refill was reduced to just 30 s per pit stop by the end of the race, according to Alset.
