New Coal Technology Harnesses Energy Without Burning, Nears Pilot-Scale Development

COLUMBUS, Ohio—A new form of clean coal technology reached an important milestone recently, with the successful operation of a research-scale combustion system at Ohio State University. The technology is now ready for testing at a larger scale.

For 203 continuous hours, the Ohio State combustion unit produced heat from coal while capturing 99 percent of the carbon dioxide produced in the reaction.

Liang-Shih Fan, professor of chemical and biomolecular engineering and director of Ohio State’s Clean Coal Research Laboratory, pioneered the technology called Coal-Direct Chemical Looping (CDCL), which chemically harnesses coal’s energy and efficiently contains the carbon dioxide produced before it can be released into the atmosphere.

“In the simplest sense, combustion is a chemical reaction that consumes oxygen and produces heat,” Fan said. “Unfortunately, it also produces carbon dioxide, which is difficult to capture and bad for the environment. So we found a way to release the heat without burning. We carefully control the chemical reaction so that the coal never burns—it is consumed chemically, and the carbon dioxide is entirely contained inside the reactor.”

Dawei Wang, a research associate and one of the group's team leaders, described the technology’s potential benefits. "The commercial-scale CDCL plant could really promote our energy independence. Not only can we use America's natural resources such as Ohio coal, but we can keep our air clean and spur the economy with jobs," he said.

Though other laboratories around the world are trying to develop similar technology to directly convert coal to electricity, Fan’s lab is unique in the way it processes fossil fuels. The Ohio State group typically studies coal in the two forms that are already commonly available to the power industry: crushed coal “feedstock,” and coal-derived syngas.

The latter fuel has been successfully studied in a second sub-pilot research-scale unit, through a...

Or we could just let it go and let it feed the vegitation like it was designed to do. Just sayin’... ;)

[Out of curiosity—how is carbon dioxide recycled? Fed to plants?]

It’s shipped to a Red state and released in the dead of night.

No, no, you are doing it all wrong big guy. First you hang them...by their toes of course. THEN you whip them within an inch of their lives. Then you whip them some more. Then you drop them in shark infested waters...or in a hog pen if your name is Henry.

I must concur... and only wish my name were "Henry," because that sounds like alot of fun!!!
