The OFS would require that 50 percent of new automobiles in 2014, 80 percent in 2016, and 95 percent in 2017, would be warranted to operate on non-petroleum fuels in addition to or instead of petroleum based fuels. Compliance possibilities include the full array of existing technologies – including flex fuel, natural gas, hydrogen, biodiesel, plug-in electric drive, and fuel cell – and a catch-all for new technologies. This requirement will then provide certainty to investors to produce alternative fuels and fueling stations to have a variety of pumps supplying those alternative fuels.
