APFIVE A researcher studying the efficiency of clean coal technology focused on carbon capture and storage (CCS) as a method to reduce CO2 emissions. They concluded that CCS could eliminate CO2 emissions from coal-fired power plants. What mistake did the researcher make?
They should have concluded that CCS increases CO2 emissions due to the energy required for the capture process.
They should have focused on the reduction of SOx and NOx emissions, not CO2, when evaluating clean coal technology.
They correctly concluded that CCS can eliminate CO2 emissions, making coal a clean energy source.
They overestimated the efficiency of CCS; while it significantly reduces emissions, it does not eliminate CO2 emissions entirely.
