Question

Consider the following statements Statement I: Hydrogen is considered as a clean automobile fuel for future. Statement II: Hydrogen is the most abundant element in the universe. In the light of the above statements, choose the correct answer from the Options given below

Options

  1. A Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I.
  2. B Both Statement-I and Statement-II are correct but Statement-II is not the correct explanation for Statement-I.
  3. C Statement-I is correct but Statement-II is incorrect.
  4. D Statement-I is incorrect but Statement-II is correct.
Show Answer

Correct Answer

B Both Statement-I and Statement-II are correct but Statement-II is not the correct explanation for Statement-I.

Model Answer

  • Hydrogen is the lightest and most abundant element in the universe, and it can be used as a clean fuel source. When burned, hydrogen produces water as a byproduct, making it a potential key player in reducing carbon emissions. Hence, both Statement I and II are correct. Although, Statement II doesnt explain Statement I.

Types of Hydrogen

  • Gray Hydrogen: Produced from natural gas through a process called steam methane reforming (SMR). This method emits a significant amount of CO2.
  • Blue Hydrogen: Also produced from natural gas, but the CO2 emissions are captured and stored using carbon capture and storage (CCS) technology, making it cleaner than gray hydrogen.
  • Green Hydrogen: Produced by electrolysis of water using renewable energy sources like wind, solar, or hydroelectric power. It is the cleanest form of hydrogen, as it produces no carbon emissions.

Production Methods

  • Electrolysis: An electric current splits water into hydrogen and oxygen. When powered by renewable energy, this process produces green hydrogen.
  • Steam Methane Reforming (SMR): The most common method, where natural gas is combined with steam to produce hydrogen and carbon dioxide.
  • Gasification: Involves converting biomass or coal into hydrogen, carbon monoxide, and carbon dioxide at high temperatures.
