Today’s Alternative Fuel Choices: P-Series

P-Series is a relatively new alternative fuel. It is a blend of , methyltetrahydrofuran (MTHF), and pentanes, with butane added for blends used in severe cold weather.

Because both the ethanol and the MTHF can be produced from renewable biomass resources, emissions from producing and using P-Series are substantially less than those from .

P-Series was initially designed as a fuel to help fleets meet the U.S. ‘s requirement to purchase more AFVs. Therefore, P-Series will initially be sold to fleets. Eventually it will be avail- able to the general public too.
