The question this prepares you for · CSE 2026 · Q45
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.

Why revise these together?
The 2023 source is squarely load-bearing, teaching green hydrogen and decarbonization (statements 1-2 distinguishing green from grey hydrogen) and the greenhouse-gas source supports the National Green Hydrogen Mission emissions-abatement statement. The biomass-gasification source is a weaker generic renewable-energy link that does not teach electrolysis or green hydrogen specifically.
