In some ways, hydrogen cars make a lot of sense. It's a readily available fuel source and refuelling is much quicker than charging an EV. The hydrogen cars already on sale also have longer ranges than electric vehicles. That said, the industry seems to be going more down the electric route. There are lots more electric car chargers than hydrogen filling stations. The cost of hydrogen cars are also very expensive. There'd have to be a huge swing in the industry if hydrogen cars were to become more mainstream than electric vehicles.
