Predicting the future is always risky. But it’s long been clear that vehicles are one of the main sources of air pollution that takes thousands of lives a year in the U.S. alone through lung disease, asthma, cancer and more. And that ultimately, the world would have to move toward vehicles that didn’t treat our shared air like a giant trash bin, emitting toxic substances every time they were powered on.
Two technologies could deliver vehicles with zero emissions: battery-electric powertrains and hydrogen fuel cells. For decades, hydrogen was presumed to be “the fuel of the future,” with electric cars limited to the niche of small, short-range urban cars.
That’s not how it’s played out. And as 2020 seems poised to be a big year for electric car development—pandemic aside—it’s worth examining how this happened - Link
