E85A mixture of 85% Ethanol and 15% GasolineProsHigher Octane Rating 100-105Reduces dependence on OilReduces tailpipe emissionsUsually cheaper than 87 octane gasolineConsProduction process does add extra green house gases to atmosphereUse of corn crop for fuel instead of foodLower energy content than gasolineLimited distribution network

*

BiodieselVegetable oil or animal fat based diesel fuelComes in different mixtures, B20, B100Waste vegetable oil can be usedProsBurns cleaner than petro dieselLubricates very wellWVO sometimes freeReduces petroleum consumptionConsLower energy content than petro dieselFood or FuelUse of limited resources for crop productionNot a total replacement for petrolLimited distribution networkClearing of forest for biodiesel crops

*

HYDROGENBurned with OxygenBi product is water H2OProsMuch lower emissions than PetrolHuge supply of hydrogenReduce consumption of PetrolMore energy per weight than gasolineHigher thermal efficiency than gasoline engineConsMost common production method burns fossil fuelsLower volumetric density than gasolineExpensive to produceNo distribution networkDifficulties in transportation and storage
