Question
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?
Correct Answer — C
Explanation
Green hydrogen can meaningfully cut emissions across all three sectors: it can serve as a clean feedstock in ammonia production for fertilizers, replace fossil-fuel inputs in hydrocracking and refining processes, and act as a reducing agent in direct-reduction steelmaking, displacing coal or coke — making it relevant to all three heavy industries.
