Clean hydrogen to power cars requires fossil fuel energy

Some alternatively-fuelled power options are well-known now. Electric cars, for instance, are gaining popularity and are becoming a common sight on roads, especially within cities.

Hydrogen-powered cars, however, are a slightly rarer sight. The technology they use is in its relative infancy, which means not a lot is known about how they work and the benefits they bring. We’re going to find out.

First of all, just how do hydrogen cars work? Well, in fuel cell cars, power is generated by reacting hydrogen with oxygen. The energy that comes from this reaction is then stored in the car’s batteries.
