Q In addition to airplanes, where else can hydrogen energy be used? A Cars can do the same. Hydrogen-powered cars use hydrogen instead of gasoline as fuel for car engines, which is 20% more efficient than gasoline. There are two types of hydrogen-powered cars, one is a full hydrogen-burning car, and the other is a hydrogen-blended car that burns a mixture of hydrogen and gasoline. The former consumes hydrogen quickly and can only run a few kilometers; the latter can improve the combustion of the entire engine. In many Chinese cities, traffic is congested and car engines are often overloaded, so using hydrogen-blended cars is particularly beneficial. In general, hydrogen-powered cars are very clean and ideal means of transportation.
