Proposed Modified Text for the Proposed Regulations for So Called Low Carbon Fuels
This notice is regarding the proposed modified text for the proposed regulations for so called low carbon fuels.
These are primarily Ethanol and Hydrogen obtained from natural gas.
As Dr. Wattenburg has pointed out, low carbon fuels such as Ethanol have much lower energy content than gasoline, for a given volume, so you have to burn much more of the low carbon fuel in a vehicle than you would gasoline to travel the same distance.
The result is that the carbon emissions per mile are very similar whether the fuel is gasoline, ethanol or a mixture of the two.
The other low carbon fuel is hydrogen which currently is obtained primarily from natural gas.
As Dr. Wattenburg has also pointed out, there are substantial carbon emissions when natural gas is used as the feedstock for the production of hydrogen.
Carbon=Energy. Nevertheless, The Air Resources Board is bound and determined to remove energy from our fuel. They have posted a Second 15-Day "Notice of Public Availability of Modified Text and Availability of Additional Documents and Information to Implement the Low Carbon Fuel Standard". The regulatory documents for this rulemaking are available online at this ARB website: http://www.arb.ca.gov/regact/2009/lcfs09/lcfs09.htm
Further inquiries regarding this matter should be directed to Mr. John Courtis, Manager of the Alternative Fuels Section, at (916)323-2661.
