Kentucky Power plant uses algae to eat CO2 emissionsSubmitted by Chris Concomitantski on Sun, 11/10/2013 - 19:37
BURLINGTON, Ky. (AP) -- A Boone County power station is using algae to eat the carbon dioxide emissions from its smoke stacks.

The procedure begins with a line connected to the flue gas stack atop Duke Energy's East Bend Station. The flue gas is pumped into a feed tank where it feeds algae bubbling away in 8-foot tall tubes.
The algae consumes about half of the carbon dioxide in the flue gas. It has to be harvested periodically. Researchers say potential uses for the algae include feedstock, fertilizer and biofuel.
