Question

Hydrogen gas has the highest calorific value i.e., 150 kJ/kg, yet it is not used as a fuel. The reasons are:

• A. it is explosive in nature
• B. it causes storage problem
• C. it causes transportation problem
• D. all of the above

Answer 1

The correct option is D all of the above

When hydrogen comes in contact with air, it reacts explosively. Hydrogen needs to be compressed at higher pressures. This process is quite hectic which causes a storage problem. As hydrogen is combustible and has a storage problem, transportation is also a problem for hydrogen gas. Therefore, though hydrogen gas has the highest calorific value, it cannot be used as a fuel.
