Clean Fuels Outlet Regulation

The Clean Fuels Outlet (CFO) Regulation is intended to provide outlets of clean fuel to meet the needs of those driving clean, alternative fuel vehicles. This program was initiated in 1990 and last updated in 2000. The program was originally designed with methanol, ethanol and compressed natural gas in mind to ensure that an appropriate number of fueling stations could dispense a designated fuel once a certain minimum number of vehicles using that fuel are certified in California to the Low Emission Vehicles (LEV) standard.  Since this time, LEV emission standards have continuously been met with conventional fuels; but LEVs alone are not enough if California is to achieve its long-term greenhouse gas and criteria pollutant emission reduction targets.  Modeling has shown that widespread penetration of zero emission vehicles (ZEV) is needed to achieve these targets.  ZEVs, specifically battery-electric vehicles and hydrogen fuel cell electric vehicles (FCEVs), will only be successful if customers can get fuel.  The greatest challenge to commercializing FCEVs is hydrogen fueling stations.

Following a December 2009 board directive, staff evaluated the CFO regulation and determined that it would be an appropriate tool to spur near-term hydrogen infrastructure development.  Staff proposed amendments to the CFO regulation in December 2011 as part of the Advanced Clean Cars Program, and re-noticed the proposal in February 2013.  Here you will find information on the original CFO regulation and proposed amendments to ensure that hydrogen stations are built in time to support commercialization of fuel cell vehicles.
