Q16.
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.
Answer
C
Explanation
air capture (DAC) technologies extract CO2 from the atmosphere at any location, unlike capture which is generally carried out at the of emissions, such as a steel plant. The CO2 can be stored in deep geological formations or for a variety of applications. This is carbon Hence, statement I is correct. captured CO2 can be used as a feedstock for carbon-based materials. It can be used in the of cement, plastics, carbon fibers, and other applications. This helps keep carbon stored in infrastructure, preventing its release into the for extended periods. DAC-captured CO2 be used for applications like carbonation in and as a food preservative. Hence, statement is correct. air capture (DAC) can be a source of carbon for with hydrogen to create synthetic low- fuels, a technology that is increasingly being for decarbonizing aviation. This process, also as Power-to-Liquid (PtL) or e-fuel production, renewable electricity to split water into hydrogen oxygen, then combines the hydrogen with CO2 from the atmosphere via DAC to produce gas, which is further processed into synthetic fuel. Hence, statement III is correct.
