Consider the following statements regarding Carbon capture and storage...
The correct answer is option 'A', only one statement is correct.
Explanation:
Carbon capture and storage (CCS) technology is a process that aims to capture carbon dioxide (CO2) emissions from industrial sources, such as power plants and factories, and store them underground or use them for other purposes. Let's analyze each statement to determine which ones are correct:
1. Carbon capture and storage (CCS) involves complete removal of carbon dioxide from the atmosphere.
This statement is incorrect. The purpose of CCS technology is not to remove carbon dioxide from the atmosphere but to capture it from industrial sources before it is released into the atmosphere. CCS technology focuses on reducing CO2 emissions at the source rather than removing the CO2 already present in the atmosphere.
2. The technology is beneficial for the emissions that are hard to wipe out.
This statement is correct. CCS technology is particularly useful for reducing emissions from industries that are difficult to decarbonize, such as fossil fuel power plants and cement production. These industries produce large amounts of CO2 that are released directly into the atmosphere during their operations. CCS provides a way to capture and store or utilize this CO2, helping to reduce overall emissions.
3. The technology is used for fossil fuel plants and not for bioethanol plants.
This statement is incorrect. While it is true that CCS technology is commonly used for fossil fuel power plants, it is also applicable to other industries, including bioethanol production. Bioethanol plants produce CO2 emissions during the fermentation process, and CCS can be employed to capture and store these emissions as well.
In summary, only statement 2 is correct. CCS technology is beneficial for reducing emissions that are difficult to eliminate and can be applied to a range of industries, including fossil fuel plants and bioethanol plants. However, it does not involve the complete removal of carbon dioxide from the atmosphere.
Consider the following statements regarding Carbon capture and storage...
- Only statement 2 is correct.
- Carbon capture and storage (CCS) is a way to catch carbon and trap it beneath the earth. It is different to carbon dioxide removal (CDR) — where carbon is sucked out of the atmosphere — although some of the technologies overlap. The key difference is that CDR brings down the level of carbon dioxide in the atmosphere, cooling the planet, while CCS in fossil fuel plants and factories prevents the gas from getting out in the first place.
- In its latest review of scientific research, the Intergovernmental Panel on Climate Change (IPCC) found both options will be needed for emissions that are hard to wipe out.
- Some bioethanol plants, where the gas stream is pure, already report capturing more than 95% of the carbon emissions.
