Correct answer: (b) 2 and 3 only
Explanation
- A
1 only
1 only: This statement incorrectly defines Green Hydrogen. Hydrogen produced from natural gas reforming combined with carbon capture and storage is classified as Blue Hydrogen, not Green Hydrogen.
- B
2 and 3 only
(x) Official key: 2 and 3 only. Statement 2 is correct because Green Hydrogen is produced through the electrolysis of water using renewable energy sources such as solar or wind power. Statement 3 is also correct as the National Green Hydrogen Mission targets the abatement of nearly 50 MMT of annual greenhouse gas emissions by 2030.
- C
2 only
2 only: This option is incomplete because it omits statement 3, which is also correct regarding the emission abatement targets set by the National Green Hydrogen Mission of India.
- D
1, 2 and 3
1, 2 and 3: This option is incorrect because statement 1 describes Blue Hydrogen rather than Green Hydrogen, making statement 1 factually wrong in this context.
Summary. Official key is (b) because Green Hydrogen relies strictly on water electrolysis powered by renewables, and India's national mission officially targets an annual greenhouse gas emissions abatement of nearly 50 MMT by 2030, while natural gas with CCS constitutes blue hydrogen.
