Des Moines Register: Archer Daniel Midlands Co. said Tuesday it had reached an agreement for construction of a pipeline that would be used to capture and sequester carbon emissions from its eastern Iowa ethanol plants. It is the third carbon-capture pipeline proposed in Iowa. The Chicago-based agricultural products company said it signed a letter of intent with Denver-based Wolf Carbon Solutions, which would build the 350-mile pipeline serving ADM's ethanol plants in Cedar Rapids and Clinton. ADM said Wolf would develop, own and operate the pipeline. It would transport liquefied carbon dioxide to an underground sequestration site in Decatur, Ill.
