Question
With reference to 'Direct Air Capture', an emerging technology, which of the following statements is/are correct?
I. It can be used as a way of carbon sequestration.
II. It can be a valuable approach for plastic production and in food processing.
III. 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.
- A. I and II only
- B. III only
- C. I, II and III (Correct answer)
- D. None of the above statements is correct
Correct Answer
Option C — I, II and III
Detailed Solution & Explanation
The correct answer is I, II and III.
Key Points
- Direct Air Capture (DAC) extracts CO2 directly from ambient air.
- The captured CO2 can be: (I) stored underground for carbon sequestration; (II) used as feedstock in chemical synthesis including plastics and as a preservative in food processing (carbonation); (III) combined with hydrogen (made from renewables) to create synthetic aviation fuel (e-fuel/SAF).
- All three uses are correct.
