Question of the Day – INDIA’S FIRST PORT-BASED GREEN HYDROGEN PILOT PROJECT AT V.O. CHIDAMBARANAR (VOC) PORT
QOTD April 28,2026
With reference to green hydrogen, consider the following statements:
- Green hydrogen is produced using renewable energy sources.
- It involves electrolysis of water to produce hydrogen.
- It emits carbon dioxide during production.
Which of the statements given above is/are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 only
(d) 1, 2 and 3
Answer: (a) 1 and 2 only
Explanation:
Statement 1 is correct
Green hydrogen is produced using renewable sources like solar or wind energy.
Statement 2 is correct
Electrolysis splits water into hydrogen and oxygen using electricity.
Statement 3 is incorrect
Green hydrogen production does not emit carbon dioxide if renewable energy is used.
Why in news–
India’s first port-based green hydrogen pilot project has been launched at V.O. Chidambaranar Port as part of efforts to promote clean energy and reduce carbon emissions in the maritime sector. The initiative aligns with the National Green Hydrogen Mission and aims to demonstrate the use of green hydrogen in port operations, paving the way for decarbonization of shipping and logistics.
