Multiple choice

Which industrial process is most likely to benefit from fuel switching?

  1. Natural gas production and distribution

  2. Coal mining

  3. Landfills

  4. Wastewater treatment
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Natural gas production and distribution is the largest source of methane (CH4) emissions in industrial processes, and therefore has the greatest potential for emissions reductions through fuel switching.

  1. Post-combustion capture

  2. Pre-combustion capture

  3. Oxyfuel combustion

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A variety of technologies can be used for carbon capture and storage in industrial processes, including post-combustion capture, pre-combustion capture, and oxyfuel combustion.

Multiple choice

Which industrial process is most likely to benefit from carbon capture and storage?

  1. Iron and steel production

  2. Chemical production

  3. Petroleum refining

  4. Cement production
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cement production is a major source of carbon dioxide (CO2) emissions, and therefore has the greatest potential for emissions reductions through carbon capture and storage.
