Q. 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.
Exp) Option c is the correct answer.
Statement I is correct: Direct air capture (DAC) is a method that can be used for carbon sequestration, also known as direct air carbon capture and sequestration (DACCS). DACCS involves extracting carbon dioxide (CO2) directly from the atmosphere using chemical or physical processes, followed by the long-term storage of that captured CO2, effectively removing it from the atmosphere.
Statement II is correct: Direct air capture (DAC) can be a valuable approach for certain aspects of plastic production and food processing by utilizing captured CO2. DAC extracts CO2 from the atmosphere, which can then be used as a feedstock for producing some types of plastics and in food production processes.
Statement III is correct: Direct air capture (DAC) technology can be used in aviation to create synthetic low-carbon fuels. DAC extracts carbon dioxide (CO2) from the atmosphere. This captured CO2 can then be combined with hydrogen, which can be produced through renewable energy sources, to create synthetic fuels like e-fuels
