Carbon Capture and Storage Efficiency
A researcher investigating clean coal technology concluded that carbon capture and storage (CCS) can eliminate all carbon dioxide (CO2) emissions from coal-fired power plants. Which of the following identifies a flaw in this conclusion?
A
They should have concluded that CCS increases CO2 emissions due to the energy required for the capture process.
B
They overestimated the efficiency of CCS; while it significantly reduces emissions, it does not eliminate CO2 emissions entirely.
C
They should have focused on the reduction of SOx and NOx emissions, not CO2, when evaluating clean coal technology.
D
They correctly concluded that CCS can eliminate CO2 emissions, making coal a clean energy source.
