give reason why hydrogen although has a high calorific value is commonly not used as a fuel
Answers
Answer:When hydrogen comes in contact with air, it reacts explosively. Hydrogen needs to be compressed at higher pressures. ... 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.
Explanation:
Answer:
1) Hydrogen is not obtainable directly from the atmosphere and requires processes like electrolysis which if needed on a large scale might need a lot of capital.
2) Hydrogen, being a gas requires huge tanks that can hold a lot of volume which takes up a lot of space.
3) Hydrogen, having the highest calorific value, is highly combustible making it very dangerous to use.
Hence, hydrogen is not a commonly used fuel although we can consider it as a potential resource.
