UNH paper on the mechanics of widescale biodiesel production

Filed under: — adam @ 8:52 am

“In the United States, oil is primarily used for transportation – roughly two-thirds of all oil use, in fact. So, developing an alternative means of powering our cars, trucks, and buses would go a long way towards weaning us, and the world, off of oil. While the so-called “hydrogen economy” receives a lot of attention in the media, there are several very serious problems with using hydrogen as an automotive fuel. For automobiles, the best alternative at present is clearly biodiesel, a fuel that can be used in existing diesel engines with no changes, and is made from vegetable oils or animal fats rather than petroleum.

In this paper, I will first examine the possibilities of producing biodiesel on the scale necessary to replace all petroleum transportation fuels in the U.S.”
