[EXAMINER REASONING]

1. Trap: Confusing Green Hydrogen with Grey or Blue Hydrogen.
2. Confused Point: The efficiency loss during the conversion process.
3. Anchor: Electrolysis using renewable energy.
4. CA Hook: SIGHT (Strategic Interventions for Green Hydrogen Transition) program.
5. Mains Hinge: Reducing import dependence on Natural Gas and Crude.

Core Concept

Green Hydrogen is produced by splitting water into hydrogen and oxygen using an electrolyzer powered by renewable energy (solar or wind). Unlike Grey Hydrogen (from natural gas) or Blue Hydrogen (with carbon capture), Green Hydrogen has zero carbon emissions.

India's National Green Hydrogen Mission aims to make India a global hub for the production, utilization, and export of green hydrogen, targeting 5 MMT per annum by 2030.

Key Facts

• Process: Electrolysis
• Primary Input: Renewable electricity and water
• Target: 5 MMT production by 2030
• Key Application: Steel, Refineries, Shipping (Hard to abate sectors)
• Policy: National Green Hydrogen Mission

Previous Year Questions

Statement Elimination Guide

• Correct: Green hydrogen is the cleanest form of hydrogen production.
• False: Green hydrogen is currently cheaper than grey hydrogen. (Incorrect. It is more expensive due to electrolyzer costs).
• Trap: Saying hydrogen can be extracted directly from the air. (Incorrect. It is extracted from water or hydrocarbons).
