Hi
hydrogen compound are abundantly available on earth and it has high calorifi value but this is not used as a common fuel give in 2 reason wt r the process that r being developed to use hydrogen as a common fuel.

hydrogen compounds are not used as fuel because of resons are
1. it is not safe to use in domestic use.
2. it can damage the whole equipment with its high heat.

Hydrogen is not use as a common fuel because=
1 - It takes a lot of energy to produce. You have to run a lot of electricity through water to break it down to hydrogen and oxygen. It can also be recovered from fractionating oil when producing fuels, but it is mixed with other gases and has to be purified. Then it has to be compressed and cooled. It’s most useful form is liquid hydrogen, giving far more energy content than as a highly compressed gas. The container has to be thick walled and insulated, therefore heavy, and a means has to be made to safely alleviate excess pressure due to boil-off.
2 - You need to transport it from the manufacturing plant to the refueling stations. That means heavy trucks, because a pipeline is unworkable. That is a major safety issue. Propane and LNG have similar safety issues, but are safer to transport than hydrogen.
3 - Hydrogen burns without any color to indicate a fire. This becomes a problem refueling your vehicle, because the slightest leak at the nozzle can catch fire without any notice. You don’t refuel by simply putting the nozzle in the filler tube. There has to be a better than an airtight seal made first, then an air purge of the fill hose, and after the fill a purge of hydrogen in the fill hose before you can disconnect.
After it’s in your vehicle, it is a great fuel.
Hope this helps you
