The U.S. Maritime Administration (MARAD) has granted $450,000 to AEP River Operations of St. Louis, Missouri, to modify the Motor Vessel (M/V) Christopher Parsonage into a fuel-efficient hybrid vessel that conserves fuel and reduces emissions. The modification will provide the 180-foot tug boat, which operates along the lower Mississippi River, with a hybrid generator set attached to the main engine that will provide auxiliary power, which would normally be produced from the diesel generator.
