Question

With reference to 'Direct Air Capture', an emerging technology, which of the following statements is/are correct?It can be used as a way of carbon sequestration.It can be a valuable approach for plastic production and in food processing.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.

Accepted Answer

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