Biofuel Bubble Bursts:

The WSJ reports that the biofuel industry is introuble, billions in federal subsidies notwithstanding. Biofuels received greater subsidies than any other fuel source in 2007, according to the Energy Information Administration, but it was apparently not enough.

Domestically produced biofuels were supposed to be an answer to reducing America's reliance on foreign oil. In 2007, Congress set targets for the U.S. to blend 36 billion gallons of biofuels a year into the U.S. fuel supply in 2022, from 11.1 billion gallons in 2009. That would increase biofuels' share of the liquid-fuel mix to roughly 16% from 5%, based on U.S. Energy Information Administration fuel-demand projections.

Corn ethanol, which has been supported by government blending mandates and other subsidies for years, has come under fire for driving up the price of corn and other basic foodstuffs. While it will continue to be produced, corn ethanol's dominant role in filling the biofuels' blending mandate was set to shrink through 2022. Cellulosic ethanol, derived from the inedible portions of plants, and other advanced fuels were expected to surpass corn ethanol to fill close to half of all biofuel mandates in that time.

But the industry is already falling behind the targets. The EPA, which implements the congressional blending mandates, still hasn't issued any regulations to allow biodiesel blending, though they were supposed to start in January. The mandate to blend next-generation fuels, which kicks in next year, is unlikely to be met because of a lack of enough viable production.

"I don't believe there's a man, woman or child who believes the industry can hit" the EPA's 2010 biofuel blending targets, says Bill Wicker, spokesman for Sen. Jeff Bingaman of New Mexico, chairman of the Senate Energy Committee.

Biodiesel producers are scrambling for yet more government support to bail them out, and are likely to get a receptive hearing. Farm-state senators are calling for action, and the Administration promises more grants and loans for "green" biofuel projects -- and corn barrel politics continue.
