Right now the EPA allows the oil companies to enjoy a 90% (actually now 85%) mandate. There really cannot be a contender against a product that enjoys that level of policy protection. Ethanol, cellulosic ethanol, biodiesel, algal biodiesel, biobutanol, you name it. None can contend if the government says they don't get market access based on cost competitiveness. Look how mad people get if they cannot sell their extra electricity into the grid because the sine wave is not 'pure'. We mostly agree that anyone who is making electricity should be able to sell the excess, but that is not the case with biofuels.
