Hydrogen would be a great and clean fuel, but how do we store it ?
Hydrogen is the most common chemical element in the universe. And since it is involved in the transformation of energy on the sun, you don’t have to be a rocket scientist to realize it has a potential as a fuel. In the presence of oxygen, hydrogen is extremely flammable and it could therefore be used in combustion processes.
It is believed that hydrogen gas could be a strong candidate to replace fossil fuel in cars and as energy source also for very small devices, such as mobile telephones. Hydrogen is present in ordinary water, which we have lots of. When it combusts, it creates no carbon dioxide which would affect global warming.
However, there are some problems. Firstly, it takes a lot of energy to break out hydrogen from water. Secondly, hydrogen is evanescent and highly flammable, making it difficult to store and transport. Let’s hope that scientists figure these issues out so that we can start utilizing this easily accessible and environment friendly fuel !
