EPA Seeks To Boost New Biofuels Even As Cellulosic Production Falters

摘要

Provisions in EPA's proposed renewable fuels standard (RFS) volumetric requirements for 2011 could boost new renewable fuels such as pulpwood biofuel, grain sorghum ethanol and canola oil biodiesel, but sources say the faltering cellulosic industry shows that RFS mandates on their own may not be enough to boost emerging fuels.rnSome industry officials argue that the cellulosic shortfall - which is tens of billions of gallons below what Congress mandated for cellulosic production in its 2007 energy law boosting the RFS - is due to a cap limiting the amount of ethanol in gasoline to 10 percent (E10).
