Hydrogen from biomethane; gasoline & diesel from tree residue; cellulosic ethanol among new proposed California LCFS fuel pathways
December 18, 2015
California Air Resources Board (ARB) staff posted 32 new Low Carbon Fuel Standard (LCFS) fuel pathway applications for comments at the LCFS website. Among the multiple applications for different processing pathways of corn or sorghum ethanol are four pathways from LytEn for hydrogen produced from biomethane; four pathways for renewable gasoline and diesel produced from tree residue from Ensyn; and one application for cellulosic ethanol using corn stover feedstock from POET.
The LCFS is a regulation to reduce the carbon intensity (CI) of fuels sold in California by 10% by 2020. The LCFS applies to liquid and non-liquid fuels. If a product is above the annual carbon intensity target, the fuel incurs deficits. If a product is below that target, the fuel generates credits which may be used later for compliance, or sold to other producers who have deficits. So far, fuel producers are over-complying with the regulation. (Earlier post.)
