Which of the following is not a limitation for the use of hydrogen as a fuel?

  1. (a) An inexpensive method of producing hydrogen
  2. (b) A practical means of storing hydrogen
  3. (c) Hydrogen is explosive
  4. (d) A distribution system (hydrogen refueling stations)

Interpretation Introduction

Interpretation: It should be determined for the following statement not a limitation for the use of Hydrogen as a fuel.

Concept Introduction:

A fuel having higher calorific values is considered to be a good fuel.

Hydrogen gas has the highest calorific value of 150 KJ/g among all the fuels.

So the Hydrogen as is considers be an extremely good fuel.

But however, hydrogen gas is not used as a fuel in homes and industries.

Explanation of Solution

Reason for correct option

Hydrogen gas has the highest calorific value of 150 KJ/g among all the fuels.

So the Hydrogen as is considers be an extremely good fuel.

But however, hydrogen gas is not used as a fuel in homes and industries.

Percentage of hydrogen in the room = total volume of hydrogen produced / volume of the room

If this calculated value is in the range of 4% - 75% (v/v) then there danger of an explosion.

Hydrogen is far less dense than air and if it escapes from a breached container, it would rapidly dissipate, moving up and away from the source of the leak. The time frame and location in which a combustible mixture would exist would be limited compared with a gasoline leak cause explosion.

The Hydrogen is very explosive in nature and Uncontrollable, so it hard to use as Fuel like fossil...
