Hydrogen as an alternate fuel for vehicles

Since last century engineers have been producing and testing FCVs (Fuel Cell Vehicles), the process to build them is very slow and expensive but will someday provide a car, which is able to run on hydrogen and oxygen outputting zero harmful emissions for the planet. Billions of dollars have already been spent on research and manufacturing and in a few years time experts claim that these vehicles will replace current gasoline-based automobiles. However, as any other commercial product on the market, the fuel cell cars have their advantages and disadvantages, which begs the question: Will hydrogen be an alternative to gasoline as a fuel for our cars in 20 years time?

Some might believe this is a great alternative to gasoline vehicles, since hydrogen constitutes for 90% of all existing atoms in the universe and we will therefore never run out of it, unlike oil. Yet, it is also the lightest element, thus any hydrogen that purely exists on Earth will shoot out instantly to space, therefore the only remaining hydrogen that exists on the planet is in water molecules and in natural gas. Fortunately, there are currently two
