Question 65
With reference to 'Direct Air Capture', an emerging technology, which of the following statements is/are correct?
- It can be used as a way of carbon sequestration.
- It can be a valuable approach for plastic production and in food processing.
- In aviation, it can be a source of carbon for combining with hydrogen to create synthetic low-carbon fuel.
Select the correct answer using the code given below.
View correct answer and explanation
Correct answer: C
Correct Option: C (I, II and III)
Explanation: Direct Air Capture extracts CO₂ from ambient air. Captured carbon can be permanently stored, used as a feedstock for chemicals and food-industry applications, or combined with green hydrogen to make synthetic aviation fuels.
Statement / Pair / Item-wise Analysis:
I: True-capture plus geological/mineral storage is carbon removal.
II: True-captured CO₂ has industrial uses, including polymer feedstocks and food processing.
III: True-CO₂ plus hydrogen can produce electrofuels for aviation.
Option-wise Analysis:
A. Incorrect-omits III which the answer requires.
B. Incorrect-omits I, II which the answer requires.
C. Correct-this matches the facts and the item-wise assessment above.
D. Incorrect-omits I, II, III which the answer requires.
