Which sector is a major target for CCS/CCUS deployments due to large emissions?

• A. Fossil-power plants
• B. Residential homes
• C. Agricultural fields
• D. Retail stores

Answer: (A)

The idea being tested is why CCS/CCUS targets emissions that come in large, concentrated sources. Fossil-power plants fit this best because they burn fossil fuels to generate electricity and release a lot of CO2 in one place. That makes capture at the source technically and economically feasible, using established methods to separate CO2 from the exhaust, followed by compression, transport through pipelines, and storage underground or use in products. In contrast, emissions from residential homes are dispersed and small per source, making large-scale capture impractical; agricultural fields produce other greenhouse gases like methane and nitrous oxide, which require different mitigation approaches; and retail stores, while energy-intensive, do not create the same large, centralized CO2 streams as power plants.
