उत्तर और व्याख्या · explanation in English
Answer: (c) I, II और III
Direct air capture (DAC) pulls CO2 straight out of ambient air. The captured CO2 can be stored underground, which removes it from the atmosphere, or used as a carbon feedstock for products such as food and beverages, chemicals and some plastics, and, combined with hydrogen, for synthetic aviation fuel. All three statements describe real uses.
- ✓ I Capturing CO2 from the air and storing it permanently removes it from the atmosphere; this is carbon removal by sequestration.
- ✓ II Air-captured CO2 can serve as a climate-neutral feedstock for a range of products, from food and beverages to chemicals, and some plastics are among the CO2-based products.
- ✓ III Air-captured CO2 combined with hydrogen is used to make synthetic hydrocarbon fuels, notably for aviation.
Remember · Direct air capture takes CO2 from ambient air: store it (carbon removal) or use it (food and beverages, chemicals, plastics, and synthetic fuels made with hydrogen).
