This video and accompanying essay examine ways to reduce the environmental impact of burning coal. Two technologies are discussed: turning solid coal into a clean-burning fuel gas (syngas), and capture and storage of CO2.
Video length: 1:30 min.

About the Content
- The video gives an overview of coal electricity generation, clean coal technology, and sequestering carbon dioxide.
- Clean coal is an umbrella term used to describe technologies that may reduce CO2 emissions (e.g. sequestration, coal gasification, scrubbers).
- Provides statistics for overall annual U.S. coal consumption as well as average household usage, and then explains the need for developing a cleaner way to convert coal into electricity. [Note that coal consumption has been reduced nationwide since this video was produced.]
- While promising, most applications of clean coal technology are still not ready for implementation.
- Comments from expert scientist: It is a great idea to talk about the pros and cons of the coal industry and possible changes to technology both in terms of combustion technology and carbon capture. The Frontline documentary is a good place to start but I do not think the "background essay" is adequate.
