- C2 only
- D1, 2 and 3
Show answer
Answer: (B) 2 and 3 only
The correct answer is 2 and 3 only.
Key Points
- Statement 1 is incorrect. What it describes is Blue Hydrogen, not green. Blue hydrogen comes from fossil fuels like natural gas through Steam Methane Reforming (SMR), but adds Carbon Capture and Storage (CCS) to trap the carbon dioxide produced. Green hydrogen uses no fossil fuels at all.
- Statement 2 is correct. Green Hydrogen is made by electrolysis of water, using electricity from renewable sources such as solar, wind or hydropower. Water splits into hydrogen and oxygen, with zero carbon emissions.
- Statement 3 is correct. The National Green Hydrogen Mission was launched by the Government of India in 2023. It targets a production capacity of at least 5 MMT (Million Metric Tonnes) per year by 2030. This is expected to cut nearly 50 MMT of annual greenhouse gas emissions.
Additional Information
- Hydrogen Color Spectrum:
- Grey Hydrogen: The most common method today. Extracted from natural gas by reforming, but the carbon dioxide escapes into the atmosphere.
- Brown/Black Hydrogen: Made by gasification of coal or lignite. Worst for the environment because of heavy CO2 release.
- Yellow Hydrogen: A subset of green hydrogen where the electrolysis runs specifically on solar energy.
- Pink Hydrogen: Electrolysis powered by nuclear energy.
- Mission Components:
- SIGHT Program (Strategic Interventions for Green Hydrogen Transition): gives financial incentives for making electrolyzers in India.
- Green Hydrogen Hubs: regional clusters for large-scale production and use.
- Energy Independence: aims to cut fossil fuel imports by over 1 lakh crore and attract investments of over 8 lakh crore by 2030.
India's National Green Hydrogen Mission launched in 2023 targets 5 MMT annual production capacity and 50 MMT greenhouse gas emission reduction by 2030.
UPSC is testing the distinction between green hydrogen (renewable electrolysis) and blue hydrogen (natural gas with carbon capture) - a common conceptual confusion.
The question checks understanding of India's hydrogen strategy as part of energy transition and net-zero commitments.
Green Hydrogen Production
Environment Green Hydrogen electrolysis renewable energy
Green Hydrogen: Production Process & Key Features
Green Hydrogen is produced by electrolysis of water using renewable electricity
Process splits water into hydrogen and oxygen with zero carbon emissions
Completely fossil fuel-free production method
Renewable sources include solar, wind, and hydropower
What is Green Hydrogen
Green Hydrogen is the cleanest form of hydrogen produced entirely from renewable energy. Unlike other hydrogen types, it involves zero fossil fuels and produces no carbon emissions during manufacturing.

Zero carbon footprint throughout production cycle
Uses abundant water resources as primary input
Can be produced anywhere with renewable energy access
Scalable technology suitable for industrial applications
Supports energy storage for grid balancing
Trap: Statement 1 describes Blue Hydrogen (natural gas + CCS), not Green Hydrogen
Green Hydrogen uses NO fossil fuels - only water and renewable electricity
Do not confuse electrolysis with Steam Methane Reforming (SMR)
Hydrogen Color Classification
Environment Blue Hydrogen natural gas reforming carbon capture
Hydrogen Color Spectrum: Production Methods & Carbon Footprint
Grey Hydrogen dominates current production using natural gas without CCS
Blue Hydrogen adds carbon capture to natural gas reforming
Green Hydrogen uses only renewable electricity and water
Colors indicate carbon intensity and production method
Classification Logic
Hydrogen is classified by colors based on production method and carbon emissions. The spectrum ranges from high-carbon Grey/Brown to zero-carbon Green, with intermediate options like Blue and Pink.
Hydrogen Types Comparison
Type | Production Method | Carbon Emissions | Key Feature |
|---|---|---|---|
Grey Hydrogen | Natural gas reforming (SMR) | High CO₂ release | Most common today (~95%) |
Blue Hydrogen | Natural gas + CCS technology | Reduced CO₂ | Transitional solution |
Brown/Black | Coal gasification | Highest emissions | Worst environmental impact |
Green Hydrogen | Water electrolysis + renewables | Zero emissions | Ultimate clean goal |
Yellow Hydrogen | Solar-powered electrolysis | Zero emissions | Solar-specific green variant |
Pink Hydrogen | Nuclear-powered electrolysis | Zero emissions | Nuclear energy variant |
UPSC Focus Areas
Blue vs Green distinction frequently tested in statements
Steam Methane Reforming (SMR) is the process for Grey/Blue hydrogen
Carbon Capture and Storage (CCS) differentiates Blue from Grey
Nuclear energy produces Pink hydrogen, not Green
Trap: Blue hydrogen still uses fossil fuels - only CCS reduces emissions
Green hydrogen requires renewable electricity - not just any clean electricity
Yellow and Pink are variants of green/clean, but Green specifically means renewables
