Green Hydrogen — UPSC Prelims PYQ 2026

Which of the following statements with regard to Green Hydrogen is/are correct?

It is decarbonised hydrogen obtained from natural gas reforming combined with carbon capture and storage (CCS).
It is produced using electrolysis of water with electricity generated by renewable energy.
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:

1 only
2 and 3 only
1 and 2 only
1, 2 and 3

Explanation

Statement 1 is incorrect

Hydrogen obtained from natural gas reforming combined with Carbon Capture and Storage (CCS) is known as Blue Hydrogen, not Green Hydrogen. Green Hydrogen is produced without fossil fuels.

Statement 2 is correct

Green Hydrogen is produced through the electrolysis of water using electricity generated from renewable energy sources such as solar and wind power.

Statement 3 is correct

The National Green Hydrogen Mission aims to significantly reduce carbon emissions and targets the abatement of nearly 50 million metric tonnes (MMT) of annual greenhouse gas emissions by 2030.

It uses color-coded labels such as Green, Red, Blue, and Grey to indicate hydrogen types, with a side legend showing greenhouse gas impact levels from minimal to high, highlighting renewable and non-renewable sources like water, nuclear, natural gas, and coal.

PMF IAS Hack

Statement 1 can be eliminated easily by any aspirant having basic awareness of Green hydrogen. Hydrogen produced from natural gas with CCS refers to Blue Hydrogen, not Green Hydrogen. Once Statement 1 is eliminated, only the combination containing Statements 2 and 3 is left. So, even if one is not fully aware of Statement 3, the answer can still be reached through elimination.
