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 are designed to remove carbon dioxide directly from the ambient atmosphere. This captured CO2 can then be permanently stored underground or in geological formations, fulfilling its role in carbon sequestration (Statement I). Furthermore, captured CO2 is a feedstock that can be utilized in various industrial processes. For instance, it can be used in the production of synthetic fuels, chemicals, and even in certain food and beverage applications, and potentially in plastic production pathways (Statement II). When combined with green hydrogen, this captured carbon is crucial for producing synthetic low-carbon aviation fuels, addressing a key challenge in decarbonizing the aviation sector (Statement III).
