One of the pleasures of driving on the interstate highways is the breath of fresh air. The journey is more comfortable when there are several biofuel gas stations along the way, making sure you do not run out of fuel. The launch of the innovative four-state ‘biofuels corridor’ along Interstate 65 serve both these purposes efficiently. The highway connects the states of Alabama, Tennessee, Kentucky and Indiana and hits the Hoosier state at Jeffersonville and Clarksville. The biofuel pumps provide B20 and E85 fuels for vehicles with flexfuel tanks. Several such biofuel corridors are likely to be planned in the near future.
Fuel containing 20% biodiesel is called B20 and one with 85% Ethanol is called E85. B20 biodiesel can generally be used in normal diesel engines whereas E85 ethanol is used in engines modified to accommodate higher concentrations of ethanol. As compared to gasoline, E85 decreases greenhouse gas emissions, including the energy required to grow and process corn into ethanol by 15-20%, and shows up to 70% decrease in emissions when cellulose serves as base.
Not only in terms of decreasing emissions, but in terms of economic viability and working towards a green living concept that is widely applicable, increasing the number of biofuel corridor projects is definitely the need of the hour.
