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.
- AI and II only
- BIII only
- CI, II and IIICorrect
- DNone of the above statements is correct
Explanation
All three statements about Direct Air Capture (DAC) technology are correct:
I. It can be used as a way of carbon sequestration: Correct. DAC technology directly removes CO₂ from the atmosphere, which can then be permanently stored underground or in other forms, making it a carbon sequestration method.
II. It can be a valuable approach for plastic production and in food processing: Correct. Captured CO₂ can be used as a feedstock for producing various chemicals, including those used in plastic manufacturing, and as a processing aid in food industries (carbonation, preservation, extraction processes).
III. In aviation, it can be a source of carbon for combining with hydrogen to create synthetic low-carbon fuel: Correct. DAC-derived CO₂ can be combined with green hydrogen through power-to-liquid processes to create sustainable aviation fuels (SAF), helping decarbonize the aviation sector.
