1. Green hydrogen is primarily produced by:
a) Coal gasification
b) Methane
c) Renewable electricity
d) Natural gas reforming with carbon capture
Answer: c) Renewable electricity
1. Green hydrogen is generated via water electrolysis powered entirely by renewables like solar or wind, making it a zero-carbon fuel.
2. Water molecules are split using electrical current into hydrogen gas at the cathode and oxygen gas at the anode.

a) 2 MMT
b) 5 MMT
c) 20 MMT
d) 50 MMT
Answer. b) 5 MMT
The National Green Hydrogen Mission aims to reach at least 5 MMT of annual green hydrogen production capacity by 2030, which was approved in January 2023.
3. How much associated renewable energy capacity addition is required by 2030 to support the National Green Hydrogen Mission in India?
a) 50 GW
b) 100 GW
c) 125 GW
d) 150 GW
Answer. c) 125 GW

5. Which correctly describes the difference between grey, blue, and green hydrogen?
a) Grey - renewable electricity; Blue - coal; Green - natural gas
b) Grey - natural gas without carbon capture; Blue- fossil fuel with carbon capture; Green - renewable electricity
c) Grey - coal with carbon capture; Blue - renewable electricity; Green - nuclear energy
d) All of the above
Answer: b) Grey - natural gas without carbon capture; Blue- fossil fuel with carbon capture; Green - renewable electricity
6. The SIGHT programme, associated with India's Green Hydrogen Mission, stands for:
a) Strategic Initiative for Green Hydrogen Technology
b) Strategic Interventions for Green Hydrogen Transition
c) Sustainable Initiative for Hydrogen and Green Technology
d) Strategic Investment for Green Hydrogen Transformation
Answer: b) Strategic Interventions for Green Hydrogen Transition
SIGHT is a major financial intervention under the National Green Hydrogen Mission. It supports areas including domestic electrolyser manufacturing and production of renewable/green hydrogen.
7. Which device is used to split water into hydrogen and oxygen using electricity?
a) Electrolyser
b) Transformer
c) Photovoltaic cell
d) Turbine
Answer: a) Electrolyser
An electrolyser uses electrical energy to drive the electrochemical splitting of water. Different electrolyser technologies.
8. Consider the following statements regarding green hydrogen:
1. Hydrogen itself is a primary energy source.
2. Hydrogen can serve as an energy carrier.
3. Green hydrogen can be converted into ammonia for use in fertilisers.
4. Green hydrogen can have applications in steel production.
Which of the statements given above is/are correct?
a) 1 and 2 only
b) 2, 3 and 4 only
c) 1, 3 and 4 only
d) 1, 2, 3 and 4
Answer: b) 2, 3 and 4 only
Hydrogen is a carrier/fuel rather than a primary energy source. It can be used to produce ammonia and has potential applications in sectors such as steel and refining.
9. Which one of the following is a major challenge in large-scale adoption of green hydrogen?
a) Lack of hydrogen's ability to store energy
b) High production cost and need for supporting infrastructure
c) Inability to use renewable electricity
d) Hydrogen cannot be used in industry
Answer: b) High production cost and need for supporting infrastructure
Important challenges include the relatively high cost of renewable hydrogen, availability of renewable electricity, electrolyser costs, storage and transport infrastructure, and creation of sufficient demand.
10. What distinguishes "Blue Hydrogen" from traditional "Grey Hydrogen"?
a) Blue hydrogen uses solar power, whereas grey hydrogen uses wind power.
b) Blue hydrogen is produced via electrolysis, while grey hydrogen uses coal gasification.
c) Blue hydrogen is mixed with green hydrogen for industrial applications.
d) Blue hydrogen utilizes carbon capture, utilization, and storage to capture the CO₂ emissions generated during production.
Answer. d) Blue hydrogen uses the same fossil-based SMR process as grey hydrogen, but captures and stores the resulting carbon emissions, reducing its carbon footprint.
