Consider the following heavy industries:

1. Fertilizer plants
2. Oil refineries
3. Steel plants

Green hydrogen is expected to play a significant role in decarbonizing how many of the above industries?

  1. Only one
  2. Only two
  3. All three
  4. None
Show answer

Answer: C. All three

Verdict

All three industries can be decarbonized using green hydrogen → Option (c) All three.

Analysis

Green hydrogen is the hydrogen produced through electrolysis of water using electricity from renewable sources. Hydrogen use today is dominated by industry, namely: oil refining, ammonia production, methanol production and steel production.

India is prioritising green hydrogen as a potential solution to decarbonise hard-to-abate sectors such as refinery, ammonia, methanol, iron and steel and heavy-duty trucking.

Statement by statement

Statement 1 – CORRECT: Fertilizer plants use ammonia production which is a key application of green hydrogen — green hydrogen can help decarbonize this sector.

Statement 2 – CORRECT: Oil refineries are a core application area — oil refining is one of the hard-to-abate sectors where green hydrogen is expected to play a major decarbonization role.

Statement 3 – CORRECT: Steel plants (iron and steel) are explicitly mentioned as a sector where green hydrogen is expected to play a significant decarbonization role.
