A hydrogen powered car is actually an electric car. The particularity is that, instead of storing the electrical energy in batteries, it generates its own electric power on board through a fuel cell powered by hydrogen, providing significant advantages.The main difference is that emissions are water vapour, which means there is no CO2 and therefore it produces zero emissions. Its system works by expanding gases caused by combustion.
Hydrogen is not an energy source but an energy vector. This means we can use energy to isolate hydrogen, store it, and then use that hydrogen to produce energy again. What it can’t be done is to obtain pure hydrogen directly from the environment, because this element has a particular tendency to combine with others and it practically can not be found isolated on Earth.
With the actual industrial process to obtain hydroge, CO2 emissions are similar to…
