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.

  1. I and II only
  2. III only
  3. I, II and III
  4. None of the above statements is correct

Answer

Correct Answer

I, II and III

Explanation

Direct Air Capture (DAC) technology extracts CO2 directly from ambient air, which can be sequestered underground (carbon sequestration, I), used as a carbon feedstock in industrial processes such as plastics and food processing (II, e.g., carbonation), and combined with hydrogen to produce synthetic low-carbon aviation fuel (III). All three statements are correct.
