Part of the problem, the EPA says, is that suppliers have not created the biorefineries and thus not generated the production volume that was projected in 2005 when H.R. 6 was signed by then-president George W. Bush. "What's the hold up?" asked Nebraska representative Lee Terry. "I would have expected mass production by now," he commented during a hearing in May. In March, President Obama indicated a desire to get four new cellulosic ethanol refineries up and running by 2013.
Under the original plan laid out in H.R. 6, the U.S. should be using 1 billion gallons of cellulosic ethanol in 2013, a number also likely to be rolled back due to the lack of fuel available on the market, though the EPA says it will continue to evaluate the market and remains optimistic that celluloic ethanol will play a larger role in the nation's fuel mix.
