U.S. ethanol producers are being hit by a one-two punch: Hurricane Ike-related damage is softening demand for the alternative fuel while rising corn prices are increasing operating costs.

Last week, Hurricane Ike left many US oil refineries hobbled in its wake — including the nation’s largest biodiesel refinery. As a result, oil production is down.

Demand for ethanol in the US is closely tied to oil production because of the federal ethanol-gasoline blending mandate. So as oil production has fallen, so has ethanol demand.

At the same time as Hurricane Ike was downing oil refineries, corn futures — essentially the betting on whether or not the price of corn will rise or fall in the coming months — have risen dramatically due to the volatile financial markets and a general upward trend.

Texas biodiesel producer GreenHunter Energy says that hurricane damage to its gulf coast refinery — currently the largest in the nation — will take it out of production for 6 to 8 weeks.

The GreenHunter facility is capable of producing 100 million gallons of biodiesel per year (Mgy) using a combination of animal fats and vegetable oils. Prior to Hurricane Ike, they had been ramping up production and last Friday announced that they had achieved a 65 Mgy output. It’s unclear how the hurricane damage will affect their time frame for reaching full capacity.
