Question

Consider the following heavy industries :Fertilizer plantsOil refineriesSteel plantsGreen hydrogen is expected to play a significant role in decarbonizing how many of the above industries?

Accepted Answer

Correct Answer: C — All three industriesStep-by-step Solution:Green hydrogen (produced via electrolysis using renewable energy) can decarbonise hard‑to‑abate sectors:Fertilizer plants: Ammonia production for fertilisers currently uses hydrogen from natural gas (grey hydrogen). Green hydrogen can replace it, zero‑carbon ammonia.Oil refineries: Refineries use hydrogen for hydrodesulfurisation. Switching to green hydrogen reduces refinery emissions.Steel plants: Green hydrogen can replace coal/coke as a reducing agent in direct reduced iron (DRI) processes, enabling “green steel”.Hence, all three major heavy industries can be decarbonised using green hydrogen.Why other options are incorrect:Option A (Only one): All three can benefit.Option B (Only two): Same reason.Option D (None): Green hydrogen is crucial for these sectors.Key Concept: India’s National Green Hydrogen Mission (2022) targets 5 MMT of green hydrogen production by 2030. Hydrogen use is dominated by oil refining and ammonia production; steel is an emerging sector. Green hydrogen is also considered for heavy‑duty trucking.
