Hydrogen Explained as an Alternative Car Fuel
There are many alternatives nowadays to cars that run solely on fossil fuels. One such alternative car fuel is hydrogen. Although there are no cars that run on hydrogen as of now, researchers have taken the development of hydrogen fuel cells a long way and now this technology has become a viable alternative to fossil fuel based engines.
The idea behind hydrogen as an alternative car fuel is actually not a complicated one. The basis of this alternative fuel is the fact that if hydrogen and oxygen come into contact with each other then a reaction occurs that results in heat, electricity, electrical charge and water. In order for a car to be powered with hydrogen, a fuel cell is required and this functions just as a battery would and supplies the power when it is needed.
The greatest advantage of hydrogen fuel is that it is extremely clean, because the only byproducts are water and heat. The efficiency of hydrogen fuel cells are also very high and already average around 50%, which is more than double of what a fossil fuel powered engine manages. The sources needed to run hydrogen powered vehicles are readily available and sustainable which means that once this technology becomes standard, it most likely will be a very low cost fuel.
It is possible to modify regular combustion engines so that hydrogen fuel can be used, however, there are still not many available sources for this fuel type and what can be found is still to expensive, which is one of the biggest disadvantages of Hydrogen. This is only because hydrogen powered cars are not yet mainstream. That should change in the near future, though.
