4 reasons why hydrogen cars just haven’t taken off yet

Hydrogen was at one point tapped as the best candidate for replacing internal combustion engines. Indeed, there are still a number of hydrogen-powered cars on the market, like the BMW iX5 Hydrogen, the Toyota Mirai, and the Hyundai Nexo. There are some advantages to them over purely battery-operated electric vehicles — they don’t lose range in freezing temperatures, and you can refuel in five minutes or less instead of waiting upwards of 30 minutes at a charging station. And while they do produce emissions, those include few if any greenhouse gases. They’re even touted as cleaning the air sometimes.
