Australia Goes All-in on Green Hydrogen

Cars That Think

For several months now, 20 teams of Australian high-school students have been designing fuel-cell cars to compete in the country’s inaugural Hydrogen Grand Prix. The task: make the most of a 30-watt fuel cell and 14 grams of hydrogen gas. And while coal plants still supplied over half of Australia’s power in 2021, change is afoot.
