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
The correct answer is that all statements I, II, and III are correct regarding Direct Air Capture (DAC). DAC is a technology that captures carbon dioxide directly from the atmosphere, making it a viable option for carbon sequestration (I). It can also facilitate the production of plastics and support food processing by supplying CO2 as a feedstock (II). Additionally, DAC plays a role in aviation by providing a carbon source to produce synthetic low-carbon fuels when combined with hydrogen (III). This interconnected application of DAC contributes significantly to the reduction of carbon emissions and supports various sectors, aligning with sustainable development goals discussed in UPSC syllabus contexts.
