Explanation:
<u>Hydrogen is used as fuel in automotives . It yields very high energy on combustion. It has great energy density by weight but poor energy density by volume. This is because Hydrogen is a very light gas, approx. 11 times lighter than normal air.</u> Hence it would require large volume of container to store it at normal atmospheric pressure conditions. That is why it is compressed using external energy to increase its density and decrease the volume needed for storage . So it becomes portable.
Only problem in this approach is that it utilities about 20% energy of the Hydrogen's energy potential to compress it . But this method proves cost effective as it reduces the overall weight of the container and also gives space to vehicles .
