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.
Explanation
Direct Air Capture (DAC) is a technology that removes carbon dioxide (CO₂) directly from the atmosphere and either stores it or reuses it for various applications.
Statement I is correct. DAC can be used for carbon sequestration when the captured CO₂ is stored underground, helping reduce the overall concentration of greenhouse gases in the atmosphere.
Statement II is correct. The captured CO₂ can act as a raw material in industries. It can be used in the production of plastics, carbonated beverages, and other food processing applications, reducing dependence on fossil-based carbon sources.
Statement III is correct. In aviation, the captured CO₂ can be combined with green hydrogen to produce synthetic low-carbon fuels such as e-fuels or sustainable aviation fuel (SAF), helping decarbonize the sector.
Thus, Direct Air Capture enables both carbon removal and carbon reuse, making all three statements correct.
