Whereas most Tesla Superchargers take more than an hour to deliver enough charge for a range of 300 miles, hydrogen fuel stations could pump hydrogen gas into a car's tank in as little as five minutes. This gas is then gradually mixed with oxygen inside the car, producing an electro-chemical reaction that offers comparable cruising range to a tank of gas -- around 430 miles, Toyota claims -- with no waste products other than water vapor. If there's a downside to hydrogen, it's the complexity and cost of gathering, storing and delivering hydrogen at high pressure. Toyota says that it'll only sell its new car in areas that have some level of hydrogen refueling infrastructure already. However, with Tesla's Superchargers being so cheap to build and maintain (especially ones that are solar powered), Toyota may find that launching a commercial hydrogen fuel cell car turns out to be the easy part, compared to the daunting task of ensuring that its customers are always near a fuel station.
