1. What is the main purpose of Carbon Capture and Storage (CCS) technology?

   • A. To create new types of fuel from air
   • B. To capture carbon dioxide emissions and store them underground
   • C. To plant trees automatically using robots
   • D. To cool down the Earth by reflecting sunlight

2. Which of the following is a common source of CO2 that can be captured using CCS?

   • A. Ocean waves
   • B. Solar panels
   • C. Cement factories
   • D. Wind turbines

3. Where is captured carbon dioxide typically stored in CCS projects?

   • A. In the upper atmosphere
   • B. In deep underground rock formations
   • C. In large above-ground tanks
   • D. In the ocean near coastlines

4. What happens to CO2 when it is injected deep underground for storage?

   • A. It turns into solid rock immediately
   • B. It remains as a gas forever
   • C. It becomes a supercritical fluid and gets trapped in rock pores
   • D. It dissolves into groundwater and disappears

5. Which natural process does CCS mimic to keep CO2 underground?

   • A. Volcanic eruptions
   • B. How oil and gas have stayed trapped underground for millions of years
   • C. Photosynthesis in plants
   • D. Formation of clouds

6. What is 'Direct Air Capture' (DAC)?

   • A. Capturing CO2 directly from the atmosphere using machines
   • B. Capturing CO2 from factory smokestacks
   • C. Planting forests to absorb CO2
   • D. Collecting CO2 from car exhaust pipes

7. Why is CCS considered important for reaching net-zero emissions?

   • A. It allows unlimited fossil fuel use with no consequences
   • B. It can reduce emissions from hard-to-decarbonize industries like steel and cement
   • C. It replaces the need for renewable energy
   • D. It cools the planet directly like an air conditioner

8. What is a key safety feature of underground CO2 storage sites?

   • A. They are located in active volcanoes
   • B. They are monitored with sensors to detect leaks
   • C. They use plastic balloons to hold the gas
   • D. They are only used for one year

9. Can captured CO2 be used for anything useful before storage?

   • A. No, it must be buried immediately
   • B. Yes, it can be used to make products like concrete, fuels, or carbonated drinks
   • C. Only for making dry ice
   • D. Only in greenhouses for plants

10. Which country operates the world’s first large-scale CCS project on a coal-fired power plant?

    • A. Germany
    • B. Canada
    • C. Australia
    • D. Japan
