With reference to hydrogen as a fuel, consider the following statements:
The first pilot project of the National Hydrogen Mission is based on green hydrogen.
Hydrogen can potentially replace coal and coke in iron and steel production.
Fuel cell electric vehicles (FCEVs) powered by hydrogen fuel produce no tailpipe emissions.
Which of the statements given above is/are CORRECT?
2 only
1 and 2 only
2 and 3 only
1, 2, and 3
1, 2, and 3
Hydrogen is a versatile clean energy carrier. Green hydrogen is produced via water electrolysis using renewable energy, and it serves as a carbon-free alternative in industrial processes and mobility.
Hydrogen is a versatile clean energy carrier. Green hydrogen is produced via water electrolysis using renewable energy, and it serves as a carbon-free alternative in industrial processes and mobility.
Think of hydrogen as a 'rechargeable battery' for the planet; you put clean energy into it, and you get pure water and energy back when you use it.
G-I-Z: Green (Renewable), Industrial (Steel), Zero (Tailpipe emissions).

In electrolysis, an electric current splits water: 2H2тАЛO(l)тЖТ2H2тАЛ(g)+O2тАЛ(g). In Fuel Cell Electric Vehicles (FCEVs), hydrogen reacts with oxygen in a PEM (Proton Exchange Membrane) fuel cell, where the only output is water vapor: 2H2тАЛ+O2тАЛтЖТ2H2тАЛO+energy. In steelmaking, hydrogen acts as a reducing agent to remove oxygen from iron ore (Fe2тАЛO3тАЛ), producing water instead of carbon dioxide.
Green hydrogen is defined by the use of renewable energy sources for electrolysis.
FCEVs are distinct from Battery Electric Vehicles (BEVs) as they generate electricity onboard.
Hydrogen-based steelmaking eliminates the heavy dependence on fossil fuels like coking coal.
Zero harmful tailpipe emissions
High energy density per unit mass
Deep decarbonization of hard-to-abate sectors
High cost of production and storage
Infrastructure complexity for transport
Energy conversion losses during electrolysis
Steel and heavy manufacturing
Heavy-duty transport (trucks, ships, trains)
Chemical feedstock for ammonia production
Standard hydrogen is classified by colors based on production: Green (Renewable), Grey (Natural Gas without CCS), Blue (Natural Gas with CCS).
Option D is the correct answer because all three statements align with current scientific and policy developments under the National Hydrogen Mission.
D is correct тАФ All three statements accurately describe the production, utility, and environmental benefits of hydrogen as a clean fuel.
When answering environment-related questions, always link 'Green' hydrogen to 'Renewable' energy sources. If energy comes from coal, it is 'Brown' or 'Grey' hydrogen, not 'Green'.
