Which of the following statements with regard to Green Hydrogen is/are correct ?
1. It is decarbonized hydrogen obtained from natural gas reforming combined with carbon capture and storage (CCS).
2. It is produced using electrolysis of water with electricity generated by renewable energy.
3. National Green Hydrogen Mission of India aims for abatement of nearly 50 MMT of annual greenhouse gas emissions by 2030.
Select the answer using the code given below :

Result
Your answer: —  ·  Correct: B

Explanation

Statement 1 is incorrect. Hydrogen obtained from natural gas reforming combined with carbon capture and storage (CCS) is known as Blue Hydrogen. Green hydrogen involves zero carbon emissions during its production.

Statement 2 is correct. Green Hydrogen is produced through the electrolysis of water, splitting it into hydrogen and oxygen. For it to be 'green', the electricity used in this process must be generated from renewable energy sources, such as solar or wind power.

Statement 3 is correct. The National Green Hydrogen Mission, launched by the Government of India, aims to build a green hydrogen production capacity of at least 5 Million Metric Tonnes (MMT) per annum by 2030. The mission's official targets include the abatement of nearly 50 MMT of annual greenhouse gas emissions by 2030, alongside reducing fossil fuel imports.

Therefore, statements 2 and 3 are correct.

This is a highly predictable, medium-difficulty question. The core definitions of hydrogen colors (Grey, Blue, Green) and the specific targets of the National Green Hydrogen Mission (NGHM) are explicitly covered in standard texts like Shankar IAS and Nitin Singhania. Missing this means you are ignoring major flagship environmental policies.

Presence: 5/5
Why this source?
  • The National Green Hydrogen Mission document explicitly distinguishes between Green and Blue hydrogen.
  • It defines Green Hydrogen as being produced from renewable electricity via electrolysis.
  • It defines Blue Hydrogen as being produced via natural gas coupled with carbon capture and storage (CCS).

Presence: 5/5
Why this source?
  • The IEA provides the standard international color-coding for hydrogen production.
  • It clarifies that natural gas reforming with CCS is 'Blue' hydrogen, not 'Green'.
  • Green hydrogen is strictly defined as being generated by renewable energy sources.

Presence: 5/5
Why this source?
  • NITI Aayog's report on 'Harnessing Green Hydrogen' details the production pathways.
  • It confirms that the electrolysis of water using renewable energy is the pathway for Green Hydrogen.
  • It categorizes fossil-fuel based hydrogen with CCS as Blue Hydrogen.
