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 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
- D.None of the above statements is correct
▶ Answer & Explanation
Correct answer: C. I, II and III
Direct Air Capture (DAC) technologies remove CO2 directly from the ambient atmosphere. This captured CO2 can be permanently stored underground or in geological formations, serving as a carbon sequestration method. Furthermore, captured CO2 is a feedstock for producing synthetic fuels (like aviation fuel when combined with green hydrogen) and can also be utilized in various industrial processes, including the production of chemicals and building materials, and potentially in food and beverage applications.
