Iowa needs $2 billion in coal-fired electricity production to supply power for ethanol; critics say coal use “ungreens” ethanol

January 30, 2008

Two coal-fired electricity plants, in Marshalltown and near Waterloo, have been proposed in Iowa to provide electricity for the growing collection of Iowa ethanol plants. Critics say that ethanol’s need for coal-powered electricity makes the case that it is not a green fuel.

Alliant Energy, co-owner of the Marshalltown project, said that the needs of the ethanol plants can only be solved at this point in time by nuclear, natural gas or coal, and that natural gas is not economical while nuclear has been taken off the table due to environmental concerns. The proposed plants would cost $1 billion each.

Last week, Xethanol Corporation announced that it would invest $500,000 in Consus Ethanol for its cogeneration project that would provide power for its ethanol production process from waste coal, that would have a $0.48 per gallon cost advantage over comparable ethanol plants in the Midwest powered by natural gas. The Pittsburgh-based facility will distribute fuel to East Coast markets, which have higher prices for ethanol.

In another approach to solving emissions problems at coal-fired power plants,  Linc Energy and Bio Clean Coal said they would joint venture on an algae-based biodiesel plant in Australia using CO2 emissions from coal-fired electricity generation.

    1. Coal-Powered Ethanol: A Dirty Shade of Green « Earth2Tech on February 12th, 2008 12:56 pm

      [...] Ethanol: A Dirty Shade of Green Written by Katie Fehrenbacher No Comments Posted February 12th, 2008 at 8:56 am in Energy The ethanol industry must be in a pretty badstate if cheap and dirty coal plants need to be built to sustain it. The Oil Drum and Biofuels Digest say that two coal-powered plants are being proposed in Iowa, partly to provide power for the state’s ethanol producers. Everyone knows that corn-based ethanol is far from sustainable, but it doesn’t get much dirtier than that. [...]
