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.
Detailed Explanation:
Correct Answer: ✅ Option 3 (I, II and III)
Direct Air Capture (DAC) is an emerging technology that removes carbon dioxide (CO₂) directly from the atmosphere. The captured CO₂ can either be permanently stored underground (carbon sequestration) or utilized in various industrial applications, making it an important tool in climate change mitigation.
✅ Statement I is Correct: DAC can capture atmospheric CO₂ and store it permanently underground, helping in carbon sequestration.
✅ Statement II is Correct: Captured CO₂ can be used in the production of plastics, chemicals, beverages, and food processing industries.
✅ Statement III is Correct: In aviation, captured CO₂ can be combined with green hydrogen to produce synthetic low-carbon aviation fuels (e-fuels).
Short Notes: Direct Air Capture (DAC)
-
DAC removes CO₂ directly from ambient air.
-
It is considered a Negative Emission Technology (NET).
-
Captured CO₂ can be stored underground or utilized industrially.
-
DAC supports carbon sequestration and climate mitigation efforts.
-
CO₂ from DAC can be used to manufacture plastics, chemicals, and synthetic fuels.
-
Synthetic aviation fuels are produced by combining captured CO₂ with green hydrogen.
-
Major challenges include high energy requirements and operational costs.
