Australia Goes All-in on Green Hydrogen

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. They’ve been studying up on renewable energy, hydrogen power, and electric vehicles, preparing for the big day in April when their remote-controlled vehicles will rumble for 4 hours in Gladstone, a port city in Queensland. The task: make the most of a 30-watt fuel cell and 14 grams of hydrogen gas.
