please give ans​

Answer 1

Answer:

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.
